From DX with Love – RDXC 2017

In a further example of the benefits of DX contests for those looking to rack up new countries, this weekend’s Russia DX Contest served up another bounty of new DXCC entities on CW.

All in all, I landed 11 new DXCC entities. Since part of the fun of contesting is imagining the operator at the other end of the ionosphere – doing the same thing you’re doing, furiously decoding CW in front of a radio, thousands of miles away – I’ve included the names of the ops below where I could find them:

  • Switzerland (HB9ON – Radiogroup in Piancamara 7, a profilic DXpedition team)
  • England (M2G – not a special event station, just a contest call of John in the UK)
  • Croatia (9A7V – Eugen)
  • Poland (SN8B – Bobowsi)
  • Germany (DA0AA – A radio club in Germany. “Emergency Radio Station Frank Cut Switzerland”, says Google Translate…. so that’s something)
  • European Russia (RU1A, a contest station out of St. Petersburg)
  • Northern Ireland (MI5I – Colin)
  • Serbia (YT3X – Miki)
  • Sweden (SH1DX – could not find)
  • Argentina (L6HKA – could not find)
  • Slovenia (S51J – Janez)

A bevy of new European countries worked during RDXC 2017. Argentina can come too.

I also connected with a second Alaska station, my first AK contact on 20m, which should help to cement that state for my WAS goal this year. (To be sure, KL7/VE7ACN has been tearing up the bands this week, since I heard him a week ago. But more contacts in the log never hurt.) As icing on the cake, I heard, but couldn’t contact, Arthur 4X2M in Israel . Still searching for that first elusive contact in Asia.

Unlike the ARRL DX contest, where contacts within the same country don’t count for anything, the Russia DX contest does award a (small) number of points for contacts in the same country. So I picked up a few stateside contacts on 40m later in the evening, just to add to the contact count and continue drilling my CW.

There’s a joke in radio circles about “contest propagation”, which is the notion that even when “the bands are dead,” they somehow “magically open up” when there’s a contest going on. Certainly, during major contests, when everyone who has one brings out their big amplifiers and aims their beams most precisely, contacts are more frequent.

But this weekend, I suspect that the ol’ ionosphere was actually on our side for a change – in the late afternoon, after I’d worked what there was to work on 20m CW and before 40m opened up, I dipped over onto 20M JT65. . After noodling around for about 20 minutes, I had landed both PD7RF (Frits in the Netherlands) and MC0CSO in Wales.

Two more DXCC in the log. That brings me up to 49 DXCC entities reached, with 30 confirmed.

And as a final sign of Sol’s grace upon the upper atmosphere, the following afternoon I heard (but could not reach) both Asiatic Russia (RA0CGY) and Japan (JM7OLW, JH1HRJ, JA1PSS, and 7K4GUR) on JT65.All are over 6000 miles away. They were way below the noise floor at -20 to -24 dB, about the limits of what JTDX will decode. But things look promising as the summer months move closer.

Firsts: 17m, Brazil, JT65

Earlier this week, I achieved two firsts in one QSO: my first contact on the 17m band (a  100Khz slice of spectrum starting at 18.068 Mhz), and my first contact with Brazil. Specifically, with PY6JB, JOÃO, in Salvador, Brazil, nearly 5000 miles Southeast of me. I’m not positive, but I think this marks my furthest contact on the air so far.

That I set a new personal distance record with JT65 is not surprising – the mode is designed for weak signals and long distances. It encodes up to 13 characters into a highly compact format of 72 bits. These are then run through a pair of Reed Solomon encoders, which translate the user data into a set of 126 bits for transmission with significant potential for error-correction. Reception of signals more than 20 dB below the noise floor is not uncommon with JT65.

As you can see in the screenshot of the popular JTDX program by UA3DY, even transmitting at around 35 Watts, my signal was still 17 dB below the noise floor by the time it got to Brazil. But that was enough to exchange callsigns and reports, and officially verify the QSO.

So, another new country in the log, and my first ever contact on the 17m band. Not a band way to spend a Monday afternoon.

Hear you on the air!

*UPDATE: The same afternoon I posted this, I made another contact with Brazil, but this time on CW – PV8ADI! Woohoo!
