This is an arduino powered digital interface for ham radio. No more need so many cables, just USB to computer and audio in/out to radio. Instructions and code can be found here: //kb9rlw.blogspot.com/2016/08/cheap-and-easy-to-build-digital-modes.html

When 70MHz band opened for amateur radio use, i was disappointed because i had no radio for that band. After few years i found reasonable priced transceiver for 4m band. With this transverter i can operate on the 4m band with HF radio that has the 10 m band. It works the whole band,  70-72 MHz and any modes which is available in HF radio.

More than 10 years ago I found Anthony Good’s homepage. Then there was instructions to build pic-microprocessor based memory keyer which has every option i needed, or even could imagine. I built couple of them for my friends and for me, and it was in use until I found that he has new version made with arduino. Of course I built it too and it is excellent.

Here is few low quality (only vga quality cam in phones back then) pictures about original PIC-version.
