Using an Oscilloscope as a Station Monitor

After taking 9 minutes to show what takes 90 seconds, I won't be clicking on him any further.

Slick place to pick your signal off from. Never would've thought it.

I have a much simpler tap and I don't have to disconnect anything. I can use my Techtronics scope or any other scope. I simply make several turns of No.22 hookup wire and place it near my coax or better yet near a coax connector and the coil will pick up any leakage from the connector. Works every time and I don't have to build anything. I don't understand why everything has to be so complicated.

One thing you didnt tell your viewers, is NOT to EVER turn the tuner to the port you have connected to the oscilloscope (in your case ant 4) and transmit, or you'll send full power into the front end of the oscilloscope frying the front end immediately.

You missed showing the whole point of the video - the checking the gain and modulation with the oscope. All you did was show how you set it up but not the actual usage.

[@bryanwa7prc647]

There are MANY ways to "sniff" some signal. I just use a loop of wire (about 3' diameter) around my shack window. Then, I'm not tying-up a port on any radio equipment AND, there's no possibility of frying the frontend of my 'scope.

Thanks...I did a similar thing with an antenna switch/selector once to read a freq. counter. It was either too much juice or I had a drink (before I quit) and switched to the counter and blasted it directly. Glad it was an experimental $15 chinese job. Now, though: In the case of this boat anchor, it actually has a little sampling port where you can stick a wire (or better center conductor of coax) through a plastic tube into the air space inside the shield cage over the tube finals and it picks up nicely without overload . Now, though, I need to learn to calibrate the late model o-scope and identify 100% modulation. Seems people don't need a "demodulator" any more than they need an rf sampler, because they adjust the scope accordingly to ignore the carrier wave (compressing the time?)...but I guess I'm just one step away from knowing what 100% modulation of appropriate audio level looks like on the scope on AM...? I hope to conquer it before getting up from my chair... thanks!

really valuable. thank you

Thanks for the Video, My question is can I use a 50Mhz oscilloscope? And can i continually use it directly in line if i dont have a antenna tuner like yours with extra port... thanks! KM6EHD JOJO

[@cbradiomizfit7562]

What model scope is that?

[@awd3418]

your only getting 50 percent of the coupling , the signal doesn't even look right.

[@dalewdavis3034]

What connecter did you use from pl-259 to scope?

[@bryanwa7prc647]

He used a BNC-BNC cable. To interface to the tuner, he used a BNC-F to UHF-M adapter.
