Would I be talking out of turn here to make a request? Profuse apologies
if so and I'll go back to just observing, but this topic touches on
something I'd like to experiment with when I finally get my hands on an
HPSDR.<br><br>
I'd like to be able to use Cashmir as a "modulator" to plug a
signal directly into a receiver. Obviously an external attenuator would
do the job, but if there is a way to get the low level signal directly
from Cashmir that would be nice. Where I see this being useful is in the
remote receiver scenario where the operator would prefer to use his old
rig as the interface rather than a computer. If the rig has serial
control such as CAT, then these control signals could be transmitted to
the remote PC to move a filter (virtual/proxy receiver) over the Mercury
output or whatever. I haven't though too much about the TX side but it's
not hard to dream up scenarios.<br><br>
Another use for such a feature in Cashmir is where HPSDR is used as a
flexible RF signal generator, in which case perhaps an option for a
switchable output attenuator might be beneficial if there's
room.<br><br>
I'm back in my box now (c:<br><br>

Tx output could be brought up to say a 10w level with the new Mitubishi
