VLF report from pa3guc (Jaap) qth Leens JO33EI
==============================================
Date: saturday oct. 17th, period 07.00 - 08.00 utc
PA0SE 136.56 kc/s rst 559
G3LDO 137.57 529
G3XTZ 137.11 539
Rx is a Kenwood TS570D, IF cw-filter 270 Hz.
Ant. G5RV (legs 2x15.5 m, height abt 9m) and 12 m
open feeder with short circ. and tuned to 50ohm
by means of a coil.
Also experimenting with a Frame Loop (70 cm square)
and 42 windings. The coupling coil is also 70cm square
with 5 windings and connected to a symmetric Fet based
amplifier (Datong AD270)
Last saturday (oct. 10) i took part in an experiment with
Pe1pfr (designer and builder 136 kHz Tx), Pa2njn (Opr)
and myself for the receiption.
We used a Kite (4 by 2 m) to bring out 180 meters antenna
and the Tx produced at first abt 80 watts, ltr on when the swr
improved, we could produce 150 watts. (abt 1.5 watts radiated)
We also tried to receive with the above mentioned antenna's, but
i still experience best rx-results with my own G5RV with
open feeder.
Saturday Nov 14th, we plan to QSO again on 136, with an
improved Kite/antenna (A Kodi), length and height more than 300
meters (as we hope, hi).
I would like to get some info.... What's in your opinion
the best receiving antenna?
Best 73's from the 136kHZ crew Wim/pe1pfr, Nico/pa2njn and
Jaap/pa3guc,
hpe meeting you on vlf !
