Get down to your local ham swapmeet and start catching up. Of Hmm... Last Swap meet I went to (Pacificon) was mostly boat anchors and parts for them. about the only 50 Mhz stuff was some tband mastr II's. I did find deal on a piece of heliax but other than that, pretty useless. Anyone know if there are any swap meets in the SF bay area that have repeater goodies? Steve P. Yahoo!

Re: [Repeater-Builder] Re: [Motorola] MSR2000 PA Transistors
At Pacificon, that is usually the case. I have been somewhat lucky in the past when I did find something there ... then it's a 12 hour or so drive back home. Worth the drive? Not so for only obtaining parts - but if your system is dead or dying, then yes. I do enjoy attending Pacificon as I know a lot of people who attend - this is my chance to visit with them For those of you who don't know about Pacificon: http://www.pacificon.org Steven Passmore wrote: Get down to your local ham swapmeet and start catching up.

Mitch, RF Parts does list the M9625 on their Web site. Dunno how much $...

I need them for the Forestry Repeaters in South Carolina. I've tried to find a 2N6097 or an NTE356 on line they are obsolete if they are available they are probably 3 digits in price! If you find a good source let me know and I will use the lite blue plastic card and buy some for the shelf Old working Micor's mobile is a good source for the transistor.

[Repeater-Builder] Re: [Motorola] MSR2000 PA Transistors
About a year and a half ago I replaced the whole board on my VHF MSR2000 110 watt NCD PA. (My PA had more problems than just the transistors) I used the PA board out of a 110 watt mitrek mobile. It took me an afternoon to do it as I recall. I had to remove the power control circuitry and change some values of some resistors on the input side of the mobile PA, but it still works great today with a nice clean output. MSR2000 PA's are notorius for failing, especially the NCD units. You could not back the power down enough and still maintain a clean output, no matter how much air you blew on and out of the PA. The CD units faired a little better, but those darn ham operators could fry them too! Ha! Ha!

Ken, The M1134 PA transistors, AKA 4884411L34, are identical to the M9625, which are AKA 480086925. These are no longer available from Motorola. However, the M1134 can be replaced by the 2N6097 or the ECG356. 73, Eric Lemmon WB6FLY Ken Cechura wrote: Anyone know where I can find MSR2000 finals?
