What is happening is your sound card in your pc is causing feedback. This
happens on a lot of soundcardsif they work duplex ie. If you speak in the
mic on it and can hear your voice through the speakers The best way I have
found is to use a relay to act as a type of cross over switch between the
two ( feed to mic on feed from speakers off ) that way you can use the com
port of your PC for the recorded CQ's using the com port for the ptt
I know I haqvn't spelt it out in techie speak but I am sure you get the idea

Subject: [WriteLog] Problem with Voice TX with Ft-920
Hi!
I am quite new with WL and uses a Yeasu FT-920.
I wired it thru a Exodin interface to Patch in and AF out as recomended.
If I am in SSB mode and press in my vox my tranciever will start
transmitting, without me saying nothing????? And even if my mic is not
connected???
This problem occurs even if WL is not started?
Also, If I connect my microphone to the computer or mick input on the ft-920
and "yell" during this automatic transmitt I get no modulation???
Please help!
