Solved: [Repeater-Builder] Problems reaching the RB website

[kd6aaj]

AHA! I figured out your problem.
 
Drop the "s". It's supposed to be "repeater-builder" not "repeater-builders"

As of April 13, 2010 the updated http://www.repeater-builder.com page works 
fine for me.

It took me a few seconds before it redirected to

[Repeater-Builder] Re: A warning to Land Mobile Radio Dealers

[kd6aaj]

Strange, considering the GMRS can come with radios you buy, before you even 
have the license. I guess you have to be one of the BIG boys to sell radios 
preprogrammed with those freqs.

and there is an EXCEPTION:

Title 47: Telecommunication
PART 90—PRIVATE LAND MOBILE RADIO SERVICES
Subpart N—Operating Requirements

§ 90.427   Precautions against unauthorized operation.
(a) Each transmitter shall be so installed and protected that it is not 
accessible to or capable of operation by persons other than those duly 
authorized by and under the control of the licensee. Provisions of this part 
authorizing certain unlicensed persons to operate stations, or authorizing 
unattended operation of stations in certain circumstances, shall not be 
construed to change or diminish in any respect the responsibility of station 
licensees to maintain control over the stations licensed to them (including all 
transmitter units thereof), or for the proper functioning and operation of 
those stations and transmitter units in accordance with the terms of the 
licenses of those stations.

(b) Except for frequencies used in accordance with §90.417, no person shall 
program into a transmitter frequencies for which the licensee using the 
transmitter is not authorized.

and:

§ 90.417   Interstation communication.
 top 
(a) Any station licensed under this part may communicate with any other station 
without restriction as to type, service, or licensee when the communications 
involved relate directly to the imminent safety-of-life or property.

(b) Any station licensed under this part may communicate with any other station 
licensed under this part, with U.S. Government stations, and with foreign 
stations, in connection with mutual activities, provided that where the 
communication involves foreign stations prior approval of the Commission must 
be obtained, and such communication must be permitted by the government that 
authorizes the foreign station. Communications by Public Safety Pool eligibles 
with foreign stations will be approved only to be conducted in accordance with 
Article 5 of the Inter-American Radio Agreement, Washington, DC, 1949, the 
provisions of which are set forth in §90.20(b). 

[43 FR 54791, Nov. 22, 1978, as amended at 62 FR 18933, Apr. 17, 1997]

---end of CFR regs---

So, what's to stop someone from saying they programmed a freq for emergency use 
only? Why else have the exception, unless you are expected to have an 
"unauthorized" frequency programed in your radio?

So, the exception (90.417) clearly makes 90.427 un-enforceable UNLESS you can 
prove intent to operate on the "unauthorized" frequency for NON-emergency 
communications. The school was operating on the frequency, but they don't say 
what kind of communication was involved.

Hi All
Looking for small etched, maybe drilled, small boards with layout for
several transistors, resistors etc all isolated pads

Also looking for ones that have layouts for 8pin, 14 pin or 16 pin dip with
isolated pads for hook up

I have some misc of the above and they are great for inverters, buffers,
little op amps for increasing the level of the disc or tx audio.

Any ideas?

Re: [Repeater-Builder] Re: How to remove Scotch Kote

[kd6aaj]

I use Lysol® Brand Bathroom Cleaner with Citric Acid as the active ingrediant. 
It is pretty caustic. I switched to that when my wife was pregnant, not as 
nasty as chlorine bleach (or the gallon of murriatic acid I have) but 
ventilation is a must.

Or, go to the pharmacy and get some powdered citric acid and mix with water 
(wear personal protective equipment: goggles, gloves, etc). Citric Acicd is 
supposedly pretty good for PC-Board etching...have to try it some time.

Re: [Repeater-Builder] Strange BNC-like connector

I've got an old piece of HP test equipment that has a very strange BNC 
connector on the back. Initially it looks just like an ordinary BNC female 
jack, and an ordinaryh BNC male connector will start to fit it, but...

It has THREE little nibs sticking out the sides at 120 degree offsets, instead 
of the usual two nibs 180 degrees apart.

I've not come upon any other connector like it. A regular BNC male will fit 
inside but the locking ring with two slots won't mate with the three nibs on 
the outside of the jack.

RF Connectors doesn't have anything like it, and I haven't seen one in the 
Mouser catalog. I could post a photo if it would be helpful.

Anyone have a clue?

I also like the "Orange Goop®" hand cleaner (the kind with no pumice or

I have used it to get Black-Jack tar off my hands when running conduit on a 
roof. Also removeing tar off the family car. Made in USA! I find it at the 
local dollar store sometimes, and buy several at a time.

Re: [Repeater-Builder] Who is Scotch Kote?

[kd6aaj]

Scotch Kote is a 3M product, amber to brown in color (I've seen black, too). 
Another brand sells something called "Liquid-Tape", essentialy the same thing, 
but I think Scotch Kote Dries harder, where Liquid Tape is more like tar, and 
gets tacky when hot.
 
It is designed for sealing electrical connections against moisture or dirt, 
typicaly used to seal electrical tape wrapped around coaxial connectors and 
high-voltage (up to 480VAC) connections.

Re: [Repeater-Builder] LMR-400 Cable

I suspect you my need "hardline" for that distance.
 
I have an interesting theory...
 
What if the length of coax actually were actually long enough for the tx signal 
to remain on the wire while in RX mode? Probably need to be a mile long ;)
 
Another thought; anyone ever run seperate long cables from the TX and RX 
cavities to the combiner (splitter) on the antenna side while the combiner was 
close to the antenna?

I recently put a six meter repeater (52.810/51.110) on the air here in 
Anchorage, Alaska.  I am feeding it with about 60 feet of LMR-400 cable and am 
experiencing quite a bit of desense. I did a search for "LMR-400 in duplex 
operation" and came across several posts from users of this list and decided to 
sign up and investigate some more. I am running a GE Master Pro at 100 watts 
into a 8 cavity Sinclair duplexer. The antenna is a Diamond co-linear mounted 
about 35 feet above ground at the present time. I live on a hill here in town 
and currently have the repeater mounted at my home qth. When I terminate the 
duplexer into a dummy load and look at it with the spectrum analyzer it 
performs very well with no desense. Connecting up the antenna is another story 
altogether. I have been pulling my hair out over this one thinking it must be a 
duplexer problem. Originally I fed the antenna with RG-213 which I know is not 
the best choice for repeater use but it is
 what I had handy at the time. I was getting desense with the RG-213 so I 
switched to the LMR-400 since I had a roll someone had given me. I actually 
think I had slightly less desense with the RG-213.  Is the 400 really not that 
suitable for duplex operation even at 6 meters? What would be a good alternate 
choice ?

[Repeater-Builder] seeking executive mobile radio information

[kd6aaj]

I have a low-band RG64TCN22 GE Executive Mobile, including the slide-
on bracket (I used a "10A" key to unlock it).

According to the LBI list, the maintenance manual I need is LBI-3748.
It is not in the LBI section, or on the "Wish List".

Incidently I DO have LBI-4124 for Master Progressive Line, which is 
on the "Wish List".

According to the numbers, this radio is a trunk-mount mobile,12VDC 
negative ground, 38-64 Watts, 20 MHz channel spacing, 33-42 MHz, 2 
freq TX and 2 freq RX.

I don't have the control head, but the inside is sparkling clean, no 
dust, corrosion or any other signs of physical damage! The one 
crystal in it reads 43 MHz. It has 2 tubes in the PA.

I got it in 1993 as a left-over from the 2-way shop I used to work in.

If I can get it to work, I could make a 6 meter repeater out of it.

Does anyone have info on this beast?

73, KD6AAJ

RE: [Repeater-Builder] seeking executive mobile radio information

[kd6aaj]

Thanks Eric!

Maybe I can trade it to someone local who wants one. I'll have to see if I have 
the other crystal somewhere, and see if I can turn it on. With no manual, it is 
almost impossible to know where to start.

I had a Mocom 70 also, but I think it got tossed before we moved. I'll have to 
look for the Mocom 70.

If anyone here desperately needs some parts from it, let me know.

Re: [Repeater-Builder] Motorola transistors

[kd6aaj]

I have a motorola RF Data book that has transistors in it. I'll try to find the 
book and see if they are in there.

Re: [Repeater-Builder] 2 meter noise help!

[kd6aaj]

Yep, sounds like high voltage noise from a dirty insulator, more noticeable in 
foggy conditions. Dirt attracts moisture and at 12,000 Volts (or whatever the 
potential is) you get small shorts that crackle, like in the back of a dirty TV 
set.

If you track it down to a Power Company's insulator, give them a call.

I was working at a saw mill one night when the substation there went down from 
saw dust accumulation on the insulators.

Re: [Repeater-Builder] OT Fish paper

[kd6aaj]

Maybe google for "Micarta". We use it for Hi-Voltage (480 VAC) stuff. Material 
we use is thicker than fish paper, though.

If I find any info on "fish paper", I'll post it.

OK, I guess the info is found, I'll leave at that.

70% Isopropanol Alcohal is my favorite cleaner. Make sure all power is off to 
the radio, and give it a few minutes to evaporate before restoring power.

Leave them a note, tell them it’s a CLOSED repeater system.  ( Sorry, I 
couldn’t resist..)  Are you in a cold climate area or is the repeater in a 
WARMER area than the outside ambient air temp? - M

Hey guys,
I am sure many of you have been through this before.
The evil mice decided to waunder in to my repeater sight. Up until now they
avoided my repeater, but when I went up there, I was less than pleased.
They didn't chew any wires thank god, but they walked across the top of the
icom rp4020, and left some presents if you know what I mean.
I need some input, what's the best way to clean it up, anything in
particular?
All the covers were on, so I don't think they got inside, but haven't pulled
the cover off yet.
Any ideas?

Thanks,
Jed

Re: [Repeater-Builder] Getting mice out of a repeater sight

The only reason I suggest alcohol, is it is not corrosive to the electronics.
 
O course, if you remove the covers and use bleach, that is ine, as long as you 
rinse them off.
 
I like to use bleach for everything in my house. And Lysol wipes, or the 
"Kirkland" branded wipes from Costco.

Re: [Repeater-Builder] OT: Tape

[kd6aaj]

Rubber tape is good for high-vibration environments, where the insulation could 
get rubbed off over time. The rubber would get worn down before the insulation. 
Apply cloth tape over it to keep rubber from dripping off in high heat.

Cloth tape is good for higher temps (won't stretch like plastic), and you can 
tie it in knots :) BUT, cloth tape attracts moisture!

Cloth tape is good for base-ball bats! :)

I like Super 88 and 33+, depending on the application. 77 is the cheaper stuff 
I use to tape wires together and pull through conduit.
