Radio Kit Guide

W2NDG's UPDATED 2/14/2020

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.
Lidia 40M DC Receiver from QRPguys

I decided to put together a good list of sources for kits that are currently available. Many of these are for QRP operation, but a few are full-featured professional transceivers (Elecraft, DZ). On the beginners side there are a few sources that stand out: has a great assortment of kits.  QRPme offers the inexpensive, easy-to-build tuna-can products, and I would like to make special mention
of the Four State QRP Group Kits some which have 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.

Also Check Out:  W2NDG'sSources, Parts. Surplus Outlets, and More

A list of classic and radio-oriented surplus outlets online

Revised February 2020:  I've learned that updating the page is quite a chore, and I can't get to it as often as I like, but I will try to make a better effort at incremental changes this year.  There are several new listings worth checking out, including but not limited to, HFSignals (BITX), Multus SDR, Midnight Design Solutions.

A special mention to Dave Benson, who retired his company Small Wonder Labs, but is continuing to design rigs for other kit suppliers.  Check out his Hilltopper transceivers at 4SQRP, and the amazing new digital transceiver (a worthy evolution of the old PSK series) the Phaser at Midnight Design Solutions.

Enjoy, and feel free to email me any corrections, or additions.--Neil, W2NDG

-24hrsradioshop (eBay). This eBay seller does not have any Ham-related transmitter, receiver, or transceiver kits, but sells a variety of AM and FM radio kits, as well as a Morse code oscillator for soldering practice, or just personal enjoyment. Nice selection of variable caps too for your homebrew projects.

-ag6bd (eBay seller). This Thai eBay seller carries a variety of receivers, transceivers and accessories. As of this writing there are only a few items listed, but this varies up and down during the month. It would be impossible to list all of the items here, as many are not listed at the moment, and unfortunately there does seem to be a small language barrier. As I said, not everything is available all of the time, so check the completed listings for an idea of what might be coming, and check back often with ag6bd.

-Amateur Radio

  • • BITX Kits. Sunil sells several accessories for Ashhar Farhan's BitX kit and a few other boards and projects.  He is working on a new 3 band BitX based kit called BitX Easy.
  • • Cases for BitX40 and uBitX: These are professional metal cases for your HFSignals BitX radio projects to live in.  Nice quality!

-Amateur Radio Receivers.  David White, WN5Y offers his creations here.  The ELR Kit is a really neat radio using 21 functional LEDs.
  •  The Electroluminescent Receiver Kit. The Electroluminescent Receiver Kit is a superluminescent experience that uses very low noise devices, modern circuits that are documented in current literature, with boards designed to help the kit builder have a fun and educational experience. The receiver is a dual dual-conversion, dual dual-image superhet receiver that covers the 40, 30, 20 and 17 meter amateur radio bands. With minor modifications, the 41, 31, 19, and 16 meter SWL bands can be received. The interconnections are infrared and there are 21 functional LEDs that add to the circuit, not just tell you when it's on. And this radio has all the audio the average ham can use.  $89.95 + S&H 
  • •  Beginner and Experimenter's Receiver Kit.  This super hot receiver uses the latest in technology. The MMIC (monolithic microwave integrated circuit) amplifier works from just above DC to light. The BOO comes with all the parts you need to listen to WWV, or any frequency between 20 KHz and 200Mhz. This home grown, home-brew rig is fun, educational, and easy to build. The tuning range can be customized to cover an entire band or just a small segment. The KITBOO puts out 8 watts of audio, has a crystal filter, and features a broadband design. The PC board is silk screened for easy part ID. The manual comes on a CD complete with circuit theory, schematics, easy to read instructions, and much, much more. $49.95 + S&H

-Assorted Chinese kits on AliExpress  There are several version of each category all based on simple designs that most Hams know.  Crystal controlled kits come with crystals for 7023 kHz, but can be changed by the builder for any other 40 Meter crystal. Pixie requires one crystal, Frog needs two, and the Super RockMite needs three, all the same freq.

  • Pixie Kit 
  • Frog QRP Kit. 
  • Forty9er Kit.
  • Super RockMite Kit. 

-Borden Radio Company.  In addition to a couple of accessory kits like a crystal radio tuner, and QRM rejector, Borden has some nice Crystal and Regen radio kits. 

  • •  Dunwoody Crystal Radio Kit.  The circuit is based on a very selective and sensitive design that has been used since the very early wireless days. It employs an antenna/ground tuning capacitor to fine tune the input to the parallel tank tuning circuit for optimum selectivity and signal level. The air variable capacitor tuned parallel tank circuit is then adjusted to resonate at the desired frequency. The combination of these two air variable capacitor tuned circuits makes this set perform far and away better than regular single-tuned, or slider-tuned crystal sets.Nickel plated brass fahnestock clips are used for all connections. All parts, screws, washers, sandpaper, and wire are included in this fine quality kit.
  • •  Armstrong One Tube Radio Kit.  This little radio uses the best features of many famous one tube sets and has features not found on most radios of its type. One such feature is the capacitor coupling of the audio output . This feature prevents the "B" battery voltage from passing through the headset and possibly ruining the magnets. It also allows direct connection to amplifiers without further circuitry and also allows the use of ceramic earplugs when connected in series with a 10K ohm resistor. The capacitor coupling makes the detector more stable and reduces the "hand capacity" effect, thus making regeneration adjustment much easier. The special parts kits contain the American Made air variable tuning capacitor, in-circuit tested N.O.S. 3S4 vacuum tube,  tube socket, fahnestock clips, solder lugs, resistors, capacitors,  regeneration potentiometer with switch, coil form, mounting brackets, stand-offs, screws, magnet wire, hook-up wire,  knobs,  battery holder for "A" batteries, battery clips for "B" batteries, and the fine quality ready-to-finish routed basswood plaque for the base.  Everything is included to build your own Armstrong One Tube Radio except the batteries, headset and antenna. 
  • •  Pickard and FoxHole Crystal Radio Kits.  These are the classic old fashioned crystal radio kits.  The Pickard uses a standard diode detector, and the FoxHole uses a razor blade detector. 

-Breadboard Radio. Breadboard radio makes a few nice kits, all with a wooden breadboard –like base that the PC board attaches to when finished.

Those of you that know the track record of his high quality rig can only appreciate its reappearance to the amateur radio field. Kit comes with full detailed manual, schematics, and interconnection drawings and all components needed to complete board. This unit has a sensitivity greater than .1 microvolts for copyable code and is adjustable up to 2.0 watts. This unit is designed to cover the 40 meter band (7.000 to 7.250 mhz), but is also available in 20 and 30 meter versions.  A professional quality case with knobs and labeling is also available.

-Mike's Electronic Parts.   Mike is the source for Fahnestock Clips!  People are always saying how hard they are to find.  In addition, he is the expert on TRF AM-radio-on-a-chip components (MK-484 and derivatives) and stocks other radio construction items like Litz wire and varicaps.  He also has a couple of kits.

  • The MK484 AM Radio Kit 7 is a simple AM broadcast band receiver kit designed for the MK484 radio IC. This kit is not a beginners kit. MK484 Radio Kit 7 does require soldering and the ability to read a schematic. The kit is designed to allow a modular radio build. The RF tuning section is left off board to accommodate a variety of coil and capacitor combinations. The audio output can be connected directly to a high impedance earphone or headphone. We have tested this kit with magnetic and piezoelectric headsets 2,000 Ohms and higher with good results. The audio output could also be fed directly to an audio amplifier.  Available with several options and accessories.
  • There are also several crystal radio kit options, including a nice solder-less one for beginners.

-Mini Kits (AUS). Lots of accessories in kit form from down under. Bandpass filters, amps, and much more.  Their latest and most interesting product is the 630m Band 472 to 479kHz Transverter kit.

-Multus SDR.  Multus originally took over producing the Peaberry SDR, and expanded it into a multi-band 5 Watt transceiver for 160 thru 10 meters.  Watch for other products!

  • The Proficio is the next generation of Transceivers. It is an all band version (160M - 10M) transceiver.  It has all the features of our previous transceiver:

  •96kHz digital I/Q interface. No additional sound card needed. Only one USB connection is needed.
  •Two tone, 2 kHz spacing, third-order dynamic range: 99 dB.
  •Support for Elecraft T1 automatic antenna tuner.
  •External Amplifier control via AMP port.
  •CW Key Jack.
  •DG8SAQ/PE0FKO/SoftRock control interface.

-Nightfire Electronics.   Nightfire carries an assortment of accessory kits and an updated version of the Pixie available for beginners and clubs.  What I like about their offering here is that they have multiple 40 M crystals available, giving you a choice of operating frequency.

  • Pixie Transceiver kit.  This is the NightFire Electronics version of the very popular QRP Pixie CW Transceiver Kit. It is an upgraded version of the classic "PIXIE 4" low-power transceiver. The oscillator is crystal controlled with a little room for tweeking via a silicon diode being used as a psuedo varactor diode. This gives you some wiggle room. The transmitter will put out 360mWatts into a 50-Ohm load with a clean 12vdc input. The receiver works by using the output transistor as a mixer/detector and feeds the received signal into an LM386 Audio Amplifier. This will feed an 8 Ohm, 1watt speaker nicely. The Keyer is a switch to ground. The picture shows a simple push-button in its place, instead, it will come with a 2-pin screw terminal. 2-pin screw terminals are used for power input, Antenna output, Keyer input, and Audio Output. The PCB size is 2.5 inches x 2.5 inches. Double-sided, .062" with Plated-Thru-Holes. The bottom side is a good solid ground plane for RF noise reduction.

  • The Rockwell.  A simple Regenerative Tuned Radio Frequency (Regen TRF) receiver design for those just embarking on electronic construction projects; it is also suitable for Radio Club group building projects and You should be able to build it in a couple of evenings! It has two general coverage bands which can be chosen from MW or around 160m, and around 80m or 40m. These are chosen by alternative fittings for the four ready wound inductors.  Because it is a Regen TRF it is ideal for the powerful broadcast stations of the Medium Wave (and the 'short' wave) bands, using Amplitude Modulation, which can be easily heard with a short aerial; so start by building it for the MW as a good confidence booster! Because it is a Regen TRF it can also copy the common modes of Morse, and phone Single Sideband used by amateur radio enthusiasts. It has three controls - the Main tuning, and RF gain control and the Regen control. It uses four transistors arranged as an RF amp, the regen stage and two for the audio amplifier. The audio amplifier is designed specifically for modern 32R stereo phones which turn the RX on when plugged in and there is also very smooth control of the critical point of oscillation. The kit includes 5m of aerial wire for an initial 'throw-out' aerial which is usually enough for MW reception.
  • The Isle CW TX.  This is a 1.5W single band CW transmitter, that uses a crystal or, depending on band, a ceramic resonator for frequency control. The band can be any one of those in the 20 - 80m group. The kit includes a 3.58 MHz ceramic resonator for 80m which can be pulled over several tens of KHz down from the nominal figure using the on board trimmer. For the higher bands you have to use a crystal which means that the trimmer will then only have a very limited tuning range. The single band version is shown below with a single crystal, however there is space for three 'crystals' which can all be in the same band if you wish, so that the single harmonic filter on the Isle PCB will serve for all three frequencies. If the extra crystals are in more than the single band, you need extra low pass filters - using the Dual LPF kit. TR control of the aerial relay (it has to be mounted elsewhere due to lack of PCB space) is semi-break in from the key and includes facilities for muting the RX. If wanted, the TX can be driven by an external frequency source such as either mixer kit instead of using 'crystal' control.
  •  The Axe.  This is the transmitter for those wanting to get on the air quickly with DSB phone! It is entirely compatible with other stations operating single sideband! It produces a peak output of 1.5W when used on a nominal 12v supply. It is normally for any single band in the 20 to 80m group. Frequency control is by the included ceramic resonator for 80m giving about 50 KHz coverage down from 3.69 KHz with the on-board trimmer; for the higher bands where ceramic resonators are impractical, you will have to use a crystal with a tuning range of just a few KHz - the prototype (with crystal) shown below is for 20m. Ceramic resonator or crystal control would be appropriate for a simple RX where its VFO is at reception frequency, but the Axe can alternatively be driven by an external LO signal derived from a mixer kit! This avoids the limitations of 'crystal' control! A SA602 is used for the balanced modulator which then drives an AD8055 high speed op-amp. Because the gain through these stages vary with band, the single drive level preset has to be set for that band which means that the rig is limited to single band operation. The output stage has three BS170 MOSFETs operating in parallel - these are ideal for the LF bands where a standing bias current is needed linear operation! The standard Axe can also be used to drive an external liner amplifier. The output stage is followed by low pass harmonic filters and the control circuits include RX muting and control for the TR relay which has to be mounted elsewhere due to lack of PCB space.
  • The Ford.  This is a single band Direct Conversion Receiver that has been designed for builders wanting their first serious amateur band receiver. Normally I would suggest that it is built for the 40m band as this often has stations that are national as well as much longer distances when the propagation conditions are good. It is laid out with plenty of space around all parts and can run from a 9 volt PP3 battery or from an external nominal 12 volt supply. Much thought has been given to making it easy to build; there is a very detailed Project Construction Manual kindly compiled by Steve G0FUW who has run many Buildathons in recent years. The Manual can be downloaded here! (You may need to minimise this website in order to open the pdf file.) The actual kits are supplied with other important information such as the circuit, parts list, and the options for 20 or 80m bands. The PCB is 100 x 160 mm and only has tracks on the underside. The design has an RF gain control followed by a double tuned RF bandpass filter which feeds the product detector or mixer. The other input of this mixer (twin JFETs) is driven by the Local Oscillator that runs at band frequency and has both a Main tuning control (with the large knob) and a Fine tuning control to make it easy to resolve stations. Being a direct conversion RX allows it to receive Morse or normal phone SSB or even DSB! An Audio Frequency Gain control follows the mixer and feeds a two stage audio amplifier that is designed for modern lightweight 32R stereo phones. The provision of both RF and AF gain controls makes it much easier to deal with BCI which often plagues simple designs! Also because it has an RF amplifier stage, there is far less LO radiation which much reduces unwanted hum effects that are often problematical with DC designs!
  • The Culm.  This is a new CW TCVR for any single band 20 to 80m. On 80m it uses a ceramic resonator for the VFO giving several 10s KHz tuning range. The RX is direct conversion with a PolyVaricon for the main tuning and a voltage controlled diode for the Fine tuning beat note offset, which is automatically cancelled when you go to transmit. The RX has an RF amp with an RFG preset, followed by a double tuned RF filter and then a pair of JFETs for the product detector. This is followed by the first audio amp and a humped low pass CW filter centred on 725 Hz , which feeds the AFG pot and the audio power amp for a LS or phones. For transmission, the VFO feeds digital gates for the RF keying which then drive a buffer stage and a pair of BS170 MOSFETs in the output stage for a nominal 1.5W (with a 13.8v supply) on any band to 20m. The transmitter output has twin pi low pass filtering and the TR control circuits automatically disconnect the LPF from the RX RF amp when transmitting for click, and thump-free full break in changeover! There is also a 725 Hz sidetone oscillator, with adjustable level, that feeds into the RX audio amp. The 3.58 MHz ceramic resonator can be replaced by a crystal of your chosen frequency for the higher bands where ceramic resonators are not suitable, or by a 4 MHz resonator that can drive the Sim-mix kit fitted with a crystal to for any band output (including 5262 KHz!) up to 20m - this has the advantage of giving approx 50 KHz tuning range instead of the very limited range with a crystal.
  • The Sparrow.  This is a new crystal controlled transmitter that was originally designed for demonstrations of simple AM receivers in modern buildings, where reinforced concrete forms a Faraday cage preventing reception of external signals. But it can also be used as a normal transmitter with large external aerials working with Spaxton, Rockwell and maybe Ford RXs. It provides RF signals for speech using Amplitude Modulation; or Morse either by injecting a keyed 725 Hz audio tone into the AM speech amplifier for MCW, or ordinary plain interrupted carrier CW. The peak output power is nominally 1.5W on 13.8v supplies so the corresponding AM carrier power is 0.35W. The standard kit is for 160m using an 1843 KHz crystal with an IRF510 in the RF output stage; other bands are possible - please ask me about them. The switch changes between the MCW and ordinary CW modes.  The sidetone oscillator is activated for either type of Morse, with an optional audio output for feeding into an external amplifier, even when the RF parts are switched off for simple Morse audio demonstrations. The design includes a TR antenna relay and adjustable level muting for receivers where it is desirable to be able to hear a beat note from your own transmitter. It has socket inputs for a dynamic mic, with PTT switch, and a straight key. The RF output filter assumes a 50R load - real or dummy!
  • Halse and Hatch.  The emphasis in this phone singe sideband design is ease of construction. The Halse RX can be used on its own but together they form a single band 5 Watt SSB TCVR for any single band of 20, 40 or 80m. The superhet's IF is 9 MHz which gives coverage of the 20 and 80m bands with a single VFO band near 5 MHz; and by just changing the VFO inductor it can work near 2 MHz for the alternative 40m band. Starting at the aerial, the receiver has a double tuned RF filter, followed by the first mixer which is an SA602 having its own discrete IF amp prior to the IF filter which uses four crystals in a ladder formation. The second mixer is also an SA602 which includes the Carrier Insertion Oscillator and can work on either sideband by the addition of an inductor. The first audio stage uses a pair of BS170 MOSFETs driving the AF gain control, which is followed by the audio output stage able to drive a loud speaker or phones. The RX PCB is nearest the front panel in the photo below. You can add the Mini CW kit, the Mini AGC, and or a digital frequency readout - the three digit one is most appropriate. WB6DHW carries the UHFSDR board and kit, plus several add ons and accessories.

  • UHFSDR Transceiver. The UHFSDR is a Software DefinedTransceiver 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 Mixersare used to convert signals to and from base band. A receiver pre-amp (2dBnoise figure) and a transmit pre-amp(50mW max output) are provided as well as antenna switching plus provision for separate receive and transmit connections. There is a Yahoo Group for support.
