31 - The SHELF-17

fantastic nick can not Waite for another project well done 73

Fantastic Nick! Great build and a really enjoyable narrative too.

Beautiful project 👍👍

Congratulations Nick, one of the best ‘TechArt’ designs I’ve seen, and clearly explained as you always do. As with many others, I’ve followed the build through from the beginning; thank you, 73’s Bob

wow nice. love watching your videos always a treat. keep up the good work

Great video fascinating stuff

Very Very well done. Nicely explained and well presented. Enjoyed taking the journey with you! Andy G0POY

I've followed the rig's progress all the way through and it's good to see the working result. 😀 Very well done and thanks for taking the time to make the videos... I know it adds a lot of time to projects. I learnt a lot through the series and a particularly useful part for me, this time, was the Arduino switching. I need something similar for a hombrew transmit and SDR receiver project. Take some time off, enjoy your new radio and I look forward to seeing any mods or your next project. Thanks again Nick.

The trick is to always build on a very 'pretty' piece of wood so people think it was 'intended' to be a breadboard rig. :)

A fine piece of al fresco work Nick and your explanation is incredibly thorough. The idea of doing the TR switching in Arduino code is not mine of course, but the sequencing it allows you to do  solves a lot of problems.  I normally have three control lines, Rx mute (obvious), TR relay (which pulls in the relay via a 2n7000 switch) and a PA enable, which applies PA bias.  The delays can be 10 to 20mS, and for the relay timing I usually consult the relay datasheet for pull-in and drop out times. The rig Rx sounds excellent as further proof of a working project. 73vPaul VK3HN.

Love every inch of it ! 73 PE1LLA

Great video and inspiring. Only discovered your channel quite recently. I've got back into the hobby and construction again after a twenty year break. Taken a slightly different path to you for now, modifying cheap Chinese stuff to do what I want them to do. Enjoy the way you enthuse over your work and explain things, well done. I have made a few videos of what I'm up to at the moment, but I am always changing direction as I travel along this path. Sadly though, I dont articulate as well as you do and my interest isn't really in video production. Oh..and I too have played with those chinese "70w" [non] linear amps, and have the pile of dead MOSFETs to prove it😂. Great stuff and will be binge viewing over Christmas. 73 G7EWL - YO2EWL
