QSL policy for PE4KH

I upload logs to eQSL.cc and ARRL Logbook of the World, during and after being active on the radio. I upload logs to www.qrz.com and clublog on a regular basis. I like paper cards via the QSL bureau so I send those out when requested or when I think the other party will appriciate one and I will respond when I receive a card. You can also request a card via the Log Search on clublog for PE4KH using the OQRS service. Notifying me via e-mail that you would like a card is also possible.

I appreciate SWL reports for QSOs and will respond.

The 'hamradio' items from my homepage

2019-03-24 Now also mapping 70cm gridsquares
In the past week I made my second 70cm FT8 contact, and again with another amateur in the JO22 gridsquare. So the map for 70cm gridsquares contacted and confirmed isn't very spectacular yet, but I'm going to generate and maintain it anyway.

Now in the list of maps at pe4kh.idefix.net.

2019-03-17 Still working and sometimes struggling learning morse
Every week there is an hour of morse training at my radio club, see article CW cursus op PI4UTR (Dutch). And I'm going there every week I can, as learning morse is an important part of my amateur radio resolutions for 2019.

We're training with the G4FON morse trainer which uses the Koch method (order of characters to learn) to learn morse and so-called Fairnsworth timing (playing the dits and dahs of the characters at the high speed but leaving room to think about what you just heard).

I am doing ok, now we're getting to the level of 37 characters I have a hard time remembering the newest characters. Constant exercise seems the only way to fix this a bit, making exercises with just the characters I keep making mistakes in, although I can go blank again on new characters when switching to testing the whole set. As soon as I get reasonable low amounts of errors I'll try to raise the speed (by raising the effective speed, the dits and dahs of a single letter still come at 15 words per minute).

I want to learn this, with the plan to pass the Belgian CW test some day, and get up to enough speed to be able to participate in morse parts of contests and DX contacts. But there will be a lot of practice before I'm at that level.

2019-03-13 My lineup of amateur radio related podcasts
I like hearing about other experiences in amateur radio from around the world. Podcasts are an easy way to hear experiences, news and opinions from other amateurs. And they fit nicely into my daily commute.

The list of amateur radio related podcasts I follow:

2019-03-11 I participated in the EA PSK63 contest 2019
PSK63 contest in fldigi This weekend was the EA PSK63 Contest and I participated Saturday evening, Sunday morning and a bit Sunday afternoon. I planned to participate in this contest so I set up the endfed antenna outside Friday evening because I would be away most of the Saturday daytime.

With the current radio propagation and a serious part of my participation after sunset I decided to enter in the single operator 40 meter category. I made 106 contacts, with 25 different spanish provinces in the log (out of 52 possible province codes). Spain by itself has 50 provinces with Ceuta and Melilla not counting as a province but they do count in the contest.

I also participated in the EA PSK63 contest 2016 with 60 contacts and EA PSK63 contest 2018 with 125 contacts (but only 79 in the 40 meter band).

2019-02-17 Sunday ISS pass with good results
Slow Scan TV transmitted from the International Space Station by Koos van den Hout PE4KH 2019-02-17 Slow Scan TV transmitted from the International Space Station by Koos van den Hout PE4KH 2019-02-17 Slow Scan TV transmitted from the International Space Station by Koos van den Hout PE4KH 2019-02-17 Sunday had less time to be at the radio for ISS passes but one pass was ok. It started with the end of one image, one full image and the start of the next image. The audio recording of the whole pass is included.

2019-02-16 One more ISS pass with good results receiving slow scan TV
Slow Scan TV transmitted from the International Space Station by Koos van den Hout PE4KH 2019-02-16 Slow Scan TV transmitted from the International Space Station by Koos van den Hout PE4KH 2019-02-16 After hickups in recording audio from the radio on two previous passes I rebooted the whole system (it was nagging about a reboot anyway) and I received two more partial images.

Thanks to ARISS Russia team member Sergey Samburov, RV3DR for making this possible!

2019-02-16 Second ISS SSTV pass: more results
Slow Scan TV transmitted from the International space station received by Koos van den Hout PE4KH on 2019-02-16 Slow Scan TV transmitted from the International space station received by Koos van den Hout PE4KH on 2019-02-16 Second pass of the International space station gave me one partial picture and one complete (with some noise).

2019-02-16 Received SSTV from the ISS
Slow scan TV transmitted from the International space station received by Koos van den Hout PE4KH on 2019-02-16 In this weekend there are extra slow scan tv (SSTV) transmissions from the international space station (ISS). The ISS moves across the sky when viewed from earth so I calculate beforehand when it will pass across the sky and what the trajectory will be.

I woke up in time to be outside for the first one. A low pass over the horizon and most of the pass matched a pause between transmissions, so not much image received.

2019-02-01 Plotting the number of amateur radio contacts after a contesting month
QSO count plot up to January 2019 After a month with three digimode radio contests I plotted the number of amateur radio contacts again. The number of contacts is clearly higher each January as a contest month, with this January a new peak.

The contests were the ARRL RTTY Roundup on 6 and 7 January, the UBA PSK63 prefix contest on 12 and 13 January and the BARTG RTTY Sprint Contest on 26 and 27 January.

Nicer looking font due to the upgrade of "radio workstation" thompson. I guess even gnuplot is coming along with the modern times.

2019-01-27 I participated in the BARTG RTTY Sprint Contest
RTTY contest on websdr This weekend I participated in the BARTG (British Amateur Radio Teledata Group) RTTY Sprint Contest.

I went into this contest with the idea of maybe getting some contacts and things turned out somewhat better than that: I made 82 contacts. No new countries or anything else special. The one that got away was PJ4P, Bonaire. I saw that station calling and I kept answering but the contact did not happen.

I used the topendfed antenna outside and the amplifier. So I entered in the high power category.

As with other recent contests the propagation wasn't cooperating very well. When I started in HF at home (October 2014) I would switch from 10 to 20 meters after it got dark because of the changing propagation. Now I change from 20 to 40 meters as soon as it starts to get a bit dark.
