Hi VLF friends,
For those how could be interested in local VLF experiments, i'm now
transmitting on the 70m long 30m high antenna with the LOPT
transformer. TX power is just 3W. Mode is QRSS-400. The transmit
frequency is 5.756666 kHz, GPS "locked" in SpecLab.
Last night i've done a first local test on that frequency, 30m
distance. The signal was visible in the grabber window, as well as a
weak 3rd harmonic was detected (3HD) at 17.27 kHz.
Now, with the todays experiment i'm trying to receive that weak signal
on 5.75666 kHz from my home QTH in nearly 1 km distance. If successful,
a few /p receive tests will be done. And, in previous tests, "the big
coil" will be used.
73 and gl with your own projects :-)
