There is probably not a major problem now but it will come.  I would still like to get a few of us together to have a face to face about what can/should be done.

I had one sugestion that we get together some Sunday afternoon.

Tom:

The discussion here was more about RFI from devices other than ham radio 
getting into TV, HIFIs, phones, etc

Although we were tweaking Gail, the problem is real, that Tucson now has 
no RFI guy at TEP and TEP appears to be ignoring the problem as they are 
not replacing Gary Bruins.

So when there is an RFI problem with TEP or other devices getting into 
the radios, is Carl going to take it under his wing and investigate it 
or what is his team input to this problem, if any.

I know there is a path through ARRL on the issue of RFI in both 
directions but I think that is after we have exhausted our efforts to 
get TEP and other RFI generators to respond.

Right now everyone seems to be happy, but, in time that is going to 
change. I know for a  fact the lines on Speedway from about Freeman East 
is pretty bad as I can hear it from over a mile away on 6 meters. I 
called that in several months ago and it didn't go anywhere. They didnt 
even call me back and as for more information or tell me to get lost.

I guess the question is what is the RFI teams charter?
