(note: because of the specs in excess of normal part 15 levels, I'm posting the question here...)
I was curious about what the approximate coverage area of a station might be with the following (not that one exists or would, I just would like to have some idea):
50kW omni-directional (a DA would complicate calculations, but let me know if it's possible to reasonably calculate it)
center-fed full-wave (two 1/2-wave antennas stacked) antenna over a complete ground system consisting of 120 evenly-spaced 1/2-wave radials
AM 530 (yea, no licensed stations yet, but TIS's are there - just wonder how well 50kW would do there)
soil conductivity 30 (or whatever is the highest encountered on land; assume that soil conductivity is on the entire planet with flat ground)
(basically, I'm looking for best-case scenario that doesn't involve a salt water path)
maybe R Fry might be able to calculate the answer to this. (he seems to be able to - I haven't figured it out yet.)
Also, besides the normal coverage distances R Fry has calculated for part 15 systems in the past, I would also like fringe coverage on a walkman (to where the signal is barely readable enough to make out intelligible speech, on a good-quality Walkman (SRF-42 for example), fringe to walkman with properly-tuned Select-A-Tenna, and fringe to walkman using Bruce Carter's (or someone else's if there's one that's better) best large AM tuned loop antenna.
Also, at lower power levels, what about 500 milliwatts and a 15-meter antenna (100mw*5 and 3m*5), or 1 watt and a 15-meter antenna (160-190kHz levels), at 1610kHz, over a decent (for a part 15) ground system, ground mounted?
