(since June 17, 1972)
FIRST and LAST are the respective logging dates (in mm-dd-yy format) of the
station by tropo. (Stations under 250 miles are NOT relogged.)
Loggings via other propagation modes may predate and/or be subsequent to them.
Station relogging counts are often only shown for those over 300 miles.
Long-vacated channels later reoccupied are counted as new - like Laredo's
92.7 MHz. A "+" indicates that the station has QSYed, "=" means a
cessation, "d" is for station drift caused by their technical malfunction
(that, so far, having only been noticed with two semi-locals), and "s"
is for a definite transmitter spur. Any area pirate stations are
NOT logged!
Whenever possible, the CALL letters are those in use at the time of the
FIRST tropo 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 in the 12-02-57 to 08-07-66 era was about 1.5 miles se of the
current QTH. The 10-31-69 to 06-17-72 one was about 6 mi sw of here.
Any milage variations resulting from those moves are not taken into
account here.
Equipment from Aug 1962 to Nov 1970 was a 1949-vintage Stewart-Warner
AM/FM/PHONO with indoor wire. Nov 1970-Aug 1973 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.
