Is there any problem trading out crystals for like manufacturer receivers. Ex: I have a 6ch jr rec. with a crystal that I want to take out and put to the jr 955s. Any probs.

Thanks in advance.

It's fine as long as both are single conversion or dual conversion. I am not familiar with JR's receivers.

A dual conversion crystal in a single conversion receiver (or vice versa) will not work. Also, stick to crystals of the same brand as the receiver, as you alread mentioned.

Thanks.. The receivers do not mention anything about conversion, but one is FM and the other is spcm. Does that matter.

I don't think so, but please don't trust me on this one - as I said, I'm not well versed about JR equipment.

I suggest you resubmit this question in the JR forum: http://www.rcuniverse.com/forumdispl...forumid=174&s=

I was just reading another thread, and it seems that the R945 and R940 are the only dual conversion receivers JR makes, and all others are single conversion. As far as I know, the encoding method (PPM / PCM) makes no difference to the crystal.

A quick range check after swapping the receiver crystal is always recommended.
