Welcome in the WPX Honor Roll
I noticed that I’ve reached 600 different call prefixes so far. While 400 is enough to get your WPX-certificate in the Mixed category (I don’t have one, DXCC is much cooler), with 600 different prefixes you’ll enter the WPX Honor Roll. And that’s a nice signal to receive: get listed with the other ‘top’ stations …

And thats DXCC 125 confirmed
Direct QSL today. C31CT confirmed his 3 QSO’s on 3 bands in 2 modes. That makes the 125th confirmed DXCC. Tough I’d rather see a LoTW confirmation it’s nice to see the numbers rising. Now let’s work towards 150. The QSO’s are already made, but 26 DXCC is still unconfirmed.

Build your own Hytera cable
When you own a Hytera DMR transceiver you need an optional cable costing 35 euro to program your transceiver and/or to upgrade the firmware. In my opinion, programming cables should never be an option. You can spend the 35 euro to buy one, or spend about 5 euro to make one yourself. The self-build version …

Hytera X1p: First impressions
I’m currently testing the Hytera X1p portable DMR-transceiver. The first thing you’ll notice is the size. The transceiver is small, just like an iPhone 5. With the standard battery the portable is only 21mm thick. Still, the set has a full keypad and nicely coloured display to show the status, channel, battery level, etc. On …

De PLC het zwijgen opleggen
This article is in Dutch and shows how to silence your neighbours’ PLT and lose the irritating noise on HF. PLC’s, een vervelend verschijnsel dat tot behoorlijke irritatie leidt bij zendamateurs die hun HF-spectrum vervuild zien raken met carriers gemoduleerd met CAM-modulatie hetgeen vervelende ratels tot gevolg heeft in een groot deel van ons HF-spectrum. …

Adjusting Cavity filter
Today I’ve been working on the Cavity duplex filter for the new DMR-repeater. The exact frequency is yet unknown but I assume it will be 438.3125 MHz for the output and 430.7125 MHz for the input, which makes a -7.6 MHz shift. I’m the lucky owner of a Rigol DSA815 Spectrum Analyzer (9 kHz – …

Preparing DMR-repeater
I’m busy preparing a new DMR-repeater. The exact location is unknown but having a look at white spots in the coverage maps from the current repeaters most-likely it will be somewhere in the Northern part of the Netherlands. The repeater is the Hytera RD985 so it will join the HYT-network. Currently there are 3 options …

New QTH, new shack
Today Lucas (PD0LVS) and Ron (PA4RVS) drove to Hoogland to view my new house and helped me out to put the loop back on the tripod in the garden. The hours before I was busy unpacking my equipment to build a new shack. All the basics are there and the big question was: How was …

Going digital with DMR
After D-star there is DMR. Not that I’ve used D-star much but just want to give new techniques a try. Yesterday I’ve ordered a Hytera MD785G. This is a mobile UHF-transceiver for both analogue FM and DMR. Ideal as a second set for the local repeaters since the 2nd VFO of my Icom IC-9100 is …

Shack cleaned
We will move over to a new house next month, so time to clean up the shack. New QTH will be Hoogland (Amersfoort) as of half October. All antennas are indoor for the next two weeks, including HF via the loop.

Got loop?
After weeks (months) I finally found some time to test the Wimo / I3VHF / Ciro Mazzoni loop-antenna for the 40 till 10-meter bands. First QSO was with UA9MMC in JT65 on 20-meters, resulting in -13dB reports.

2nd place during Dutch CW-contest
Oldie, but still nice. I’ve earned the 2nd place during the Dutch ‘PA-beker’ contest end of 2012 in the category ‘Novice CW’. Only two people send their log but still, 2nd place sounds quite okay 🙂

Just passed my HAREC license
It’s more than 15 years back since I did exam for the Novice license. Today I took the shot to go for the Full/HAREC exam. Totally unprepared I passed the exam with 11 wrong answers, where 15 is allowed. So I passed. Finally access to WARC and the 6 meter band.

Let’s go SHF
Marcus, the owner of Hamshop.nl, offered a used Icom UX-9100 module for 23cm which I bought yesterday and arrived today. Now my Icom IC-9100 has all the (internal) options available. Let’s go SHF.

PG13IOTA QRT
The RSGB IOTA contest for 2013 is over. This year we activated the island of Texel (EU-038) as PG13IOTA. It’s very nice to operate in an environment without man-made noise. In particular on the 40-meters band, where the average noise level from my home is S9+, which makes local QSO’s even hard to follow. Nice …
