Re: No PTT

 

Do you have the 4.7K on the key line soldered properly?

Worst case you will need to replace the NANO. If you are experienced fine otherwise take some
help so as to not damage the raduino board when you remove the nano. I removed the nano
and left the pins on the Raduino so that it wont get damaged.

I should also say that the display lights up, saying "VFO A 7.150 MHz, it will not tune, although the encoder shows 5-0-5-0-5-0 at the pins as it is turned. Pressing the knob 'in' does nothing. The audio produces a hiss and the volume control works OK.
