I passed my full radio amateur exam in March 2016 and I registered the callsign
PE4KH (pappa echo four kilo hotel!).

I am usually located around maidenhead locator: JO22NC
I upload logs to eQSL.cc during and after being active on the radio. I upload logs to ARRL Logbook of the World, www.qrz.com on a regular basis. I like paper cards via the QSL bureau so I send those out and I will respond when I receive those. Notifying me via e-mail that you would like a card is also possible.
I appreciate SWL reports for QSOs.

I am planning to participate in the SCC RTTY contest 2016. I participated in the SCC RTTY contest 2015 as PD4KH within the limits of my novice amateur call. It depends on the local noise levels whether I will end up in the single operator 20 meter, single operator 40 meter or single operator all band low power.
I decided the picture of the recent outdoor activation was nice for a personalized eQSL design. It took some serious work with Gimp to make it turn out like I want it, and that was just with one image to work with and I'm still not completely satisfied. In the result will be an overlay at the bottom with the details of the contact. I used the Kenteken generator by Remco van Zuijlen to generate the callsign image.
On wednesday everything in our house was switched off due to some electricity work. I prepared for this and made sure the radio was connected to a charged battery. And the end result was that the noise levels around our house are at least the same when power is out. In the 20 meter band I noticed even stronger carriers which may be caused by the fact that the local VDSL modem was powered off at that time. I made one contact which I logged on paper with OE2YOTA the youngsters on the air camp in Austria. I guess I will have less noise when the power fails in a wider area, as reported at This is what HF sounds like during a power outage at my QTH!
Again another weekend in which I had some time for digimode radio contacts and digimode contesting turned out the best way to get a high number in the log. There wasn't a lot going on in the 20 meter PSK31 band so I listened in RTTY and found the activity. This was the weekend of the Digital Modes Club RTTY Contest 2016. Propagation and local noise weren't cooperating a lot but in the end I made 62 contacts. I set my contest category to SOAB-LP-12h: single operator all bands (although I only made contacts on 20 meter, but this contest does not have categories per band), low power (less than 100 watts), time limited to 12 hours (I operated less than 12 hours and had a good nights rest). Interesting results were a new country: Saudi Arabia, I made a contact with 7Z100. No USA contacts this contest, which I usually expect in a RTTY contest. I used my fldigi digimode contest macros without any modifications and they worked fine. Calling CQ yielded zero contacts, everything was done search and pounce style.
I recently came across another spot that looked very good for outdoor radio operations. At a bend in a road near Maartensdijk is a nice spot with a number of trees and a table. So when I had some time I hooked up a trailer to my recumbent bicycle, loaded enough radio gear to make some voice (phone) contacts and went over there to give it a try. It is a nice spot, located at JO22ND88SW. Not a lot of trees so it got quite windy. Radiowise the 20 meter band was completely free of interference: I managed one contact with TA1BX/M and my honest signal report was 5-by-0: radio quality 5 (good understanding) and signal level 0: the meter on my radio did not move. He gave me a 5-by-5 report. I heard several other stations that did not hear me due to the bad antenna situation (part of the endfed was on the ground) or due to the pileups they caused. I set my HF output power to 50 watt to get out a bit, this did not drain the battery too fast. Things I brought along: radio, antenna cable (RG-58 cable, not as good as Aircell-7 but a lot less weight), BNC to PL259 adapters for the cable, the endfed antenna, two charged 12V batteries, headphones, a tablet computer for logging, nylon rope and a filled waterbottle. Things I can improve for next time: throwing the rope for the antenna into a tree (it took several tries to get a somewhat acceptable height). And I looked into logging on paper, logging on a tablet was not very comfortable. Maybe logging on old-fashioned paper can be the solution, I found some nice templates at Amateur Log book templates. I printed a few of the 'mobile' template and I will try those next time. Update: The locator was JO22ND88SW and not JO22ND88RU. At this resolution it does matter when the GPS application says the estimated error is 88 meter.
Checking around the bands where I can do PSK31 I noticed actual activity on 28.120 MHz (10 meter band) and had a contact there with IZ8OYV. Just one answered CQ and no other contacts. The sunspot cycle is clearly past its peak with days without any active sunspots showing up, and this lowers the maximum frequency at which radio propagation in the ionosphere happens. So currently a 10 meter contact is very rare where the first HF contacts I made at home in August 2014 were all on the 10 meter band. Update 2016-07-11: And two more 10 meter contacts in the log.
The new and improved QSL card workflow I thought about in April has come true. In the mean time I bought printer labels and this evening I took my time to work through the last (at the moment..) outgoing QSL cards for PD4KH and printed labels for them.
Update 2016-06-27: A bit of searching found me A Slashed-Zero Droid Sans Mono - cosmix.org. Downloaded the zip file, unpacked DroidSansMonoSlashed.ttf in /usr/share/fonts/truetype/droid and it was available to glabels instantly. And I printed the first labels outgoing QSL cards for PE4KH and now this new workflow is saving me time. I decided to keep using my 'old' PD4KH cards with a small label updating the callsign. Now I am actually saving time!
- Changing the exported fields in CQRLOG changed the field numbers in the CSV.
- CQRLOG export csv files have no newline at the end. I combined two selections (send via bureau and send via manager via bureau) and it took me a while to note one QSL missing.
- CQRLOG default is to export just the band. I like having the frequency on my cards.
- Fiels exported: Date, time on, Callsign, Freq, RST Sent, QSL manager, Comment, QSL PSE/TNX
Last night a serious lightning storm passed and it got counted, but clearly with the same problems in counting as seen before in counting thunderstorms from the shed while radio activity causes a lot higher counts. Looking at the graphs for thunderstorms counted from the attic before I was active on HF radio there is quite a difference in numbers. I think I want the lightning strikes counter back up in the attic but with a low-pass filter somehow to filter out false counts from amateur radio traffic.
In almost every digimode contest I improve my contest macros a little, so I decided to share them. Credit goes to FLDIGI Contest - How To for a lot of the initial inspiration and Choosing your basic macros - VA2UP RTTY Contesting which has the really minimal approach, and this helped me with finetuning. This will be a quite long post only interesting to a very specific group! Digimode is the name for all radio modes in which digital information is exchanged and a computer is used to encode and decode the digital information into something the radio can work with. Digimode contesting for me includes RTTY and PSK63 contesting, there are other modes used in digimode contests.
Without a lot of preparation I participated in the 2016 Ukranian classic RTTY contest contest just to see how I would do and maybe get one or two new interesting entities in the log. The radio interference was active all weekend on 40 meter so I participated only on the 20 meter band. In the end I participated for about just over 3 hours and made 64 contacts. Interesting new entities were Venezuela (new country) confirmed, Pennsylvania confirmed and North Carolina confirmed (new US states). Confirmations come in quick via eQSL and LoTW! I updated the Veron afdelingscompetitie with the results. And all the other usual places where I upload the logs of my radio contacts. Already the first confirmations via eQSL are coming in and visible in my eQSL received at PD4KH / PE4KH collection.
