Ramp Season (with a recipe)

It's that time of year again.  Ramps are rampant in the woods (sorry).  For those of you that don't know what
Flickr:Jessica and Lon Binder
a ramp is, the pictures here will help you identify them.  They are the wild relative of the cultivated leek that springs up in the Northeast towards the end of April.  Usually growing in moist woods.  If you know of a place where there is a lot of skunk cabbage, chances are that there are ramps nearby (usually a short distance in the opposite direction of the wet area that the skunk cabbage is near).  Pull the whole plant out by digging underneath it a bit, and you'll have something that resembles a lily of the valley on top, and a scallion on the bottom.  It should have a nice, pronounced garlicky-onion odor.  Drop these in a bag as you harvest, and try not to take too many from one area.  I usually bring a cooler to put them in once I get back to the car to keep them fresh until I can prepare them.

To prepare, cut off the small roots along with the bottom eighth-inch or so of the bulb.  Strip the outer layer or two of the translucent skin off and throw in a colander.  Wash thoroughly in cold water.  Then, chop the ramps into small pieces, tops and all, and re-wash in the colander in cold water.  You are now ready to prepare.

You can use them as you would leeks, with obvious consideration to the size difference, and the addition of an almost greens-like vegetable with the tops intact.  One popular use is in omelets.  I use them in place of the leeks in my leek latkes:

-A bunch of ramps, chopped into 1/2 inch pieces at the top, and smaller near the bulb.
-Almond meal (this makes them a bit healthier.  You can use bread crumbs instead.)
-Salt and Pepper
-Olive oil
-Frying oil

I use Trader Joe's almond meal.  Best for the dollar I think, and I usually saute the leeks in extra virgin olive oil, and fry the pancakes in regular olive oil, canola, or Trader Joe's rice bran oil.

Saute the prepared ramps in some olive oil until limp and fragrant, set aside to cool a bit, and wash the pan out for the next step.  Once they are just warm still, add a few eggs.  I had about 8 cups of chopped ramps to start with and used 3 jumbo eggs, so use your best judgement here.  You can always add more, so start low.  Mix well till the eggs are beaten, and add enough almond meal to make a thin pancake-consistency batter.  I think I ended up using about a cup this last time.  Add salt and pepper, and mix well.  Drop batter from a large serving spoon or ladle into hot oil (see above) and cook until golden brown on both sides.

These are fantastic as is, or with some sour cream, and/or applesauce.

I think next I'm going to try them in this recipe.

Happy foraging folks!

Nissequogue River State Park QRP expedition

I’ve been to this creepy state park several times since moving to Long Island.  Why creepy?  Mostly the abandoned buildings from the previous tenant on this property; The Kings Park Psychiatric Center.  So, crumbling scary buildings, and a great view of the Nissequogue River Inlet?  Is there a better place for a Sunday afternoon QRP outing?  I think not!

While I was here last time, I spotted a great spot for a QRP setup.  At the top of the long hill, and past the courtyards is a nice grassy area that terminates at a fence at the top of a 40 foot cliff over the water.  There are a number of trees for antenna hoisting, two picnic tables, and a great unobstructed view into the inlet and the Long Island Sound beyond.

I set up on one of the tables, and raised a vertical antenna high into the nearest tree using my twine and water bottle/counterweight, and later I put up a nice high end-fed.  I’m using a Xiegu X1M radio, with an Emtech XM-2 tuner.  Along with the main components are a small amplified speaker, mic, key, different counterpoise and/or ground methods, a 7″ Android tablet, and a portable jumpstart battery for power.  It was a perfect day.  I made 6 phone contacts with 5 Watts on 10, 15, and 17 Meters.  UK, Scotland, Mexico, Italy, The Azores, and Austria.  Not bad.  The weather was great, and I only got a few funny looks from walkers, bikers, and dog walkers as they heard me speaking into the mic.  The ghosts of patients past left me alone too.  One nice surprise was that there was an Optimum Wifi hotspot somewhere nearby, with enough signal to get me online without using my phone as a hotspot.  Great for QRZ lookups.  I have an Empire Park Pass, so admission was free, although I’m still amazed that they charge people to walk around this strange place.

Here’s a few pictures of the setup:

QRP: More fun than a barrel of microphones

I have been slowly getting into QRP these days (low-power for you beginners).  Being an outdoorsy kind of guy, it mixes well with my outings.  What has really surprised me lately though, is how well you can do with some inexpensive equipment, and a simple antenna. 

Most of my portable setup is relatively inexpensive.  For a radio, I am using a Xiegu X1M.  I paid around $300 for the radio, which is shipping in a newer version now (the platinum model) from Import Communications for $349.  The Xiegu is a general coverage receiver (100Khz-30MHz) with the ability to transmit 5 Watts SSB & CW on 80, 40, 20, 15, and 10.  It will transmit on other bands, but not cleanly without some external low-pass filters.  It’s also far from a perfect rig, being in the early stages of development.  It seems at times that the early adopters are actually beta-testing this rig for the manufacturer.  Most of the problems though can be corrected through some self-alignment using the menus, and those that cannot be corrected yet are all related to CW mode, which I am not currently using.  Even with the shortcomings though, I have had a lot of fun with this li
ttle radio.  I’m not here to necessarily recommend this model to everyone, but the tinkerers among us, looking for a TINY rig with these capabilities will enjoy the Xiegu.  There are other choices, which I’ll cover later, but first the rest of my setup.

For a tuner, I did a lot of reading and research.  I wanted something light, small, inexpensive, and with lots of positive reviews.  The Emtech ZM2 fit the bill perfectly.  This little tuner seems to be able to quickly tune up anything from my wire-in-the-trees setup, to a 4-drawer file cabinet.  It  handles up to about 15 Watts, and is available with either SO-239 or BNC connectors, and in kit form ($65), or assembled ($90).  Either model also has binding posts for balanced input.  Available from

For power, I’m currently running the radio off of the car.  I have a nice coiled extension, and I just plug in to the rear 12V jack in our Kia Soul.  I am planning on getting something more portable.  The radio seems to be sensitive to low-voltage and has issues with anything under about 11.5 volts, so I’ll probably go with a 24V dual-battery setup with a regulator.  For now, I’m happy just tailgating. 

My antenna is a stiff piece of solid wire, about 7 feet long, which is attached to about 50 feet of stranded 16 gauge wire.  I raise the antenna vertically in a tree using the water-bottle-and-cord method.  I tie the cord to the water bottle, which is about ⅔ full, and heave it at the top of a sturdy tree, allowing it to fall down the other side, and draw the cord up into the tree.  I then pull the cord back until the water bottle is at its highest point, attach the wire, and let gravity raise the wire into the tree.  When finished you just untie the cord from the bottle and pull it all back out from the antenna end.  I usually have a 10-20 foot counterpoise heading in an opposite direction from the ZM-2 tuner.  This setup allowed me to tune up on 10, 15, 20 Meters, as well as 17, and 12, but as I mentioned earlier, the Xiegu needs some extra filtering there.

I have a small straight key, just for tuning up, a small amplified speaker (the volume is a bit weak on the Xiegu for outdoor use), stock microphone, and I usually keep the laptop nearby feeding off the WiFi hotspot on my phone for QRZ lookups, and logging.  Most of this fits into a foam lined case that I picked up at a yard sale recently for $1.

How does it perform?  This was the way I setup the rig this past Saturday up in back parking lot in West Hills Park, off of Highhold Drive, which is near the highest point on Long Island (Jaynes Hill).  The Parking lot sits at about 360 feet above sea level (as determined by an app on my phone, so I wouldn’t use that number for surveying).  I worked stations in Denmark, Germany and the UK on 15M, and another Denmark station on 20M.  Not bad for 5 Watts. 

What options are there in QRP Sideband rigs?  Well, for you big spenders, there are the current popular models.  The Yaesu FT-817nd, the Elecraft KX3, and the TenTec Argonaut IV.  The Yaesu can be had for $650 after rebate right now, which is a pretty good deal.  The Elecraft and the TenTec are both around $1000, depending on accessories.  The Elecraft is a personal favorite of mine.  I hope to own one at some point. 

The Xiegu, as I mentioned is currently around $350.  There are a couple of new options coming in the next month or two that are similar in size and performance to the Xiegu.  The YouKits TJ-2B MK II is due the end of this month.  The MK II is an updated version combining the best bands of the two separate MK I models.  The MK II will cover 60, 40, 20, 17, and 15 Meters with 5 Watts, and costs $329 assembled on a special pre-order deal, with a free battery.  I’m thinking that I might have waited for one of these if I had known.  They usually offer a kit version with all SMD parts finished for $50-$75 less. 

LNR Precision, the company that currently owns the excellent Par EndFedZ antenna line, is about to release it’s QRP sideband rig, the LNR-FX4.  This rig will transmit on 40, 30, 20, and 17 Meters with 5 Watts.  It looks TINY in the photos.  LNR says that it will sell for less than $500.

For those of you that like to say “I built this rig, and have the burn scars to prove it!”, there are a few other options as well.  Hendricks QRP kits offers the BitX20A, BitX17A, and Survivor 75 Rigs.  Hendricks radios are always highly regarded and sell for between $100 and $200 depending on options. in the UK offers the MKARS80 SSB Transceiver.  This kit is based on the same design that is used in the BITX20 from Hendricks, but modified for 80 meter use. Covers from 3.5 to 3.8 Mhz with about 5 Watts output.  Ranging from a basic no-case kit for £55.00 shipped to the USA, to full kit with connectors, knobs, and an undrilled case for £68.50 (Pounds)

CR Kits from China, sells the KN-Q7a for $120 plus shipping ($45 more assembled).  5 Watts output, available in several 40 and 20 meter ranges.

Walford Electronics in the UK, sells several SSB and DSB (SSB compatible) kits in various level of difficulty.  I like this guy's website, as he explains each rig in depth.  Check it out!

EA3GCYvfrom Spain sells the ILER line of SSB kits.  These rigs have been reviewed well, and are inexpensive, and expandable.  Available in a couple of frequency ranges in 40 and 20 meters, they sell for €77.50 (Euros).  This might be my next project.  Looks fairly simple, thru-hole construction.

There's also the SDR kits from Tony Parks, although at 1 Watt output, they would be more of a challenge.  Tony is selling them assembled too these days (when available) on his website, as well as a nice little enclosure.

These kits, as well as others can always be found at my Radio Kit Guide directory at

There’s a guy who writes for (Larry W2LJ) who closes his posts with the line:  QRP - When you care to send the very least!  

Enjoy all.  73.

Low tech transmitter hunting

As I've mentioned before, KD2CHE and I belong to a local transmitter hunting group.  We get together one or two times a month.  One member will hide the nodopplerbox and give us a general area, which is usually a radius from a point (i.e. 2 miles from the intersection of routes 1 and 2 in Anytown, NY).  We are the only ones without doppler equipment, yet we almost always find the transmitter.  Here's some pointers for those of you that enjoy a bunny hunt every now and then, but may not think you can participate without sophisticated direction-finding equipment, or for those of you with dopplers that want to refine your techniques.

First of all, when I know the area, I print a map from the computer, and draw a circle for the hunting area.  Then, using either our knowledge of the area, or a combination of Google Maps, and Bing Maps, I find a large building that I can drive all the way around, as close to the center as possible.  I mark the spot on the map as our starting point.  KD2CHE drives, while I navigate.  When the time comes to leave for the location, I load up the equipment:
  • The mobile in the car, for communicating with the other hunters, an Icom IC-207H
  • An older Kenwood all-mode 2 meter mobile, with an RF-gain control, attached to an OPEK micro mag mount antenna
  • A smartphone with Google Maps, or a laptop with a broadband connection
  • Bright flash-lite
  • 1 HT set to the third harmonic of the hunt frequency, usually my Icom IC-T90A with a good antenna
  • 1 HT set to the hunt frequency with the antenna off, usually my Baofeng UV3R MkII
  • 1 HT set to the hunt frequency for KD2CHE to use out of the car
Once the transmitter is activated, KD2CHE drives slowly around the building at the starting point, stopping when the transmitter stops, and starting up again when it comes back (the one we use is usually 30 seconds on / 30 seconds off).  I mark the points in our loop where the signal was strongest and weakest, drawing a line with an arrow to get our initial vector.  Then we navigate in that direction, using Google Maps as a guide.  As the signal changes I mark the observed strength on the map.  When we reach the point where the signal strength goes back down, we determine the high point, and KD2CHE drives as close to perpendicular to the original route as she can. 

During this process, the RF gain control on the Kenwood comes in handy.  The box puts out a full 5 Watts, so as you get close to it, an un-attenuated receiver becomes useless.  For the signal readings with the RF gain all the way down, I write an 'A' in front of the s-meter reading on the map.  As the strength goes up again, we keep an eye on the 2 HTs.  When we're within 1 or 2 blocks, one or both of them will become active.  The third harmonic will usually not work until you are almost on top of the transmitter, which comes in handy.  This is when we start looking for a good spot.  In many cases there will be a public park, or area of some sort nearby, and the rest of the hunt is done on foot with the HTs, and the flash-lite  if necessary.  

Body shielding will get you a direction to walk in.  Hold a radio that is getting a weak signal (the IC-T90A has a fixed-level attenuator I can activate) close in to your chest and slowly turn around, and make note again of the weak and strong points in the circle.  Keep in mind though that sometimes, a good hider will put the box in a location that creates reflections and ghosts.  Sometimes you just need to use logic, or in the case of our last hunt, KD2CHE found the box simply by looking, while everyone else was wandering around the woods with Yagis and other fancy equipment.

Of course it helps to know the area, and to have some insight into where people like to hide things.  One of our hiders frequently hides in places he discovers while hiking.  Another likes to hide in very unique, and sometimes questionable places.  Once or twice we've had to explain to the authorities what we were doing.
I'm convinced that a doppler might enhance our abilities, but I'm afraid of relying on it too much.  We actually have one, but it needs some work.  We'll see.

73!  Neil W2NDG

Radio Kit Guide

Welcome to  Some time ago, I attempted to research sources for kits on the Internet, only to find out that there wasn't a one-stop-website for Ham Radio kit suppliers.

I decided to put together a good list of sources for kits that are currently available.  Many of these are for

Etherkit CRX1 Receiver
 QRP operation, but a few are full-featured professional transceivers (Elecraft, DZ).  On the beginners side there are a few sources that stand out:  Hendricks has a great assortment of kits, including some SSB QRP equipment.  QRPme offers the inexpensive, easy-to-build tuna-can products, and I would like to make special mention of the Four State QRP Group NS-40 which has the coils etched right into the PC board!  What a great idea!  I've covered transmitters, transceivers, and some receivers here.  Some accessories are mentioned in the source descriptions.

Revised 7/19/2012  Changes in Hendricks QRP Kits, YouKits, Genesis Radio, Tony Parks, and removed the coming soon designation on Heathkit.  I didn't check ALL of the prices, so don't hold me to total accuracy in that department.

Revised 10/22/2012  Changes in Hendricks, YouKits, Tony Parks, Small Wonder Labs, Wilderness Radio, and Four State QRP Group.  Removed Heathkit, Added HSC.

Revised 2/18/2013  Changes in Hendricks, YouKits, Tony Parks. Added CR KITS, and BreadBoard Radio.

-Walford Electronics  An impressive list of kits designed by UK Ham, Tim Walford (G3PCJ), as well as accessories.  Ships internationally.  All prices in British Pounds
·         The Berrow CW Transceiver.  A new specialist 1.5 W CW TCVR for any single band 20 - 80m that has a direct conversion receiver with the local oscillator derived by mixing the VFO with the output of a crystal oscillator and digital dividers for the chosen operating band - this provides genuine VFO operation, good stability and avoids chirp.  For setting up the VFO, you will need a counter or general coverage RX. The supply range is 9 to 16volts and the kit includes all parts to build it in a small upright but it can easily be installed in a case.  £59.00  + S&H            
·         The Lydford SSB Phone Transceiver.   Built for any single band 20 – 80m inclusive – your choice when you receive the kit! The RX has a doubled tuned RF filter that feeds a SA602 first mixer, which is followed by an IF amplifier prior to the 6 MHz five crystal ladder IF filter. This is followed by another SA602 for the CIO/product detector, and then two stages of audio amplification. Main tuning is by a PolyVaricon, with a potentiometer controlled varactor diode for fine adjustment. To help with the wide range of LO frequencies needed for the available bands, the kit contains a digital divider that is driven by the VFO for the lower frequency bands. The main PCB is a double sided 100 x 160 mm; the kit includes all front panel parts and a plain single sided PCB that you can lay out to your own design of front panel. £79 + S&H.
·         The Brendon Phone (DSB) Transceiver.  A phone transceiver project aimed at builders with limited experience where ease of assembly is important; the PCB has been laid out with plenty of space and it includes a small front panel.  It is normally supplied for 80m using a ceramic resonator VFO giving coverage of the lower half of the phone section of the band.  Consult with Tim for other bands.  The transmitter uses double sideband modulation, with a suppressed carrier - this is fully compatible with other stations using single sideband!  The robust IRF510 RF output transistor is mounted on aheatsink to make it more tolerant of abuse, and produces 1.5W of RF on a nominal 12 volt supply. The transmitter RF amplifier has its own RF drive control preset to ensure that the output stage does not limit on speech peaks. A double half wave filter removes the unwanted transmitter harmonics. The rig’s TR relay is controlled from the mike’s PTT switch and mutes the RX during transmission. There are many options for experiment and it can also drive the 10W Linear RF amp described in the Accessories section. The main PCB is double sided 100 x 100 mm. It needs an 9 to 16 volt supply. Price is £49 + S&H
·         The Bridgewater Superhet Receiver.   A sensitive phone superhet RX for any single band 20 - 80m. You decide which band to use it on when you get the kit!  The RX has supply protection and the kit includes a small PCB front panel. The main PCB is 100 mm square and can be easily boxed if you prefer. If you want to use it for CW, then add the Mini CW kit; for AGC, add the Mini AGC kit. The RX only price is £59.00 + S&H
·         The Burnham SSB Transceiver for Bridgewater.  This is the transmitter for the Bridgwater RX. Together they form a single sideband phone TCVR for any single band 20 - 80m. The TX has a speech amplifier suitable for dynamic microphones.  The Burnham output stage uses a robust IRF510 (with heatsink) that feeds the transmitter low pass filters and provides up to 1.5W pk of SSB output. There is provision also for driving the 10W Linear amplifier if you wish to add that. Like the RX, the TX can also be used with the Mini CW kit. The Burnham is a 100 x 80 mm PCB which must be mounted immediately behind the Bridgwater. This TX can only be used with the Bridgwater RX, so there is only one (discounted!) price for both - £84 + S&H\
·         The Brue CW Transceiver.  A builder friendly design with several advantages over earlier versions of direct conversion projects for those wanting to work CW. The parts are now laid out with more space making it much easier to build. It is a single band rig, normally for 80m (For bands other than 80m, up to 20m, you can fit a suitable QRP calling frequency crystal instead of the ceramic resonator but the tuning range will only be a few KHz).  Transmitter output is 1.5W using a 13.8 volt supply. It can be easily mounted in your own case if you prefer. There are many options for experiment and it can also drive the 10W Linear RF amp. The main PCB is doubled sided about 100 x 100 mm. It includes protection for reversed supplies which should be between 9 and 16 volts.  Price is £44.00 + S&H
·         The Tone Superhet Receiver.  An entry level superhet receiver project.  The Tone is for 80m phone operation. It has a 5 crystal ladder 6 MHz IF filter and double tuned RF filters to reject unwanted signals. The audio output stage can drive a small loud speaker or modern Walkman type 32R phones.  The receiver has reversed supply protection and can run off 9 to 15 volt DC supplies. While designed for phone use, it can also be used for CW, where the advantage of single sideband reception will be especially apparent - the band will appear far less crowded through elimination of the unwanted CW sidebands. For CW use, add the Mini CW kit; for AGC add the Mini AGC kit. The Tone kit includes all parts to build it in a small upright format. The matching SSB phone TX is the Parrett (below). The new 3D counter is recommended for those wanting a frequency readout. The Tone price is £44.00 + S&H
·         The Parrett Transmitter.  This is the matching transmitter to go with the Tone RX. It is also a superhet and provides single sideband phone operation on 80m. The RF output power is nominally 1.5 Watt when used on a 13.8 volt supply. The TX uses the VFO and CIO oscillator signals from the Tone to make operate on the desired frequency so that together they become a transceiver. (Hence the Parrett cannot be used on its own.) The TX has the same supply range as the RX and can share the supply protection.  The design also allows for use with the Linear RF amplifier for a higher RF output. The Mini CW kit can be added to provide all the facilities for CW operation. The Parrett is normally mounted immediately behind the Tone receiver (above). The Parret price is £35.00 + S&H but when ordered with the Tone, the combined price is discounted to £75.00 + S&H
·         Unavailable for now - being updated: The Cary Regenerative Receiver.  A new design of the old Regen concept but with an improved physical arrangement that makes it more easily used as a self contained unit! In its simplest form it is a single band receiver for either 80 or 160m, or the bottom part of Medium Wave band.  The kit includes a small speaker to get you going and it runs off a 9 volt PP3 battery or an external 12v supply.  For more advanced constructors, it can be converted to 3 band operation on 20, 40 and 80m. The basic 80/160/MW kit costs £34.00 + S&H. The 3 band optional extra kit is £6.00
·         The Yeo Direct Conversion Receiver.  An entry level direct conversion receiver that is capable of serious communication use! The kit includes parts so that you can make it for an any single amateur band 20 to 80m; this is done with alternative capacitor combinations and changes to the VFO inductor. There is a double tuned RF filter to remove out of band signals and the audio response is designed primarily for CW but is wide enough for phone also.  The kit includes a PP3 battery holder but can take any supply voltage between 9 and 16 volts DC - it includes reversed supply protection! The kit includes a small PCB mounted speaker (to get you going) but is able to drive an external 8R proper speaker or headphones.  Price is £33.00 + S&H
·         The Kilton CW Transmitter.  A simple CW transmitter to go with the Yeo receiver. It is normally 'crystal' controlled for use as a 'seperate' whose tuning is NOT linked to the receiver. It can do any band in the range 20 to 80m using your actual crystal or a ceramic resonator. It is supplied with a 3.58 MHz ceramic resonator for 80m use, which can be pulled or tuned down over about 50  KHz with the on board tuning trimmer. When a crystal is used, the pulling tuning range will be very limited. It produces 1.5 Watts on a 13.8 volts but can use a supply in the range 9 to 16 volts. When you order it with the Yeo or Cary RX, the relay is included and that can be mounted on the RX PCB. The circuit does not provide receiver sidetone.  The price is £19.00 + S&H
·         The Kilmot Phone (DSB) Transmitter.  This is the phone transmitter to go with the Yeo receiver! It provides double sideband (DSB) suppressed carrier phone signals which are fully compatible with any other station using upper or lower single sideband transmission - this approach makes everything rather simpler! Like the Kilton, it is normally 'crystal' controlled for use as a 'seperate' whose tuning is NOT linked to the receiver. It is intended really for use on 80m where the 3.69 MHz ceramic resonator gives a tuning range of about 50 KHz (down) using the on board tuning trimmer. (Other bands have to use crystals which makes its use very challenging!) On 80m it produces 1.5 Watts on modulation peaks with a 13.8 volts supply but can use anything in the range 9 to 16 volts. The output low pass filters are included together with provision for T/R relay control by your mike's PTT switch. Owing to lack of PCB space the T/R relay is not included, except when you order it with the Yeo or Cary RX, where there is space for the relay to be mounted. It is intended for use with the common sort of dynamic microphone.  The price is £24.00
·         -NEW-  The FiveFET Simple Regen TRF Receiver.  This is a simple Regen TRF aimed at first time builders of electronic projects interested in analogue radio. You start by making it work on medium wave, where the signals are large, so success comes easily! Then you can add the second band which would normally be 40m, where you can hear amateur stations from all around the UK and Europe. The two controls are for Tuning and setting the level of Regeneration. You will need a pair of modern medium impedance 32R phones, a PP3 battery, wire cutters, a small screwdriver and a soldering iron/solder.  £24 + S&H  WB6DHW carries the UHFSDR board and kit, plus several add ons and accessories. 
·         -NEW-  UHFSDR Transceiver.  The UHFSDR is a Software Defined Transceiver covering the 1.75 MHz to 700 MHz frequency range. A Si570 is used for frequency control. Two LVPECL 4 GHz max.flip flops produce I and Q LO signals at 1/2 the Si570 frequency. A pair of 1-1000MHz Double Balanced Mixers are used to convert signals to and from base band. A receiver pre-amp (2dB noise figure) and a transmit pre-amp(50mW max output) are provided as well as antennal switching plus provision for separate receive and transmit connections.  There is a Yahoo Group for support. The board is $10 shipped to the USA, and a mini kit is available with some components for $40 shipped to the USA.  There is an email contact listed for complete kits, but no price posted.

-Yoyodyne Consulting.  Yoyodyne sells the SR63ng, a clone of the retired SoftRock 6.3 SDR transceiver, for specific application.
·         -NEW-  SR63ng SDR Transceiver board.  The SR63ng is a clone of the older 6.3 version of Tony Parks' Softrock transceiver.  This is not meant to compete with Tony's newer products, but is available for use with the MOBO, a board that turns a 6.3 softrock into an all band  SDR transceiver.  $CAN 66.50 shipped to the USA or Canada.  Zao has one kit currently available.  He is also the source for the pre-built Soft66 SDR radios (currently selling new version LC4) which is one of the lowest-priced pre-built SDR receivers on the market.  Getting it running is a challenge I hear, but performs well for the money once you do.
·         Soft66Lite.  Small monoband SDR that can be built for different ranges depending on the bandpass components installed.  Easily switchable by plugging in homemade bp modules setup on IC sockets.  $20 shipped to USA
