• Portable preparation

    Preparing for some portable operation. Ogling an activation of POTA PA-0181 (2,5km / 1½ mile by bike) and/or PAFF-0079/PA-0180 (5,6km / 3½ miles), my wife PD4LYN and I decided to test the new equipment in the field.

    Our /P setup under test

    • TRX: ICOM IC-705;
    • Battery: 13.2VDC 12Ah home-brew LiFePo4 pack;
    • Antenna: Diamond RHM-10 with PL socket; mounted at the back of my bike with a SO239 gutter mount;
    • Amp: 45W MX-P50M, when QRP is really impossible due to abysmal condx, trying to output about 25W at most; seldom used nonetheless;
    • Keypad: for easy voice or cw-keying; simple, home-brew pad, needs some reworking;

    • PC: Asus Transformer T100TA;
    • Tuner: mAT-705, not needed, but you never know;
    • Paddle: Pico Paddle;
    • A couple of coaxial cables.

    We noticed some heavy RFI originating from the USB between the IC-705 and the mini-notebook. Previously, with the microHAM USB III, I did not have this problem, so I (wrongly) assume this is a combination of transceiver, USB-cable and possibly some coaxial common mode going on. It messed up the RX and, as we later found out, RFI from the TRX also messed up USB. Quite predictable.

    Next time I will try:

    • a decent RF-choke;
    • a variety of properly double shielded USB-A-to-micro-B cables of different lengths with ferrite core(s);
    • a separate ferrite clamp of decent quality to run the USB-cable through;
    • changing the position of the antenna relative to the transceiver;
    • warmer weather! It was sunny, around 15ºC (60ºF), but a harsh wind in open land made it very uncomfortable.

  • Fast Forward a ‘few’ years…

    Well, this is awkward. I haven’t been updating this blog for years.
    I have just started updating my QRZ.com pages… again!

    A few important announcements:

    • April 2020: got active again from my home QTH after a few years portable-only. I now have a decent antenna tower with antennas for both HF and VHF/UHF including a proper 2m/70cm yagi.

    • February 2021: starting to upload last years (!) of /P logs. Converting them from paper with Fast Log Entry. At first, I was a bit sceptical (it felt a bit too ‘elite hacker/coder’), but I really enjoy it now: around 100 paper log entries were converted in just under 15 minutes.
    • Refreshed my /P setup with a nice ICOM IC-705 and all the necessities.
    • Also started to get interested in WWFF and POTA activations in the open air. Do check out PA6ML/P on QRZ.com for a schedule for this year.
    • Special Call Sign PA6ML: My XYL (PD4LYN) and I started a special callsign station on the 28th of February 2021. Do check out the PA6ML & PA6ML/P QRZ.com-pages on the Special Callsign Station for 2021 for schedule announcements.

  • Trip to Newcastle


    In the weekend of the 16th of February I made a one-day trip with my YL to Newcastle, using the ferry of DFDS (Danish Seaways), in this case the King of Scandinavia. After an inquiry at the service desk and a ‘ok’ from the captain, I prepared to use the FT-817 on the stern. First a qso on the repeater of Amsterdam on 70cm: PI2ASD. Strong, clear signals from the repeater and a nice qso with PA3CNT.

    On the upper stern post, there was a abandoned (probably due to the bad weather) terrace. I used it to make some nice /MM contacts on HF. Unfortunately, due to QRM from my laptop via the USB cable to my microHAM USB 3, I had to stop the experiment with WinLink. And RFI made my 817 TX and stop with a couple of milliseconds. Back to the drawing board and use some rigid toroids on the USB cable!

    On the way back, I overheard a qso between two British hams on 2m in FM. I successfully managed to enter the conversation and spoke to Sid (MøZID) and Derek (sorry, lost your call there!).

    Half an hour or so later, I tried again (assuring the new LiPo battery pack for the 817 from Windcamp was still okay). This time I tried a cq on 144.300 in single sideband. And voilá, MøTLX, David, answered my call soon after. With only 4 Watts (according to the specs) and by now a distance of about 50 (!) nautical miles. Very nice indeed!

  • Jamboree On The Air 2013

    For a few months I have been thinking about participating in the JOTA/JOTI event of the Dutch Scouting (Scouting Nederland). A couple of weeks ago, I decided to write an e-mail to the national coordination centre of the JOTA/JOTI. Due to pure coincidence, they managed to find a group in Harmelen, only a 25 minutes ride from Gouda. The group was eagerly searching for a radio amateur. And they got one! Armed with a load of equipment, I got in the car to the Scouting group Willem-Alexander. They had already built a very nice scaffold of around 25′. It was a very busy, crowded and fun weekend and we made a lot of contacts both on 2 meter FM/SSB within the Netherlands and on HF with numerous stations.

  • BrunchFox / ARDF event N.R.V.

    For the N.R.V. (Dutch Fox-hunt Organization) and the ARDF community ZCV Keistad, we organized a nice event in the center of the Netherlands, near the town of Lage Vuursche. The fox hunt consisted of two foxes, which had to be searched by car, followed by a ARDF on foot. Of course, we did some DX on several bands too, using the HyEndFed antenna.

  • Charlie Quebec Field Weekend

    Another short post concerning a nice field weekend organized by the Charlie Quebec DX Group. Throughout the day, the weather was great, but in the evenings the temperature dropped fast and huge condensation threatened the equipment. Fortunately, my new case for the FT-897 and accessories protected the stuff quite good 😉

    Overall a fine two days!

  • Whisky Oscar Field Day

    In the same weekend as the two radio fox hunts from the RandstadVos, on Saturday the 7th of September the Whisky Oscar DX Group using the call PI4WO organized a field day in which I participated as they needed more fully licensed radio amateurs 😉 Some very nice DX contacts were made: Asiatic Russia, near the Bering Sea, China, Japan and some other distant countries.

    TRX: Kenwood TS-590S @ 100W.
    ANT: Fritzel FD-4 for 10, 15, 17, 20, 40, 80 meter band (even a decent SWR <1.1 on 6 meter band!) // Solarcon IMAX 2000 vertical antenna for 10,11 and 12 meter band.

    Setting up the equipment.
