[Repeater-Builder] Re: Micor Base Station Amp Problem-CURED

Hi all, I just found the problem with this transmitter, problem described below. To force F1 at all times on the exciter, I jumped from the channel element pin to Switched A-. NOT a good idea. Doing that apparently creates a ground loop and an oscillation at around 50kc. It did this with two di

[Repeater-Builder] Celwave Preselector Tuning

I have one of the small 941-PB4-2-3 Celwave Band Pass Preselectors ( UHF ). There are 7 stubs, 4 are on the pass cans, 3 in-between the 4 resonators. Adjusting any of the 3 stubs (between each of the 4 resonators) has little effect on the skirt. I might assume that these 3 might be related to ban

Re: [Repeater-Builder]Transmitting interior temperature

I have a 440 repeater at a high mountain location. I would like to know the interior temperature of the repeater building. The building is heated. Does anyone know how I can connect a voice sytem to the 440 repeater to transmit the temperature, when the repeater ID's? Any ideas will be greatly ap

The Coordination of a repeater is not a technical aspect of its building. I don't know when you subscribed, but this list has never allowed lengthy discussion of non technical aspects of repeater building, especially coordination. There is no technical good going to become of a coordination d

Thanks guy for all of the answers. This has really given me something to think about. Let me start by acknowledging all the obvious typos that have already been fixed (darn and I proofed that twice). Yes, the tower spacing is vertical (not horizontal), yes the tx/rx on the repeater is 443.3 and

Re: [Repeater-Builder] Adding Remote Base to a Repeater

Dwayne, 2 possible answers: 1) Eliminate the current T/R switching so that you can bring out a seperate TX and RX path, then add the filtering as needed and then go to a new T/R relay. OR get behind the current T/R switching and take the individual paths thru the necessary filtering before co

Mr. Schmidt, Isn't it strange how irrate these people get when attention is being brought to their short commings?? I too have had this same experience with the cooridinating association in my area and the response to my complaints was identical to the response to yours, seems kind of strange it w

Re: [Repeater-Builder] Re: COS output for Kenwood

Hook that signal to the base of the transistor through a 10K or so resistor. That should provide enough isolation to prevent loading of the signal. I hope it's going positive when the squelch is open so your COS will be low when active. de WD7F John in Tucson - Original Message - From:

[Repeater-Builder] Motorola Spectra as a remote/link radio

Hi, Does anyone have any experience good or bad with a Motorola Spectra as a remote base/link radio? How does it compare to a Maxtrac in this capacity. Thanks, Sean

[Repeater-Builder] Re: COS output for Kenwood

Jim, thanks for the suggestion. Unfortunately it doesn't have a receive LED, only a bar-graph which is also used for transmitting. The optoisolator idea has merit though. I have located a point in the radio which changes voltage, but only by about 1/2 V and it is very sensitive to loading.

In my state, the coordination council updates their web page maybe the day after a meeting, telling you about the meeting you missed the previous day. Minutes of meetings are posted similarly way out of date, if at all. Their on-line repeater list hasn't been updated in a year, and it's not as if t

Re: [Repeater-Builder] Need Mastr ExecII mods.

You will probably need to change components to get it to tune up. Any coil that won't peak needs a cap change. And when I say peak, while tuning it must come up to the peak and then be able to tune past the peak (come back down on the other side). Chuck WB2EDV - Original Message -
