[Repeater-Builder] linking frequencies?
Is 900 Mhz still useable for repeater linking, or is it so full of garbage that there would be problems? How about 440 Mhz? Thanks, Al KB2AYU
[Repeater-Builder] Micor has me stumped
I have both a vhf and uhf Micor repeater that I'm interfacing. I now know a whole lot more about Micor repeaters than I really wanted to. The short version of the problem is as follows: The COS signal from the audio/squelch board goes away when the TX is enabled. If you transmit a continuous carrier on the input, The COS comes up for a split second, keys the TX then goes away. After the hangtime expires and the TX drops, the whole things starts again. I have the exciter and RX into 50 ohm loads. If i put the A/S board and squelch gate into the uhf unit, it works fine. I have checked and double checked everything. It just doesnt make any sense. Any ideas would be greatly appreciated. Al KB2AYU Yahoo!

[Repeater-Builder] 2 meter receiver with afc for use on 1.2Ghz
Hello fellow repeater builders. I am new to this excellent group. I have been running a repeater on 1.2Ghz using a Hamtronics 2 meter repeater along with SSB electronics RX and TX converters. It seems to work very well. The Hamtronics receiver has very "tight" selectivity and I was wondering if there is a different receiver I could use that has AFC to take into account off frequency TX's at 1.2Ghz? Also, would there be a downside to using AFC? I would like to make this repeater work as good as possible. Thanks for any comments. Al Yahoo!
