There is a red dot on the inside of the RX to denote high and low also. I have it written down someplace in my shop if that denotes high or low but off the top of my head I can't recall what is what?? The dot should be on the side where the crystal goes. Perhaps someone here knows without me digging through my papers and will post up?
Gene,
If there is a red dot present then the receiver is high band. No dot and it's low band.
