2018 ~ The Year of SSB Transceivers

Something for the SDR Crowd!
You too can build your own SDR Transceiver!

Second Generation Main Board

The board above is a second generation board and contains the two ADE-1 Detectors and the Modem coupling transformers, the divide by four 74AC74 and to be installed is the band pass filter. If you look close you can see the ferrite core balun used to split the signals going into the two detectors. This is a deliberate attempt at isolating signals and keeping things neat and tidy. I am thinking about a separate enclosure just for this board. Later today I will install the bandpass filter with the intent that it may be used at 9 MHz with a possibility of a different front end. You will have to stay tuned for this.
How about using the SDR on WSPR?

While I can claim I built this rig and added several modifications, by and large the credit goes to Charlie Morris ZL2CTM for his design and software development. You can follow ZL2CTM on YouTube and he has many videos and tutorials!
The bottom line…

Boat Anchor to Silk Purse.

Start looking for some old boat anchors as they offer possibilities for upgrading to modern radios.  Right now I am personally trying to locate a reasonable condition, reasonably priced Heathkit Hot Water HW-32 or HW-32A. The plan --Color TFT/Arduino/Si5351 upgrade so it will have full band coverage and offer switchable sidebands. Possibly even CW with the 3rd Clock. Email me at  if you have one of these rigs hiding in your garage and are looking for a new home for this jewel of the 1960's. Remember reasonable condition and low cost. If I can do this to a HW-101 just think what a HW-32 or 32A would look like.
