Re: No PTT

Hi John,

Current consumption is a constant 160 mA, so it is not in 'Transmit'. Tx current was about 460 mA.?

Hello Geoff,

With no key pressed on the CW input your voltage is logical.

But earlier on you mentioned 1Volt on the PTT and that is not normal.

If your Raduino was to see a low PTT logic it would switch to USB or LSB transmit and that would explain the absence of tuning and CW keying.

So I would check/desolder that line first.
