Amateur Radio Station
Some time ago, Hans PE1ICE developed a compact ATV Receiver that could demodulate FM audio and Nicam audio also. Link to project: https://nvra.net/index.php/nicam-decoder/pe1ice-nvra-mini-atv-ontvanger/ All that was needed was to install the receiver in a housing. In the first housing I had based on a supply voltage of 12v. I also had a video splitter built…
Reception at 10Ghz can be quite a challenge, especially if you can receive the station to be received on the edge. I really had the problem that the signal went up and down even with a little bit of wind. The problem was that the mast on which the dish is placed is in a…
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 🙂…
Simple conversion description MX62M with BNC Connectors UPDATE! 02-07-2023 I have replaced the BNC Pigtail cable with a fixed BNC Panelmount version instead to be more flexible. Recently I was looking for an easy way to build a Diplexer for my Icom IC-705. My eye fell on the Diamond MX62M Diplexer. This because with…
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…
