I have an NHRC-7 that had a DOA CSQ LED on port one brand new out of the box... Only lasts about 6 months between LEDs - something in the circuit is blowing through the current reduction and literally making the LED cook...
For now, we've just disabled the LEDs all together - even though it's a through hole component, it still sucks to have to replace it on the mountain top... The Power, PTT, CTCSS, and CSQ LEDs for port 2, along with the CTCSS and PTT LEDs for port 1, and all 3 of the DTMF decode LEDs, have yet to have a single issue - just the CSQ on port 1.
