I have a couple of 900 MHz Micor receiver boards lying around and am thinking of putting together an amateur repeater (else selling them). I live in an urban environment. However, with all the unlicensed frequency hoping devices around, is it worth the effort to put up a 900 MHz voice repeater? A friend bought one of these 900 MHz baby room monitors.... every few seconds a burst of noise is heard as the town's traffic lights are controlled by 902-928 MHz RF frequency hoping links.

Any views on this?

A lot of that garbage stuff - cordless phones & such - is going to 2.4 GHz. Recent 900 stuff is often spread spectrum, so maybe the worst of the interference on the band is past. Also, a lot of the license free stuff stays in the middle of the band whereas the SCRRBA band plan puts ham repeaters at the ends, inputs 902-903 and outputs 927-928.

Activity seems to be picking up around the country. Check out the AR902MHz group at groups.yahoo.com

All of my repeaters are open. I am going to try a different repeater on Porter Mtn before I change frequencies. The new one will go up tomorrow, unless it snows ALOT. Same freq and tone.
