SAN ANTONIO, TX 29° 28' 08" N 98° 35' 32" W
(since June 17, 1972)
FIRST and LAST are the respective logging dates (in mm-dd-yy format) of the
station by Es.
Whenever possible, the CALL letters are those in use at the time of the
FIRST Es logging. Any call in parentheses was the one being
used when it was LAST logged. Some of these stations have gone thru
a half-dozen (or more!) call letter changes over just a few years so any
call that they are now currently using could be even yet different.
Where transmitter coordinates are known, the distances have been calculated.
Otherwise, the Feb 1968 National Geographics US Map (72 mi/in)
was used for measuring to the center of the city of licensee, with that then
being rounded off to the nearest 5 miles (which in the case of "rim shotters"
could produce a considerable error).
My location prior to 06-17-72 era was about 6 miles sw of the
current QTH, and any milage variations resulting from that move are not taken
into account here. Only around a dozen Es stations were
uniquely logged from that prior address.
Equipment used Nov 1970-Aug 1973 was mostly a Wards AM/FM/POLICE
portable with indoor wire, with some use of an Allied 426 tuner from July of
1972 with an Archer V-100 at 20' with rotor. After that an SX-62 with some
simple International Crystal preamps, using a 6-el Archer FM yagi at 20'
from Apr 1977. Since October 1979 the current Realistic
TM-1001 tuner has been used with two of its four
10.7-MHz ceramic i.f. filters being replaced with 150-kHz bandpass units in
June 1990.
