In the last 2 weeks I have been working hard to get my band decoder up and running and to prepare for next contest: the ARRL RTTY Roundup (in which I placed first in M/S LP non W/VE in 2013).
Yesterday I made some QSOs and everything worked all right.
This morning I click on a dxspot on 12m and have my logging program turn the rotator… a few seconds later: no more signal on the receiver.
Something has gone wrong on the Big Boy Rotator and, of course, before I noticed it had overturned and broken the coax cables for my WARC rotary dipole.
The 10-15-20 beam is working OK and the rotator seems to turn but with no correct indication of the direction. I guess this contest has already ended for me this time.
Next big RTTY contest on my list is WPX in a months time…
– find someone to climb the 15m tower twice
– fix the rotator or find a new one
– fix the broken coax
Anyone some money to spare to help me buy a SteppIR DB-18E so I can replace the good old FB-33 while we’re climbing the tower anyhow?
The news is… there is no news. 🙁
On august 30. I received an e-mail from Appellofunk (the dealer where I bought the triplexer) stating: “if you like please open the TriPlexer to see what happend.”
So that’s what I did and that same day I sent them pictures of the inside of the triplexer showing at least 2 burned (probably more) SMD capacitors.
Since then, no more news.
E-mail between Germany (Apellofunk) and the US (Inrad) must be going by boat I guess…
My new contest secret weapon worked very well… for exactly 1 QSO.
For the moment I have only these (permanent) antennas for contesting: a Fritzel FB33 3-element tribander at 16m and homemade inverted V dipoles for 40 and 80m at 15m.
So for SO2R I have always used an extra Fritzel GPA404 vertical for 10-15-20-40m. But to avoid the hassle of installing this antenna before the contest and taking it down after the contest I recently decided to purchase an Inrad HF Triplexer so I could use the FB33 on 2 bands simultaneously.
Last week I had the specs of the Triplexer tested by Luc ON7KZ and all seemed to match the specs as in the Inrad web page.
I installed the triplexer between my Sixpak and the FB33 the day before the contest but I didn’t have enough time to thoroughly test it. (I did check all connections twice though!)
Once the SCC Rtty championship started I made a S&P QSO on 20m and during the QSO I saw the SWR on 20m going up to alarming levels :-(.

Wow, my previous post (EU189 even 2 dxpeditions planned!) is only 3 hours old and Google already picked it up! WOW!
A few days ago I found a nice piece of software on the internet: BoxCar 2D. This is a way to design a car using a genetic algorithm: a population of cars is created at random and then tested on a track chosen by the user. Then the best cars ‘mate’ to get a next generation. Together with a set mutation rate the cars improve over the generations.
Warning: watching this is addictive, it’s far better than television!
My programming skills are rather limited but I wondered if someone maybe could design antennas using one of the (mini)NEC engines and this genetic system?
Update: it seems that this is not such a new idea, at least for developing antennas. A little googling for ‘genetic algorithm antenna’ gave me some 160000 results 🙂
SuperNec seems to be great software for this but at $6080 it seems I’ll stick to Eznec and MMANA for a while.
Those who know me know I’m not very good at morse code. But I still have great respect for those using it regularly.

In spite of all the answers the internet has given us, its full potential to transform our lives remains the great unknown. Here are the nine key steps to understanding the most powerful tool of our age – and where it’s taking us.
