Amateur Radio Station
A friend of mine Gertjan PA3FZB who is crazy about 3.5m broadcast “amateur” stations 😉 recently came up with an article about a HB9CV design for 3.5m. He asked me if I could build it for him. and so it happened 🙂 On the internet there is a very handy calculation tool to calculate an…
First attempt to build a 23cm Yagi I had been looking for an antenna for 23 and 13cm for a while now. As I wanted to listen to SSB and Amateur Television stations. Now I had found some factory antennas online. Only the price.. hmmm.. For these prices I can build several antennas myself 🙂…
Some people asked my some questions about how to properly connect my Rotator interface to their rotators. Most common questions are: My rotator will not rotate back when rotation is at max position. I have got distorted readings on the display. How to properly connect the rotator interface to a rotator In this part…
Recently I got a call from my local dealer that I could finally pick up my long pre-ordered Icom IC-9700 🙂 The only antenna at the time I had for VHF/UHF was a Diamond X-30 Vertical. That’s nice for some local/regional work, but not really for some DX. Since I’m not going to place big…
Some time has passed, and a lot has been done so far. Construction Tuning Section First I had to find a way to mount the vacuum condenser on the mounting plate. Because I print a lot in 3D, I had the choice to design and print mounting brackets. Also important to include in the design…
TUNER SOLD IN 2023 As I have succesfully built the ATU-100 kit, I decided to go for a beafier ATU kit. Some weeks ago I received a kit from Ali Express. The ATU-1000 Automatic Antenna tuner kit. It is based on the same design of N7DCC, but the board is designed by EU2AV. The same…
My current antenna for 10 and 20m is still my old wire dipole. Construction is a wire Fan Dipole, in some slight inverterd V configuration directed East / West. Due the proper height of the antenna working DX is no problem at all.
Last week I have constructed a new antenna system for HF operations. 3 Years ago, I started with a 2 band FAN Dipole. for 10m and 20m. I have enjoyed operating with this antenna very very much. The only thing that was bothering me was that I could not operate on 40m. The lack of…
Yesterday I picked up a secondhand Wimo Bigwheel antenna for 2m. This antenna has somewhat more gain then my Homebrew SQualo. I have completely disassembled the antenna, and cleaned and rinsed all parts and elements. Also I had to create a new mounting bracket, as the original one was missing. Same as the SQualo antenna,…
13cm S-Band Helical antenna Since the antenna has to go on the satellite mast, and there is not much room for a dish, I decided to start off with a Helical antenna. I have build several in the past, and took the design from VE2ZAZ Back in 2005-2007 I had good experience with this helical…
