Thanks for this great video Ray. You clarified some of the operational questions I had on the VNA. I have one of these Nano VNA. We also have the tinySA spectrum analyzer which is also really neat. Its about the same size as the Nano VNA. Terry, WA0DTH
Great video. After watching, I set up my nanovna with one cable set with clip leads on just s11 to see if a tuned circuit resonance could be monitored using just this one port; it can. Set up your nanovna to read resistance and frequency sweep as in the video. When the tuned circuit is in resonance, its impedance will be extremely ( infinitely) high. Try setting scale division to say 2000 to get a better peak and have a marker track maximum. I found that the loop attena that I made with cat-5 cable has, at the moment, too much capacitance to tune to the upper part of the MW band
I've been thinking of getting one to look at my h/b tuneable band pass filters I'm going to use in my h/b tx/rx. As well as look at my various aerials. It looks like a useful gadget. Go on, bore me, I could do with a drink! Bill, G4GHB.
Hi Ray. I wanted to ask you what model number and brand nano vna you got there. I was looking at them on line on Amazon. There are so many different one's out there. Thanks again for sharing. Take care. 😊
@@g4nsj Hi Ray. I found one like yours under a different branded name. Same frequency layout. The name is Aursinc. The KKmoon was no longer available. I think they might both be made by the same manufacturer. Mine was 82.95 US with a 10 dollar coupon. Thanks again for the reply. Take care. 😊
I have an old philco 5 tube radio. I cant find the data for it. Is there a way to find out what the IF should be? Philco made their radios with many different IF's. Or does it even matter if I set the filters to match an IF?
I've checked and I can't find any data. Try guessing the frequency. You can always change it if it';s wrong. If I discover anything, I'll let you know.
@@g4nsj Thanks for the reply. I'll pick a common IF that has the least noise in my area and see if I can get the LO and Antenna to track together. I think I'll pickup a NanoVNA, I've been tuning with a VTVM and Signal injector this far.

Another great video, it’s difficult to explain magic and you always make me chuckle when you do, well done 👍🏼
Thanks Steve.
Really helpful, Ray. Many thanks for such clarity, as ever.
Thanks!
Very interesting as usual. Look forward to more.
Thanks!
Love the VNA content ray. Thanks!
Thanks!
Really interesting seeing some other uses for the NanoNVA other than just SWR measurements. I'm looking forward to the rest of the series. Cheers Ray
Thanks!
Just bought the NanoVNA, great bit of kit and your video's have helped me navigate it, Cheers Ray. 73 Adrian M0NOD
Glad it helped, Adrian. Cheers, Ray.
Cool explanation 😄
I love the NanoVNA
Hi Ray, enjoy your tea :-)
Thanks for the information about the nano vna.

Cheers!
Thanks, Ray!

That’s great, thanks for commenting. Cheers, Ray.
Nice...👍.

Bill, G4GHB.
Good idea, Bill.
you can make dip coils ray and use it in swr mode as dip meter.
Good idea!
Great video I just got one a bit ago n am have fun learn all I can do whith it
I'm still hopeing for you to have cups for sale 😁
73 stay safe
Cups for sale... love it! Cheers, Ray.

did you uuse coax to make your corodile clip test leads?
Yes, it's thin coax.

"L" because I was taken already ..?
L stands for inductor.
