Am I wrong in my understanding that one can "simply" swap crystals in the radio and "all should work"? I recently purchased a replacement receiver (Futaba) and I'm not getting any reception with my old crystal. Any information would be appreciated.
Ypu can up tpo a point swap crystals in the RECEIVER to chjange channels, tho a re-tune of a couple of coils is advised if you move too far from where it was originally set up.
The same IS true of a transmitter, except you are legally discouraged from doing it.
If you don't know what you are doing, take the rig into the LHS.
1) did you change transmitter frequency also? or just the new receiver? If you changed transmitter frequency, your transmitter may not be "hitting" on the right channel clearly enough for your receiver to read. You can do a search here for pages upon pages of arguments about changing transmitter frequency in the US by changing crystals without retuning, but anyway, Futaba and the FCC recommend you have it retuned.
2) do the 2 receivers use the same crystal TYPE? be sure you have the right crystal type, not a short crystal for a standard crystal application, single conversion in a dual conversion receiver, etc.
3) try purchasing a new crystal and try the new receiver. Still no reception?
hope this helps!

Hi AnnMarie! Maybe you could answer a question for me. I have a set of 72-7 Futaba crystals. Are these the 'short' single conversion crystals? My DC crystals all seem to be marked 72-10? Thanks!
