Mods I've done.

1. DDS vfo - i got one of the pre raduino ones.
2. Remove cap between pins 1 and 8 of the lm386 and replace with a switch so there is both cap and no cap options.
3. Additional power jack to feed in 24v to the power amp. Its on a switch so i can run it with 12 volts off one supply also.
4. Replace the cap in the bfo with a trimmer per recommendation of Peter VK3YE.
5. Replaced the volume/switch pot with a separate new pot and switch.
6. Put the upgrade raduino module in and converted it to use a rotary encoder.
7. Added the voltage readout to the display.

A couple of failed mods that I've undone. Relays to eliminate the PTT pop - didn't work. S meter on the raduino - too noisy.

Oh, and bigger heatsink when i did the higher voltage mod.

Regards?
