Bravo! It would be cool to see a cutaway view of the innards for the mere mortals. We now pause for station identification while the engineers bow and praise the Nautel xmiter. 73
UA-cam suggested your channel today. (New Sub here) Many years ago I used to work with optical circulators. They were probably the most expensive part in our test equipment, with exception to some laser diodes. We used them in our high end 50dB OTDR's, so we could avoid the 50% loss of a coupler. RF on the other hand is what one UA-camr refers to as the 'Darkest of the Dark Arts' I look forward to more.
I would like to ask you a question coming from a layman who likes to watch UA-cam videos. If I inject an audio tone of a specific frequency and level into a transmitter to obtain the appropriate null in the carrier to equate to 100% but then add a second tone like a 9% pilot or an RDS stream does it add to the total deviation and if so can you insert them all and re-null the first to establish your max dev? I'm guessing like a little b***h here but still curious about the workings and formulas at play.. Thanks.
Fascinating! I know enough about RF to be dangerous (and to get my ham ticket, LOL) but I didn't know how circulators worked, or some of the reasons for them. Thanks!
RF isolators are absolute dark magic. if you open one, it will be empty. if you close it, it will work perfectly, attenuating RF in only one direction. HOW??? WHY??? why are they sometimes magnetic and sometimes just literally an EMPTY SHELL

Great video, I'm excited to see more!
I knew about circulators being used for repeaters, but wasn't expecting them to show up here
I've been a Broadcast Engineer for many years and have never known this. Looking forward to more videos from your channel!

A picture of the innards would be good; the first time I opened one up it freaked me out how it could do anything useful with so little in it.

😮cool vid
can you open it and show us the inside?

It's Pikachu.
