Re: [Repeater-Builder] Can a Master 3 narroband
Hello Jim I note your message about narrowbanding and the comment about the MSR2000. I have seen no info on doing so but it seems to me that the MSR200 could be narrowbanded. The MSR is very similar to the Mitrek and it can be narrowbanded by using a kit by a company that slips my mind. Therefore I feel narrowbanding would be possible. I will be attempting this in six months or so. 73 de Tom Manning, AF4UG - Original Message - From: Jim in Waco WB5OXQ To: Repeater-Builder@yahoogroups.com Sent: Friday, August 27, 2010 10:07 AM Subject: [Repeater-Builder] Can a Master 3 narroband I have a uhf master 4 that has been used for years as a paging exciter.

Re: [Repeater-Builder] DB224A new harness
Hello Allan
As you note it would take a good deal of work to go from 154 to 220Mhz.
Yes the loops would have to be shortened and the harness would have to be be
reworked-shortened. This would be easier than changing to 144Mhz. I have done
this twice in the past. 73 de Tom Manning

I would certainly be interested in knowing just how a 150-162 MHz DB224
could be "easily be modified to cover 220". The dipoles would need to be
physically shortened and the matching harness would need to be completely
redesigned.
What magic do you have in your bag of tricks to manage this?

Hello Andrew and Norm
If you are trying to figure out the lengths needed for 144-148Mhz
I can measure what you need to know but not in a hurry. I have a DB products

about 10 years ago. What I need to know is the measurements for 220Mhz. I
also have several DB224a's that have been removed due to problems. These could
easily be modified to cover 220Mhz. 73 de Tom Manning, AF4UG

The unknown coax type is/was VB-83 (35 ohm). The VB-8 is of course
50 ohm and the VB-11 is 75 ohm.
I hope that is the info you needed. It would be great if you could
figure out what the open stub is for and can we use that for adjustments. If

I got the harnesses at no charge from Andrew. I contacted customer
support and told them I had 3 fairly new DB224's (2 a models and a b model)
that had water intrusion/contamina tion in the harness where they were
supposedly seal by the factory. I offered pictures and they accepted. Upon
seeing the photos they asked that I give them serial numbers and requested I
send the defective harnesses to them. I did and they offered and I accepted
replacement harnesses.
The two db224's that I have (personally) are the A models. The B
model belongs to my shop. I often end up with abandoned and or defective
db224's and other antennas as I work for a two way land mobile dealer/shop.
Unfortunately, I have yet to get any DB224e's or any DB304's, just tons of
DB224a's and an occasional DB224b.
Hats off to Andrew for shipping me free replacement harnesses. I am
still gonna ScotchKote those moldings regaurdelss.
If you look at the attached photoes from my initial post, you will
see that the open 25" VB-8 (50 ohm) stub is 12.5" from the "T" where the top
half and bottom halves of the harness come together, down the main feed to the
hardline (or whatever you feed the antenna with).
Last night I connected the Sitemaster up again and I noticed the
the SWR will come down some when I firmly secure the harness to the mast with
the metal tape. How far down remains to be seen. I will keep you posted.

Re: [Repeater-Builder] Converting a Range 2 VHF Mitrek to Range 1 (WAS: Holiday Special...)
GOOD AFTERNOON kEVIN This last response is my thinking about the Mitrek and is why I asked the question earlier. If the Mitrek coils are the same as the Micor coils what factor would prohibit this being done. There is considerable work to change the coils but if the Micor coils are the same nothing would prohit a person from doing this. As I said earlier I know for a fact that the mid band receivers will not tune lower than 146 Mhz. Perhaps an occasional one would be found that would tune to 144.0 Mhz but not all.

Re: [Repeater-Builder] Holiday Special - MICOR 2 meter receiver conversion from W3KKC
Hello Kevin Thanks for your reply. Your statement is correct in that all of the receiver coils begin to tune at the bottom of their travel. I have even tuned two or three too far and they dropped out with the resulting work to retrieve the screws. When tuned as best I can for sens the s/n ratio is 1+uv at 12db sinad. The original frequency sens was less than 1uv-usually about .3uv for 12db sinad. Replacing the coils are about the only solution I know of for these high split VHF units. I have in the past replaced two sets of receiver coils with Motorola coils and found I have good sensitivity as before modification. The transmitters all tuned well on this split and gave rated or more power output. The Mitrek coils looked very much like the Micor coils. I have replaced probably a half dozen Micor receiver coils proscured from Motorola in the past 20 or so years.

By that do you mean they won't make book specification on any frequency below 146 MHz? If that is the case, I would believe something is wrong. I have seen many Mitrek high-band receivers that were tuned for 144 something and had very good sensitivity. Let me ask you this When tuned at 144.89, is the front-end tuning all "one ended", or is there adjustment to spare? In other words, can you tune the front-end without the fear of the tuning screws falling into the casting? If you have room left to go lower in frequency, then the front-end is not the problem, and you'll need to look elsewhere for the lack of sensitivity. Another question - do these 4 or 5 units tune and make book spec sensitivity on their original high-band channel? I guess what I'm saying is I doubt the problem is the front-end helical resonators, but if there is a need for a conversion I'm not opposed to looking into making a modification available, if it is needed. If there are others on the list that have had good luck with the Mitrek on frequencies below 146 MHz, please chime in and let us know what you have and how well it works.

I use the connectors from MSR 2000 modules that I would not be using to go on the Micor modules. This is very helpful to save several dollars. 73 de Tom MAnning, AF4UG - Original Message - From: Kris Kirby To: Repeater-Builder@yahoogroups.com Sent: Wednesday, February 06, 2008 12:25 AM Subject: [Repeater-Builder] Micor station modules?

Re: [Repeater-Builder] crackle in a repeater tower
KE4ADV What you propose should be practice and not an experiment. It is just good practice to ground the antenna mast, coax and equipment to a common ground. Otherwise where I am located in West Florida the setup might last a month due to lightning. You should also use double shielded coax or hardline for your coax run and in your equipment. 73's de Tom Manning, AF4UG - Original Message - From: [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Wednesday, March 22, 2006 8:33 AM Subject: Re: [Repeater-Builder] crackle in a repeater tower I am observing the same phenomenon on a 2 meter repeater in my area. You'll find it interesting that the BD-224 was just replaced, however on "windy days" the repeater sensitivity gives way to that crackling noise that you referred to.My theory, which will be tested soon, is that due to poor grounding static charges build up in the antenna due to the effects of high velocity wind. Our plan is to install grounding kits on the coax at the antenna and on the ground near the gas tube. All grounds will be at the same point as much as is possible.Stay in touch with me for the result of this experiment. YAHOO! GROUPS LINKS Visit your group "Repeater-Builder" on the web.

Re: [Repeater-Builder] Repeater heard on Aviation Channel! HELP
Matthew I hesitate to make the statements I am about to make. I worked in the aviation field with FAA for 40+ years and have seen several problems you are having. One of the hardest to find was caused by a corroded pipe joint in an antenna mast. There an FAA freq was mixing with a commercial FM station and FM music was being broadcast to aircraft in a 25 mile radius. We solved this by using a DF and looking for the source. We could create our problem just by keying the FAA freq If as you are saying the repeater is being heard by aircraft then something is converting the repeater FM to aircraft AM. There is a possibility the aircraft radio is slope detecting the FM. Wish I could be of more assistance. 73 de Tom Manning, AF4UG - Original Message - From: Mathew Quaife To: Repeater-Builder@yahoogroups.com Sent: Friday, July 08, 2005 9:30 PM Subject: Re: [Repeater-Builder] Repeater heard on Aviation Channel!

Re: [Repeater-Builder] Re: Strange Desense issue on VHF Quantar
Andy You do not indicate what type power supply you are using. This sounds to me like you are using a switching supply and what you are seeing is spurs from this supply. 73 de Tom Manning azandyca wrote: I am usinga Motorola R2670 to look at the spectrum. I can see this at the RX port on the duplexer. Note that when I plug thing directly into the service monitor or replace the antenna with a dummy load there is no issue with the transmitter or receiver so it is definatly an external event. I also noted yesterday that this seems to be a series of 5 spurs right at 200K apart going down in frequency (no high side probably due to the reject side of the cavities). They are equal in strength at about -80dB. I have no other emmitters in the neighborhood I am aware of so this is strange. I am suspecting it could be related to the many megawatts of hdtv transmitters on the montain about 4 air miles away so I am going to try a DCI filter to eliminate any out of band signals from reaching the repeater today.

Is this mystery carrier present all the time, even when the Quantar is not repeating? All of my Quantar service manuals are at my office, so I can't study the possible leakages from the repeater until Tuesday, but I wonder if this mystery carrier is leaking out of the repeater itself. Are ALL shields in place and secured with every screw required? Are all components of your repeater grounded to a known-good station ground?

Re: [Repeater-Builder] Re: A Good 440 Anttena
Skipp This type antenna setup is of interest to me. We have our repeater antenna atop a 150 ft water tank but the cell antennas have taken over. The owner told us we would have to live with the cell people as they were paying customers and we aren't. My idea is that we could use four yagis around the rails with the power divided into four equal parts with the yagis fed in phase and get somewhat a round radiation pattern.

Re: [Repeater-Builder] DB224 VSWR Readings
Mathew Our club ran a DB224 for about 5 or 6 years until Ivan came along. We started with a gift DB224 which was inoperative due to a shorted harness. We modified the elements to 37" long by adding aluminum pieces which we heli-arced. Then we ordered a new harness for the two meter band and when received we repositioned the elements and dressed up the cables. We then checked the VSWR and found to be about 1.1:1 at our operating frequency. The Antenna was then installed atop a 150 Foot water tank. This antenna gave very good service until Ivan came calling. Ivan bent the antenna at a 90 degree angle and the VSWR went up to 2.2:1. Our previous repeater antennas lasted from 2 months to 6 months and were destroyed by lightning. I talked to a Cushcraft Engineer about our problem and he suggested we remove the antenna every time a lightning storm came and put it under someones bed to prevent damage. Our cost for the DB2234 we modified was less than $175. 73's de Tom Manning, AF4UG w9mwq wrote: >I am curious to know what others have resulted from changing the >elements and harness to the ham band as far as SWR and impedance.

Re: [Repeater-Builder] DB224 Element Impedance Info Needed
Charles, wd5eeh I read what you said about the 90 ohm load resistors built into the DB224 and will have to disagree with you. I have worked on many DB224 antennas and modified several and I can assure you there is no 90 ohm load resistors built into the harness. The harness is built of several values of coax to match the 100 ohm folded dipoles to a 50 ohm feedline. I suspect you will hear from others who also know better. I can safely tell you this is about the best antenna design I have ever worked with. 73's de Tom Manning, AF4UG Chuck Kelsey wrote: > Resistors That's a new one me. > > Chuck > WB2EDV > > - Original Message - > From: "Charles Miller" <[EMAIL PROTECTED]> > To: > Sent: Monday, June 14, 2004 11:37 PM > Subject: Re: [Repeater-Builder] DB224 Element Impedance Info Needed > > > The problem that you will find is the coax is not 50 Ohm or 75 Ohm.

We have a converted recycled commercial db224 which has been up 5+ years on top of a 150ft water tank with no maintenance required to date.

Re: [Repeater-Builder] Min FREQ Separtation, VHF rep, No Duplexers
Tom I think if you took two Mitrek units and set one up as a receiver and the other as a transmitter, using two antennas and two feed lines with 600Khz separation and kept the transmitter power at 20 watts or less this would work like you want. In my past memory I once saw this done. I think if you study the specs on the Mitreks you will see this should work. The selectivity of the receivers would allow this if the power was less than 20 watts. 73's de Tom Manning, AF4UG Virden Clark Beckman wrote: > You know I was thinking of any possible way this might work and I > remembered something after a club meeting last night, if both antennas > were covered with a globe of shielding foil except for 10 degrees facing > opposite directions, 10 watts of output with a 100 ft. long rg-58 > feedline extension, if all the users were in between the antennas it > would work within one 2.0 meg of split and this would work for a family > picnic or a hamfest flea market as long as there was no co-ordinated > repeaters using the same freqs.

Re: [Repeater-Builder] Is there a relationship between 147.225 and 146.925?
Michael This seems to me to be a classic case of RF mixing from one transmitter into another. The cure for this is to install a circulator/isolator in each feedline. The circulator does not allow RF from one transmitter to feed back down the coax into the other transmitter. I have measured RF fed from one transmitter back down the coax to another to be in excess of 5 watts on a 50 watt transmitter. This is one of the problems associated with having more than one VHF transceiver located on the same or adjacent tower. I wish you the best of luck in curing this problem. 73's de Tom Manning Pete B wrote: > Sounds like front-end overload to me.

Re: [Re: [Repeater-Builder] Motorola Motrac Radio]
Ken I think you have been around as long as I (40+ years in electronics). There was a line of transistorized modules that took the place of tubes. I cannot remember the type numbers or manufacturor of them. I have used several meters that had been changed to transtubes such as the H.P. 400D voltmeter. I remember there was available a set of replacements for all the miniature tubes in the Collins KWM-2. The advantage of the transistorized replacements was lack of constant changes due to cathode emission and thus lengthened the time between calibration checks. 73's de Tom Manning, AF4UG <[EMAIL PROTECTED]> Ken Arck wrote: > At 09:17 AM 3/23/2004 -0800, you wrote: > >Just before the transistor, solid state tubes.

Re: [Repeater-Builder] Re: Z Matcher
Eric I fully agree with your assessment of the impedance problem except the dummy load statement. I have never seen a good quality dummy load (Bird or other similar quality) measure anything like 50+-j86 ohms. I have seen some Heath cantennas read more than 100+-j ohms impedance. About the worst Bird I have seen is 75+-j20 ohms and this was sent back to Bird. Generally if a good Fluke digital meter reads 50 Ohms at DC the frequency response will be very close to that up to about the upper usable freq level. This observation if from 40+ years using dummy loads all over the world from many manufactors. Tom Manning, AF4UG <[EMAIL PROTECTED]> Eric Lemmon wrote: > Laryn, > > Go to the head of the class!

Re: [Repeater-Builder] To tune into a dummy load or the antenna...
Adi Did you consider the fact that your dummy load might have departed from 50 Ohms resistive? I have seen several dummy loads that read 100 ohms or more. Seventy ohms is very common. This is even for some high priced Bird loads. You can check a dummy with a good digital multimeter. A good dummy should read 50 ohms from DC to at least 500 mhz. You can also use a MFJ 259 antenna analyzer to check your dummy load impedance as well as your antenna and your duplexer. Good luck.
