Default 4NEC2?

Consider a 2 tone signal at the 9MHz USB IF, comprising 900Hz and
1300Hz tones.

The components will be 9.0009 and 9.0013

Subtract the VFO at 5.5MHz:

9.0009 - 5.5 = 3.50009
9.0013 - 5.5 = 3.50013

Nothing has been inverted. The 80m signal is still upper sideband.

strips the crosspost - without a repeater, he's not going to answer you.





Try it the other way around and use a ssb generated at 5 mhz and the vfo
at 9 mhz. It is difficult for me to remember which was used for the vfo
and ssb generator.
