By the way, how to measure the cable fault location without the 11807
software?

Pulling it back apart isn't an issue with the 130C if you apply it sticky side
out. Once you slit down through the vinyl and 130c with a knife, you can peel
it apart to open up the splice.
Yeah, its a little work to get it to release from the jacket of the cable...
but its doing its job

The 11807 software can make things a little prettier, but you can still do
return loss quite easily. Distance to fault is going to be a bit more
challenge, but it can be done too.
Return loss is the easiest to set up. You'll need to
I'll second that, Eric.
Have used that same procedure and materials for years on thousands of
connections in the cellular industry.
The only failures have been due to human error in the proper application, or
birds pecking the joint apart.
Scotch 130C is excellent stuff. I wouldn't use
Hi Scott,
Finally got to dig out my MSF manuals for a look.
Looking on the schematic, I see JU1 and JU2 being related to the HSR (High
Speed Ring) data bus. If this is the JU1 you moved, then it would change the
communication path between the SSCB and the TTRC and/or the SECURE board(s).
There are some trouble shooting charts... mostly in the PA section itself.
For the Power Control, there is a block diagram with explanation notes on its
operation.
Send me the model number and other particulars via email and we can continue
there.

Hi Scott,
Do you know if the power sense is hooked up/working?
I seem to recall having this issue when trying to use a MSF5k with a non-MSF
(Micor) PA.
Without the forward/reflected power from a VSWR bridge being fed back into the
MSF5k, I am pretty sure the shelf did what you describe.
Its

Hi Tim,
I hope you have a very large solar/battery plant if you are wanting to run a
Micor off it...
The Micor is by no means solar friendly.
Hook one up and measure the standby current, then plug those numbers into a
solar power budget calculator, and hang onto your wallet. :)

The newer L5PNF and L5PNF-RC (preferred) should also work for you, and are
easier to install.
If you can't find a Z-splice, you may want to round up a pair of 7/16 DIN
connectors (ie L5PDF-RC and L5PDM-RC). They are pretty much mechanically just
as strong as a Z-splice, but its much easier to
Yeah, plain 307's don't survive long in conditions like this, even with welded
elements:

That's why all the yagi's are Sinclair 307RCHD, Scala, Comprod, or other
similar designs.
I've seen dipoles snapped off Sinclair 210C4HD's too due to ice on other sites,
Sinclair makes decent antennas, but if you really want something to survive in
a harsh environment, check out Comprod Communications.

They make antennas that survive nearly anything. Out here on the West Coast we
routinely get lots of
Yes, either the Q202G or the Q2330 will do what you want.
Sinclair may have changed the spec sheet on the Q2330, but they haven't changed
the construction, so if tuned properly, you should get plenty of isolation.

Actually, the comment below isn't quite true.
The Q2220E is a Res-Lok duplexer, but there are no machined coupling ports
between the cavities. I just took the loops out of one to confirm.
The coupling between the cavities is a function of the pickup loop inside the
cavity, and the coax between
No, you're not off your rocker. :)
There already exist off-the-shelf commercial boxes that do what you are looking
for.
One is made by Omnitronics www.omnitronics.com.au and is their IPR100. You'll
need one at each end, and they are in the $1k range per box.
Raytheon also makes a similar
The IPR100 is just about $1k (CAN/US). I just got a couple to demo,
and that's the pricing I was quoted.

If you look in the File section, there is a pdf called 12Vmicor. It
is a short write-up on what I am using to make my Micor's run off 12V
direct. No reason why it shouldn't work for the MSR2000 too... just
need to find a convenient place to mount the LM317.
Use the standard circuit found in the
directly from your plant, and it will be happy.
I have used this mod on VHF and UHF stations... just check the manual
and make sure that the connections are same (there are a number of
backplanes out there in the field).

Hi Ian,
I look after a number of solar powered, mountain-top repeater sites.
Reduce the number of points of failure.
Use panels in your array with the same capacity, parallel them
together. With most panels this is easily done right on the back with
short jumpers.
Run the output of the array
That's not true Michel... per the manual:
They type of audio used from the receivers can be just about any type
as long as all of the receivers use the same audio. Audio types that
are acceptable are line level and speaker audio.
Also, it does not matter if the audio is de-emphasized or not as
Yeah, EIA or F flanges are an option, but a cheaper alternative would
be DIN connectors.
They are very common (low price point) as they are very common in the
Cell/PCS world these days. Probably about the same price as N
connectors.
The return loss through a DIN connector splice is comparable to
Sinclair is still pretty good... not as good as they used to be.
You might also want to look at Comprod antennas.
http://www.comprodcom.com/en/antennas/base/pdf/870series.pdf
They make some very good products that stand up in environments that
shred Sinclair's.

Ok, I've looked high and low... and come up short.
I am curious to see just how good/bad the audio frequency response of
my repeaters are. The problem is that I can't figure out a good way
to go about doing it.
I'm looking for information on how and what to use to check/plot the
audio
