RE: [Repeater-Builder] Repeater Help
Ok, the power supply and controller is probably doable, but no exciter currently. Oh well, I was hoping there was SOMETHING that could be done to repair this obviously poor excuse for a repeater.

Kevin K2KMB Here is what I'd do: (in the short term) 1.) Take the Spectrum exciter out and throw it away. 2.) This next step is optional: Smash it with a hammer so you never have any thoughts of reinstalling it. 3.) Install a used Hamtronics exciter in its place. 4.) Gut out the old control and power supply circuitry from the Spectrum. 5.) Install a NHRC-4 controller. 6.) Hook it to a Astron RS-35A/M power supply. (in the long term) 1.) Save some money. 2.) Throw everything except #5 and 6 away above. 3.) Build or buy a real repeater. No I'm not joking. Kevin Custer Yahoo!

Unfortunately Joe, everything for this project is being donated for an OEM/RACES project to improve county coverage, specifically because of the lack of $$. I also wanted a Mastr II (got one donated but upon further inspection was missing a board and the PA was toast.) or a Micor but unfortunately no one was able to donate one.

You may want to look into a Johnson 530 or 559 depending on which bandyou want. They are cheap at swap fests and very dependable, I usually buy them for 5 to 15 dollars. I have been running one on each band for over five years and zero failures. Don't get me wrong, I feel there is not much better radio than a GE Master II, I have several of them also but for ease of conversion and if high power is not needed you can't beat the Johnson.

All, I am doing this to try and get as close to total county coverage via HT as I can. There is another UHF machine at the other end of the county that I am going to link to via Echolink when we are deployed. I am also working on an incident reporting system that will use SQL as a back end and can be accessed via TCP/IP over RF and via the internet for personnel/resource tracking and assignment, scheduling, traffic passing and record keeping, etc, etc. Once completed I will be releasing it as freeware for other hams to use for RACES/ARES work. Let me know if anyone is interested in helping beta test and guide the direction/design of this program. The more, the merrier! :) Thanks again to everyone on the list! Kevin K2KMB Yahoo!

It's nice to see I'm not the only one with a problem. I'm glad that GE NEVER made an exciter board with a problem It too might get flamed. Some on this group don't know how to take a joke or fix serious problems. The problem with the Spectrum repeaters is that the designer( not engineer or design engineer)that designed the exciters designed things that looks like a CB'r designed it. After a very close inspection and some time spent thinking about the spectrum that I have I found a simple solution to the Tx problems that It has. Here are some serious suggestions. 1 remove the exciter board and replace it with the MASTRII exciter board. That'll fix that problem real fast. The only thing that you need to do is arrange for the necessary +10 Volts to operate it, even the least technical ham should be able to take care of that. As for the controller the SCR1000 has a controler connector on the back for a controller. All of the lines that you need should appear there if the 4000 also has the connector. 73 and good luck with your project.

RE: [Repeater-Builder] Apcor
The box on Emergency! was actually a GE telemetry radio I believe. The APCOR consisted of 2 parts. The APCOR itself was MX based and ran relatively low power, I think around 2 watts. The mobile unit was Micor based and they were strange beasts. The Micor/APCOR system was an in-band UHF repeater system. The Micor would TX and rcv on the med channels 1-10 on 460.xxx and rebroadcast out to the APCOR on 450.xxx. A neat system for its time.

RE: [Repeater-Builder] GMRS Repeater Info Wanted
Also Matt, since GMRS is limited to 50 watts, you can use a mobile type duplexer, like a Celwave/RFS 633 series, which I've seen for less than $100 on ebay, and have even seen some around $50. If you can get the mobile radios cheap at a hamfest, and a mobile duplexer cheap, you could probably set up a GMRS machine for less than $200, including crystals, if you use a crystal type radio, since you already have an antenna and hardline.

RE: [Repeater-Builder] GMRS Repeater Info Wanted
I was simply stating that trying to use mobile gear is an inexpensive way to do it. It is NOT illegal as long as the radios are type accepted in the first place, whether mobile or base. If you want to spend a little more money, then buy a Micor or Mastr II base, drop the power level down to 50 watts, and use that instead. GMRS has been around for MANY years. It is NOT a new service. And back in the 80's and early 90's MANY people took regular land mobile bases and mobile units and converted them to GMRS use. It wasnt illegal then and is not now. That is the point I'm trying to make.

A radio is certified for a certain service (part 90 or 95 or both). This radio can be used as a mobile, base, repeater, portable, etc, providing it meets the criterion for that application in it's particular service. Base and repeater stations in GMRS service are required to stay within 2.5 PPM, mobiles are only required 5PPM. Does this mean a mobile can't be used for base or repeater? No, only that by some means the frequency tolerance must be met. This is usually accompished by getting a 2.5PPM channel element for the radio. Some radios will maintain 2.5PPM by being kept in a somewhat controlled environment, such as a heated and air conditioned room.

I believe that stage would go down to .5 watt with no problem when turned down in RSS but I havent actually done it. It would be more trouble for me to modify the radio to run the PA right now than it's worth since it already covers out about 100 miles with the power level it's running.

OK guys, looking for some suggestions here. Has anyone used any commercial HT's as a TX driver for a repeater? And if so, what do you recommend? Where did you pick off your audio and PTT for the TX? The reason I'm asking is I am looking to use a Maxtrac as a receiver on 2 meters, which is fine, but I have a 100 watt continous duty GE Mastr II PA I want to use, and it only needs 400mw to drive it to 100 watts, so I'm looking at using an HT rather than trying to mod a mobile rig to TX that low a power. Any and all help appreciated. TIA to all! Kevin K2KMB Yahoo!

Can anyone give any input on how to go about hooking up the third radio to make it work properly?. This will be used for temporary installations only. Aside from the heat issue are there any other pitfalls or concerns I should look at for. These will be run on LOW power when being used to help with the heat. Thanks, Steaven, W4YI Hi Steaven, I have been playing around with the GM300s for a couple of weeks now with plans to use them as UHF link radios. In my humble opinion, they are a nice little radio and should do a good job. This, of course, will be proven or disproven in due time. Here are some of my observations: The heat issue can be a problem. Turning the power output down only adds to the heat problem. Instead, I took Kevin's (and others') advice and pulled and bypassed the final. The radio does about 3.5 watts this way. The output is very clean (I looked -70 dB and didn't detect a thing) and stable. I observed this into load with a 1:1 SWR as well as a 2.5:1 SWR. Aside from the (still) moderate heat produced, there were no detectable problems during a 35 minute keydown period. To overcome the heat issue, I simply added a computer processor fan to the back of the radio pair that triggers on from the receiver's COR (or tone squelch) and shuts off one to two minutes after the carrier or tone drops. (See Kevin's web site for the circuitry) My radios didn't display any significant drop in power until I tuned down around the low end of 433 MHz. The 16 pin connector has descriminator output, mic input, and PTT available on it making interfacing quite easy. The one drawback I have detected is the built in Tx delay. When added to the inherrent delay from an aftermarket tone decoder, which I am using on the VHF receiver married to this transmitter, the overall delay borders on the undesirable. I have a GM300 service manual and schematic en route, but without it I haven't determined a work-around. I suspect this delay is intentional and can be altered through minor component or circuitry changes. I hope this helps. Good luck. Scott Madison, WN1B Yahoo! Groups Links Yahoo!

Kevin K2KMB Hi Kevin, That is a very good question. I didn't try adjusting the PO as it fell right about where I wanted it. I received the service manual and schematic for it yesterday and had just a few minutes to look it over last night. It would appear that the 1-10 watt version is basically what I have made, the 45 watt PA up through the driver, which is now the final. Same transistor but a few capacitor value changes. If this is the case, Motorola rates this as a 1 to 10 watt radio. I would think you should be able to lower it to 1 watt. You may have to go back a stage to get your 500 mW. I seem to recall someone else's post that indicated thay had used the input to the PA module which gave them 700 mW. You might want to look for this post. 73, Scott Madison, WN1B Yahoo!

Title: Duplexer Question Hey all, quick question about a 2 meter repeater I just put up for testing. I'm putting out about 80 watts from the PA into the duplexer, but only getting about 55 watts out of the antenna port on the duplexer. This seems kind of high to me. The specs of the duplexer are: Power handling - 150 watts (Im running half that) Min seperation - 1.5 Mhz (I'm running 2.55Mhz offset) Isolation at min sep - 90db (the plot I was sent with the duplexer shows better than 105db on both sides because of the wider spread) TX and RX loss at my seperation - approx 1.2db I'm also having some desense when the PA gets keyed, but I'm not sure if its the duplexer or a cabling issue yet. Have to do some further research. The duplexer came tuned from the factory on my freqs, and its a six cavity, BPBR type from Fiplex so I cant see it being a duplexer issue.

FW: [Repeater-Builder] Re: Duplexer Question
Ivan, Was that attack really necessary? The machine HAS been off and I contacted you directly regarding this issue and explained that I would leave it off until another pair was found that didn't interfere with you. People like you that just jam your thoughts and comments down everyone elses throat is what gives hams a bad name. You made a request, I was unaware of the interference to you from that location, and complied by shutting down. Making this personal or using smartass email addresses like ub1lid are really uncalled for and only serve to make you look bad. Once again I apologize for the interference it caused you, but it was temporary and I shut down as soon as I was made aware of it. It would also have helped if you would have stated WHO you were in the first place, and who was making the complaints instead of just sending the email you did. If you are indeed a ham, and have a valid complaint, then why would you bother to hide it behind the email address you did, not telling me who I was interfering with, or your call sign? You could have told me all this in the first place without me having to reply to your email and solicit this information from you. And I still don't know if you have a call sign or what it is, because all you sent me in the last email was who I was interfering with. I didn't hide from you or become nasty and arrogant, and there really isnt any reason for you to.

[Repeater-Builder] Power monitor question
Hey guys, quick question for you. I'm sure someone has done this before. I had to make an emergency call to a mountaintop repeater site this evening for one of the local EMS squads because the link system stopped working. It turns out the power supply breaker popped due to a surge and they have been running on battery backup for the last 3 days and they finally died. What I'm looking for is some type of stand alone power monitor to let me know when the repeater is on battery backup. The controllers I use for my ham gear have this built in, as do most ham controllers, and will change the courtesy tone if it is on battery backup. However, this system is using a couple of Motorola mobiles and a RICK unit. What I am looking for is something I can interface into the 16 pin accy connector that will key one of the radios like once a minute and send a beep out so the listeners would be made aware the system has lost AC power for some reason. Anyone know of any devices like that? TIA to all. Kevin K2KMB Yahoo!

You might consider that type of automatic signal may not be appropriate for the service. Maybe you just need a beep after repeater activity? Maybe something with a 555 timer could be built up? Please don't use a 555 - they output square waves which sounds bad and if the TX audio filtering / deviation control isn't what it should be they will cause adjacent channel interference. A simple sine wave audio oscillator is not that difficult - a transistor, a audio transformer, and a few resistors and capacitors. In my initial response I didn't suggest keying the TX PL encoder simply because that may already be in use, and using it for a power fail alert requires hooking some kind of an alarm to a PL decoder somewhere. My offer to engineer a real solution still stands - just get me a RICK manual or a copy. Mike WA6ILQ Yahoo! Groups Links Yahoo!

RE: [SPAM] - [Repeater-Builder] re: MSR-2000 UHF PA in the Amateur Band - Email found in subject
Skipp, Thanks. I just looked here in the shop and we already have the manuals for a UHF MSR2000. ;) These were in working condition when removed from service a few weeks ago due to system upgrades and had no issues. The are complete systems, with duplexers and battery revert options already on them and were going to be tossed into the dumpster!! A fellow ham, and employee of the place, rescued them before it happened, and donated 2 of the 4 units he got to me, so you cant beat that with a stick. :) Not sure if they have a preamp or not yet, but hope to find out this weekend. I will take your suggestion and run it at a lower power. The 2 systems these will be replacing are not very heavily used so I shouldn't have any issues. I already have a pinout of where I need to grab my controller connections off the backplane for the squelch card and I'm ordering the crystals up now. Retuning and checking the duplexers should be no problem on the service monitors here. I'll check the bandpass on them but I suspect they are ok, since these were used by a FD in a large city, in a heavy rf area right across from NYC so I'm sure they would notice if they had problems with them.

Great, the manuals are really a must have. To cover the UHF MSR, you actually need all three manuals (unless you have the microfiche). The power supplies are only covered in the VHF (green) manual. I was going to run it at about 80 watts instead of the full 110. You'd do better to run 65 watts. I've not had a derated UHF ~65 watt pa fail when used with a circulator/isolator. They also have the factory duplexers with them, and I'm ASSuming they should tune down as well? Kevin K2KMB Yes, if the duplexer probe kits are the 450-470 range units. Also check the duplexer for an over re-entrant energy coupling problem. It requires a spectral display with tracking gen. I've found on a few MSR UHF 450-470 versions. This will show up as an wider (broader) than normal bandpass peak that doesn't seem to allow both pass cavities in one path to completely align as one peak. I've not yet seen this problem with the T-1500 series of motorhead duplexers. Lightning stricks might be one cause of this problem, the duplexer operation will be less than good enough. I've traced this issue to 3 different UHF duplexers sent in from various (and different) east cost locations where lightning is a regular event. I'll stay with the west coast earth quakes thank you. A previous RB post mentioned a problem with the MSR Receiver front end suffering damage from lightning strikes. The msr receiver problem might be an extention of the same duplexer damage event. It does take a spectral display/graph to really see the probe kit problem. good luck skipp www.radiowrench.com/sonic Yahoo! Groups Links Yahoo!

Daron, Yeah, I've looked at some of the repeater controllers as well, but the problem I have is that this is a crossband system, not a standard TX-RX only system.

Wondering if anyone else has done this and might have the connection and config information to connect these 2 together. The system is currently in repeater mode. The only thing Duane was aware of was that the unit might need to be configured in base station mode as opposed to repeater mode to gain access to the TX and RX audio, COR, etc, but wasnt 100% sure what needed to be done. TIA to all.Kevin K2KMBGo to www.repeater-builder.com, and then select the motorola page. There is an article on interfacing the MTR to an external controller there, and that article probably has the info you need.

[Repeater-Builder] Mastr II Base question
Title: Mastr II Base question Hey all. I have a low band Mastr II base I'm looking at converting for use as a 6 meter repeater. The comb number is S3S100TFUDA and I have the LBI for tuning it up. It looks like all connections needed to interface an external controller are available on the card cage backplane. Anyone done this before? Also, what cards can I remove from the card cage and what ones do I have to leave in? It looks like it shouldnt need much to modify for duplex operation. TIA to all for any help! Kevin K2KMB YAHOO!

RE: [Repeater-Builder] Using ICOM Commercial radios as repeaters/links etc
Jim, It's very easy as they are designed for those signals to be accessable, much like the Motorola radios. There is a cable, part OPC-617, that plugs inside the radio and brings those signals out to a female DB-9 connector. You have to cut a few traces in the radio depending on the options you need and the signals are then on the 9 pin connector, and they will still function as normal mobiles. Hope this helps.

Often it has been IC-221S or IC- 121S units and sometimes IC-111S or IC-211S units. My question is, does anyone here know how difficult it is to get the signals you might need (like PTT, audio in/out, COS, etc) from these rigs? I've searched the ICOM site pretty thoroughly, and haven't come up with much information. Regards Jim WB8AZP Yahoo! Groups Links Yahoo!
