It's been up on the Motorola page since mid-March.
I added it to the test equipment page just recently.

I prefer AC fans because they generate less noise.  I do have some 12 V CPU 
fans on the backs of a couple of MVPs in service, but have had problems 
with low levels of fan noise on some of them.  If you have a choice, AC 
fans are easier to work with IMO.

[skipp025]

Email me direct a few very well lighted pictures of the 
capacitor and put something near it as a size reference 
(like a dime or a quarter [two-bits]).  I've heard a story 
that hams have been known to have parts like these in their 
"junk box" (aka spare parts bin).

[Repeater-Builder] STX Model Configurations / Nomenclature

[La Rue Communications]

Not sure if Nomencature is strictly GE terminology, but I used it all the time 
now when dealing with model number breakdowns.

I have a room full of assorted Motorlola STX portables. I am trying to make 
sense of these sticks and want to get them in the right spot in our shop. In 
other words I want to separate them by bandwidth, and capabilities. I've tried 
several forums, including BatBoard, in vain. Google searches turn up Batteries 
for this thing, but nothing specific.

Can anyone out there help me out, or point me in the right direction please?

Thanks!

Gary,

Try Viking Technologies LTD. at www.cardwellcondenser.com
they have a very large selection of Johnson, series 167 capacitors and will be 
able to give you the exact specifications on the broken one that you have.

Re: [Repeater-Builder] Wanted: G.E. VHF HB UHS preamp

[Scott Zimmerman]

Bob,

I have some.

You gonna make the big show this year? As we have in the past few years 
Elisha and I will try to make an appearance at the Hamvention for at 
least one day. I'm not sure if it will be Friday or Saturday yet.

Repeater-Builder will not be making an appearance at this year's show. 
It's just too hard to wrestle kids and such. With Kevin having a steady 
job again, it's tough for him to get off to go anywhere. (I don't think 
he's had a vacation since he got this new job!!)

At any rate... Bob, If you're going to make the show, I can bring you 
what you need. If not, I can send it in the USPS. They still deliver 
mail don't they??

[Repeater-Builder] Wanted: G.E. VHF HB UHS preamp

[no6b]

Bought one several years ago from Kevin @ the Repeater-Builder booth in 
Dayton.  Works very well (~0.13 µV for 12 dB SINAD on the MVP it's in), but 
now I need another one.  Got another one, Kevin?  If not, does anyone else?

BTW, I did the antenna-load sensitivity substitution test last night on 2 
MVPs, one with & one without the preamp.  The MVP with no preamp showed ~5 
dB SINAD degradation between the antenna & load.  With that much noise 
coming down the antenna, reducing the noise figure of the RX doesn't help 
much, maybe a dB or two.  But once you throw in the duplexer loss, which in 
this case is 2.1 dB, the antenna noise is reduced to only 3 dB over the 
load.  Now the preamp improves actual sensitivity by 3 dB, which is just 
enough to make it worthwhile to use IMO.  In addition, this will be for a 
portapeater that will be deployed in a rural area so the antenna noise will 
probably be lower.

I already found that one, thanks anyway, the 167-205 is close but not enough
plates, mine has 6 rotor and 6 stator.  Physical size is right though, 
maybe this

cap was made by Johnson also since the numbers are close.

[Repeater-Builder] Duplexer parts

[Gary Hoff]

I have an old Phelps Dodge VHF Duplexer that has a
frozen air variable.  The Duplexer is a part# 499-509 and
covers 144-174.  The air variable in question is stamped
167-202 and is split stator about 1 3/8" square.  Anybody
know where I might find a suitable replacement, I haven't
had any luck where I've been looking.

[Repeater-Builder] Re: Kenwood Service Manuals (TOS/COS question)

[skipp025]

No problem trying to help you out...  And now a 50 cent plug. 

As a fully Authorized Kenwood Dealer AND Service Station (for 
repairs) and I should be able to provide access to available 
Service Manuals. 

Many of the Service Manuals for the older radios are/were only 
available in printed form (versus an available PDF version more 
easily sent by Email attachment).  I probably have a shop copy 
for your radio and I could also check on an available printed 
version to sell if you really wanted one.  I'd be happy to offer 
that service. 

But there are many similar sounding (written) model numbers for 
radios that are quite different from each other so you/I have to 
do the proper homework to ensure you end up with the proper 
manual.  A Kenwood tk-860 is not the same radio as a tk-860g is 
not the exact same radio as a tk-860H. I hope you get the idea 
that I'd like to avoid ordering the wrong manual(s) where 
possible. 

One last item... I'm up to my "arse" in "California Alligators" 
right now... meaning (regardless of the posts you see here) my 
time is almost 100% on some very special high-level projects 
with really short time-to-complete deadlines.  So I haven't been 
as accessible or replying to Emails and phone calls as I would 
like.  So if you need to reach me, please be patient and pestering 
with Email is probably the  best way. But I/we will be happy to 
try and help you as our available time allows. I guess I/we should 
be happy to report things "are very busy right now". 

Thanks much, 

Resume ALL-SKATE, All skate slow and safe.
:-) 

cheers,

I have several of these cavities, they are Wacom VHF Band Pass filters, and
