[TenTec] Squelch onn Omni VI

[Darrell W4CX]

I'm thinking about using some high-quality transverters (elecraft) for
VHF/UHF work using my Omni VI as 28Khz IF strip.  But I discovered that the
Omni's squelch only works on FM.  I couldn't bear listening to white noise
all the time waiting for the bands to open, and I'd rather not have to
switch to FM for monitoring.  Does anyone know of a way to enable squelch on
SSB/CW on the Omni VI?  Any thoughts on this approach?  73, Darrell W4CX
