Re: [Repeater-Builder] Re: off site extra RX
Haven't been following this thread that closely, but if Mobile to repeater coverage in your downtown core area is good but HT coverage is marginal, (and coverage everywhere else is acceptable) why not 1. try a preamp on your repeater receiver or 2. consider changing out the cabling from the repeater antenna all the way back to the receiver to reduce line loss to a minimum. A 6-10 db gain preamp should bring the HT's up out off the background equal to the mobiles. Maybe you could borrow on long enough to try it out and see it it helps before you invest in one. I run preamps on all my UHF repeaters without any problems. VhF is another thing because of the narrow spacing on the Ham band but if you have a wide spaced VHF system it should work as well. Reducing you cable line loss , plus a good tuning of the receive side of the duplexer and repeater reciver wouldn't hurt either, if you haven't already done so. My 2 cents worth. -- Doug N3DAB/WPRX486/WPJL709 Rick Szajkowski va3r...@gmail.com wrote: = its not a voted system .. the repeater is a Harris Radio Phone repeater and I was looking at a Ge Phoenix VHF to UHF to the repeater site UHF phoenix to the controller again just to help cover the HT's in town ..

Re: [Repeater-Builder] Reed vs. Reedless Boards in Mitrek Radios
With the reedless board chip being nothing more then a simple resister network, I wonder what your purity results might be if you built-up a 127.3 network using 1, 5,and 10% 1/8w resisters for comparison as well. -- Doug N3DAB/WPRX486/WPJL709 Eric Lemmon wb6...@verizon.net wrote: = I recently acquired a Kenwood HM-250 Audio Distortion Analyzer, and I have been experimenting with various CTCSS tone encoders to find which produce the purest tones. Since I am putting together a 6m repeater using Mitrek radios, I wanted to compare the older HLN4020B reed board to the newer HLN4181A reedless board. What an eye-opener! At the outset, my gut feeling was that the reed board would produce a purer tone than the digital reedless board, since the reeds are essentially tuning forks. That turned out to be a false assumption. With two known-good tone boards hooked up on the bench, the 4020B reed board consistently produced a 127.3 Hz tone with distortion ranging from 0.75% to 1.52%, while the 4181A reedless board produced the same tone with only 0.43% distortion. I adjusted the output level pot (R23) on the 4181A board to match the output level of the 4020B board. I tested the 4020B board with six 127.3 Hz reeds. Another interesting fact emerged from my experiment: Although the PL tone reeds can be plugged into their sockets in either of two positions, I found that there was definitely a difference in the amount of distortion produced. The differences ranged from 0.1% up to 0.6%- not much, but surprising, since the reeds are supposedly symmetrical. I got similar results with KLN6209A, KLN6210A, and TLN6824A reeds. For comparison, I measured the distortion at 127.3 Hz from several pieces of test equipment, with the following results: HP 204B Audio Generator: 0.24% Motorola R2600D Service Monitor: 0.26% Wavetek 188 Audio Generator: 0.19% CSI TE-64D Tone Generator: 0.76% My next step is to evaluate the purity of the CTCSS tones after passing through an RF link. Some radios- cheap ones especially- use rather coarse tone synthesis techniques to generate PL tones, and the resulting tones are prone to falsing and talk-off problems.

Re: [Repeater-Builder] Suggestions on UHF - TXRX BP/BR dups
Robert, There is nothing wrong with the T-1504 series duplexer if it if properly tuned and adjusted, and unless you have money to throw away to bolster our sagging economy you arn't going to accomplish a lot in the process. I just retuned a set of 1504A's the other day for 443/448.325 and got 80 DB of isolation from each side, with an insertion loss less then 1.5 DB. Interconnect cables are easy to make for the 1504's and the service manual indicates the proper length of each cable for the freq. range you want to tune to. It's a lot easier and less expensive to add additional cans for greater isolation or filtering to the duplexer you have then puchase a brand new duplexer. Let me know if you need some help with this and I'll see if I can work something out with you about getting together after the Holidays. Doug (in Jasper, Ga.)

If your getting 75W+/- out of it now that is probably all you will get trying to move it out of band 20 to 25 mhz.

This will work, however use a low power setting on the radio and a low power slug in the watt meter. Also, tune each can on a side independently first, then connect the 2 cans with the jumper cable and retune the cans together. If you are changing the tuned freq's. drastically you can refer to the T1500 series manual found on the RB site and make new jumpers cables for your cans based on Motorolas charts. I belive the high side jumpers are slightly shorter then the low side.

Is there a trick to it that I don't know ?? Your idea about re-using an old harness from the top off of an antenna for the lower half of your dual makes sense. If you're using type N connectors (either crimp or mil clamp), the goop isn't a big deal, just crimp/clamp the braid with the goo on it, it will still make solid contact and help maintain weatherproofing. If you really want to get rid of it, use a solvent. TCE seems to work, available as LectraClean from CRC (available at Home Depot et al). --- Jeff

RE: [Repeater-Builder] DB antenna question
Thanks Jeff. OK, idea 1. and 2. are basically shot down in flames. Idea 3. I can handle. Again the question, if I use the original harness how do I terminate the connector where the lower section joined the upper. Just weather proof it ?? Answer to your last comment is no All my antennas are mounted on 2 GI pipe, bracketed to the side of the house, that run from the ground to approx. 5' above the roof line (25'+/-). My site is my house located on top of a small mountain (2750'AMSL) roughly 1000' above average surrounding terrain. I also have covenents to deal with (no towers). Average coverage has been approx. 40+ miles where not blocked by higher terrain from my NW to NE. Roger on the gravity connection bit on the 2 have but a 3/8-1/2SS bolt thru the joint would solve that problem. -- Doug N3DAB/WPRX486/WPJL709 Jeff DePolo [EMAIL PROTECTED] wrote: = 1. Mounting the dipoles and harness from a UHF DB420 on the same mast as a VHF DB224, or vice versa. (UHF and VHF antennas on the same mast) There will be a lot of interaction between the two. I wouldn't do this. You'd also likely need extra filtering on the ground between the VHF and UHF repeaters since the coupling between antennas will be very high. 2. Mounting the dipoles and harness from a DB420 on the same mast of an existing DB420.(2-DB420 UHF antennas on the same mast) Really bad idea. At that point, you may as well just use one antenna and a combiner/multicoupler at the bottom - you'd likely need almost the same amount of filtering with the two antennas separated on the same mast because there will be so much coupling. 3. Taking an existing DB420 antenna and feeding the upper and lower halves with separate feedlines to make 2-6 Db antennas on the same mast. The lower harness section would be replaced with with the upper harness section from a junk antenna. Better idea. This used to be order-able as a DB420D, which was really two DB408's on the same mast, one stacked above the other, with the feeders for both antennas terminating at the bottom. The isolation between antennas was something like 30 dB, so again, you'll still need adequate filtering downstairs. If any of the above ideas are practical this would allow me to recoup some additonal mounting positions or at the least reduce the clutter of antennas I have now. Can you mount two antennas on the same mount, one rightside-up, and the other inverted? If you do this, be careful if you invert-mount a DB420. The mechanical connection in the center relies somewhat on gravity to keep the two halves together; if you invert-mount, gravity is working against you. --- Jeff WN3A

Re: [Repeater-Builder] UHF Repeater Antenna Discussion
My 2 cents worth. Many years ago I had a 200' run of LDF5-50 installed by a professional on a 900'tower (rptr at 700' antenna at 900') about a week later we noticed that the TR performance dropped considerably. Personal inspection revealed that water or condensate (about a teaspoon full) had drained down the cable insde the hollow center conductor and had seeped around the inside of the bottom connector. The solution was to completely remove the connector and center pin, drain the cable and let it thoroughly dry then reinstall the connector. I never had another problem with it after that. I suggest you take a look at yours. Years later I ordered 2 runs of LDF4-50 w/ connectors installed from DB and after receiving them checked them for continuitybefore installation. One cable showed a direct short between center conductor and ground. I removed both connectors and found one connector had been improperly installed at DB. Apparently the portion that has the spring fingers on it had been allowed to turn in the tightening process and it had grabbed the copper shield, shredded it and bent it inward to where it made contact with the center conductor. Needless to say ,but I then removed all the other connectors to verify their condition and reinstalled all of them properly. A third case similar to the one above (shredded shield ) but no physical contact (no continuity) showed a 1:1 SWR on Xmit but caused the RF to desense the rcvr. to the point where the perfomance of the rptr. was drastically reduced from what it should have been. Similar to what you are describing. While you might not see a direct short or even an indication of high reflected power when you test the system, if you have any contamination, moisture, or metallic debris in side the connector it can cause you the grief you are describing. Hope this helps some. -- Doug N3DAB/WPRX486/WPJL709 Cort Buffington [EMAIL PROTECTED] wrote: = Don, two completely different antenna and feedline systems.

Two antennas connected to two feedlines which can either be terminated to the duplexer as you so desire? Only one feedline to one antenna, not coupled or combined in any way? One hardline / antenna works good (DB420) and one hardline / antenna (Telewave ANT450F10) works bad? The first step is to verify the Telewave wattmeter. I'd get a hold of a Bird 43 or equivalent and verify your readings. That's the easiest thing to do. If your forward / reverse numbers are accurate then I'd suspect the Telewave system or it's hardline, unless proven otherwise. You need to rule out either the antenna or the hardline by substitution, and one at a time. Possible issues could be bad connectors either at the antenna base or duplexer termination. How long ago was the antenna system put up? Was there some heavy rain in the area that water could have been introduced into the connector / hardline if they weren't properly water-proofed? Unless someone contradicts me here, I'm having a hard time believing that the vertical alignment of the Telewave is critical. In re-reading your post over a couple of times I'm wondering when you checked the alignment and then implemented a little down-tilt you may have done something wrong to cause the hardline / antenna system to react that way.

I agree about the painting. I don't see where you can get into any problems as long as the connectors, tuning shaft and loop slides (and slots in the cavity walls) are masked off. As for the 3 megs thing, remember a few years back where I had problems with a newly acquired T1504A that wouldn't quite make the 5 meg notch? It turned out that someone had repaired a notch loop and left a very large solder fillet that effectively made the loop electrically shorter. I cleaned up the eccess solder and voila! 5 meg notch once more. So my thought is that the coupling and notch loops are longer on a 5 meg split one than a 3 meg.

You could transform 50 UP to 100 via a 75 ohm odd-quarterwave cable. The length of the 50 Ohm coax going from the tx/rx to this antenna input does not matter for SWR or impedance. Only concern would be length and loss of 50 Ohm cable. Just to be clear, the length of the 50 ohm cable doesn't matter at the input to the antenna, but it DOES matter within the harness itself even if the cable isn't being used as a transformer.

Re: [Repeater-Builder] Desense Problem on 222 MHz Repeater
Couple of thoughts from one who is not to technically oriented. 1. Have you tried putting any notch filters between the duplexer and rcvr. to notch the TX freq. ? 2. Have you checked all of your cables and heliax connecters for proper installation ? I only ask this because I was having erratic performance and desense on a 440 rptr. and found some bad duplexer cable connector installations when I started wiggling and moving them around. Another time while checking Fwd/Ref. power and SWR on o 160' peice of 1/2 heliax that I thought was good (and getting satisfactory readings on my Bird mtr.), I pulled the connectors of each end to inspect them. I found one connector had been improperly installed, the heliax shield had been twisted inside the connector to the point where it was almost touching the center conductor. Even though there was no direct contact between shield and the center conductor the RF on xmit. was desensing the rcvr. when the xmtr. keyed up. Reinstalling the bad cables and connectors solve the desense problem for me. -- Doug N3DAB/WPRX486/WPJL709 Stu Benner [EMAIL PROTECTED] wrote: = Our group has substantial technical knowledge and experience, but we've been just about beaten down by a problem with our repeater.

With the duplexer terminated into a load, we have about 1 dB degradation in sensitivity when transmitting. However, with the antenna connected to the duplexer, we experience in excess 15 dB of desensitization. We have eliminated other narrowband transmitters and analog TV transmitters as contributing factors. We are left with a channel 12 digital TV transmitter at an adjacent site as a key contributor to the problem. Our hypothesis is that we have broadband IMD products from the mix of our transmitter and the DTV transmitter that are appearing in and near our receiver passband. Is it a rusty bolt problem or is there some other non-linear component somewhere on the site or in our system that is the mixing point - we don't know.

Narrow band is only required on the interstitial channels (those that fall between the repeater pairs) along with the reduced power requirements, but I don't believe the FCC would have any problem if were were to narrow band a repeater.

Once tuned per the manual, the TKR-750 will meet its specifications. There are several Kenwood dealers on the Repeater-Builder list who will gladly work out a deal for you.

Can any one point me to a mod. page or funish info as to how they succesfully modded there Q2220E for operation in the UHF band. I assume the loops and harness would require modding but have no idea about the tuning rods, capaciters or the aluminum extruded cavities. PS : I also posted a noted asking about a source of Motorola T1500 series passband coupling loops (.5 to 1.0 dB IL). I'm just looking for the loops but will take complete can(s) if they are reasonable. Thanks Doug N3DAB Yahoo! Groups Links No virus found in this incoming message. Checked by AVG Free Edition.

Re: [Repeater-Builder] Re: CSI -32 info for the group (SOT)
If I'm reading the manual that came with my original CSI-32 correctly it has a pair of Zicor XD2212 chips (U-18 an U-19). Been to long ago to remeber what was pulled to copy. Bear in mind I'm not an elctronics whizz, the problem has been resolved for my Ham friends, and I try not to use secret codes in the first place, that I know I'll forget or misplace. I'm a devoted KISS advocate. Doug -- Doug N3DAB/WPRX486 skipp025 [EMAIL PROTECTED] wrote: = Hi Doug, Does your CSI-32 have the zero-power (single chip) nVram or the pair of xicor nVram chips?
