Chad dropped off two circulators this morning, they both likely need to be tuned, or at least verified that they do something at our freq. forem isolator, model no: S7384Z6007A5 400-470 MHz Looks like it has been used in the ham band as it is marked 444.525 MHz, and some isolation measurements.

Re: GB DMR Repeater Status

The Green Bay DMR recently had a PA failure and was not showing any output power (other than exciter). Chad and I swapped the RF boards from the respective TX and RX radios and we have power again.

We looked at using that about 2 years ago for the CS7000. Even if you were able to get C5000 chip to do ...
