RE: Crystals for FMH P-2ch radio
Well after not getting any answer, I bought NIB FMH stadium truck. It came with a crystal set that resolved my mystery.
The radio takes a crystal at approximately half the receiver rx crystal. Here are 2 examples
CH8: TX=13.5125Mhz RX=26.570
CH10:TX=13.5625Mhz RX=26.670
As far as I know, no other radio works this way. All others take in the transmitter a freq. close to the RX with a slight shift.
Hope this helps others if they run into a problem with these radios.
