I want to use my 3pjs 3-channel Tx radio with multiple boats/cars. I have one R113ip 3-channel 75 mhz receiver with a (blue sticker) channel 82 crystal that matches the one in the Tx.

I just ordered/received another R113ip rx, but it has a BLACK sticker ch. 82 crystal.
Both the black and blue crystals appear physically identical.
I bench tested the black Rx crystal, and it works.

Q #1: Is the blue labeled crystal defined as the "short" style?

Q #2: Is this black labeled crystal compatible with the blue sticker Tx crystal for actual use? Or do I need to get another blue ch. 82?
