PD4KH Amateur radio - Koos van den Hout

I passed my radio amateur exam in March 2013 and I registered the callsign PD4KH (pappa delta four kilo hotel!). PD4KH on qrz.com

I am usually located around maidenhead locator: JO22NC

QSL policy for PD4KH

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 and hrdlog 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 QSL reports for QSOs.

2015-10-04 I participated in the Russian WW digital contest.. and it was bad
For a few hours I participated in the Russian world wide digi contest and it was near-impossible to get through to others, unlike the previous CQ worldwide RTTY contest. I only tried PSK63 mode. I did have a look at my contest macros and I will reshuffle them and improve them. I did notice the FLDIGI Contest - How To handles 'Search & Pounce' mode as something that 'also happens', but the 'Run' mode is thought out better. In 'Search & Pounce' mode you search other calling stations and try to answer them, in 'Run' mode you do the calling.

With my modest station I'm almost all the time in 'Search & Pounce' mode so I need to optimize my macros for that mode first.

Results were awful: I made a total of 17 contacts in about 1.5 hours of trying. I'll enter it as a checklog: verifying the contacts others made with me but not entering the scoreboard. It seemed almost nobody was hearing me, especially not in Russia, where the points can be scored.

Preliminary score:
Total number of QSO in your log is 17, Including 0 QSO with errors, Valid QSO - 17

2015-09-27 I participated in the CQ WW RTTY contest
Much of this weekend was filled up but I noticed really heavy RTTY activity on the radio bands Saturday evening. Looking at the PG7V contestcalendar showed me the CQ World Wide RTTY Contest 2015 was busy in full force.

I participated for about two and a half hours on Sunday between other things and managed a nice 54 contacts. It is a quite busy contest with lots of stations participating. There are probably 'contest stations' that participate for the full 48 hours and make thousands and thousands of contacts. For me only 'search and pounce' mode worked, nobody came back to my calling attempts. This is probably related to my modest output power and antenna setup.

Getting the log accepted was a whole different problem and in hindsight it was the wrong decision to try to get that done late Sunday evening. The logging format for this contest is quite strict (and somewhat US-centric) and it took me a few iterations to get the log right to have it accepted for processing. According to the documentation fldigi does the cabrillo export right for the various contests but I noticed some problems with it. On further reading I notice I have to set up the contest macros before I start logging for a contest. Which means I have to prepare a bit more for a contest than the usual "Something is going on, let's jump in". The fldigi site has a document FLDIGI Contest - How To which I should read and use for the next contest!

2015-09-25 New records for me in amateur radio
This evening I hung the endfed antenna outside, in the hopes of being able to make a contact with a station in Algeria I saw calling. But the station went away, or the signal doesn't make it to my endfed while being ok on my attic antenna.

eQSL card from YB6HAI But I received a very interesting reply when I called CQ for new contacts: YB6HAI from Indonesia. New distance record: 9923 kilometer. And a new country.

The contact is already confirmed.

2015-09-20 Better powersupply for the amateur radio setup
I got annoyed with the PC powersupply I used for the amateur radio setup, output power was dropping below reasonable values at any load. The PC power supply was supposed to be able to give me 40 Ampere at 12 Volts but I saw the 12 volts drop easily to below 10 Volts at a load of less than 10 Ampere. So, time for a better power supply. I kept an eye on any nice secondhand offers and found an Alan K205 powersupply for sale which would give me 13.8 Volts at a sustained maximum of 20 Ampere (22 Ampere peak). I made a reasonable offer which was accepted immediately and went to pick it up.

It's an old-fashioned transformer and regulator powersupply (not a switching mode powersupply), it's big and it weighs a lot. And it works like I want it, with voltage never dropping below 13 Volts even under heavy load.

This also makes the Yaesu FT-857 radio work better: under 12.5 volt it will lower the output power. I notice it now runs the output fan for longer periods after transmitting.

2015-09-20 More QSL cards
Radio amateurs exchange QSL cards to confirm contacts. Recently I received a whole batch of new ones. I usually look at the 'backside' first since that has the details about the QSO, but some cards have really nice fronts too!

2015-09-19 Radiocontesting can be simple and fun
I mentioned serious radiocontesting before where people invest serious time and money into getting the best scores. There is also a more laid-back approach of participating for a few hours in a radiocontest and just going for the fun. And maybe having a contact with a new country.

The Essex Hams did just that: they participated in the RSGB SSB Field Day and enjoyed themselves without breaking any records in scores, read the full report at RSGB SSB Field Day – Shoebury 2015 - Essex Ham. A nice article, and the main conclusion is that they had fun with amateur radio.

Found via Essex Hams try Contesting - Southgate Amateur Radio News.

2015-09-14 Trying APRS by car and bicycle
Today I took the APRS setup with me. During the day by car (it was raining) and in the evening by recumbent bicycle to the radio club (it wasn't raining that hard in the evening). Both times I had APRSDroid, the Mobilinkd and the radio running for APRS (Automatic Packet Reporting System).

Testing APRS, data received by network and presented by aprs.fi With the car the antenna was sticking up from the left rear window. Most beacons were received by a nearby APRS digipeater and made it into the APRS network.

With the bicycle the antenna was sticking up from the bag on the back. No beacons were received by an APRS digipeater. And I'm not too happy about a 5W transmitter right behind my head. Time to look at the setup.

2015-09-06 Participated in the Russian "Radio" WW RTTY Contest
On Saturday I participated in the Russian "Radio" WW RTTY Contest. I used the end-fed antenna outside to give me somewhat better reception. The contest is the whole of Saturday (UTC) but I only participated in the local evening time due to other things that happen on a Saturday.

The preliminary results:

2015-08-31 A serious thunderstorm counted
Lightning strikes 2015-08-30 We finally had a serious thunderstorm last night, making us almost jump from the bed at one moment. And the lighting strike counter saw that thunderstorm nicely.

It's quite clear the counts are lower now the sensor is closer to the ground. I'm not sure what to do to get a "good" count again. Last week I placed the 10/20/40m endfed antenna outside for part of the day and noticed that setup also influences the lightning detector in the shed. Raising the end of the antenna helped a bit, I noticed I can use the back gate of our house as the low end of the antenna.

2015-08-30 I participated in the SCC RTTY contest
This weekend I participated in the SCC RTTY championship. I did nothing special to my setup other than sitting down behind the computer and running fldigi in contest mode. Claimed scores: 33 contacts, multiplier 28 (claimed score 1876 points) in the single-operator 20 meter category.

I updated the Veron afdelingscompetitie with the latest results.
