Amateur Radio Station
Last week I have received a nice package from India 🙂 I have purchased a uBitx Transceiver from http://www.hfsignals.com It is a pre-built basic direct conversion radio designed by Ashhar Farhan VU2ESE. The thing that pulled me over to buy the kit is the possibility to connect a Nextion touchscreen display to it. I have quite some…
To be able to calibrate the Analyzer properly (OSL), we need accurate loads. It is also important that the loads over the entire spectrum also function well, show no reflections or have other characteristics than a good load. This is quite easy to make yourself.
I have always wanted A good analyzer for HF up to VHF (2m) In the past I have build many Antenna Analyzers started with: Antan Analyzer VK5JST Antenna Analyzer Toghether with Jarek SP2SWJ we have built the BIGVNA MAX5 & MAX3 Big VNA Max 5 Max 3 Some weeks ago while I was surfing the…
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…
This morning ( 6th of may 2018 ) there was some brief propagation on 70cms. I have managed to work OZ1JMN with FT8 on my Diamond X-300 Vertical with just 20W. Few minutes later a QSO with DO1EJK . I think I will build and add a 70cm bigwheel to the mast in a couple…
Today I have managed to get my Weblogbook scripting working with Log4Om, The logbook has to be ofcourse MySQL. It is now possible to simply choose between a HRD or Log4om logbook. Also some changes where made on the looks of the program 🙂 Check it out at the project pages! Weblog Scripting project
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,…
Last week between the 9th and 17th of April, I visited my favorite Island of the Canary Islands, Gran Canaria. One of the things I wanted to do, is visiting the “Magic mountain” Contest station EA8AH. The station is used for many contests with different callsigns. Unfortunally there where no activities that weekend, but I…
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…
Rotator Interface I have created this page with all information needed to build your own Rotator Interface. On this page you will find the minimal requirements and hardware configuration needed to embed this in your own Rotator interface / situation. The initial design of this Rotator Interface is based on AC Rotator motors, and Analog…
