How do you find out what channel your on because i have no clue and also do you have to buy a reciver that matches

If you look at the rear of your transmitter, there should be a small round silver sticker that has the channel number and frequency on it, or you can pull the crystal and it will have a tag with the frequency as well as the channel. (channel 50, for instance, is 72.790 MHz)
AM Tx must use AM Rx, and Fm with FM. PCM is a type of FM, both Tx and Rx must be PCM.

Yes, your receiver has to match the frequency, the receiver crystal will also have a tag with the channel/freq. on it..............

UNLESS-- you have a radio system with a frequency synthesizer, which allows you to select a desired freq. The Tx and Rx still have to match.......

OR-- you have one of the new DSSS (Spread Spectrum) systems, which is on a totally different band than 72MHz FM. The Tx and Rx are matched to each other, and only work with each other, on any available frequency in the 2.3GHz band.

To find the channel with a little simple math, take the 72.790, forget the 72 which leaves you with .790 add .21 then divide by 2. .790+.21=1.00/2= 50.

What is the model of your radio?
