[BC] Grounding by the sea

[William Eaton]

Please excuse my ignorance on this matter, I have to confess that my
only AM client is a rather simple daytime operation. At 1330 1 KW Day
only in sandy they get around the interstate. But not much hands on
with AM down here in flat land of sand. But someone mentioned that
there was a regulation against changing the soil conductivity ? Is
that based on conductive factor or is that done with the approval ?
My only real hard experience with AM involved some FAA stuff that was
a bit different then Broadcast. But I did spend some time at an AM
facility much lower band. The dirt was imported from some exotic
country I can't recall the name of. But the application really needed
that ground wave.

Both were Govt. facilities. Now with my one tiny church client at 1330
1KW day since they bought the little brick tx. I usually just spin the
GF every few months, check the fence dark sensor and alarms and auto
log. Being my only 501c and the Catholic network I haven't paid much
attention to the GF vs. conductive factor. In a few months they wanted
to explore getting their FM over on that site. All the tower
engineering for the move was approved. I had intended to replace the
fence and clear the brush and toss in some gravel inside. At least I
brought fiber down for the new STL feed.

I guess my questiotn is, wouldn't changing the ground conductivity be
"illegal" if you exceeded authorized GW in 73.184 and maintain 0.5
mV/m contour. perhaps in other areas water would be significant but
since our water table is at 10' at High Tide. It would take more than
water to help this little thing. In fact i was glad they asked for
higher new fence. between the new beefier tower and more skirt maybe
when I spin it up I of the wont have to start checking for missing
copper half the time.

Besides everyone knows that in Fl. AM is great for road work and
disney parking.

But is that why changing the conductive factor would be a no no ?
How on earth could you measure that ratio off paper ?
