[Repeater-Builder] Re: Wouxun Radio
The Wouxun KG-UVD1P is a 2m/70cm or 2m/1.25m dual band hand held radio. It has FCC ID WVTWOUXUN04 for Part 90 use. Look here https://fjallfoss.fcc.gov/oetcf/eas/reports/GenericSearch.cfm put WVT in Grantee Code and WOUXUN04 in the Product Code. Spec sheet info: http://www.wouxun.com/Two-Way-Radio/KG-UVD1P.htm I bought the 2m/1.25cm version from http://wouxun.us/ at Dayton this year to give me a 222 mHz handheld, it has been working great, including surviving a 3 foot drop to concrete :) --- it operates 5W on 2m and 4W on 1.25m. (I prefer dealing with a US distributor vs. an Ebay Hong Kong dealer.) Advise getting a programming cable for setup. The software is available online from several locations, including the Yahoo Group at http://groups.yahoo.com/group/Wouxun_KG-UVD1/files/Software/ including software to set frequency ranges. (Within limits, you cannot move a 2m/70cm radio to 2m/1.25m for example) -- the programming software raises a false positive on some virus scanners. They are not on the Part 95 list (no GMRS, MURS, etc. though they will program there) same with Part 80 (I have some frequencies programmed to listen to some channels under both of these parts, but disabled transmit). They do not do AM, they can receive commercial FM broadcast. There is a long history of using Part 90 radios on Part 97 frequencies (Amateur Radio). Hope this helps clear things up and ends the speculation. The licensee is responsible for which radios are in use at their station or within their system (not the radio technician), so your mileage may vary. Personally, if I was working with a volunteer group and had a Part 90 licensed system, I would offer this as a low cost radio for volunteers. -- John D.

Yes, we have problems in our current laws and government, but we still retain the right of the ballot, and if we see problems there, we should look in the mirror for the solutions. If your legislators are writing laws that favor one group over another (e.g. the rich over the poor, corporations over citizens and natural persons, etc. -- the NRA over all other associations) you need to let them know your factual opinions on the subject. We need laws and taxes that are created on the best available current scientific facts, not those that protect the status quo, corruption by political contribution, or for sentimental/emotional issues. A few years back, my state of Washington levied a significant "tax" (rental fees) for any repeater on state owned land, the legislature was contacted and an exemption was made for amateur radio and the rent was limited to US$100/yr. which is an absolute giveaway for some of these sites. -- John D.

Re: [Repeater-Builder] Repeaters vs RC
Don't forget the FCC rules...in this case, I am only to assume (knowing MCH's identity) that this is taking place in Western Pennsylvania. That being said, my question is, if the repeater is coordinated by a governing body (WPRC) why would he/she complain about RC operations? The FCC rules, as far as I see them and have read, grant governing authority to the regional coordinating body to authorize said band plans per region. The operator of the RC equipment needs to yield way to the authorizing entity. Logical thinking, regardless of rules, would dictate that amateurs be good stewards of the frequencies they occupy and utilize appropriate 'channels' that do not interfere with other equipment. I would concur with 'DCFluX' in terms of getting crystals reground for a mere $50 (let's say) versus a repeater operator re-pairing, recalibrating, and retuning the entire repeater station.

Re: [Repeater-Builder] De-sense question
Hi John,
I'm providing a disclaimer now...: I'm somewhat unorthodox,
unconventional, and have a terribly dry sense of humor. I've been known
to dispense what others feel is bad advice. With that in mind, feel
free to try any of my suggestions with great caution. I'm leaving
myself open for a lot of heckling, but I'll try to keep my sarcasm down
to a minimum. I don't find the repeater "business" to be a great
science like some do-- a lot of it is common sense and elbow grease.
You can learn a lot by monkeying around and throwing stuff at the wall
to see what sticks.
So, moving right along, and in the words of Bill Clinton, "I feel your
pain." A couple of months ago, I started a new repeater project and had
all sorts of de-sense and noise problems. To me, it sounds most of your
problems are within your antenna system. Here are some suggestions (and
my stories) on how to get rid of noise problems...:
First, I like to put some space between any rigid feedline and my
duplexers. The physical strain of the hardline might be wreaking havoc
on your duplexer's wiring harness. I usually add anywhere between three
and six feet of LMR-400 (which many claim to be evil) between my
duplexers and my feedline entry point. RG-214/U might be a better
selection, due to its double shielding. However, its losses are a bit
higher per foot than LMR-400. I've been told (and have read) that when
LMR-400 moves around, it makes noise. While I believe that's
technically true, it probably is about any type of coax. I don't know
about you (or anyone else), but I don't go to the repeater site on a
daily basis and shake my feedline jumpers around, just to see if I can
see if they're going to make noise. ("HA! I got you now, you sneaky
noise demon!") I don't believe the repeater moves around-- unless it
gets up and goes out on the town at night while I'm sleeping. (Maybe it
just gets high on RF and "drunk dials" instead?) So, don't be afraid to
give it a try. In fact, I use LMR-400 between the repeaters themselves
and the duplexers. Even worse, I have a $47 diplexer (not duplexer)
separating 2m VHF and 70cm UHF, feeding into one antenna. SWR is fine
and I haven't noticed any loss in sensitivity. Both repeaters are tied
together, which means when it is in use, one receiver and two
transmitters are sharing the antenna and moving three virtual RF paths
simultaneously-- unless, of course, two people "double" on each band, or
if the repeater is ID-ing between talk times, et al.
Second, if you're not using silver plated connectors, seriously think
about using them. Don't even consider the run-of-the-mill teflon ones,
they're nearly useless in your repeater application. Anyhow, I bought
two sets of duplexers, one being Telewave TPRD-1556 VHF duplexers (6
cavity), the other being Telewave TPRD-4544 UHF duplexers (4 cavity).
Both sets were used, very clean and well kept, except the silver plated
connectors and coupling loops. I pulled each and every connector off,
soaked them in C-L-R overnight, rinsed them off, dried them off with a
cloth, then used silver polish and an old Ronson Roto-Shine shoe shine
kit to buff 'em and bring the shine out. After that, I rinsed them
rather well again and took a toothbrush to them to remove any remaining
polish paste. I put them on a baking sheet and into the oven for about
an hour at 200 degrees Fahrenheit. They dried nicely-- no moisture! I
disassembled the entire wiring harness and used RG-214/U for the coaxial
ties. Then, I pulled the coupling loops out, took copper polish to the
loops, rinsed them off, and put them in the oven for a little bit too.
After I was convinced that they were dry, I used clear spray
polyurethane on the loops to prevent tarnishing and inserted them back
into the duplexers. I took them back to a local, reputable two-way shop
to re-tune them. They're doing much better than they ever did before.
My temporary, 'el cheapo' antenna has an SO-239 connector. I have an
eight inch piece of coax with a PL-259 on one end and N female on the
other end coming out of the base of the antenna. I get a little crazy
with heat-shrink tubing, but I haven't had any problems there, either.
That was good at relieving any strain at the antenna connector.
Third, I have to agree with the pre-amp issue. That could very well be
the entire root of your problem. But, if you have the time and
resources, snag yourself about 20 feet of decent coax, a cheap $50
collinear antenna, and take the repeater home. Stick the antenna out in
the back yard. Try your pre-amp on the repeater, then without...note
your differences. The goal here is to see if your noise levels are
higher at the repeater's designated site or not-- whether your antenna
is behaving or not, and whether your feedline is behaving or not. That
would give you an idea of whether you have to climb the tower and poke
around or not. Might sound obv
[Repeater-Builder] ACC RC-850 Tone Panel Suggestions
Greetings, I'm wondering if anyone would have any suggestions on current market tone panels that will reasonably accommodate interfacing with ACC controllers. Particularly, I recently acquired an RC-850 (3.8 w/CIB) which I would like to accept both PL and DPL. Price is not an issue in either case-- I'm simply looking for something reliable, of decent quality which will passively do its job without hindering the controller's functionality. In addition, I have two RC-96 controllers (without the optional CTCSS boards) that I'm interested in finding some sort of tone panel or board that might reasonably hide in the case. I welcome your constructive criticism! Thank you kindly, John, NF3Q
[Repeater-Builder] Re: EF Johnson CR1010 Crystal Replacement
The new crystals basically look like most crystals except that inside the large can there is a smaller can. In the small can is the circuit board with surface mount components and the crystal. ICM said that it has laser cut resistors and there are no schematics for the boards and each one may be somewhat different so it is impossible to know what the value of the componenets are.

Eric, I tried that today and they positively will not work on the new type of crystal holders due to the way they are made since they cannot reliably make them work.

[Repeater-Builder] EF Johnson CR1010 Crystal Replacement
I have a CR1010 repeater that needs to have new crystals installed to change the frequency from 451.200 to 451.250 on the TX and 456.200 to 456.250 on the Rx. I tried to get crystals from EF Johnson and they said they no longer support this repeater. I then tried to get crystals from International Crystal and they said there were two types of holders new and old. They said that if I had the new type I would be unable to get crystals for them or they would never work. It just so happens this repeater has the new crystals so does anybody know where I can get a set of old crystal holders so I can change the freq. on this repeater? Also does anybody have any other good ideas on how I can proceed with this unit. Thanks
