[Repeater-Builder] Re: Antenna suggestion question?

If you do go with a side mount fiberglass antenna, be sure to get an outrigger arm for the top. It will prevent the top from blowing in the breeze. I have seen more problems in fiberglass antennas where they were only clamped at the base. The internal connections which are soldered don't hol

Around 700-750 Hz is a comfortable setting, (I'm not sure what frequency will make you deaf...) If deafness is really a consideration, turn down the deviation on the ID to 50% of your voice level and everyone should survive. As for speed...can your users copy CW? If not...the maximum speed allowe

Re: [Repeater-Builder] Help with intermod between repeaters.

We have a similar problem in the Twin Cities in Minnesota where we have two AM broadcasting stations that are 600 Khz apart. One is a 50,000 watt station on 1500 Khz and the other is a 10,000 watt station on 900 Khz.  They are located about 5 miles apart. qs both stations are on-the-air

Re: [Repeater-Builder] Help with intermod between repeaters.

I hate to tell you, a definite way to eliminate the problem, is a frequency change so that the output of the two transmitters are no longer not 600 khz apart. It is possible that the mixing is occurring in one of the PA's. If the problem is a mix in the TX, an isolator on the offending TX shoul

I ran a 6m and 70cm multicast repeater for years with 100' horizontal separation and 30' vertical separation. Granted the vertical separation makes more difference but the 100' horizontal certainly didn't hurt. I ran 100 watts on 6m 1.7meg split and about 55 watts on 70cm. I did finally get 2 smal

RE: [Repeater-Builder] Help with intermod between repeaters.

The first question that enters my mind is, were both Micor stations originally built as repeaters, with the extra filters and shielding plates, or are one or both base stations that have been converted to repeaters? It is important that the extra shield plates provided with repeater stations are s

Re: [Repeater-Builder] Help with intermod between repeaters.

You need to reject the opposite TX on each repeater. Your BP filters were set wrong. You rejected the RX on the TX side - something the duplexer should be doing already. You need to install them in the repeater and reject the other TX. IOW, install a filter in the .16 repeater and notch the .36

Bare with me this is a bit long. Our repeater is on 146.76TX / 146.16RX. In the next town the repeater having the problem is on 147.36TX / 147.96RX. Both repeaters are Motorola Micors. Our repeater is a 100 watt PA running about 60watts with a single band pass cavity between TX and a 4 cavity BP
