I have been using 1700 for my tests, b/c it’s a nice, even, easy-to-remember spot that sounds good with produced imaging. Would like to stick with an even freq of that respect, but of course, it won’t do me any good if I can’t get any decent range.
It could very well be interference. There isn’t much on 1700 to be picked up during the day, but at night it can get noisy. The tests I’ve done were both at night, way after sundown, and during the day… same results at either time as I described using the ATU. The wire antenna’s signal was fairly clear, but only covered the area surrounding my building (as the system was designed for). The ground used with the ATU was a metal roof in all instances, giving strong readings on the tuning meter.
The closest adjacent active stations are 1640 at 5 miles, 1580 at 15 miles, and 1490 at about 13 miles. I used Radio-Locator to find everything within 200 miles, and I have a 1000 at almost 200 miles away, but 990 and 1010 at less than 100 miles away.
Too close? Even for daytime? And should the heritage “clear channel” freqs of the big stations be avoided, or does it really matter?
