The latest piece of news

New updates will folow soon! - by PG1N 28/04/2024 @ 22:22

I will update the links soon, as some have changed or no longer exist. New links will also be added.
The most important change will be that the links to images will disappear. On the one hand because site owners have indicated that they do not appreciate this, and on the other hand because being fit saves me a lot of time and effort.

Welcome to PG1N's HAM Radio Site

Besides information about myself and my premier hobby, HAM Radio, in general, you can find here many hambrew links. During my queest for nice projects, I found so many nice ones, which I want to join with other HAMs.

I wish everyone lots of fun at my site!

73, Maarten PG1N

Introducing myself

QSL PG1NMy name is Maarten Ouwehand, I am 58 years young and radio amateur, wich you could guess already, hi.
I am a member of the VERON Centrum.
An other big hobby of mine is scouting.

My equipment

Kenwood TS-940SKenwood TS-940S

My favorite piece ofequipment is ofcourse my Kenwood TS-940S. Since also C-licenced amateurs are allowed to use HF ite is used many times. At the moment it is been repaired, so I have to use my XYLs Yeasu FT101ZD.

Links TS-940S:

  • RigPix - Kenwood TS-940S
  • Mods.Dk - Kenwood TS-940S

    My homebrew projects

    One of my latest projects is the RockMite, a 20 meter QRP CW transceiver. The Trx shown at the picture was just finnished during the 2005 fieldday but rejected to function properly. After some test it seemed that one of the resistors was incorrect. Because of the little time I have it is still at my workbench. At the picture you also can see the keyer I have made of a nailpolisher.

    Rock Mite bijna afgebouwd
