RE: Tx Rx crystal/freq mystery
i wish it were that simple. The new Tx the crystals came out of is a [link=http://www.futaba-rc.com/radios/futj40.html]4YF[/link] and it is FM.
Stick Jammer, don't worry. I did not violate any rules swapping the first crystals as the change applied to your rule #1. and no I haven't been hacking inside the radio either.
Anyway, I'm back where I started. Not knowing.
But thanks to all for the input.
