Re: [Repeater-Builder] Repeater Kerchunk
I agree with all the comments. What I do is listen to the signal, usually there is a distinctive sound from the mike being squeezed or noise on the signal, I'm almost certain who my kerchunker is, as he has used my repeater before!

I've had several repeaters for years and have learned that the kerchunkers are usually someone who has just discovered your repeater and want to know how it covers an area. They'll drive around testing it in many areas. It usually goes away after a few days when they finish their testing. Other people just kerchunck the repeater to see if it's on the air, or that their radio is still working. As a repeater owner, you have to deal with many types of people and personalities. If you show that you are getting annoyed, the kerchunking can get worse. Many repeaters in my area have had problems with users, I haven't. The problem people usually go to a repeater where they get attention. I ignore them. 73, Joe, K1ike --- Ken

Thanks for the info, that is encouragement. On Sat, Jan 17, 2009 at 10:19 AM, Jim Brown w5...@yahoo.com wrote: I have recently moved a GE Mastr Exec II radio from the 47 mHz area up into six meters. (The MVP and the Exec use the same exciter). I'll admit that the exciter is hard to tune, but it will work without any modification. My technique is to set the frequency of a receiver to each multiplier frequency and place a probe near the stage while tuning. With a peak in signal strength, the stage can then be tuned with a meter on the test point. I built a probe that I use with a one inch piece of insulated wire extending from the end that I can insert into the exciter near the stage I am trying to tune. This same probe works to insert a signal generator output into the individual stages of the front end of the receiver. Tune the mixer first and then work toward the input one stage at a time. 73 - Jim W5ZIT --- On Fri, 1/16/09, Radio Guy ve3...@gmail.com wrote: Speaking of trying to get a radio converted to 6m, a GE guy is having problems with a GE MVP, has anyone been successful getting a radio to cover 52.450 and 53.450?

[Repeater-Builder] Lunch Box Radio
Any one familiar with the GE Porta Mobile two? It is a low band radio, and I would like to have it converted to the 6m band. I send it to a local shop that was familiar with GE products back in the day, they say it is in very good shape. Any ideas on a company that could make the crystals? Is this a worth while project? Showing hams this radio always brings a smile to their faces,a portable radio that is bigger then most HF mobiles! The tech said... if we need to change out caps, it would be a job for younger eyes! -- --- Ken
Re: [Repeater-Builder] Lunch Box Radio
The Ge shop told me that he has some test connectors, for alignment purposes, and I would have to use a different type of battery. Since the battery case was modified, I may be able to fit a sealed lead acid in the overblown case. Interestingly, the Motorola tech just dropped by looking for connectors, and I mentioned the crystals to him, he makes regular orders of crystals and is interested in obtaining the rocks for me. So far all is going well. Any yes, it is a historic piece of equipment, people whom recognise the low band radios have stories to tell about firefighters preferring the long range of heavy radios.

Re: [Repeater-Builder] Lunch Box Radio
Yes, that is something that has been mentioned many times, this could be a waste of time and money, but so far I have lots of people that want to help. It could be a fun project, it is old enough to look like a tube radio, or in this case, a tube radio without tubes!

Re: [Repeater-Builder] Lunch Box Radio
That is the big problem, people had the manual, somewhere, even the shops had all the manuals.. Think we threw that out years ago, with all that tube stuff... When we were looking, found a Phoenix manual, but no MVP. I will look around the Internet tonight after work.

Re: [Repeater-Builder] DTV ch 2 vs 6m
That's a good question, after all of us got use to the channel 2 problems from analogue. Locally our channel two is staying on the air with analogue as we in Canada are not changing for some time. It is possible I will be receiving new digital signals as well as analogue interference when the band opens.

Re: [Repeater-Builder] Motorola CDM-1250 PL tone control
If you find out how to do that, let me know! I gave up and switched to Tait TM8110 it allows ctcss injection. We are using a pair of Motorola CDM-1250 UHF mobiles, 403-470 split, for our UHF repeater along with an Arcom RC-210 controller. We want to strip the PL tone when CW and / or Voice ID's are sent. The arcom controller has the capability of sending logic out to the radio or an external tone board to turn the encode on or off. Does anyone have any knowledge of how one might be able to inject the CTCSS logic into the 16-pin accessory port, or otherwise connect to the CDM radio and control whether the CDM will encode our PL tone or not? Another option is the CommSpec SS-64, which I have on hand. However, we cannot simply parallel the tone output into the pre-emphasized audio input of the radio. I know that the radio could probably be programmed for no pre-emphasis, but I don't want to bypass limiting. Ideas or suggestions? Maybe someone knows a good location to inject the tone directly into the radio's modulator?

Re: [Repeater-Builder] Motorola radios on ham
The CDM series are good radios and they have large heat sinks for us talkative hams. Speaking of Motorola radios, has anyone been able to convert a new series radio to six metres? Still a few companies left making low band radios but the frequency stops at 50 Mhz and according to the service shop they cannot stretch like the old radios did.

Re: [Repeater-Builder] HELP NEEDED - Programming Motorola GR-1225 repeater accessory port
I had similair problems when I tried to interface mine to a NHRC controller. My solution was to call the local Motorola dealer where I bought it from and tell him the two controlers would not play together. ( The repeater has a built in controller ). His solution was to shut off the repeat function, using software. Problem solved. Sorry, I can't help more, and I don't know what commands he used. Now I have a separate transmitter and receiver, at least as far as the controller is concerned.

Mind you I am 1000 miles away, and can only help over the phone. The problem occurs when he tries to operate full duplex. The repeater works fine on its own, and works fine when the node is operating in half duplex. But as soon as the External PTT is asserted on Pin 3 of the accessory jack, the RX Audio from Pin 11 is being muted. I have been looking through the help file for the WinRSS that runs the 1225 series, but for the life of me I can not figure out why a full duplex repeater would do this. The audio from pin 11 needs to be squelch muted, but why is it also being muted when the external PTT is applied? Can anyone come up with a solution? How would you ever be able to configure this repeater to use an external controller? Dave Cameron - VE7LTD IRLP System Designer --- Ken
