I figured that it probably had the crystal changed. While the bigger transmitters can only be recrystaled within a relatively small range (1/3 – 1/2 the band) because of the filters on the output of the amplifier, I’d be somewhat wary, but I *think* that’s not an issue with the AM-5. Still, better safe than sorry, so best that you get one already as close as possible to your frequency to avoid problems. I notice that one’s sold now (to you? CONGRATULATIONS!) and he’s got an another AM-30 up again.
