  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:

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?

[Repeater-Builder] Re: [Motorola] MSR2000 PA Transistors

[Gary]

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!

Re: [Repeater-Builder] Re: [Motorola] MSR2000 PA Transistors

[Neil McKie]

  People have been wondering why I seem to 'collect' all those old 
 used Motorola and GE radios.  I usually 'collect' them at swapmeets 
 when the sellers can't give them away (except to me.) 

  I finally unloaded almost all of the tube gear except one - even 
 donated a GE MT-16 to a friend in the San Francisco Bay area 
 sometime back. 

  Why not?  The manufacturers quit supporting them years ago.  

  I have Motorola back to the later Motracs, Mocom-70's, Micors and 
 Mitreks. 

  I have RCA to Series 700. 

  I have GE in Mastr-Pro (very nice radio) Exec II and Mastr II. 

  Those here who have seen my garage will ... groan ... 

  Get down to your local ham swapmeet and start catching up.  Of 
 course, you'll raise the price to me ... but the parts will be used 
 by someone and not hit the scrap yard.

Do what most of us are doing, buy used Motorola 
radios of the same era/type and lift the transistors 
from surplus radios. 

I purchased 40 used mitrek 110 watt radios for 
replacement UHF MSR PA Modules. Although the 
remove and replace process takes some 3 plus 
hours of serious work, the much lower cost 
offsets the financial pain.

The same would apply with with the VHF pa, which 
also depends on whick of the 3 or 4 known VHF 
PA versions you have. 

Ebay and the surplus radio dealers are good part 
sources.

Mitch,

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

I do not think you will find them anymore... I ned 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

Old working Micor's mobile is a good source for the transistor.

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.
