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.

RE: [Repeater-Builder] Glenayre UHF PA
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. I found that if you run them at rated output that collector burns (solder joint fails due to repeated thermal cycling) occur fairly often, so I'd turn them down a dB or so. Glenayre revised the design later to put an L-shaped bend in the inductor feeding DC to the collector to try to get the resistance down to reduce the chance of collector burns/desoldering but it didn't seem to help much. Glenayre used to have flat-rate repair of $95 per PA strip (the driver and the PA boards are the same), but that went away a long time ago. Last time I tried to get a board repaired/replaced it was $380. The switching supplies that go with those PA's (two in parallel for a 250 watt PA) have been problematic for me. --- Jeff WN3A -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Chuck Kelsey Sent: Sunday, June 14, 2009 7:34 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Glenayre UHF PA OK, thanks.

Anyone know if a UHF Glenayre PA will work in the ham portion of the band? Chuck WB2EDV
Re: [Repeater-Builder] Glenayre UHF PA
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?

Re: [Repeater-Builder] Glenayre UHF PA
It is the 97 series.

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.

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.
