Every year I try and listen to the BBC Antarctic Midwinter Broadcast. It’s become a bit of a tradition to sit back with a whisky on the rocks and enjoy this unique program that is broadcast by the BBC World Service. The broadcast was made on 3 frequencies; 7305 kHz from Ascension, 9505 kHz from …
We’ve recently moved to the new BT FTTP service and enjoy a nice, stable 500Mbps download speed. We’re equipped with a Ubiquity UniFi system in the house which uses a USG (Ubiquity Security Gateway) as out main firewall/router. We connect the Openreach ONT (the white box that Openreach install where the fibre terminates and provides …
I’ve decided to move my store from this website over to it’s own dedicated site. The ecommerce software is much better and very fast. I’ve always sold my products under the “LMK Technical Services” brand which is my sole trading name and moving them to a dedicated site makes this much more transparent. The new …
I’m designing a simple weatherproof case for the VHF Design range of QRO LNA devices. More details to come but here’s a taster. This was a rough, fast test print to check for fit. The design is available on thangs.com (https://thangs.com/mythangs/file/30489) for free so anyone with access to a 3D printer can make one. I …
I’ve had a 3D printer for some time now and I’ve been experimenting with various settings, filaments and prints. I’ve got to a point where I’m happy with the results and am pleased to announce a new product line of 3D printed items for the Amateur Radio and Shortwave Listener hobby. The first of my …
In 2019 I organised a trip to a remote farm in Devon for a mini DX-pedition, a sort of radio holiday for a few good friends and club members to play radio non stop for 5 days with 10 acres of field to erect antennas and a non existent HF noise floor. We took three …
The PWRpath is an interesting and handy device that allows a load (in this case, my station equipment) to be powered from a mains PSU while simultaneously charging a backup battery. In the event of a mains power failure, the load will automatically switch over to battery power with no interruption of the power supply. …
I’m a big fan of PowerPole connectors and have been watching the Chunzehui F-1005 on Amazon for some time. It was a bit more that I was willing to spend at it’s regular £59 price point but it want direct to my basket when it recently went on special offer for £29.50. It’s well made …
Don’t want to build your own? I now sell these and an alternative design with a better, fixed external unit on my shop! The Icom IC-9700 has a GPS data input available but no oficial accessory from Icom. It’s a 2.5mm TRS connection that allows users to connect a GPS unit with an RS232 output …
You’ve probably seen the MLA-30 Active Loop Antenna on Ebay. It can be had for a bargain price of around £35 and works great for the price. There’s only one problem in my book; the PCB is covered in epoxy potting and you can’t see the design or repair/modify it! Something that I’ll have to …
