Hi, I'm trying to figure out what 40MHz frequencies match to the channel number. E.g. Channel 79 is 40.XXX MHz.
My JR XR3 came with channel 79 and I've since bought JR channel 81 crystals. The transmitter crystal has 40.790 stamped on it for chan 79 and the chan 81 has 40.810. However, the recevier crystal for chan 79 has 40.335 stamped on it, and the receiver crystal for 81 has 40.355 on it.
I found a list of 40 MHz frequencies at KO-Propo's UK web site (http://www.kopropo.co.uk) but it doesn't have any of the frequencies I've listed above.
The reason I need to know this is for frequency conflict resolution at my track. Last weekend at my track some new guys turned up with 40M radios. Up until this point I was the only one using 40M. Their's were KO, but they only listed the frequencey not the channel. So we had to resort to more primitive methods of figuring out if our radios clashed (like turning both cars on at once to see if one radio would affect both).
Anyone know, or maybe of a web site ?
Thanks, FP.
