Ed RU6LA,
My home station receiving setup is an active antenna feeding a TS-850 and
Argo looking at the audio. The active antenna is a 10 metre insulated pipe
guyed in a tree in the rear corner of my property, there is a high impedance
low pass filter before the first active device, gives essentially broadband
performance within VLF and LF, plenty of gain and balanced shielded feeder
(computer data cable, buried) to the shack. The TS-850 is in CW mode set
for 270 Hz bandwidth, NB1 on, fast AGC and 800 Hz as centre frequency. For
unattended operation I run all gear through a constant voltage transformer.
I do not use the 1 Hz tuning step capability as the '850 digital dial only
displays to 10 Hz, and it can be tricky tuning between and being certain
which 1 Hz step applies, so by having the '850 at 10 Hz steps only I do all
fine tuning using Argo. So for RN6BN with a declared frequency of 137.703
kHz, I set the '850 dial at 137.70 kHz and set Argo for 803 Hz at centre of
the waterfall display.

It is very good Easter news for LF-enthusiasts and especially for
Europeans ! - first Eu signal received in ZL - CONGRATS Bob ZL2CA and
Sam RN6BN!
This is distance abt 16438km (RE78IR - KN95LC) in LA0FX's soft - new
world's 1-way QSO record on 136kHz band!
But calculation of distances between two points a very hard task for the
very
large distances.. The majority of the programs consider the Earth as
absolutely round...but no fearl!...
All distances in the my table "Best QSOs"
(http://136.73.ru/h_qso/index.htm )
are calculated by the program LA0FX and in basic on QTH-loc (distance
centre to
centre of QTH-locs -> mistake up to abt 10km).
PSE inform me abt programs takes into account unspheric of the Earth - I'm
recalculated mine tables (some in geographic coordinates).
I nor am sure in completeness of my tables - PSE correct my info!
Bob ZL2CA and Sam RN6BN, PSE inform us abt yours RX - TX setups under
this beautiful receptions.
