Build your own LF / HF / VHF Transceiver.
Latest News
*** 8 August 2024 ***
- The concept for the HamPiRadio is currently being rethought. The complete design will soon be Open-Sourced and available on this website. The designs will then be downloadable and available for private use by constructors and designers and groups alike on a non profit basis.
- Many parts will still be sold from here on a non profit making basis, or constructors can buy them themselves. This will include PCBs with most parts smd fitted, limited kits for the through-hole parts, ferrite and specially designed 10mm TOKO type transformers.
- The final hurdle! There are just two small but important ongoing issues on the Radio Board, both RF in nature. If you are good with RF design, like a challenge, and would like to contribute – please do contact me. They are 2 small but interesting challenges.
- The project has been working well for ages I have had quite a few QSOs already. See QRZ.com ZL3AX
Welcome:
The HamPi16 is a 16 band LF/HF/VHF Amateur Radio project for the home constructor. In initial project will receive and transmit (CW & SSB) works on all HF bands (160m to 10m 100W) plus the 50mHz and 70mHz bands (6m & 4M Lower power). On receive it also works on the two LF bands 160 & 475 kHz and VHF 144mHz. In the future the LF and VHF RF Amplifiers and switching can be developed in a separate housing(s). The emphasis on the initial project has been quality basics of the receiver and transmitter. This is a project you are encouraged to get involved with for ongoing developments and improvement.
The concept demanded that this transceiver be easy to use, with the important functions right there on the front panel. When working that sought after and rare DX it is frustrating to have to wade through menus to find the right filter, or RIT, or notch filter, or adjust the gain of the various receiver stages to reduce QRM. The HamPiRadio has adopted the controls really needed instantly in the form of a real knob, or a single press keypad button. The photos here will say more than words… There are also some other handy features to be seen on the Features page.
Below are two short videos of comparisons on-air (These were done a while ago before LCD display was replaced with a TFT display). The first video is comparing an Issue 1.0 HamPiRadio with a Yaesu FT902DM which is well known for its great receiver. The second is of HamPiRadio and the ICOM IC-7300. As you can see the HamPiRadio outperforms the FT_902DM, and is ever bit as good as the IC-7300, and may even have the edge. For more comprehensive technical comparisons see the Test Results page.
