Thanks, Scott. I wasn't sure of which radio we're talking about. Had I
known it was a Motorola, I would have consulted with my Motorola guru here in
SD when I ran into that 21.4 IF...

So if she's converting a commercial band radio to ham band, she'll need to
know which frequency range the radio's in? As in 450 to 460 vs 460 to
0MHz.
