Hi Grant,

Yes. In version 1.372,  if you are transmitting in the AM mode and 
adjust the "TX Filter Bandwidth" control or the "LF Rolloff" (both under 
the "SSB" Menu), you can hear the effect both in the MON circuit as well 
as on an external receiver. I just tried it to be sure.

Can someone that still has an Orion with 1.372 or earlier software tell me
if the SSB high frequency cutoff varies the AM transmit frequency response
as heard through MON?

There's a note in the Orion II manual update that AM transmit is limited to
6 Khz bandwidth.  Not sure if this is a new development or was also the case
with the Orion, but there is no effect on transmit audio varying the SSB
high frequency cutoff.  And I just don't remember what the O's behavior was
in this regard -- seems to me it had an effect, but could be another memory
trick ...

Thanks ... Grant/NQ5T
