Re: [Repeater-Builder] Re: Building Low Band Loop Antennas (DB-212)
First, don't expect to land exactly where you expect simply by adjusting the lengths to a specific dimension. You really need to place the antenna on a tower to adjust properly and use an antenna analyzer. The length of feedline from each antenna remains the same. You need to shorten the length of 35-ohm cable that attaches to the tee and heads toward your radio. This needs to be 1/4 wave taking the velocity factor of the cable into effect.

Chuck Kelsey wrote: First, don't expect to land exactly where you expect simply by adjusting the lengths to a specific dimension. You really need to place the antenna on a tower to adjust properly and use an antenna analyzer. grin Reminds me of my first experience with a Cushcraft AFM-4DA (4 bay exposed dipole array for 2M) about 30 years ago. I put it on a nice galvanized mast and mounted it to a tall building free and clear of anything. While the antenna worked - it really didn't perform any better than a 5/8 wave ground plane. I realized that optimum gain was not being achieved because the dipoles were spaced around the galvanized support and weren't really in phase to help each other out. OK, no problem, I'll put them in a line all above one another. WOW, the gain in the direction where the dipoles were facing was fantastic - so, I fixed the gain problem - BUT I created another problem. The null in the opposite direction was so deep that the system didn't work where I needed it to (I really needed omni coverage - I couldn't suffer with a null anywhere). OK, no problem, I'll put the elements on a FIBERGLASS pole. I bought a hefty fiberglass pipe and carefully mounted the Cushcraft array to it - mounting all of the dipoles above one another will retain the gain, and the fiberglass pipe won't create a null - problem solved right? NOPE - a rubber duck would have performed better! What happened? This type of array REQUIRES the element to be in the presence of a metallic mast - otherwise the impedance of the element isn't close to 50 ohms. I didn't have the ability then to measure return loss or actual impedance of the individual dipoles, but I can guarantee you it wasn't close to 50 ohms. The antenna didn't work and the reflected power was awful. I used a Bird and hand-held to feed one dipole - while moving the distance between the dipole and the metal mast pipe - sure enough, when you got to the distance the mount was designed to give, the reflected was at a minimum. SO The distance between the antenna and the support varies the port impedance. Bought a Sinclair SRL-229 (super stationmaster type) and life went on Certainly on low band the concern of the elements exactly above on another is of a lesser concern because the difference in phase angle is likely less - so obtaining good low angle gain in an omni directional pattern is doable.

[Repeater-Builder] Zetron 38A not sending reverse burst
I am trying to get a repeater going using a 38A and find that it doesn't send reverse burst.

[Repeater-Builder] Midland 13-513 COS Point
Please refer to the following: http://www.repeater-builder.com/midland/midland-13-513-owners-manual.pdf On the AF board locate Q202. Right next to it there is a yellow wire going over to Q204. You may either connect to the yellow wire or the collector of Q202. This signal is almost non-existant and if it is weighted down too much the squelch gate will no longer function and audio will not be heard from the radio. A high gain transistor is recommended as a buffer, preferably a Darlington transistor such as the MPS-A13 with a 2.2K - 10K resistor on the base. A FET such as the 2N7000 might also work. If no such transistor is available, a standard NPN such as the 2N3904 may be used as the buffer, but the value R222 will have to be changed to 330 - 1K depending on the resistor that is in the base of the NPN you just added. A small amount noise may also begin to leak if R222 is made too low.
RE: [Repeater-Builder] Zetron 38A not sending reverse burst
You have discovered one of many dirty little secrets that apply to aftermarket tone panels. When designing the 38A tone panel, and many other products, Zetron overlooked the fact that reverse burst is essential in the repeated audio. From a close examination of the 38A manual and schematics, it appears that it will decode CTCSS reverse burst and CDCSS turnoff code, and MAY generate CDCSS turnoff code, but I see no evidence that it can generate reverse burst. That alone is a major shortcoming! Zetron is not the only manufacturer that ignored reverse burst encoding when designing a community repeater controller. Instrument Associates, which produced the i20R On-site Repeater Controller for the Motorola GR1225 desktop repeater, did likewise. I did not realize this until I found that squelch crashes were immediately heard as soon as I put the i20R in service. Although some fans of the old Highway Patrol shows starring Broderick Crawford may enjoy the sound of a squelch crash, I do not, nor do any of my radio users. That i20R was pulled from service immediately, and put on the shelf! There are two different formats for CTCSS reverse burst STE (Squelch Tail Elimination) that are defined in TIA-603-C, the international standard for land-mobile radio performance and design. One format, used principally by Motorola, uses a 120-degree phase shift, while the other format, used by Kenwood and many others, uses a 180-degree phase shift. Since modern radios often use digital signal processing to encode and decode low-speed data (CTCSS and CDCSS), it is all too easy to design a circuit that responds perfectly to 180-degree phase shift but ignores 120-degree phase shift, and vice-versa. Zetron and others couldn't be bothered to create a CTCSS encoder that could be switched between the two reverse-burst formats, so they just ignored the problem. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of wspx472 Sent: Wednesday, November 18, 2009 10:15 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Zetron 38A not sending reverse burst I am trying to get a repeater going using a 38A and find that it doesn't send reverse burst.

[Repeater-Builder] Re: Zetron 38A not sending reverse burst
Thanks for the reply. The 38A sounded really good until I started to try to program and install it. The more I fool with the thing, the less I like it. After getting all my levels set up, I sent varying frequencies starting at 200 HZ and going to 3 KHz to check the response. I noticed a roll off above about 1.5 KHz even though I have all jumpers and switches set to flat. Upon checking with a scope, I find it is occurring in the 38A. I also noticed that the audio through the repeater isn't as crisp as it is on direct. Of course it is also passing through a receiver and transmitter but I kind of think that 38A is causing some of the problem. I really wanted to get this thing on the air next week but I am seriously considering scrapping the controller altogether. I have a TS-64 I can use for PL decoding and encoding and I think I saw a Com Spec IDer around. I also think there is a CAT200 around but I am not too fond of them either. Looks like decision time. --- In Repeater-Builder@yahoogroups.com, Eric Lemmon wb6...@... wrote: You have discovered one of many dirty little secrets that apply to aftermarket tone panels.

RE: [Repeater-Builder] Uniden Key
Bummer! Even if Uniden did not use the same cutting code on all their keys (like the Motorola 2135), the first step is identifying what key blank is used. Curtis and ILCO are two prominent makers of key blanks, and almost any key in the world can be found in the catalogs of one or both companies. Back when I was a teenager, I learned locksmithing when I worked at a large hardware store. Often, an appliance manufacturer would register a standard key with locksmithing organizations, so that the correct key blank and the cutting code could be duplicated without having an original key to copy.. There are key blank suppliers that will sell you a package of ten blanks for about ten bucks, and you can then have them cut from your original key at almost any key shop. The big issue is having the right key blank to cut, and that is where many small hardware stores are not much help. The majority of residential locks can be satisfied with just a few dozen blanks; commercial and high-security locks will run into the hundreds of different blanks. I have never seen a Uniden Force 1100 radio, so perhaps someone who has one can take some pictures of it. The Uniden Force name also applies to CB and GMRS radios. Even more helpful would be finding the Uniden part number of the key in the service manual. Who knows, perhaps that part number can be decoded by a key blank supplier in a few seconds. Perhaps I'm overly optimistic...? 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Scott Zimmerman Sent: Wednesday, November 18, 2009 12:49 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Uniden Key Well I struck out at all the places I stopped.

A website by WA1ZYX has a couple of pages on modifying the DB212 for 6 meters and also cable lengths/matching and spacing of the folded dipoles. No info on changing element spacing from tower leg. This could affect the pattern. Also found a 4 page article by Decibel Products titled DB212 Series. Good info on antenna patterns. BTW, I've got a NOS DB225 cut for 75.70 MHz. This is like a DB212 with a director. It's got all the measurements for spacing for director, etc so this probably will be critical. I was thinking of trying to extend the elements for 6 meters. Has anyone done this on a DB225? Ken WA6OSB
[Repeater-Builder] Re: Early FM Repeaters (tubes and more)
Less and less... more Government Agencies out here end up dumping the equipment at metal salvage locations. Here on the left coast they seem to be less interested in making it easy for the public to buy their surplus items in any decent kind of a deal. So I ended up buying racks of MSR-2000 Gear by the pound in addition to Mastr ii repeaters that went to the chopper still mounted in their Chatsworth aluminum racks. Also making the salvage death trip was an entire Motorola Type 2 trunking system... My trailer was only so big... and full. s. I'm not too disappointed, since us hams will be the beneficiaries. Bob NO6B The disappointing part of narrow banding is the text in the below message. I've been able to narrow band a heck of a lot of repeater equipment. Surplus repeaters and radio equipment are a gold mine to innovative and motivated radio people, who are willing to do both the homework and technical work. It's a lot more expensive and sad to think a lot of equipment is being replaced, when other viable options are available. s.

Hi Ken, I'd be interested in the web page url for the WA1ZYX web page and the other information if you'd be willing to share it? I have a DB-212 cut and working on 6m and the same type of antenna on 2m with the director. I will as time allows document those antennas and make that information available to the group. s.

At 11/18/2009 15:35, you wrote: Less and less... more Government Agencies out here end up dumping the equipment at metal salvage locations. I'm surprised that can do that, or at least get anything substantial in return for it considering all the hazardous materials in that equipment that must be disposed of. When it's sold back into service, the hazardous/toxic waste issue disappears. Bob NO6B
RE: [Repeater-Builder] Uniden Key
The key photos from both Scott Zimmerman and Kevin Valentino are up on the keys Page The name cast into the key blank looks like Takigen (it's a Japanese radio, do you really expect something from Chicago Lock ?), and I can't make out the third digit of the key number - it's 02(something)0.
