"During my morning commute, my train passes south of my club’s main repeater site. Now this is on a rather high building, in one of the highest points on western Long Island, and is pretty much line-of-site for a 4-5 mile stretch of my train ride. I tested to see if I could key up our 220 machine, and it seems that the effective range was about 4 miles this morning. Now that was just keying the repeater up. I’ll have to check to see if I can actually be HEARD on it."

One would be surprised at how little power it would take to just key up the repeater and how much more power would be needed to pass even noisy audio through the repeater. This would a great use for that second rig you have lying around, put it to work!
ReplyDeleteThis morning I tried to actually talk to someone on the same repeater. They could not hear me. This could be due to the train I was on though. For some reason the old (and they are really old) Bombardier manufactured cars seem to block RF quite well. Even with holding a radio right in the window these old trains are rough on us. Most of them have been retired, so usually we have the newer Kawasaki cars, which are not nearly as bad.
