I have an ICOM 621-2-TR running conventional UHF in the business band. It transmits fine, but on receive it seems very insensitive. Even with the monitor button on, it only picks up very strong signals. I have tested the antenna (1/4gp) with and adapter to a HT and the antenna is fine.
My question is this: does the squelch setting (currently 90) affect the decoding of CTCSS? Will the unit break squelch if the signal is below the threshold but the correct CTCSS tone is present? Or will a high squelch setting lock receive out even if the unit hears the right tone?
I suspect I may have a hardware problem since the unit is being outperformed by 4 watt HTs. The setting is in an industrial facility, HT's can talk to one another everywhere but the 621 only hears transmissions from outside.
Thanks in advance for any help...
