I have 2 BTL-301's with the same problem. There is no squelch. There is noise leaving the squelch control. I have not traced it any farther. I can not find my service manual for BTL301. Is the circuit like the BTH201? What parts cause the most trouble?
I found the service manual. I have not found the problem. Receive sensitivity is good; however, noise with no signal is low at TP A. I verified this with another good radio. It is about 1/2 level of good radio. TP A is output of IF detector chip. I have changed IF chip, noise rectifier transistor, ceramic filter, and electrolytic capacitor in circuit. Last time I had a problem like this with a Maxar, it was leakage in the circuit board. I am running out of ideas.
