Wooo Hooo! Perfect timing! I recently took a stroll down the 'ol oscilloscope garden path, followed Alice down a rabbit hole and popped out in Oz. All your videos are great for the pros & begginers alike. I can't think of anything more quantitatively & qualitatively entertaining on a Friday night. Many thanks for sharing Alan!

[@BradleyMabe]

You are a great teacher. Entertaining and informative. In the dictionary under Elmer, it says see you!

[@tocsa120ls]

Nice presentation, thanks Alan.

[@FairlawnARC]

This is W2NZ. Thank you for your feedback. If you look closely Alan is wearing a lavalier, the recorder is hung off the rear of his belt; that file was lost, found, rebuilt and was unusable. There were four additional audio recordings, one from each of the 3 cameras used in this multi-cam production plus one generated by our webmaster's laptop. Each of these recordings had problems based upon their location, 2 of which have high-quality shotgun mics. The video here, unfortunately, was *over-processed*; kzbin.info/www/bejne/qKPJYZZ-adSSnZY

Dang, 'bout fell out of the chair with that ending "scream"! TNX Alan, great info. 73 - Dino KL0S

[@zvpunry1971]

Thanks for the warning! But even with the expectation of some scary scream I jumped a bit. ;)

[@w2aew]

Surprised me too! A little “gift” from the club’s video producer.

Hi Alan I was wondering where Part 2 was after watching Part 1. This will give me a few things to try with my scope. It's a good way to understand the basic relationships and math, better than just using an LCR meter as you say. Thanks once again.

[@DonDegidio]

Hi Alan, Excellent visuals with the oscilloscope. Enjoyed this video as well as part 1. 73 WB3BJU

[@timka880057]

I couldn't hear some of the words, it cut in and out. But I love the info on the circuits for testing, love your videos Thanks.

[@nlimchua]

would've been better if they provide you with a lavalier mic so the audio doesn't sound 'hollow'. But thanks for posting, nevertheless. All your videos are time well spent! 73! - KD2CBI

[@ProdigalPorcupine]

Nelson Chua - I assumed Alan actually had a lavalier wireless mic for the recording, and the handheld mic was for the PA. It sounded phasey, like a lav mic picking up both Alan’s voice and the PA speaker, and the delay causing cancellations etc.. Alan’s presentation as always was flawless, but with the greatest of respect to those doing the video, the miking up needs working on. The small venue probably doesn’t help with the sound reflections!

[@jagadu100]

What bandwidth would I need in a ‘scope to align a SSB generator?

[@w2aew]

You'd have to be more specific regarding the alignment procedure and the test signals involved.

[@robertcalkjr.8325]

Thanks Alan. Another great lesson! I guess that surprise near the end was there in case anyone fell asleep??

[@w2aew]

Yeah, that’s a good reason! It was put in there by the radio club’s videographer.

[@robertcalkjr.8325]

lol

[@electronic7979]

Nice

Hi Allen, Great content! (as usual!). The audio in this video, though, (I know ... not something that was very controllable by yourself), was really lacking in intelligibility. And for an old timer like myself, I need all the intelligibility I can get. The bit of extra bass and reverberation (as well as a bit of room echo) all contributed to the degradation of intelligibility of what you were saying. And I really wanted to hear and understand everything you were saying. So for the benefit of future recorders of Allen's videos, Add a mixer to your audio chain, and record the audio from the mixer, rather than the speakers, and the room. (I believe Allen was using a Shure SM-58, which is an excellent microphone, but it's purity was destroyed by the room acoustics, and the tone control on the amp [Bass emphasis may be great for music, but it doesn't promote intelligible audio in a lecturing or speaking mode]). I really appreciated all of the practical applications that you showed us. It would be really great if you could add links that would show how to build all the cool interfaces that you used. Thank you for sharing your knowledge and ability with us on KZbin! :)

[@neilsheldon8355]

My apologies for misspelling your name.

[@neilsheldon8355]

One more comment ... if you could add your slide show to the mix of links, that would be super! ... !thank you!

[@neilsheldon8355]

If you already did, my bad for missing it.

[@neilsheldon8355]

(BTW ... my personal favorite mixer is the Mackie 1402VLZ series. I have like 3 or 4 of them that I use in my own home. They add an incredible amount of interfacing ability to nearly any audio project, while maintaining proper impedance levels and fidelity. I am not associated in any way, shape or form with Mackie, but I use them in my own audio projects because they are a very cost effective way of delivering clean audio at the impedances and levels that you need for a great many audio projects. You can get cheaper stuff, but ... Hey! "I'm just sayin!" ... you get what you pay for.. For us older folks everything that you can do to improve audio counts! The more natural it sounds to us, the better)

[@neilsheldon8355]

Sorry, Alan ... Off my soap box now ...

[@joopterwijn]

Really lick these presentations, but Alan.... the sound.... 😭

[@w2aew]

Sorry, not my recording so I have little control over that.

[@DeeegerD]

Sorry inaudible for the most part - too difficult to listen to. I'm sure the information is the usual top quality. Unfortunate.

[@w2aew]

Sorry, out of my control, I didn’t do the recording.
