Quick UHF radio/repeater question- clicking sounds?
I have at work an old Standard RP70 desktop repeater and a bunch of handheld radios. All of a sudden we get constant clicking sounds and some people say they cant transmit far anymore.
As a side note: we just moved stuff around and some cables may have been undone and then put back. The only cables that COULD be accidentally reverses are the low pass and high pass- whatever that means?? Just a theory so far. What are these? If i switch them and its not the original problem will I fry the repeater??

This very thing happened today at 4pm.

Was trying to connect my laptop, it was a loud clicking

uninterupted. i quickly shut it down. scared the whiz out

of me, never happened before. i have heard the clicking

sound somewhere else, just can't put a finger on it.

Did the problem start after the stuff was moved around?

Is there anything near by now, that is new which could interfere with the equipment.

Have you even tried the radios without the repeater and seen what happens?

the above suggests you are utterly clueless
yes you will likely fry it if the SWR is high for the xmitter

undo every single cable connector and carefully inspect and clean all connector mating surfaces with appropriate contact cleaner

look for any loose imperfect connections, discard or repair where necessary.


it is likely you're having passive intermodulation problems and could even be generating interference to other services in the area

get a clue
