Randy,
I could use some UHF Mitrek radios.
The numbers on the radios should be

UHF RADIO FCC TRANSMITTER NUMBER

T34 = 30 watt
T44 = 50 watt
T64 = 75 watt
T74 = 100 watt

UHF RADIO CHASSIS NUMBER

HUE1001B = 406 - 420 Mhz (30 watt)
HUE1002B = 450 - 470 Mhz (30 watt)
HUE1147A = 470 - 512 Mhz (30 watt)
HUE1011B = 406 - 420 Mhz (50 watt)
HUE1012B = 450 - 470 Mhz (50 watt)
HUE1153A = 470 - 512 Mhz (50 watt)
HUE1032B = 450 - 470 Mhz (75/100 watt)
HUE1033B = 470 - 494 Mhz (75/100 watt) 

The HUE1147A, HUE1153A, and the HUE1033B are not usable for my needs.

Thanks,
Joe - WA7JAW

 Hi Howard..Well, your in luck. I happen to have one 110 watt 
VHF Mitrek avaiable for sale. I also have a 110 watt Motrek also. The 
Motrek is identical to the Mitrek except for the color. It's more of a 
brownish color, but it's identical to a Mitrek in every way. The Mitrek 
is a  T83JJA3000 and the Motrek is a T73JEA3000. The Motrek is already 
on 158.400 MHz. They both are in terrific condition. Both are working. 
Top and bottom covers are there.
 They are pretty much the last of the Mitreks I have. I have just the 
transcievers, no accessories. If you need elements, I have those too. 
I'll throw them in. If you need a certain PL freq, I'll see if I have 
the reeds. I'll take 30.00 each for them. I know you won't be 
dissapointed with them. Also, if you want to change the color of the 
Motrek, I can give you the name of the spray paint to buy. It's a dead 
ringer for Motorola's "Shadow Bronze".
 Let me know if your interested.  Thanks Ed Voccola KA1UNJ

Micor and MSR2000 amps show up on E-Bay fairly often...  1/2 watt in gets

Check the model numbers or pix:  there are intermittent (shallow heat sink

Thanks Paul. I agree with you on everything you said.  One thing is for

I finally got to talk to a guy at dbSpectra today.  He vaguely remembered
the different loops but couldn't remember how they were installed.  He was
going to try to find some old tech data and send it to me.  I haven't seen
it yet, but hopefully it's coming.

Mike,

OK, that makes sense re the 004/005 markings.

And OK on the knobs. That really messed with me at first. I thought 
they were glued or something. It was only when I tried heating one 
to see if the glue would soften that I found out it was solder!

I didn't have any trouble with the top of the inner tube catching on 
the finger stock when I put them back in, but it was a real close 
fit getting them in without that happening. On each cavity there 
were, as I recall, two or three fingers that were sprung inward a 
little more than the others, possibly having to do with the ends of 
the two coil springs putting extra pressure on them. Those were the 
ones I had to watch closely.

As long as it hasn't compromised the solder bond of the finger stock 
in some way, I'm not sure the worn copper plating will do much harm. 
Of course if the copper plate between the finger stock solder and 
the inside of the fixed inner tube has deteriorated in any way 
(which you can't possibly determine by looking), then that would be 
a serious issue. My guess is it's probably OK. I would just clean 
them up as best I could and try it.

If you can't find someone who knows where the 004 and 005 loops go, 
I would try an experiment. I would put both 004 on one side of the 
duplexer, both 005 on the other side. I would then tune it up for 
high pass on the 004 side (low on the 005) and make a note of the 
performance measurements (notch depth, insertion loss, VSWR or 
return loss - measure all parameters on both low and high pass sides 
of course). Then I would retune it so the 004 side was low pass (and 
005 side high pass) and measure the performance again. If there was 
any difference, I'd go with the configuration that produced the 
better numbers. If you try this, I would be interested in what you 
find out.

Having said all that, it's also possible the loops were intended to 
go the way you found them... one 004 and one 005 on each side. That 
wouldn't be my first guess, but it's possible. It might have 
something to do with making the impedances look a little nicer or 
some such...
