On tämä kaiketi ainakin ruotsalaisille vastaillut joulun jälkeenkin; liekö
Suomi boikotissa.

Ämne: New Years Day DX Challenge !!
Hello Thomas !
Here is an upcoming DX target on 468 khz. Brett Saylor in Pennsylvania heard
the broadcast over Xmas, did the research and we contacted the operator asking
him for another broadcast. He's agreed to do one over new years. Details,
below.
It not SAQ but I thought my many friends in Europe might wish to try a
challenge. Perhaps you can tell as many as possible to listen.

OK…here is a plan:
I will put WG2XFQ back on the air running the same X-Mass audio loop but add a
voice note that this is a repeat of the 2012 X-Mass transmission for those who
may have missed it. I will be QRV (on-the-air) at my local dusk (about 5pm or
so) and will let it run until my local sunrise on Jan 2nd, 2013 which will be
about 13:00z.
So please post this to the AM DX reflector as you see fit.
Same operating conditions:
486kHz
Heising AM
20W ERP
Antenna: Marconi-T at 70ft
Location: Forest, VA

Subject: Re: Your 486KHZ Station
Dave-
Feel free to cross post for me.
The station is WG2XFQ on 486khz running 20w ERP. QTH is grid FM07jj.
The exciter is a vintage home brew MOPA rig with a Heising AM modulator built
into the power supply. The exciter will produce a few watts of AM and I use a
modified Hafler audio amp to get the signal up to 200w of carrier power. The
antenna is my 160m dipole being feed as a real Marconi-T antenna with a base
loading coil and is feed against ground. Heising modulation is OK for negative
peak AM but rather poor with positive peak AM. The result is only about 40%
modulation if you keep to Heising's original design.
The purpose is to replicate the original Fessenden X-Mass eve transmission in
1906 where he read from the bible and played two songs on his violin. Fessenden
used an Alexanderson alternator around 50kHz, but today it would be so much
harder for people to hear anything but QRM at 50kHz, so went about 10 times
higher in RF freq.
This is the 2nd time I have done this. Plan to do the same next X-Mass too.
Upon request, I can run the audio loop again on New Years like I did year since
a few of the 600m gang were away from home at X-Mass and missed it. WG2XFQ is
QRT at this point.
I have also run the station on the Aniv. of the Berlin Treaty that helped
establish 500khz as being the international distress calling frequency. I have
also run the station on April 15th on the Aniv. of the sinking of the Titanic
but that ship used Marconi gear and all Marconi stations used CQD rather than
SOS as an emergency call. I run part of that loop with a sound clip of what a
spark station would have sounded like sending CQD. I made the FCC aware of my
use of CQD and no objection was noted as very few but real radio historians
know what CQD was used for and who used it!
The freq I used is not part of any potential ham band so there is no confusion
about this being related to the future 630 meter ham allocation.
