Assuming the AA5 converted to the HF receiver still uses a 455 KHz IF, you'll be mixing the RX VFO with 455KHz to generate the TX frequency. You'll have to be careful of 455KHz harmonics (the 4th is at 1820 KHz) and other mixing products that could fall inside the band, or close enough to it so that they are not attenuated sufficiently prior to being transmitted.
Mixing the TX VFO (on the TX frequency or a sub-harmonic thereof) 455KHz higher for injection at the RX doesn't work because the TX VFO is right on the RX frequency, and that will be all you'll hear! 73, -Larry/NE1S From: "Theosleaper" <[EMAIL PROTECTED]> > I like this idea.
