A few things to check:

When you press the transmit-pressel, you should be able to clearly hear a relay click inside the PRC320. Does this happen?

If so, when in SSB/AM mode, do you hear any "sidetone" [your voice in the earpiece when you press transmit and speak into the mic] ??

If the relay's not changing-over you will not see much happening on transmit.
