My OZ2CPU digitale RF mW-dBm-mV meter has a  input range from 1nW to 1W which is good enough for QRPp rigs and my TinySA has a imput limit of +10dBm / 10mW.  When you want to measure on equipment which gives more output power, you need a serious set of attenuators, or you could build yourself a 40dB RF sampler.

After a few weeks I decided to setup the dish temporary in my backyard and made some cables to wire every thing up.. The original setup had a off focus placed 4.5 turn helix which was ok, but didn't give the expected  punch and  the signals where a little bit weak in SSB on the QO-100. Other operators told me that the signal was readable but not that strong.  So that was one thing to improve and the idea a of a new Helix feed was born.

A few months ago I ordered a  ATU100 kit from China (without a case), and on a rainy weekend I decided to build it together.  This ATU is equipped with a 1.3" OLEDd display and one thing I hate about these displays is that you almost can't install them without damaging the glass. Thinking about it, I decided that I need a 3D printable frame which puts all the mechanic stress on the PCB instead on the glass  . . .  Continue reading . . .

Years ago my childeren build a few crystal radio kit from Chris Dorna PE1DZX which he sold through his website. When Chhris stopped making these kits, he let that website expire to be lost for ever. Recently I was contacted by a ham who wanted to build these radio's and still had the kit building instructions in PDF. I asked Chris if he was ok with it that I shared these PDF's and hosted them on my website. Chris was ok with that so from now on the kit building instructions can be downloaded here.

When I got my hands on a used NanoVNA H4 I couldn't resist looking inside to see if it was using shielding for the RF components. Turned out it did so I bought the right one. But one thing I noticed was the component silkscreen for a micro SD-card slot without the slot it self and because it still contained the original software which didn't mention anything about saving images to SD cards, I didn't do anything with it.

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.

Beeing a longtime listener of the SolderSmoke podcast. I have heart many things about the BitX20 radio developed by Ashhar Farhan, VU2ESE. A lot of hams build that rig in variouse ways, but have build and owning a ILER20, a second diy 20m rig wasn't on my list. 

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.

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.

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).

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.

Hamradio operators need to log there QSO's and many do that the modern way with log programme's. But sometimes paper just works more relaxed. So I made a collection of different logsheets in landscape design (3 qso, 5 qso, 26 qso, 26 contest) you can download for printing. The documents can be found in the HamRadio Download section of the homepage. (link)

Na een dag on-inspirerend totaal niet creatief werk op de zaak (offertes doornemen), moest het er even allemaal uit. Het resultaat is een Handhebeldraisine geworden zonder motortje, bedoeld als scenery voor op mijn toekomstige module baan.
