[Elecraft] Need to shift 8 pole 2.1 filter?

[Guy Olinger K2AV]

Oh, remote controlled...  That would be the app programmer's issue,
not Elecraft. TRX Manager does not appear to acknowledge any support
for Elecraft on their web page.  Sort of whatever works, fine,
whatever doesn't, too bad attitude, if they even care.  Just marginal
support for TenTec.

I believe you need to negotiate a feature with the programmer of TRX
Manager.  Like maybe supporting Elecraft outright?  You can program a
macro to set your preferred shift setting IF you can send a macro
string to the K3.  See the current K3 programmer's guide.
BW2100;IF1350;  if you want to start hearing at 300 Hz.

You want to base your choice of rigs on the 3rd party software, or
base your choice of 3rd party software on your rig?

If you attempt to solve this by setting the filter calibration offset
in the K3 utility, it will work OK for one sideband, but turn the
other into Donald Duck.  Don't go there. That is only establishing for
the rig where the crystal's center frequency actually is, so it can
respond to offsetting commands in the firmware.

73, Guy.
