The unit has been taken to Delmarva Communions and I am waiting on a diagnosis. Hopefully it will be repairable for a reasonable cost, I like the fact I can have a repeater to let everyone use. I have thousands in tower, hardline and antenna no to mention the the unit and a bunch of mobiles and ht's..hope it's going to be worth repairing for all to use.

oh nice, I'll look them up 2day. Thank you.

I tried using just one channel and then putting the original code plug i was given when I got the repeater and it still hangs on but now with static that's choppy. I tuned a new duplexer and still the same thing happens. Anyone suggestions on where to send a sick repeater near Delaware ? I did see one place in North Jersey, anyone have any suggestions on an affordable repair location ? Thanks everybody for the help....

Thanks for the reply Radioguy, I'll give that a shot in the next few days. All I have is a VNA but I don't think that will help much.

It still does the same thing. I am going bald pulling my hair out trying to figure this out...
-
it could be but it seems it has to do with receiver desence but its worth a shot, I will look farther to see if my serial-lot number is effected.
-
thank you I will check the caps and replace as necessary..
-
Well you know way more than I do about it, its really frustrating me to the point I am ready to give up after putting a ton of money into everything ... I just don't know where to start testing to see whats wrong.

lost me on that one, you are the PE I am just a hobbyist
-
yes it sounds like a feedback squeal and as soon as I push the repeater button to turn the function off it stops transmitting.
-
its definitely not that. I can be in the car a mile away and still get a sequel after the tail ends. I can even hear it through the speaker on the repeater. it will happen even with the duplexer removed and two separate antennas. It does it with or with out the duplexer.
-
Ok so this repeater on desk mode works as it should. On repeat mode it will repeat the broadcast, the repeater tail ends then when it does it still transmits but does so with a squeal and will not stop unless the power is turned off. Any suggestions of where to start ?
