Hey Barry, are you saying we are lids down here? I resemble that remark.

If we can get the emotions and people out of this and use technology and 
logic, we can sort through potential improvements. I think the goal should 
be to be sure our systems work as well as possible.

1.) Receiving.

Compare what we hear to what others in our general area can hear. 
Signal-to-noise at HF almost exclusively relates to local noise floor and 
how directive our antenna patterns are at useful angles....not antenna gain.

The exception to this is if we have feed system problems that allow common 
mode noise ingress.

There is a HUGE difference in my noise floor out on a dirt road with hardly 
any power lines or neighbors for miles and what I could hear at other 
locations I've lived at.

2.) Antennas.

Anyone wondering how their antennas work now only needs to look at skimmer 
reports compared to other local stations. This is a great tool for 
transmitting gain and how often signals fade (which has only a little to do 
with receiving ability).

One local station has a tribander that amounts to four-element antennas on 
20 and 15 meters, and the equivalent of maybe 5-6 actual contributing 
elements on ten meters on a 34 foot boom.  It is interesting to look at his 
signal compared to much larger arrays on skimmer records. Skimmer is a great 
tool for looking back at signal levels over time to see where we need 

After working 160 and 40 in contests, I'm convinced a well-planned carefully 
installed station in a good location in the SE could do just as well or 
better than any winning station in the NE, provided operators were the same 

The only people with the real location problems that may be insurmountable 
are those up in the north and west. They have a path problem limiting 
propagation, and that might be insurmountable. Oddly, they don't complain 
much.   :-)
