  1. Updates.
  2. The HamPiRadio is about complete, with a couple of constructors already building them to ensure the build instructions are up to scratch and can be successfully followed and radios built.
  3. A lot of work is currently under way to improve the web site (Thank you for the feedback friends, all friendly feedback welcome).
  4. The intention is to distribute kits of parts for each board as this will be easier for the constructor. More detail to follow…
  5. There are currently 7 sets of PCBs in stock and in the next couple of weeks these will be fully kitted up for distribution.
  6. The completely new Balanced Modulator, Product Detector and a mic compressor are employed and working well on the Radio Board
  7. A new version of the PA has been produced and tested, and is working better than expected, delivering up to 150W. It uses the RD01, RD16, RD100 lineup.
  8. The project has been working well for ages I have had quite a many QSOs across the world. Audio reports have all been excellent. See QRZ.com ZL3AX. More soon…

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.
