Amateur Radio Station
Update! 30-12-2022 It’s been a while since I gave an update on the Magnetic Loop controller project I’m working on with Rob PA5RH. The purpose of the Loop Tuner was that it can tune automatically, and uses the internal SWR meter of the connected radio, and reads this via CAT. Connection will eventually be possible…
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…
Recently my colleague, Rob PA5RH and I came up with the idea to build an automatic loop tuner. Rob is busy with the software part where I have already started on the mechanical part. As loop, Cellflex 1 1/4 inch Coax cable is used. This has a (copper) outer diameter of +/- 38mm I want…
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…
Recently I purchased a ATU-100 Antenna tuner kit from Aliexpress. I have purchased this kit because the internal tuner of my IC-7610 has a tuning limit of 150ohms / SWR <3:1 as most internal tuners do. My previous IC-7300 had the tuner modification which extended the tuning limit, so tuning my antenna was no proplem…
How to get the CC41-A to work with your applications. I have bought several of these fake HM-10 modules, called CC41-A Left one is the original HM-10 module, in the middle is the fake CC41-A one. Anyways, besides it is a fake one, the major problem i bumped into, was the fact It would not…
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…
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…
Building the SQualo antenna for 2m For some time now I am very active on FT8 on HF. I enjoyed it so much because the high QRM level I have on HF. Then some fellow amateurs at the club, asked me if I was active on 2 meters too?. I got home, hooked up my…
