New
Got my QCXmini kit from QRPLabs and finished it. So I added a complete building report (incl designs for the tilt-feet) on this page.
A few owners of the new NanoVNA H4 have requested me if I could re-design the PCB so male SMA edge connectors can be used to directly connect the adapter PCB to the NanoVNA H4. For a while I holded it off, but recently I got my hands on a used NanoVNA H4 which I'm very happy with because of the bigger screen (yes my eyes aren't getting better). I started to use the H4 and wanted a dedicated adapter for it. So I measured my NanoVNA H4 and it has a distance of 39.5mm and comments from other OM's indicate that it's quite constant +- 0.1mm.
So I made a copy of the original design and changed the board layout to fit our needs.
I have added 2 pages to the Tools and parts section of this website.
A rebuild of the K7QO noise generator and a new Dual tone audio oscillator
For RF applications, one of my favorite ways to build is the ManhattanStyle and I have build a lot of these circuits in mint tins. One thing I'm always struggling with are the 9V batteries holders and on/off switches. So I 3D designed and printed this 9V battery compartment with room for 1 or 2 common cheap PCB push button on/off switches (they come in lock and momentary versions). continue reading . . .
Recently I found a page which described Roy, W7EL, Lewallens Simple & Accurate Directional Wattmeter as it was published in 2/90 QST. Searching for more information I noticed that W1REX - QRPme also has a updated version of this Simple & Accurate Directional Wattmeter.
I re-ordered the website to have a special kitbuilding section. Check it out : link.
I added a new for sale page on which I list left-over PCB's. These PCB's are sold at cost price (excl shipping).
As of 30 Juli 2020, I'm starting to sell my kits and assembled products on TIndie to see if that works out for me.
Check out my store :
Book the weekend of August 8 and 9 in your agenda for this event.

When people buy one of my PCB's, kits etc. I ask then if they send me a picture when they build it or using it. Below you find images some OM's send me.
So check out the Customer Gallery.
Once in a while I've been asked which tools I use for my hobby (both ham radio and model railroad).
On this page you find a list of tools I find use full.
I had a few QRP-labs lowpass filters and bandpass filters kits laying around and because I had nothing better to do this afternoon, I fired up the soldering station and assembled them. After that they need to be tested and tuned.
Due to the Corona (COVID-19) virus my employer asked us 2 weeks ago to work at home (when possible) to prevent spreading it. This would initially be until 6 April 2020, but I was expecting that it would be longer. So I had to setup a descent home-office.
Today I used a new theme on my website because the original one (Simplex) was responsive but the menu's where almost impossible to navigate on a mobile device.
I will look into that in the near future, but for now I switch to a more old-fashing (non bling bling) theme which atleast works on mobile devices.
While doing the dishes I listening to the Soldersmoke postcast #218 (one of my favourite hamradio podcasts). I heard Bill talk about his HI-Per-Mite CW filter in his uBitx and said that a ham in Belgium home brewed a HI-Per-Mite CW filter for his uBitx and shown the video on the blog. Curious about the video I look at the Soldersmoke website and found out that he meant me.
I may not from Belgium, but being linked on a blog / podcast which inspires me a lot, how cool is that?
My hosting provider has finished the most migrations to a new platform. After dumping the cache of this CMS and re-generate the pages (got 500 results), everything seems to work well.
For a few years I have been hunting to get a Yaesu FRG-7 (in a reassemble state and for a reassemble price) and because of the Wadley Loop system and the absolute great vintage design.
I have been staling it for many years, but this month it just has to happen. My hosting provider send me a e-mail that within a month they will be migrating there servers and due to a few platform updates (PHP, MySQL, etc) the (very old but stable) version of CMS isn't supported any more.
Today I took a few hours to do some re-organizing my website (dumped a few old pages and merged a few) and adding content about 3D printing and my 0 gauge to it.
A hamradio horror story about a interference problem a local OM Gerald PA3GEG had when his neighbor installed a big lot of non-certified LED tubes to save some money on his electric bill.
Hoe zonnepanelen een stoorzender kunnen zijn voor deuropeners, babyfoons, digitaleradio of tv, portofoons etc.
My friend and fellow Geek @daveborghuis has started up a cool workshop with 3D printing, lasercutting and foil cutting equipment. Also he gives courses on how to do that equipment and make cool stuff yourself. But thats not all, he also gives coures reagaring Arduino / Lilypad (a wearable Arduino) and custom courses for companies for introduction or as a cool teambuilding event.
The next course will be workshop lasercutting with inktscape how cool is that?

New mod for my uBitx. I build a HI-PER-MITE 200hz width active audio CW filter which is designed by David Cripe, NM0S (check out the interview with him on QSO Today). The schematic and working is published on the HI-PER-MITE page of the Four State QRP Group.
Because I broke my utc clock the "GPS clock with multidrop databus" project was activated again. From the spareparts I had on stock the first steps are made.
Nearby lightning discharge and a LoRaWAN Gateway aint a funny thing.

ubitx.net added blog post about my mods. How cool is that :-)
After to much things come in between I finally made time to start boxing up my ubitx.So it's time to get to work in the workshop. The first I made was a support for the PCB so I can remove the bottom and get direct acces to the PCB. Then it was drilling time.
Or a 0 gauge papersize diorama on a A4 standard piece of paper with the size of 297 mm x 210 mm. Continue reading . . . .
But then the word was said in the postcast that Ashhar has released a new uBitX radio not as kit or just the schematics, but as a ready to experiment module for 40m with a simple VFO for a remarkable low price (just $109 incl shipping). So then things got interesting and in the second week of December 2017 I orderd it and the waiting begun.

As many of my website readers know is that I like to build stuff my self and for that I have worked the last 30 years in variouse modelrailroad scales like N, HO, IIm & IIf. But sometimes you have to change to get new inspiration, so when I got my hands on some very nice Lenz Spur-0 freight cars, the idea about a new indoor modelrailroad was born. Read more . . .
Loving the kits from QRP-Labs, I knew I wanted to buy and build a QCX CW tranceiver the moment Hans Summer announced it. So when it he put it in the QRP-Labs shop I didn't hesitated for a moment and ordered the 40m kit. Read more . . .
Got my self a BitX40 module.

2m Preamp
I had plans for months now to build a 2m preamp based on a schematic from SV1BSX a 2m VHF preamp with about 18dB gain (for the schematic checkout this link). Last month I had worked out the component layout for the PCB and recently I had time for a realize this afternoon hamradio project. . . . read more . . .

After a busy week I had to have a "get my mind of the some matters" hamradio project. So I looked in my "nice gadgets and stuff for small projects" and found the TTP224 4- Channel Digital Touch Sensor Module's I bought a few months ago on a hamradio event. Read more . . .
As long as I have my Yaesu FT-301 the hunt was on to get a external VFO for that beautifull rig. Unfortunatly that thing is very hard to get, so when Hans Summers stared to sell his Ultimate Arduino Shield kitt on QRP-labs.com idea's were forming in my mind.
Added a new mod page : Z817 BNC mod
and a information page : So NO to UHF Connectors
Enjoy the reading.
Added a new walk to the Field reports page : 2015 November walks and 2 new project to the project page : Small portable HF PA and Digimode box
Seeing variouse SSB QRP transceiver designs on the internet I have been thinking about building my own QRP SSB transceiver for almost a year now. You can start from scratch but also for starters buy one of the many kits availible from variouse supliers like Pacific Antenna/QRP Kits (Hendriks), YouKits, etc. which can be just a bag of components and a PCB, to a more just montage kind of kit like the kits from Elecraft.

Are you a amateur radio operator with a passion for portable operations outside?
Then be sure to check out the Field Radio group on Facebook or there website at http://www.fieldradio.org/, both founded by Joe K9ATG. There you will find lots of other likeminded ham operators, get inspiration for great idea's, can read field radio stories (often including great pictures) and offcourse find lots of information about fieldradio.
I have thought about it a long time, but this week I made the call.
I want to experiment with SDR in the shack. It all starts here . . . (read more)
Although my Ultimate3 was had a nice housing, a few controls where on the back and ther wasn't much room for additional stuff to be added. With that in mind I didn't hesitate a few months ago when I had the opportunity to get my hands on a batch of nice modular metal plate housings which are by design excellent for filling up with hamradio stuff.
After looking for a stand for my FT-817 I found the page of OK1CSS Stepan Synekwho made a very simple wire stand for his FT-817. When you have a FT-817 and are looking for a simple, field compatible stand. This is the one.

A while I started to get interested in WSPR and QRSS communication. The fun part of that would be getting as much km / watt with a DIY of kit based baken transmitter.
When looking around for some schematics and kits, I found the website of Hans Summers who has designed the Ultimate3 QRSS kit (link : website ). This kit has the most of what you need onboard for WSPR and QRSS communication and all for a nice price (aprx euro 20,00 / $28,00).
Today I published my new QSL card design.

Of terwijl internet / ethernet via het stopcontact.
Eerst maar even een verkooppraatje
"Met een set powerline-adapters, ook wel homeplugs of ethernet over power (EoP) genoemd, leg je in no-time een computernetwerk aan via het bestaande elektriciteitsnet in huis. Een powerline-netwerk is een gemakkelijk alternatief voor een bedraad en draadloos netwerk. Een set van 2 adapters is eenvoudig uit te breiden met een losse adapter van hetzelfde merk."
Klinkt mooi he? Nou, er zit wel een klein addertje onder het gras. Of misschien zelfs wel een anaconda.

On 6 november 2013 I took the Full License exam and with just 7 errors on the 50 questions I have pasted it . Now it's just waiting for Agentschap Telecom to process it and confirm the result. What my new call will be ?? I don't know yet, but it will be something like my old call. .
Because most of the dutch repeaters now need CTCSS to operate, I couldn't use my old Kenwood TS-700G anymore for operations on those repeaters.
