English Version: https://youtu.be/N2Aigoczs0s Ma conclusion sur le QRPVer Minion SDR transceiver, une excellente radio malgré quelques défauts qui espérons seront résolus.
This is an off-center-fed dipole By Spiderbeam, the famous antenna mast manufacturer. It does work on the advertised bands, though your SWR will vary depending on location. I would prefer connectors instead of the wires straight into the potted BALUN... It is fairly light and the BALUN works. My results on Part 2 aren't really different than part 1 (link below). There will always be some residual common-mode RF current on the coax shield though, as with any OCFD antenna. The antenna radiator is made from UL-wire / Liv-2Yz (ultra light aramid synthetic fibre and copper strands, Insulated). The antenna comes including 12m coax which despite the low weight (only 185g) shows only very modest losses (~1dB on 40m, less than 2dB on 10m). Despite the lack of connectors which would make repairs very difficult, with careful handling, the occasional QRP tuner and maybe an extra RF choke, it looks like a decent choice for multi-band operations. Sorry about the jello in the video, problem with my phone...

I am not a fan of amplifiers, but it was hard to pass at $29 for 50 Watts. This amplifier kit from QRP Labs works only for CW and maybe FSK digital modes, NOT AM, DSB or SSB (Class C). It was designed for the QCX CW transceiver but would work with any radio capable of providing 5V on key-down. Operation is full-break-in (QSK). The kit is pretty easy to put together if you read the manual carefully. Mounting the final transistors requires some attention but the procedure is very well explained. I would describe it as easier than building the QCX itself. This amplifier is an incredible value. I can't wait for the QSX kit! In the meantime, this is a good project to help you wait...

Retrouvez moi demain matin Dimanche 25 Avril à 11:00 pour une session en direct, questions et réponses en Français. J'aurais aussi une radio branchée sur mon antenne loop magnétique. Faites passez le mot, avec mes excuses pour cette annonce quelque peu tardive...

Kit building is not as hard as one might think. Well, this one is... The Slop Bucket 2 by Steve Weber is a single-band SSB/CW transceiver that fits on a 4x4" board. I have high hopes for this kit but unfortunately it doesn't quite work; my mistake no doubt.

The Inverted-V antenna is great for NVIS (Near Vertical Incidence Skywave) regional radio contacts and will work also for long distances. Requiring only one mast it is very practical for portable operations. This part 1 is a FAIL because I got a very high SWR and poor reception. In part two I will figure it out, fix the antenna and make contacts. Get more content and help this site: https://www.patreon.com/radioprepper

After building a copper-tube J-Pole (and a Slim-Jim) for 2m, I decided to make one for 6m FM. I had made one using ladder line, but this one will be stand-alone and in two parts using a foldable military antenna. This way the antenna can fit in my truck to be used for portable operations. It can be scaled up for CB or up to 10m probably, though that would make it more of a base antenna than portable. I tested it with my Racal VRM-5080 at the beach..
