No TX on Phone

[KJ5DTK]

Hey All,
Just built my (tr)uSDX last night (Low Bands) and I'm trying to get everything working. CW works well and seems pretty clean with good power and efficiency numbers on all bands. Ref freq has been tuned to a zero beat as well. But I'm having an issue with phone output (AM/FM/SSB).

My initial though was I probably put the mic in backwards. So I double checked that and it was correct...but flipped it just in case and still no output.

On SSB I get a "pop" on a receiving radio when I key up but nothing else.

When vox is enabled the transceiver quickly switches between Rx and Tx. Not sure if that is helpful or not.

I'm running the 2.00x firmware on rev 1.2 hardware. I'm not really sure where to start looking so any help is greatly appreciated!

Thank you,
Jared
