All very good points. One thing a lot of hams forget is that it MUST ID. It is a repeater. I have a TM-742 in my SUV and it gets used to extend the range of my HT.(cross band) It ID's I hooked up a Comm Spec cw ider. Would I use this as a full repeater? NO WAY! Get an old Master 2 or something and make a nice real repeater. Good luck! 73 Russ, W3CH Trustee W3PS Metro-Comm, INC Repeater network.

I am thinking of Yaesu FT8800R. How high should the tower be? I want the coverage at least 20-30 miles. The area here is perfectly flat with most building as high as 24 feet. (densely populated area mostly houses) Any advice? > > > > > > Yahoo!
