Linton 3260, no receive

[thoward]

Afternoon

I have 12x Linton LT-3260s. They have been put away since about 2010 - they were bought around 2007 and have seen relatively little use (couple of weekends).

What I've found is that 8 have developed a problem - all 12 will transmit, but 8 of the 12 will not receive.

Between two good radios I can get RX and TX, with the bad radios one of the good 4 will receive, so it seems the TX on them is still working, but none of the 8 will receive. It doesn't seem to matter which radio is transmitting - the 8 will not receive regardless of which of the 12 is transmitting (good or bad.)

I don't think it's a squelch or CTCSS issue, as if I turn the monitor function on on one of the radios which won't receive I don't hear anything - just static the whole time - whereas if it was a squelch or tone issue I assume monitor would over-ride this.

I've reprogrammed all 12 so I don't think it's a frequency issue (some receiving on one frequency or another)

Any suggestions as to what to test welcome.

Listening to the monitor function on the radios, it would appear the the radios are receiving - but the talk into a good transmitting radio is heard on top of the static, so the static doesn't mute when a good radio signal is received. So no receive light, but with monitor I can hear the signal, but it isn't clean
