In December 2004 / January 2005 I scheduled several beacon tests on 30 meters with David, VK6DI, in West Australia near Perth (OF88cc). The distance between our stations is 13584 km. David asked me to run at least 1 watt power making it easier to find my signal but the avaible beacon transmitter yields not more than 250 mW. After adjusting the lower power limit of my old ICOM 725 transceiver to 1,2 watts by the internal potentiometers I started a first QRSS3 test on 5th Dec. 2004. In the beginnng David could not find my signal due to a difference of almost 50 Hz between the actual frequency and that what the display showed. Also the cw keying was not free of FM and the relatively "high" power caused splatters on the monitors of european listeners. Therefore, I decided to use the ICOM never again for QRPP beaconing. The antenna was a simple 30 meters half wave dipole approx. 8 meters high in SW/NE orientation shown in the picture below during sunset at 16:30 local time (4th Jan. 2004).

1.2 watt signal from ICOM 725 with bad modulation


And this is what it looked like at the other end in VK6



*** 11/12th December 2004  -  50mW ***

I reinstalled my 200 mW homemade beacon tx but for a unknown reason no more than 50 mW power came out. Sick and tired of searching for the defect I started the test with lower power. The original signals (green) and some captures from VK6DI, G0DJA and G6AVK below.


True, a highly individual signal shape :-)

G6AVK.


Playing again with the software features of the CWK2 control unit a new wave form came into being.

G0DJA called it "the children's sand castles"



*** 31st December 2004  -  240mW ***

After repairing the beacon TX, 240 mW are now available again. The message consists of 2 x 10 trapezoids, a DFCW, a QRSS5 and a "Slow Hellschreiber" portion. Only faint traces from the Hell in VK6 whilst the trapezoidal wave was copied well.

In the first January week several experiments with outputs from 40 down to 2.5 mW followed. A summary of the results is shown in the pictures below.

*** 1st January 2005  -  40mW ***


Less power but a quite good result !



*** From 2nd to 6th January 2005  -  20mW ***


Weak traces of the trapezoid were detected on 4th Jan. at 15:17 utc


Rising propagation conditions on 6th Jan. at 1834 utc allow clearer signal copies. The QRSS transmission
of OM1II appeared suddenly in a clandestine manner below mine :-)



*** 6th January 2005  -  10 mW ***

On 6th Jan. at 19:30 utc I was asked by David for dropping down power further to 10 mW. As he browse through his captured files on next day he was taken by surprise. At 21:18 utc the signal came up again and was much stronger than those previously seen at much higher power.


The 10 mW signal during a second band opening between 21 and 22 utc on Jan. 6th, the best result so far.



*** 11th January 2005  -  5 mW ***


Weak but 100% ID in VK6 at only 5 mW !


During the VK6 experiments, a lot of reports came in from Europe. Thanks to all who followed the transmissions, but I am sorry to say, I cannot pushlish the whole stuff here on this page.
