RE: [Repeater-Builder] Repeater /Crossband Help
Don, There is an article on the Repeater-Builder web site (not the Yahoogroup page) about how to disable the "always on" channel element in the Micor exciter. I think this is what you need to eliminate your problem. It is described in this article: http://www.repeater-builder.com/micor/stationcontrol.html Look in the section titled, "Keyed Exciter Channel Element Modification" Also look here: http://www.repeater-builder.com/micor/stationmod.html about half way down the article, under the heading "Modifications relating to the chassis" and find the subsection titled "For the Transmit Exciter you have a choice:" I also thought there was a more comprehensive article describing the issue you are experiencing, but for the life of me, I cannot find it right now... Mark - N9WYS -Original Message- From: Repeater-Builder@yahoogroups.com On Behalf Of ka9qjg1 Hello hope Everyone is doing well, I have ran into a little Problem and thought I would get some suggestions on how to resolve it I have a Motorola Micor 224.40 repeater built By Scott N3XCC , here on the Repeater builder group; it has worked great for over 3 Yrs. I have a Few Hams in the area who do not have 220 but the know and would like to talk to some of their friends who do , So I took My Kenwood TM-631 Duel band found a Local 2 Meter Simplex that Myself and a few others have been using for over 20 Yrs . I turned the 220 Transmit down as low as I could get it which is 2 Watts That goes into a Bird 100Watt Dummy load . The 2 Meter side I have set a 10 watts and a 3 In muffing Fan that runs while Transmitting It runs nice and Cool , Everyone likes it and it works fine Except that is has been keying up on the 2 Meter side off and on sometimes as long as 3 4 Min Unfortunately I had disabled the TOT And on this Radio you can only have a PL On one side and I need that on the 220 side . What I think is going on is that the Micor 220 has a Very small signal on the output always being transmitted. No big deal except for what I "am trying to do and that will random bring up the 2 Meter Transmit. This radio has the 6 In Pigtails coming out to a SO-239 I wrapped them with Foil and Moved the Duel band radio about 10 ft away from the Repeater which is in a 4 ft Motorola case . The link is being Id When the Repeater is being used. Any thoughts will be great appreciated, The hams using this really like it that don't have 220 they can now use their 2 Meter Mobile and Ht . Thanks Don KA9QJG

Sounds like your channel element is "running all the time" You may need to force jumper your ptt to ground all the time and reconect your controllers ptt to the channel element select line so it only runs when it needs to. Other than that about the only thing you could do is place an attenuator in line with your remote base receiver. I am sure Scott can tell you how to do it the right way. tom ka9qjg1 wrote: > Hello hope Everyone is doing well, I have ran into a little Problem and > thought I would get some suggestions on how to resolve it > I have a Motorola Micor 224.40 repeater built By Scott N3XCC , here on the > Repeater builder group; it has worked great for over 3 Yrs. > > I have a Few Hams in the area who do not have 220 but the know and would > like to talk to some of their friends who do , So I took My Kenwood TM-631 > Duel band found a Local 2 Meter Simplex that Myself and a few others have > been using for over 20 Yrs . > I turned the 220 Transmit down as low as I could get it which is 2 Watts > That goes into a Bird 100Watt Dummy load .
