Hi All
The (tr)usdx will transmit CW OK, but not SSB or FT8.
When in SSB or FT8 the display shows T but no audio is transmitted.
I am running off 5V and using a cable for FT8 or internal mic for SSB
Voltages around audio input to the 328 are...........
PB4_MISO = 2.6V
AVCC = 4.6V
AREF = 1V
PC2_ADC2 = 0.5V
Could there be a dry joint an still show correct voltages?
I have tried the noise gate at zero, I am using the latest software and have reset the radio 3 times, the mic is fitted the correct way round all with no success.
I have a test meter but no scope
Ideas welcome

Re: No audio TX on SSB or FT8, OK on CW
The answer..........
I had not been using a power meter and in SSB & FT8 there was in fact RF output
I was using the on board power meter which does not work in SSB & FT8
Duh!

Re: No audio TX on SSB or FT8, OK on CW
Thanks for this post! I just went through a similar problem, and finally posted a message looking for help, and then I ran across your post and solution. I immediately connected a power meter and tried again - problem solved! I had been looking at the radio display instead of looking at a power meter!
