[Repeater-Builder] schematic needed - OT
Gents I have a federal signal director model siren in my 70's TV police car that I use for shows etc. The siren works ok (hehe) but the PA sounds terrible. I suspect a bad mic. Does anyone have a schematic or a source for the service manual for this unit? Thanks in advance Ian R. VA2IR
[Repeater-Builder] Re: schematic needed - OT
I will post a pic, however the director model had a central switch with 4 positions, an on-off volume switch on the right hand front panel, a manual siren button on the left had side of the panel, and the mic and fuse holder are on the bottom of the unit. THe outside of mine is painted beige. As for a replacement mic, living here in Canada, where men are men and women make the igloos, for a $20 item by UPS, the UPS guy will ding me for $100 just in brokerage fees, and taxes on the fees, and then taxes on the taxes for the fees... I have a wall full of mics - I'm sure one will work. Ian VA2IR --- In Repeater-Builder@yahoogroups.com, Mike Morris WA6ILQ wa6...@... wrote: What' s the model number?

[Repeater-Builder] Re: Interfacing our repeater to skype or other VOIP client
Thanks for all the fast replies. The only hitch in my idea is finding a voip or voice client for the blackberry that is not designed to make cheapy phone calls, but that can work like a walkie talkie, either full duplex or half duplex. Any one know of a blackberry app that can work like that? Skype for the blackberry has to work thru a desktop like a remote.

[Repeater-Builder] Cable lengths - critical?
Hi guys. We finally secured a brck type UHF amp for our hamtronics machine. The Hamtronics puts out 7 watts after all the filtering into my Bird Termaline wattmeter. This needs to be knocked down to below 4 watts so as to not over drive the outboard amp. I had 2 options - one is to insert a pass-can into the TX line before the new amp. I have one at home. Tuned it to the correct frequency and it has an insertion loss of about 3db or so. The other suggestion from Hamtronics is to drop the V+ to the internal PA of the repeater to 11 volts or so (I can insert 3 or 4 diodes in series with the V+ to the PA to do this). But , in any case, we will need to make 2 patch cords. Is the length critical (i.e. electrical 1/4 wave or odd multiple thereof) work or will any convenienient short length work? We have some 9913 for this. Also, the way the repeater is configured right now, at the TX port of the repeater (before the filtering) there is a circulator. Should the circulator now be installed after the outboard amp? Or leave it where it is? Thanks. Ian VA2IR VE2RMP Repeater Group
[Repeater-Builder] GE Nomenclature
Hi guys. THanks to all who looked up those transistor numbers. One more P I T A question. Our club received a Exec II base station with the folling combination: F156KAU66A TX: 124-A RX: 89-1 I did try to search this on google with no result. Does someone know what this is? We were told its on UHF - I havent had a chance to see it yet. Thanks Ian VA2IR

[Repeater-Builder] MSR-2000 UHF question
As as addition to my question a few posts back, I have this MSR-2000 amp. It is the medium duty model and is very clean. I see from the PDF file on the website it needs 13.8 and 9.3 volts for the control board. There is a 3 pin male recepticle on the inside rear of the unit, which I believe is the interface to the rest of the MSR repeater. Is this where I apply the 9.3 volts as well as +13.8VDC? I did try this with no luck. Ran thru some of the tests outlined in the PDF file and it seems ok. But feeding in 200mW from my HT does nothing, and I went right thru the UHF band. I got this off of Flea bay so most likely its a very expensive boat anchor. ANyone done this before - converted this amp to stand-alone application? Thanks Ian VA2IR
[Repeater-Builder] MSR 2000 UHF amp
Hi guys Need a little help. I picked up a clean amp for our UHF machine. Its an MSR2000 amp (same as the pics in the scanned PDF file). However, this main board only has 3 transistors on it - one small driver and 2 of the flat white power transistors. There is also a controller board. The fellow who sold it to us said it was a 30 watt unit. The tech document on the site shows a 85/100 watt unit. I guess the Big M made several different boards/styles to fit custom applications. The corresponding model numbers from the website are not here. I find stickers that say the following: VLE1052A and VLN1064A I'll download and print that tech document, but I wonder if any one has some quick info to make this a straight in-out amp for our UHF repeater. I think I can bypass that controller board, unless it is absolutely necessary. Thanks Ian, VA2IR VE2RMP Repeater group
[Repeater-Builder] UHF repeater amp wanted
Hi guys, Our club is looking for a small repeater amp (50 watts max) for our UHF machine. Right now its putting out a whopping 6 watts - we did a test with a 25 watt strip off a TAD-450 commercial rig and the listening station reported a significant gain. The signal went from 1 s unit on his rig to 8 s-units. I am wondering if any of the GE or Motorola final strips are good enough to handle the duty cycle. The little TAD unit I tried briefly worked, but I'm sure would burn out in short order. You can contact me off list at va2ir at securenet dot net Thanks Ian VA2IR VE2RMP Repeater Group

[Repeater-Builder] Re: UHF repeater amp wanted
Cool - I will separate the PA from the radio and see if I can get it going. Someone did post the various functions of the wires that go to the main board. The repeater is in a small radio shack (good name for a store, no?) in the woods - no heat at all so the winter should not pose any problems for cooling. I can get a couple of good 120V fans to cool the heat sink. Worth a shot. --- In Repeater-Builder@yahoogroups.com, Gary Glaenzer [EMAIL PROTECTED] wrote: with decent air-flow over the heat-sink, probably I don't recall ever seeing a PA on ANY Maxar fail driver transistors, yes PA's, no - Original Message - From: Ian Miller To: Repeater-Builder@yahoogroups.com Sent: Wednesday, October 22, 2008 10:25 AM Subject: [Repeater-Builder] Re: UHF repeater amp wanted I actually have a UHF PA from a MAXAR 80 that was used on 440.

Hi fellows. This is a little off topic, but lately I have been watching and taping the old EMERGENCY! shows on WRTN Buffalo on DISH Network. 4PM eastern. From reading on some fan sites, the dispatcher, Sam Lanier, who was a real LA County fire dispatcher, used a ZETRON Station control unit to send out those tones that were heard in the station, and opened the doors.

[Repeater-Builder] Antenna question
Our group has a Sinclair 8 dipole array for UHF. The repeater was recently moved, and has not been behaving as usual. It hears OK, but seems weak on transmit. One of the members went up to the site last night with an MFJ antenna analyser - and he measured SWR at 3:1 - with no real resonant point. Our old UHF beam that was on the same tower and same feedline had an SWR of 1.5:1 measured on the same analyser. Is this method of measurement on an 8 dipole antenna correct? We have not put an SWR bridge on it. For the moment the repeater is off the air until the antenna question is resolved. What is inside the guts of one of those 8-bay antennas? Do they have a weak point where a bad connection can occur? Thanks Ian VA2IR
[Repeater-Builder] maxar 80 uhf
Fellows I have a MAxar 80 mobile MD34tsa1800A sitting on the shelf here. Its a 25 watter according to the side plate. I'd like to make use of the PA section on our Hamtronics unit to experiment, to see if extra RF out will cause any desense. It looks pretty beefy on the heatsink for a trial run. Here is my problem. Aside from the small RF in and out cables, there are 5 leads that go to the main board. I will assume they are for B+ and some sort of TX switching. I dont need any TX switching as the amp will be in the TX line of the repeater. Has anyone got a wiring diagram for the MAXAR handy? I've looked on some manuals sites with no luck. Thanks Ian VA2IR
[Repeater-Builder] 440 MHZ PA - ideas?
Hello. Our club has a Hamtronics UHF repeater with the optional PA enclosed. It puts out a whopping 7 watts to a dummy load. Antenna is a Sinclair 8 dipole array. The repeater has been moved to a site 25 miles north of where it was. Although it hears well, it could use a little more oomph on transmit. I have at home what looks like a UHF PA from a Mastr 2. Goldish color, main transistor is a MRF646. Feeding in about 5 watts from an HT only got me 15 watts into the dummy load. I scoured the net looking for a simple UHF Class C design that I could transplant that 646 into. I cant even find the old Motorola data sheets that gave a test circuit. Is any company making a reasonably priced UHF PA? Or can someone forward me a circuit or a link to a circuit that I can try? Thanks in advance. Ian VA2IR VE2RMP repeater group

Hi Guys I dont usually post here often, but after 25 years in the same spot, our club's VHF and UHF machines have been taken down and being moved to new locations.
