RE: [Repeater-Builder] Mastr II mods and parts
In the link to the unit he bought off ebay, in the photo the GE Mastr II was the IDA equipped version. Doesn't have a card rack to plug the PSE into. Of course you could wire it in, but not as convenient as having the original style card rack where you just plug it in. Ralph W4XE --- Duplexer? Nope, didn't say anything about a duplexer.

RE: [Repeater-Builder] Has anyone measured out-of-band rejection for a duplexer?
Tony, Our club ran some wideband plots years ago with a spectrum analyzer and tracking generator on a VHF db-4001 BP cavity and a VHF WP-641 BPBR duplexer. We were getting killed by the site's local TV station transmitter. Very discouraging results if you expect a BPBR duplexer to provide rejection beyond the tuned target frequencies. The band-pass db-4001 had a repeating pattern up the spectrum letting in several pass peaks, so you have to be careful there as well. I have a PDF of the test results if anyone is interested. We've had success adding extra BP cavities and a DCI filter on the receiver for high RF ambient sites.

Hi Everyone, Without the benefit of a spectrum analyzer, I would like to find out how much rejection of out-of-band signals can be expected from a typical UHF duplexer. Have a MSF5000 on 452 that works fine with the T4084 duplexers (1500 style), but have a lot of VHF data and FM broadcast hash that is trying to make it in (the 45kW FM is about 400 yards away and the VHF data is almost 1/3 harmonic). Looking at the documentation, I can guess its about 20db per cavity (or can), but the graphs don't extend very far. So for a regular four-can duplexer I might be providing 40db of protection. I want to increase this, and plan on adding one or two more cans on the receive side, and a Sinclair preselector in-between the latter two to make up for the increased insertion loss. Just wondering if anyone ever tried/measured this, or had ideas about filtering out FM broadcast. Eric mentioned using a single 7" Sinclair cavity, but I'd like to see if I can use some spare 1500 bandpass/reject cavities first. I don't think a 1/4-wave stub will work with that much field strength prying open the MSF's front-end. Thanks, Tony Yahoo! Groups Links
RE: [Repeater-Builder] Motorola Suitcase Repeater data need
The original M suitcase repeaters were MX based. The original standard MX was crystal controlled. Later MX-S radios were synthesized via a internal prom/eeprom. Specialized gear to reprogram those, but a few comm shops out there on the web that can do them. For the crystal UHF MX it works off one crystal for the frequency and another is the offset split. In the HT version there usually was a 5 MHz offset and a simplex offset crystal. All three are housed in 'channel elements'. If you are careful you can replace the crystal yourself. In the repeater there will be two MX's radios, one only populated with modules for the receiver and the other for the transmitter. So you'll have two xtals to get. I don't have a manual in front of me, but be warned that the 'modules' which make up the receiver and transmitter were range dependent. Usually the radio will work if you bring it down to the ham band, but it might not meet specs with the wrong modules installed.

RE: [Repeater-Builder] cos for delta radios
Wayne, A few questions to to ask first. Have you programmed up the radios yet or are you testing before reprogramming? Advise to test on commercial freq before programming to ham. Which model of Delta is this: the Delta-S or Delta-SX synthesized model? Do you have speaker audio wired up and working? Did you add a squelch pot if one isn't already installed in the radio? There are a number of sites showing how to hook up the radio without a control head. Are you using one of those websites as a guide? Most are slanted towards packet use which is slightly different than voice use (like the addition of a sql pot). You have to make sure you have all the power and grounds hooked up to the proper pins. Did you get the transmitter to work, audio & PTT? It's always easier to test it out initially with a head to start with. I'd highly recommend you try to find one somewhere, perhaps ebay if you can.

RE: [Repeater-Builder] Emergency Power
What power output level is the repeater station? The usual 110W? The 110W amp doesn't play well at lower power outputs. It tends to spur and the efficiency isn't great. I'd first thought about putting a relay in the PA to twiddle with the main power output pot setting. I DO NOT like modifying the stock gear so that idea was immediately thrown out. I thought about using a couple of small relays to insert a 50 ohm attenuator in-line with the exciter to PA connection to reduce drive level which would reduce output level. The relays could be run off a wall-wort for the power fail switch over. This was somewhat attractive with the RCA connectors from the exciter to PA input. They are readily accessible and the scheme is reversible to stock. Before anyone screams, I realize both of those solutions would lead to the problem stated above. You could use two antenna relays to bypass the PA altogether and run 250 mW barefoot with the exciter. Would be very low output, but would last a very long time on batteries. For slightly higher power with the two relays you could insert a much smaller output rated PA (perhaps a GE M II 40W PA idled down) after the exciter. You probably want make sure you don't switch out a PA to no load while it's outputting power. Perhaps wait until a PTT off time frame. Any decent controller with a macro could accomplish that. As a side note, we removed our continuous duty 110W PA for servicing one time and substituted a 40W intermittent PA idled down to 20W. I don't think anyone on the repeater even noticed. Another option would be to utilize a secondary lower power transmitter (GE Phoenix?). Switch out the GE M II tx audio/ptt from the controller to the alternate TX and use one antenna relay to switch the RF over at the duplexer. Again taking care not to remove a 50 ohm load from an active transmitter. These may not be optimal, but I'd also like to hear of other suggestions.

RE: [Repeater-Builder] Mastr II station cards.
These two cards plus the 10VDC regulator card are all that are needed to make a GE Mastr II station into a repeater. They plug into the card rack above the RF fold down deck. The repeater audio card processes the receiver audio (de-emphasis) and mutes on no signal. It looks like there is some sort of decoder plugged into it. Perhaps someone else can ID that part of it. There is normally an optional PL High pass filter that plugs into it to strip user sub-audible PL tones. The repeater control card keys the transmitter upon reception of a rx signal and does a hang timer. The enable/disable switch turns the repeat function on and off. However the control card has no CWID provision. Did the front of that say MARC V, it is hard to read? That would make it a piece of their early 800 trunk system.

In the M II station, the PL board next to the receiver mounted on the system board is usually for decode only. There is an open space next to the exciter for an encode only pl deck. You may not have that installed. They are a little harder to get ahold of. Another recent thread discussed the Comspec TS64M2 ? that is designed to drop into a GE in place of the regular PL deck.

The Moto Maxtrac & GM300 are also handy if you get the 16 pin rear accessory connector variant. However the moto will set you back significantly more $$.

On the other hand the Radio Shack receivers actually listen for the SAME turnoff code and act properly on it... they actually unmute the audio for the message, and remute it when it's done... what a concept. I was told that one guy modified the RS receiver to insert audio from an external receiver into its decoder section, but I've not tracked him down.

RE: [Repeater-Builder] GE Mastr II Station
Bill, I believe mine was setup as tone remote/rpt as well. Don't remember any muting problems. Do you have a manual on the IDA? I think its up on this reflectors website. If not I can email you a copy (1/2 meg pdf). I'd start at the receiver drawer first and look at what is going away on the receiver during TX PTT. The below signals are the ones that you'd want to look at first. J931-10 RX OSC CNTL J931- 17 RX MUTE J831- 18 RUS J904-1 CAS J903-1 RX F1 RXMUTE is related to PL detect, the RX OSC CNTL and F1 xtal control should be tied constant. You didn't say if this was a carrier only or channel guard unit? I have a sneaky suspicion if you have a stock GE PL decoder in the unit, its half duplex only. When you key, the pl decoder detects PTT and your CG decode goes away and then the RX unit mutes via RXMUTE. On the IDA, RXMUTE/RX1MUTE is H12 to H13 jumper, then there is the H41-H42 jumper on the GE M2 system board that ties the CG decoder boards signal back to the IDA. Once you get that figured out, the other external repeater controller mods should work for you. Drop me a direct email if you want to chat some more.

This is my first 'mobile' version, so time will tell if desense is an issue at ~50W half power rating output :) Just got it finished and cooking on the bench last night.

Now it's crunch time, as I need it on the air soon. I have a Mastr II with the IDA P52 controller. It is now working just fine, and I now want to add an SCom 6K controller to it. The complications start because I want to leave the IDA controller functional as a "bare-bones" controller and use the speaker on the IDA for monitoring at the site. The SCom will have the audio passing through it, so I will have to somehow stop the IDA from passing audio from the receiver to the transmitter. I plan on putting a toggle switch to break the PTT and TX audio from going to/from the IDA controller and connect these leads to the SCom controller. Other leads, such as COS and PL decode would be bridged. That way, I will have LED indications on the IDA and audio available at the IDA speaker for troubleshooting. If I want to remove the SCom controller, all I have to do is flip the switch and the IDA controller would be functional. Any ideas, suggestions? Anyone out there already doing this with the IDA controller? Maybe I'm just over-engineering this project. 73, Joe, K1ike Yahoo! Groups Links Yahoo!

RE: [Repeater-Builder] Id'ing receiver links
Glenn, I drop the pl tone on the link tx when there is no COS active. When the link controller (NHRC2) id's the link tx the main site voter rx won't pick it up unless there is traffic going because there is no PL. So this effectively filters out 'most' of the link id'ing without having to notch filter the cw id audio freq at the main voter rx. This requires you have PL on the link. At my noisy sites, this is a must. I dont flat audio pass the user pl tone. Its filtered out and regen'd. There are of course advantages to flat audio on voted systems but it usually requires more radio modifications to implement. I haven't read the moto voter system manual in awhile but I seem to recall it is similar to the GE system. In the GE, the local voter link rx encodes a 1950 Hz inactivity tone to the voter rack at the main site. When the voter receiver picks up COS/PL from the remote link tx it removes the 1950 Hz tone and passes the audio to the voter rack. The voter rack then starts voting that channel. The use of these signaling tones means you dont have to look at COS detect signals which is nice in a remote audio only wireline application. You shouldn't have to have the link tx up 24/7. FWIW some local guys dont ID their link tx, arguing its ID'd on the main repeater but thats stretching the FCC rules in my opinion. However they've gotten away with it for years. Your mileage may vary. With my luck I'd get a knock on the door from the FCC.

[Repeater-Builder] GE Exec II Chn element interchangeabliity
A friend has asked me a question about Exec II channel elements and isn't on this reflector. So I'll pose the question for him. I know that in a pinch the GE Mastr II ICOMS can be substituted somewhat for VHF/UHF, Low band maybe even? (couldn't find the exact thread on this). But, I don't think I've seen mention of the Exec II's (or MVP's) being able to swap a VHF chn (or 'crystal') element into a UHF radio or vice versa. Also what about the low band 50 Mhz? Since the Exec II version doesn't have the oscillator or EC/2C/5C business, perhaps they will swap around easier between bands. This is all of course assuming the 'proper' xtal is inserted for the desired freq of interest. thanks, Ralph W4XE Yahoo!

The new one is: http://www.alabamarepeatercouncil.org/ which Jim correctly gave you. The website has an online application you can download and send to Howard. I'd drop Howard an email telling him where the proposed repeater would be located. You'll find many areas of Alabama have no open 2 meter pairs available.

RE: [Repeater-Builder] Fan Temp Switch
For the fan application, you can purchase from digikey http://www.digikey.com/ over the web or landline a CANTHERM bimetal temp normally open switch which will close when the temp reaches the desired setpoint. Has spade lugs for connection. Remember to apply a dab of heat sink grease when mounting. They are in the $8-10 range. Note they are rated in degrees C, so you'll have to convert to degrees F to pick the right one!!! Heres a link to a java script: http://www.nomoreodor.com/celsius_to_fahrenheit_conversion.htm The part number will be 317-109X-ND, where X selects the temperature. The one I picked was 104 degreeF range if I remember right. Take into account the ambient temp range of the installation you are in when selecting the setpoint temp. A setpoint too low would keep the fan on all the time in an uncooled repeater shack in Phoenix AZ. 73's Ralph W4XE -Original Message- From: kc4wgh [mailto:[EMAIL PROTECTED] Sent: Friday, April 08, 2005 11:07 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Fan Temp Switch Back again.

RE: [Repeater-Builder] Linking Question
If the link requires PL, then turn off the PL when there is no COS from a user. (Many controllers can be rigged to implement this, or you can make a circuit to mute PL driven off COS gone). This dead hang time after a user lets up is usually when the repeater tries to ID. The distant repeater wont repeat it since it doesn't hear PL on the signal. However, normally if the link radio is established on a 'remote-base' port of both systems, the controller is usually programmed to not send ID audio down a remote base port, so no Id-overlay problem. 73's Ralph W4XE -Original Message- From: Tony [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 29, 2005 7:49 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Linking Question In my quest to learn about building my first repeater, I have thought of a potential problem.

thanks for the comments guys on PL encoding the old midlands. Its been a few years since I messed with them. Seems I remember I did something similar with cap/resistor tapped into it. Will have to dig them back up and see where I was trying to inject it. UHF 440 control/link pairs around here are drying up fast, so I thought I'd reuse these old radios and get some use out of them on 220 MHz.

RE: [Repeater-Builder] Re: 220 Repeater
While we are on the subject of midland/clegg 13-509 radios/repeaters has anyone had luck PL'ing the exciter. It wasn't setup originally for PL encoders. Initial attempt exciter+PL audio wasn't very promising with a TS-32. Looks like you'd have to FM the varicap directly.

RE: [Repeater-Builder] Help: GE M2 PL decode dropout on voice peaks and IDA control shelf
Hey Fred, Thanks for the reply. You must have missed the orginal posting. It's a stock GE digital pl encoder card. Swapped it out with another GE digital card and also a comm spec TS-64MII. Also swapped out the entire rx & audio boards. No difference between the two GE PL decks or alternate rx components. The TS-64 did seem a little better than the GE in decoding without talking off. Interesting point in seeing the lpf fail. Will probe around some more on the pl deck. Didn't get a chance to get back to it yesterday...ho ho.. Have a couple of things to try that were brought up earlier. 73's Ralph W4XE -Original Message- From: Fred Seamans [mailto:[EMAIL PROTECTED] Sent: Sunday, December 26, 2004 7:00 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Help: GE M2 PL decode dropout on voice peaks and IDA control shelf Ralph: You do not say what you are using for a CTCSS decoder.

RE: [Repeater-Builder] Help: GE M2 PL decode dropout on voice peaks and IDA control shelf
Thanks guys for all the comments. Yes, the one ht I normally use on the bench may be a little hot on PL (er I mean CG hihi) Dev and voice dev, but not way out of bounds. Kind of one of the reasons I use that one, is it's on the edge as a user radio might be. The point is, it's never done that with any other GE M2 on the bench before. Thus my questioning of the hardware under test. As for quality and standardization of radios, I agree. They are all over the place audio wise. Sure I could crack open this particular HT and turn it down to 200 Hz pl deviation and 4 KHz peak voice dev. I know if I put the repeater up on the mtn site today, some of my users will talk it off too. It would be hard to bench calibrate all the users radios out there. Again, I just think there is something in the hardware I'm missing. I did grab two other ht's as stated earlier and they created the same problem. One HT was a moto saber btw, so hopefully they did their homework correctly on PL injection into the transmitter audio chain. I dont remember the exact particulars on the Saber, but I remember it does have a lower PL dev and much lower audio dev. Still shuts the PL decoder down. I looked at the audio levels going into the pl deck. Didn't look out of whack. I'll try changing the PL tone from 127.3 to something lower that I normally use. That was a good suggestion and easy to try. Maybe I have one of those voices for 127.3. Someone mentioned supply voltages. The 12 VDC supply is the bench supply right now. I adjusted the 10 VDC a long time back when first starting with this 'new' repeater station. But, will recheck the 10 VDC, just in case. Well its getting late and Santa is near (for the kids). Thanks again guys, you given me some things to think about. best holiday wishes, Ralph W4XE Yahoo!

[Repeater-Builder] Help: GE M2 PL decode dropout on voice peaks and IDA control shelf
Working on an IDA control shelf equipped UHF GE M2 base/repeater. Normally used to working with a lot of the older card rack style control shelves. Never saw this happen on other GE M2 repeaters or mobiles. Here's the situation: I am using the repeater system looking at RUS for PL detect and CAS for COS. Either running repeater in stock IDA repeat mode, or externally wired RC-85 controller. Using an HT on the bench if I hit the audio hard getting close to 4.5 KHz peaks the repeater would shut down in PL mode (127.3 Hz FWIW). If I run in COS only mode, no issues. I had originally thought perhaps it was something in the IDA control shelf, since this is my first IDA equipped machine. Probing around saw that U7A 4066 in the IDA was muting the RX audio vol/sql hi to TX audio hi path. That control line leads to RXMUTE (amoungest other sources) which started me looking at the PL decoder. Used a pl deck extender card to isolate the PL deck's RXMUTE decode signal from the IDA. Its the decoder for sure, rxmute high (pl detected) on low level audio and rxmute drops low (no pl decode) on loud voice peaks. This is a GE stock digital PL decoder. Swapped in another ge pl deck. Same deal. Swapped in a TS-64MII and it also does it, but not as bad. I even went so far as to look at R608 audio preamp pot inside the shielded box on the audio/sql board. It adjust the VOL/SQL hi signal toward the pl detector. Its adjusted within limits and didn't make any difference. I swapped out the GE RX front end and audio/sql boards with known good ones just for grins thinking distorted audio. Not the problem. Rechecked the rx chn element freq using the F-11.2 trick on the service monitor. It's dead zero'd. This effect happens on several HT's on hand. Main 'test bench' HT measured 650 hz pl dev and 4.5 KHz dev voice peaks. Audio source, my highly calibrated voice 'Ahh 1 2 3 W4XE' hihi.. Now I can fully understand a real distorted audio signal or one that's way over deviated out of the receiver limits not being decodable. But, I can't ever remember being able to talk off a pl decoder on innumberable GE M2's I've had on the bench before. The only new variable is this IDA shelf and maybe the system interface board in the drawer. Haven't compared it to a card rack version to see if they are different. But, not much to go wrong on that system interface board in any case. Thought I'd throw out an email while everyone is sitting at home dreaming about sugar plums.. Has anyone else seen this problem? 73's and happy holidays Ralph W4XE Yahoo!
