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.

Chuck-

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 2^nd, 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

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.

Onko joku saanut joulun jälkeen vastauksia?
