CHIRP can't make a radio do something that it doesn't support. The BTECH MURS-V1 support was developed from the BTECH GMRS-V1 support which was developed from the Baofeng UV-82 support. The UV-82 supports adjustment of squelch thresholds so that support was transferred to the GMRS-V1 and eventually to the MURS-V1. It was just assumed that the BTECH models supported this feature. Apparently they do not.

Thanks a bunch, I really appreciate the response.
The note from Katy at Baofeng was a little vague. “At this time the squelch limits cannot be adjusted” — What does “at this time” mean? That the feature may somehow be enabled in the future? How would they do that? In a new hardware release (the -V2?)? With a firmware update? Or with communication to Chirp developers to explain necessary changes to the driver for the MURS-V1?
Any of those are probably a long way off in the future, if they happen at all, so no point in holding my breath. Oh well. It was worth looking into.
Thanks again! —Bill
