Hello Jeff,
All those things you mention are great but times they are changing. You
would be well advised if you find an interesting place to do a noise survey on
and near the property. And consider what are the chances of urban sprawl to
bring with it the latest scourge of a plethora of noise emitting switching
devices. I am fighting one as we speak from a lumber mill making dimensional
products that has moved in just across the street from me. Their fancy energy
saving VFD drives has raised my noise floor over 20 dB on some areas of my
property.
So consider this to be one of the biggest items on the checklist for a new
site.
Good Luck,
Lee K7TJR OR

Subject: Topband: Soil conductivity maps
So I'm looking to purchase a new QTH. I'm not particular about location, but
would like to optimize for soil conductivity and any other parameters that
would increase near and far field propagation and minimize ground losses. I've
seen the US Gov M3 maps, but they are very coarse. They also only define
conductivity, and I'm wondering what other quantities would be useful to look
at.
I know that a salt water takeoff or marsh is awesome, but that's not gonna
happen in this iteration - looking very much central USA (W5, TX), inland.
So, any more fine-grained maps available? Or other quantities that would be
worth looking at? Books that discuss this sort of thing?
Mostly for either pinpointing optimal areas, or making sure that a good looking
property is at least half-way decent...
Thanks for any guidance,
de N6GQ
