Hi guys. My Waris radio (UHF) has a bad PA, probably by something dumb I did (I found the radio keyed up with no antenna in my carry bag, it was pushed up against something and got turned on I guess). As such, now it's running on exciter power, another portable 10 feet away doesn't receive anything. How hard is it to fix/replace the PA on these things?
Thanks!

In my humble opinion, when we get one of these with a bad PA we just sent it to the depot, where an IMUD replacement board is installed into it, it's flashed and aligned, and returned to us.
The other option is to locate a similar portable with physical damage but a good board, and replace the board.
Unfortunately WARIS portables (and mobiles) all utilize surface mount everything. Since the PA in the unit is blown and it's more or less useless as a transmitter, open it up and you'll see what I'm talking about.
The RF sections are all located underneath soldered/welded metal cans. Removing these cans would be a real pain in the neck, and would probably result in further damage if you didn't have the correct rework equipment.
This stuff was designed to go back to the depot or an MSS for repair, where the entire board-at-fault is replaced. I hate to say it, but the internal boards of these radios are more or less "throwaway" items.
If the radio in question is an HT1250 with a good display, I'm looking for an HT1250 limited or full keypad housing with electronics & good display to refurb a unit I have here with a broken display/trashed housing... Might be an opportunity to at least get SOMETHING out of it.
Wish I had better news for you.

I would pretty much echo everything that the previous poster said, however in many cases, better-equipped /\/\ service shops can handle that kind of repair, and more economically than flat-rate. Which will set you back around $285.
I can usually fix these in the $120-150 range. PM me if you decide to go that route.
