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 - OLD 2013

Welcome to RadioKitGuide.com.  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.

Revised 2/20/2013 Added  K5BCQ & K5JHF Kits

Revised 5/21/2013 Changes  in Hendricks (2 new kits!), YouKits (1 new kit!), TenTec (New QRP rig coming soon), Four States QRP (1 kit retired, 1 coming soon), CR Kits (1 new kit!)

Revised 10/15/2013  Changes to YouKits (new kits), Ten-Tec, JUMA, Small Wonder Labs, Wilderness Radio, Dan's Small Parts and Kits, QRP.meWalford Electronics (new kits), Kanga UK (new kit), and Kits by EA3GCY (new kit).  Added BlekokQRP, and The Ham QRP DIY Shackon AliExpress

Revised 12/14/2013  added quite a few new vendors!  Marked in the list below with a "*"    Added list of vendors (to be linked at a later date), and alphabetized the whole guide.

Take The Heathkit Survey!
Heathkit is trying to return as a supplier of kits and accessories.  They are surveying people to get an idea of what the market is interested in.  Take the survey here:  http://www.heathkit.com/survey/index.php/278489?lang=en

Enjoy, and feel free to email me any corrections, or additions.--Neil W2NDG (w2ndg -at- radiokitguide -dot- com)

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.com  http://wb6dhw.com/For_Sale.html  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.
