Splinter Transceiver from BreadboardRadio.com

Kit building appears to be on the rise again.  With so many people talking about it lately I attempted to research sources for kits, only to find out that there wasn’t a single-source 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 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 trasmitters, transceivers, and some receivers here.  Some accessories are mentioned in the source descriptions.

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 2/26/2013 Added Kit Radio Company, GQRP Club, Kenneke Comm., Walford Electronics, Kanga UK, QRP Project, Kits by EA3GCY, and OZ QRP

Enjoy, and feel free to add any corrections, or additions in the comments.  The list can always be found at RadioKitGuide.com–Neil W2NDG

The pads are actually etched on the board (like surface mount), and the interconnections between them are PCB tracks, hidden under the solder masking. No “through hole” connections are made, although “through hole” components are used. Available in 40 Meter version, more to follow.  The kit includes all components, the complete case, and knob.  £42.00 + S&H
• GQRP Club “Limerick Sudden” Receiver Kit.  Built around two integrated circuit chips; the SA602 and the LM386. Both lend themselves to simple receiver construction.  Uses same method of construction as above, and is available in 160m, 80m, 40m, 30m, or 20m versions.  Includes all components, complete case, and 9V battery.  £42.00 + S&H

• Pixie II CW Transceiver Kit.  A very simple and inexpensive transceiver kit that can be built to operate on any one band from 10 to 160 Meters.  Several crystals also available as well as a 7MHz VFO kit, a connector kit, and more.  $29.95 including shipping in the USA.

-Walford Electronics http://www.users.globalnet.co.uk/~walfor/.  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 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 a heatsink 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
• 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

The audio gain control, RF attenuator and tuning control are mounted on the PCB. The kit is supplied with Toko 10K coils, but the board can also be used with toroidal coils if Toko coils become obsolete. The PCB has a solder mask and the component positions are marked in white screen printing. There is provision on the board for a switched-bandwidth audio filter and a mute circuit with adjustable sidetone bypass.  £28.50 + S&H
