In this video, we progress from the Parasitic array and use the techniques in Phase Angles and Velocity Factor to build a switchable array left/right. This can also be driven without the phasing loop to crate a N/S pattern but personally I don’t think it’s worth it – and the tuning goes to pot too. OK if you are desperate I guess! Callum.

Hilarious that I didn’t have a ROGER, YES or QSL in my bank to press 🙂

I was about to call RU1A when someone else jumped in with MY CALL!? I jumped in and saved the day 🙂

Every time I mention Man-Made QRM, I get an argument from someone telling me I have it wrong. Well, I’ve only been doing this 20 years so I need to know. What is it? QRM or QRN?

Recorded earlier this year – it was a LONG stream. This is an edited version.
Original stream was here: https://youtube.com/live/_ZYVtz1bxGg

Some folks think I screwed the board to the desk.. This time, I wasn’t as stupid as I normally am and it didn’t go the way you thought! 🙂

This second cabinet is for the Genius 8×2 remote switch, CCTV, Ethernet Switch, Mains and WiFi etc, etc . This one is from RS Online. It’s 50mm / 2-inches deeper than the previous one which is just as well because EcoFlex 15 doesn’t bend very well! I didn’t know it was this deep when I ordered it but handy anyway. Callum.

I have JUST plugged this in and so far it exceeds my expectation. Works with any radio although deep inside the guts, Flex is supported heavily as well as Yaesu and Icom. But any radio will work with this. You just need an ethernet connection between your shack and this box (and a 12V supply) to your shack bulkhead. In my case, it’s going out in the field in a professional electrical metal box. I will show you that video at a later date – this is my initial findings. Enjoy! Callum.
