All right, thanks for the replies. So, maybe there is a terminology issue here. It seems that some of you are saying that 72.89 and 72.97 are the same _band_, or would RC-ers call it the same _frequency_? (That is, "The 72 MHz crystals").
Or are 72.89 and 72.97 considered different frequencies? They are, then, a matched set?
The Towerhobbies crystal set can be seen here:

I didn't think the -7 or -12 were referring to TX or RX, since many sets have -1, -10, etc. I thought the 72-x were a subdivision of the 72MHz band. Is this not true?
Post the model numbers of your Tx and Rx, along with any designations on the crystals you have. Futaba has several different types of receiver and transmitter crystals. It's important to get ones that match your model. Also look at your Tx for a channel number or frequency designation. If the original channel number of the transmitter doesn't match the crystal that's in it you really should send it in to get it tuned to the frequency you plan to use.
