Part 15 Close To the Vest
Perhaps because I perceive my neighborhood as a cross between gentry and Christian I am very timid about being too "loud" about broadcasting from the house. After all I have atheist programs and what could be more hated by dull people who are hard up for something to attack.
The AMT3000 with home-made loading coil is ideal for the shy approach, it resonates the building's ground system putting excellent coverage throughout the habitat while reaching only a dainty 250-feet outward.
But there are night's like these when testosterone kicks in and I fire up the AMT5000 with its ground radials and get out 1,000 feet! The boldness of it!

i'd throw that bad boy up outdoors over a ground plane and hook up the carrier current and say to H*ll with them :-)

Well yeah, the thing is I don't think people are all that observant of things, connecting antennas to a specific broadcast they're hearing on a radio. By the time they tune it in, likely your antenna will have been up for a while and they won't connect it. I also think that average listeners tend to blame the host of the show when they hear something they don't like, not the station, at least these days, when stations aren't so together and friendly, and most run national feeds.
Other radio sites I've seen monger on about sounding like other stations to blend in, and never allow programming with curse words, but even that doesn't bother the majority of people these days, and fewer notice sound quality unless it's practically unlistenable.
We are advanced listeners, where most don't know about any particular station or how it got there technically, it's just there. It's not that listeners are dumb, they listen for different reasons, maybe smarter ones, a direct line to the program rather than judging the merit of the station's broadcast quality or the quality of the sound on the receiver they're listening to.
For me, I put a lot of time into my station, and some money, and want to get out there best I can under P-15.
Otherwise, if you're really interested in stealth, Carrier-Current would be a great way to broadcast, no visible antennas! You said you had inconsistent results though Carl, where in dry spells, the range is small, but when it rains, the signal gets out like a tsunami, were your words I think.
I ran it by a radio friend of mine who is the biggest carrier current spokesperson I know, and showed him your post. His idea? You need a better ground, and in my experience too, there shouldn't be that much difference between wet and dry ground. There are some variations, mainly in fringe areas anyway, but they shouldn't be large.
You could even do other things, like disguise your antenna as a flag pole, or have radials on it like a CB antenna would have.

I've experienced the very same range issues you're experiencing on FM as well. When it is what my range is greater and the pattern does seem to change. However when it is dry the range is less but the pattern again changes.
I have always thought that FM the pattern would stay the same and as there is a temperature inversion or more moisture the only thing that would happen is that the range would increase but keep the same pattern. However that is far from the case.

I used to ride with a portable FM in my bus to and from school, and noticed that FM signals seemed to weaker or more unstable when it rained. The signals shouldn't be that much weaker, but could it be reflections from the wet ground caused more multipath? Maybe it was just in my imagination.
