There is a CW offset of 200Hz which cannot be lowered so my observations
are:
1. If I set the VFO A in PowerSDR at 14.310000Mhz and make a "Tune"
transmission I note that the actual measured freq is 14.310000Mhz on both
CWL and CWU- this makes sense to me.
2. If I keep the VFO A freq at the same 14.310000Mhz and select LSB and
make a "Tune" transmission my actual transmitted freq is 14.309800Mhz. The
200Hz offset comes in to the equation.
3. Ditto 2 above but select USB and my "Tune" transmitted freq is
14.310200Mhz. The same 200Hz CW offset comes in to the equation.
My QUESTION is what is the actual freq I am transmitting on in 2 & 3 above
when I use the LSB or USB mode but actually speak rather than select the
"Tune" button?? Of course I do not transmit voice on LSB at the above
mentioned freq!!
Thanks for any help as ever.
