Transverter offset

Ross Biggar
I need to put in an offset for 1296EME into the transmitted signal.
My question is, I am using VFO B in a split frequency, ie transmitting on B and receiving on A.
Can I put the offset into VFO B or does the transverter offset only apply to VFO A. I feel the manual is not
clear on this point.
 
Regards

If you program an offset in CONFIG:XV1-9, it applies to whatever VFO you are using.

If by offest you mean the transverter offset (config: XVxOF) it applies to
both VFOs.

This brings up another interesting K3 Xverter observation from the VHF
contest a few weeks ago

config: XVx RF allows only 3 digits of MHz, quite reasonably, because thats
all the display can show. However it is these 3 digits of MHz that the RS232
will report.

Example on 1296 with Xv4 RF set to 296 rs232 reports 296.100, which is not
recognised by the logging program as its not a ham band.

I have already asked elecraft for a feature request to allow 5 digits of MHz
to be entered in Config:XVx RF and be reported by rs232 but (as now) only
show 3 digits of MHz on the display

Currently the work around (on 1296) is to tell the logging program and the
F1EHN tracking software (for auto doppler correction)  i am using a xverter
with a 1 GHz local oscillator  so 296 appears as 1296 again

Re: Transverter offset

AD6XY
Sorry this is an old thread. Is there any particular reason why the frequency error offset is limited to +-9.99kHz? My 10GHz transverter has attained LO stability at 25kHz off its nominal figure and I can't correct for this.

10kHz sounds like at lot on 2m or even 23cms but on 10 GHz its barely 1ppm.
