I opened the unit and no signs of burning at all on any of the 4 PA boards or the driver. I did follow your thread about the unit and get the idea they're not that economical to repair if needed. I haven't fired it up yet but everything looks ok at least. Assuming it's working properly as is, I'm thinking about pulling 2 of the boards, didling the hybrid xfmrs a bit and keeping the unused boards as spares (they all have the wire in the collector connection to help with the heat expansion issue). I'm thinking 250 watts is perhaps 3 dB too many so running it @ 125 (and only needing one supply) would give me a spare there too. Anyway, I'll contact you offlist about the manual possibility.

[Repeater-Builder] Glenayre UHF PA (revisited)
Resurrecting an old(er) thread. I just picked up a Glenayre Series 97 250w UHF amp (with switcher supplies) of Ebay. The price was too good to pass up.

The 97 series will work OK in the ham band. The "twisted wire" hybrids are rated for 450-512 MHz, so the balance may be a little off, and the isolation degraded a bit. I have a few in service.

Re: [Repeater-Builder] Glenayre UHF PA
Chuck, We are running a couple of the 97 series amps on UHF and one on VHF. The ones on UHF are at the freq's of 434.050, 442.250, Both of these are 250 W and we are running one on 443.750 125 W Thank You. John Installer/Tech Midstate Communications 1st Lieut, S.T.V.F.D.

I'd bet it will tune down to at least 445 if it is a midsplit one to begin with. Worst case, you may have to move of the caps on the stripline a bit.

Re: [Repeater-Builder] Glenayre UHF PA
I have Quintrons (QT-6700) and they work just fine - I've had them as low as 441 with no problem. Also, been running one rated at 90 watts pretty much 24/7 since 1984.

Chuck, Not being sure which model Glenayre PA you're referring to, I'm running several QT-7795 and QT-6775's on 442 thru 449 with no degradation. Do you have a "QT" series or the 97 series?
