I built a cable to connect my Orion (via the Aux I/O connector) to my PK-232
tonight. My PK-232 includes the optional built-in "PSK" soundcard interface
which has worked fine on my Icoms. Even with the Aux input gain turned up to
100 (using software V1.372) and the computer output full-up, I can't get enough
transmit drive to generate any RF output. I can hear the PSK31 transmission
very faintly through the monitor circuit, but I can't increase the drive
enough. There's an adjustment on the PSK circuit card inside the PK-232, but
it's full-up also. The regular PK-232 TNC modes (RTTY, etc.) have plenty of
drive and I can get 100 watts output. The problem only occurs when the
soundcard portion is active. The Aux input is so low that I can't get the VOX
to activate even with the VOX set to the most sensitive setting. (The
soundcard receive is also pretty low, but I think it's probably good enough to
use).
I know the Orion can be used (for soundcard modes) without the interface, but
I'm wondering if anybody has any suggestions on this. Can I get more gain
going through the front-panel mic connector? Thanks...
