QSL !
Well if its stamped 'issued' then who's going to complain. that
covers audio / 136 lofer 500 and MW , with 1/2 KW erp ..
game -on !
Nice touch on the defining the state of Florida, so say Andy KU4XR
is out of the game . where as EU or say South America is 'in' ..
nothing to do with N/S divide ? , as opposed to the mid latitude
trough , that was elegantly portrayed at the rsgb convention ..
showing a dead zone directly from the UK to Newfoundland .. some
things are best 'un-known' ... especially when your trying for a
500 UK/VE cw contact on the night of the April IMD event ,,,,
Good luck with the 500 set up , don't think you find too much
problem radiating on 500 , as long as you have round 30 ft of
vertical wire from the feed point , that's seems to be enough , Top
loading also seems to be a good move ..sea water close by also
helps .. ok 750 ft over sea water (ever glades ?) or 600 ft in a
delta loop helps , but with a little 'data processing' then quite
good coms over range is possible ...... I must admit I floated down
from 160 to 500 and found the 160 short array worked fine .. big
power gain was the earthling ... anything in the garden that
conducted, now has its own insulated earth cable .. and the top
loading coil wound on 2 coke bottles , coaxially assembled , gave the
second ... third was the 'Doppelgänger' PA .. but that's another story
...

Graham,
From Juan's application:
"This Experimental License is required in order to sanction our
experiments of
attempting communications between Licensed Radio Amateurs in Miami,
Florida and
those licensed in other parts of the world at approximately 136Kc and
500Kc.
These communications are being attempted in CW, LSB, RTTY, and any of the
digital modes such as BPSK.
For this purpose we will acquire from commercial firms, radio
amateurs, or design
and build the necessary transmitting and receiving equipment, including RF
amplifiers not to exceed 500 Watts in output."
However it appears that the application was not too carefully
scrutinized, for example he mentions that he will run 500W output yet
also specifies an ERP of 500W.
Also he requests 130-140 and 495-505kHz with a frequency tolerance of 95%!

10.15.2011 - FCC issues Experimental License Grant WF2XXQ to operate on
the
130KC and 500KC bands to Licensed Radio Amateur Juan A. Granados /K4LCD
until 10.01.2016.
As part of our VLF - Very Low Frequency amateur radio experiment, on
September 6, 2011 we submitted an application for an Experimental License
to
operate within certain parameters in the 130KHz and 500KHz bands.
We have been listening successfully to experimental transmissions of some
of
the 45 licensed amateurs participating in the experiments conducted under
an
Experimental License granted to the ARRL in the 500KHz band.
Receiving with a RFSpace SDR-IQ SDR Receiver w/HB9HRV's SDR-Console
software
and a Kenwood TS-2000, NE and NW loops of the 4 x elevated EWEs designed
by
Floyd Koontz WA2WVL.
With the help of Floyd Koontz WA2WVL, we are involved in designing
complements to our existing 160M transmit antenna so that it will
transmit
at 500KHz. We now have a preliminary design.
Floyd Koontz WA2WVL is very advanced in the development of a 28.5MHz
transmitter down converter and solid state RF amplifier to provide us
with
approximately 300 watts output to operate at 500KHz.
