Radio Kit Guide

W2NDG's RadioKitGuide.com UPDATED 6/16/2021

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.

QRPGuys AFP-FSK Digital Transceiver III

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: QRPguy.com 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.

A list of classic and radio-oriented surplus outlets online

Revised June 2021:  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.  There are several new kits worth checking out, at QRPguys.com, Four State QRP, and Walford.

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

-Borden Radio Company.  http://www.xtalman.com/kits.html.  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.

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.  https://www.mikeselectronicparts.com/   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). http://www.minikits.com.au/ 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.  https://www.multus-sdr.com/  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.
  •Open Source firmware.
  •Firmware Field Updates via on board USB bootloader.

  With these additional features:

  • All band. The Proficio covers all bands from 160M to 10M.
  • Enhanced receive. A RF amplifier is now in the RF front end that provides about 19db of gain at      10M and tapers down to about 0db at 160M
  • Receive Band Pass Filters for all band groupings (160M,80M,40M-60M,20M-30M,15M-          17M,12M-10M)
  • The same BPFs are used in conjunction with Low Pass Filters in the transmit path to provide a clean output.
  • 5W Class A PA. Clean output of 5W on all bands (slightly less on 160M and 10M).
  • Real CW. Supports zero latency CW. Software generated CW is not required.


-Nightfire Electronics.  http://vakits.com/catalog/ham-radio-kits.   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.

• QRPGuys AFP-FSK Digital Transceiver III.  The new QRPGuys Digital Transceiver III kit for 160m-10m is a low cost, multi-band, multi-digital mode, 5 watt transceiver kit, with VFO and plug-in module kits supplied for 40/30/20m. The v. III version debuts a novel firmware scheme for our Si5351A/MS5351M VFO which allows a move away from DSB transmission to SSB, by a new process we are calling AFP-FSK (Audio Frequency Processed-FSK). The SSB transmitted signal is generated by a unique process of measuring the input audio frequencies, then through software, producing the RF frequencies (pure FSK, not AFSK) directly by the VFO, eliminating the need for any mixing which creates unwanted sidebands. This innovative firmware and related hardware design changes by Kazuhisa “Kazu” Terasaki (AG6NS) and Steve Weber (KD1JV), allow ~5W signal on bands from 160m thru 10m for FT8, FT4, JS8CALL, WSPR, and RTTY modes. Though effective sensitivity is somewhat dependent on sound board quality and can pull signals out of noise, 0.1uV on the lower frequency bands and slightly less sensitive on the higher frequency bands is typical. The board is the same size as earlier versions, (3.0″ x 3.12″), and all the components are included for the transceiver, VFO, and band module kits for 40/30/20m. Bare module boards are available for additional bands. Each band module has automatic sensing to set the VFO to the appropriate band at start up.
• QRPGuys Multi-DC 10/12/15m CW Transceiver.  With the openings recently on 10 meters, it reminds us of the days for DX potential on that band with low power and smaller antennas. The absence of many budget kits for this end of the HF spectrum led us to approach Steve Weber (KD1JV) for a low cost kit design.  Steve then designed the Multi-DC CW Transceiver offering a three band transceiver that is optimized for 15m through 10m. Supplied are three switchable fundamental crystals of 21.060, 24.906, and 28.060 MHz for the QRP calling frequencies on 15, 12, and 10m, with RIT for ~8 kHz bandspread. The power output is 4-5W on 10/12m and ~3W on 15m at 13.8V. For less power, 1.5-2W, decrease the supply voltage to 8.0V. Receiver sensitivity, MDS ~0.1 uV on 15m, ~0.2uV on 12m, and ~0.5uV on 10m. Included, is an onboard header for connecting our optional Si5351A/MS5351M PLL VFO for full band coverage and RIT on all three of the bands, enabling you to listen to SSB stations in the phone segment of the bands, and general coverage SWBC stations outside the ham bands.  Built into the transceiver is Steve’s popular ATtiny45 SKC keyer with adjustable speed from 5-30 WPM, two programmable memories of 60 characters, straight key mode, and beacon mode if starting your own 10m propagation beacon is desired. All the controls are on the top, and I/O connections are out the back of the pcb for easy mounting. The input power of 8.0 to 13.8VDC is via a standard 5.5mm x 2.1mm coaxial jack. Audio output and paddle/key connections are standard 3.5mm jacks. The antenna connection via a board mounted female BNC connector is standard. Rx current consumption is a low 15 ma without the VFO, and 45 ma with it. Tx current consumption is 850 ma max. at 13.8V. Weight is 2.4oz. (68gm.)
• COMING SOON: QRPGuys Pacificon DSB/CW Transceiver Kit.  The QRPGuys Pacificon is a low cost 40m DSB/CW qrp transceiver. It is a Steve Weber (KD1JV) design, based on a project for the Pacificon 2020 QRP forum buildathon, and we are offering it as a pcb project and make your own case, or you can add the optional chassis, and/or SKC keyer kit. This transceiver uses a Si5351A PLL clock generator controlled VFO, single chip Atmega328P µP for control, a five digit LED frequency readout to 10Hz resolution, with rotary encoder tuning. It features a CW output on 40m of ~5W and ~2.5W PEP on DSB. A direct conversion receiver with RIT is utilized, switchable lowpass audio filter, multiple tuning rates, also with 500 KHz-30MHz general coverage reception, disabling the transmitter outside the ham bands. All the components are supplied, including the Si5351A chip, the only SMD component, all others are thru hole. The DSB voice mode is designed to use an inexpensive (not supplied) single plug Baofeng UV3R, (not UV3R+), speaker/microphone, available on eBay for ~$5-$10. Antenna connection is BNC female, 12-14V power is via a standard 5.5mm x 2.1mm coaxial jack, mic./speaker connection is a 3.5mm 4 pole jack, and external speaker connection is a 3.5mm stereo jack. Power requirements for TX are 650mA @12-13.8V, ~40mA RX. It is small, lightweight, and with the optional  4.25″w x 3.40″d x 1.12″h (108mm x 86mm x 28mm) chassis, total weight ~3.5 oz. (100gm). On a scale of 1 to 5, 5 being the most difficult, this is rated as a 3-4. The normal tools required are a soldering iron with a small tip, rosin core solder, small side cutters, and small phillips screwdriver. Allow an evening or two to build, depending on your experience. Steve’s Arduino Sketch for the Pacificon is in the Misc. Files section.

• Bramwell Regenerative Receiver.  a simple Regenerative Tuned Radio Frequency (Regen TRF) receiver design that is the modern equivalent of the sort of receiver that was used in the early days of radio communication.  It is suitable for group building projects run by radio clubs and as an introduction to short wave radio. The technique has very good performance for such a fundamentally simple circuit. It has two bands, primarily for amateur radio reception – the 40m band with its nearby broadcast stations, and the 80m amateur band. They use the same inductor which is adjusted for the desired part of the 40m band, and then the slide switch adds extra capacitance (with the trimmer) for the 80m band. Because it is a Regen TRF, it can be used for the powerful AM broadcast stations near 7 MHz as well as the common amateur modes of CW (for Morse code) and SSB (for phone) which are used on both bands. It has three main controls – the Main tuning with the large knob, the audio gain control (AFG) on the left and the very smooth Regeneration control on the right. There are also two preset controls for the RF gain and a master ‘oscillation’ control – neither of which need frequent adjustment. It uses three junction type field effect transistors in the RF section; these are arranged as an RF amp, the Regen stage and a buffer stage to drive the strong, but sensitive, full wave diode detector that feeds the integrated circuit output audio amplifier which can drive a LS or modern stereo 32R phones. This combination of controls provides excellent control over the receiver’s operation to suit radio conditions. There is a power on/off switch for the 9v PP3 battery (not supplied). The price is £24

• The Ivel Receiver.  This is a direct conversion receiver for any single band 20 to 80m using the classic combination of an SA602 mixer chip followed by audio stages with filtering for phone and CW; and finally an audio power amplifier output stage, which can drives phones or a small loud speaker. It is normally built in the small upright format which is easy to use and ‘calibrate’ with a vertical front panel. The PCB is single sided to keep things easy to locate the correct holes for parts and for ease of soldering. The photo above shows how simple it is! The RX design is suitable for serious contacts and incorporates several features like twin tuned RF bandpass filters and an audio filter for CW, that would normally belong to a more elaborate rig; for tuning, it has both main Tuning by a PolyVaricon capacitor, as well as a Fine control so that resolving SSB becomes much easier. The rig’s product detector uses the SA602 mixer/oscillator chip but with an external Variable Frequency Oscillator using a discrete JFET to provide better stability than is possible with simpler designs using an oscillator in the SA602. The mixer chip incorporates a balanced Gilbert cell transistor arrangement for good rejection of unwanted signals. The mixer is followed by an audio pre-amplifier, using one section of a TL072 dual op-amp with a bandwidth suitable for normal phone (SSB or DSB) contacts; the other section of the TL072 is a second order CW filter for Morse. This has a peaked low pass response with its maximum at about 725 Hz and sharp attenuation for high frequency signals. This suits the typical CW beat note pitch that many operators like to use in the 500 – 800 Hz band. The CW filter is selected by a front panel switch which feeds the front panel AFG control and then the LM380-8 output power amplifier for phones or a speaker. Adding a transmitter (Ilford for CW or the Ilton for DSB phone) is relatively easy but does take the project into the Intermediate category! Start with the receiver alone and then add the transmitter later if you wish. If you are unclear which band is best to build it for, the 40m band often a good compromise with signals from UK and European stations. Price is £27

•  The Bat Ultrasonic TCVR.  The Bat transceiver is a simple electronic construction project using amateur radio techniques for two way communication – it is for individuals or clubs, schools, cadet forces, scout groups, etc. Because it uses ultrasonic transducers working at 40KHz, it does NOT need any special licence. Two Bats can communicate over 50 metres or more with messages sent in Morse code, or a single Bat can be used as a Morse practice aid when teaching or demonstrating Morse code to constructor groups. The transceiver can be split into separate receiver and transmitter sections which may appeal individual builders. The price is £20.

• The Ivel plus Ilford CW TX.  The Ilford allows you to send Morse code. It is normally coupled to a simple receiver like the Ivel receiver described on the Simple page. The Ilford transmitter can work on any one of the 20 to 80m bands and is ‘crystal’ controlled – this means that it uses either a crystal or a ceramic resonator to determine the transmitted frequency. For 80m, there is a suitable 3.58 MHz resonator whose operating frequency can be pulled down by a tuning capacitor to give a tuning range of typically a few 10s of KHz in the CW section of the band. Unfortunately, higher frequency resonators are not sufficiently stable and cannot be used above 80m, so you have to use an actual crystal for 20, 30 or 40m – the consequence is that the tuning range on these bands is very limited – a KHz or so! This means that 80m is often a good band to experiment and learn CW skills. The transmitter produces 1.5W of RF using a 13.8 volt supply and includes an output low pass filter to get rid of unwanted harmonics. It also includes a transmit receive relay for switching of your aerial between RX and TX, this is activated automatically when you press the key and has a delay before reverting to reception to cater for the gaps between Morse characters. Pressing the key also activates the RX muting electronic switch which prevents unwanted crashing sounds from the RX when transmitting, while still allowing the keyed 725 Hz sidetone oscillator to run and produce audio output through the RX’s audio output amplifier. For 80m, the ceramic resonator can alternatively be fitted in the Ivel RX allowing transceiver operation where TX and RX operate on effectively the same frequency with single knob main tuning! In fact, the RX has to be tuned very slightly off (by the RX’s Fine control) in order to create a beat note but this offset is automatically removed by the Ilford when actually transmitting. This arrangement is a little more electrically complicated than separate RX and TX, but it does make operation very much easier! The kits in the picture above are wired this way for 80m. The standard Ilford kit includes the 3.58 MHz resonator but if you want crystals for the higher bands you need to tell me what is wanted. With a crystal in the Ilford for the higher bands, the tuning of the Ivel and Ilford are no longer linked and they have to be tuned and operated as ‘seperates’; so please ask me about crystals and adding a trimmer to the Ilford when contemplating this form of separate tuning and I will advise the costs. The standard Ilford kit costs £18. If ordered together, the Ivel and Ilford are discounted to £43.

• The Ilton DSB Transmitter.  This is a double sideband phone transmitter intended to go with the Ivel RX. Double sideband is much simpler and cheaper to produce than SSB and it is entirely compatible with stations using SSB – either upper or lower sideband. They wont know you are using DSB until you tell them! Much like the Ilford above, the Ilton needs to be crystal controlled except on 80m where there is a suitable 3.69 MHz resonator, which allows transceive operation with the Ivel on 80m. For the higher bands, they have to be tuned independently. Please ask me about these higher bands. The transmitter is mounted just behind the Ivel RX (see photo below) with links to the RX for muting when transmitting. The Ilton’s speech amplifier is designed for dynamic microphones and uses BS170 MOSFETs driving an SA602 modulator to produce the DSB signal; this is amplified using a high speed op-amp driving the IRF510 output stage (with heatsink) which is followed by low pass filters and the aerial change over relay. Peak output is about 1.5W when using 13.8v supplies. Should be just the job for across town nattering! The price for the Ilton is £24, If ordered together, the Ivel and Ilton are discounted to £49

• The Somer.  This is a new small CW TCVR for any single band 20 to 80m. It has a new LO scheme using multiplication up and division down from the VFO to avoid chirp without using a crystal or ceramic resonator! So goodbye to rockbound transmitters! The arrangement can provide whole band coverage but this is seldom actually desired to keep the Main tuning rate reasonable. The RX is direct conversion with a PolyVaricon for the main tuning and a voltage controlled diode for the Fine tuning and beat note offset; the latter being automatically cancelled when you go to transmit. The RX is direct conversion using a double tuned RF filter feeding into a SA602 mixer, with a conventional audio pre-amp, humped low pass CW filter and main audio output for phones or a small loud speaker. For transmission, the LO chain 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). 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 photo above is the 20m prototype Somer; two kind early builders have now helped prove the rig and the instructions! The main differences between the Somer when compared to the Ivel/Ilford combination is that it is half the size, with VFO coverage for any one of its bands and with full break in operation. The price is £52.

• The Ham RX and Hale TX.  The Ham RX is a superhet which means that only one sideband is heard – this is particularly relevant for CW when compared to simpler RXs which hear both sidebands: it is also highly desirable for SSB phone reception and essential when the RX is used to drive the Hale SSB or CW transmitter. The Ham has a 10 MHz Intermediate Frequency which makes it a little easier for one set of parts to cover the relevant small section of the overall 2.8 to 6.5 MHz range for any one of 20, 40 or 80m bands. The receiver comprises a double tuned RF bandpass filter feeding the first SA602 mixer with a simple output amplifier, feeding into a four crystal IF filter, and then the second SA602 mixer (with carrier insertion oscillator) acting as a product detector. The audio pre-amp uses one half of a low noise TL072 op-amp with its second amplifier providing a switch selectable third order CW filter. Then follows an AGC stage, using both sections of another TL072, which feeds the AFG control and the output audio power amplifier. For transmission, two relays (supplied with TX) reverse the signal flow through the RX’s mixers and IF strip to eject the low level RF out of the RX antenna terminal, but for reception without the TX, there are small PCB links across the normally closed relay contacts. The first mixer is additive on 20m but subtractive on 40 and 80m, so there is an extra CIO coil for 40/80m to provide the normally used sideband for all bands. Compared to earlier designs, this RX now includes a good CW filter as well as AGC all on the main PCB! The RX price is £50.  
• For the Hale, tracks are cut in the RX so that two relays can be fitted there to reverse the signal flow in the IF strip and both mixers, which together with the TX relays then activates transmitter stages. The RF amplifier chain is linear for SSB signals, or the keyed audio tone for CW. A TL072 low noise op-amp is used for the microphone speech amp and for mixing in the CW sidetone oscillator output when that is activated. These drive the RX’s second CIO mixer to generate DSB which is filtered by the IF filter to remove the unwanted sideband before that is then changed to band frequency in the RX’s first mixer, and then the through the RX’s RF bandpass filter so that it ejects low level RF out of its antenna terminal! The first TX RF stage is a grounded gate RF amp with Drive preset, followed by the main RF amplifier that drives the output IRF510 power stage (with large upright heatsink) and the low pass harmonic filter. The Hale provides a Maximum output of 5W nominally on a 13.8v supply for both CW and SSB but can be used with care on higher voltages for increased output. Control is by the PTT switch of your microphone (dynamic type) for SSB or with semi break-in operation for CW. The control circuits mute the RX via the AGC stage. You should not need specialist test gear to set these kits up pretty well if you have a general coverage RX, multi-meter and the normal RF accessories of a power indicator, 50 Ohm dummy load and Aerial Matching Unit. A scope and two tone oscillator are desirable but not mandatory with a little patience!  The TX price if ordered subsequently on its own is £42 but if ordered with the Ham, the pair are discounted to £85.
• The Queenie, Kingston and Phaser.  Together they form an advanced CW TCVR for any single band of 20, 40 or 80m capable of single sideband CW reception if the optional Phaser kit has also been added. The Queenie RX is direct conversion with a strong product detector using 4066 electronic switches instead of the often used SA602. The line up has the usual double tuned RF bandpass filter, followed by an RF amplifier whose gain is controlled by a switch. This drives two electronic switches for the product detector, (with the unused pair available for the Phaser kit extra channel). These switches only limit when signals get near a few volts of RF so the RX is less liable to BCI which is really helpful dealing with the adjacent broadcast stations! They are followed by a grounded base low noise first AF stage, then an audio op-amp and the switch selectable 3rd order humped CW filter whose peak is nominally at 725 Hz. The AFG pot follows with audio output for phones or LS. The product detector switches are driven by anti-phase square waves at band frequency; when the RX is used alone, these are generated at band frequency by the VFO which has a PolyVaricon for Main tuning and a potentiometer for Fine tuning and offset cancellation. With the Kingston fitted, the VFO instead always runs near 4.67 MHz, which is then squared up, and tripled by extracting the third harmonic for 20m, with division digitally by 2 or 4 if required for 40 or 80m, which then drives both RX and TX.  Queenie RX only – £42, Kingston TX (if ordered later) – £25, if Queenie and Kingston ordered together – discounted to £64, Phaser kit – £18. If Queenie, Kingston and Phaser all ordered together – discounted to £80
