This was the right speed and pace for teaching this complex subject. Your previous videos were too fast and assume your audience is already very familiar with SimSmith, Smith Charts, and RD design. More videos like this one please.
I just finished this and another dozen of your videos on SimSmith. I'm designing, simulating and plan to build prototypes of several ham bandpass filters. I need to know the maximum voltages across the caps and currents through the toroidal inductors for various transmitter power levels (100w, 400w and 1,500w) to determine the correct component sizing. This video clearly shows how to determine the required cao voltage rating(s) and toroidal inductor max currents that product Bmax. Thank you for this information.
Great video. You created the video at the correct pace. I have always found a thorough presentation regarding a topic as a great means to subsequently study the details. Seeing the forrest makes studying the trees much easier. Thanks!
Working my way from #1 video I thought this one might be a bit redundant, BUT turned out it was a good revision exercise, and I was impressed by how many SimSmith concepts you worked into it (including inv. and ifthenelse). One like this every now and again is a a good idea. I'd advise anybody new to SimSmith to view the Basics videos, maybe starting with #75.
JP, Glad that you have enjoyed the videos. SimSmith has evolved a lot from the early videos and re-doing some videos with the updated SimSmith features seemed like a wise choice. 73, Larry W0QE
A beautifully clear and helpful video (actually all of your videos are). Thank you VERY much you have given me a major jump-start to using this very powerful tool - very much appreciated sir. And since you asked for feedback, I thought the speed of presentation and the EZ-NEC (or VNA) import was extremely valuable. Aside from your amazing intuition and circuit analysis skill, I really appreciated that you showed exact syntax to achieve the variable definitions, how to establish parameters and link them, and creating plots and parameter sweeping, etc. You demonstrated how to use the extremely powerful interface of SimSmith - Astoundingly powerful. This particular video example explains exactly how to think through a practical loop antenna and matching network INCLUDING the essential issues of considering the the voltage and currents running around in the circuit - which are surprisingly high. There is a LOT here and you've done an excellent job explaining it. Thanks very, very much Larry!
I have watched several dozen of your videos now. All amazing work. Very patient and clear, from the easy to the mind stretching. This one is one of the best, IMO. I noticed you didn't use Zcen. When I tried to do that with my replicated .ssx (I copy typed along and compared), I noticed that it doesn't help much here. Having the centre relocated to some very (!) reactive location just gave an unreadable and highly distorted scale for me. It would have been good to have the .ssx and the EZNEC files posted on your website as you have done for many of the other videos.

Larry, your explanation was very informative and delivered at just the right speed, as far as I was concerned.

Larry, One of your best. I thought the speed of the demonstration was just right.
Thanks Tom,
Larry
What a powerful package!! Presentation and explanation was excellent. Thank you
Absolutely Awesome, It was easy to follow, I just pause the video go and try it on my SimSmith, Great Thanks Larry, Regards Neil.
Very nice job, Larry. Your pace was just right for me. You really use the tools well! Karl, AE0DL
Karl,
Thanks for the comment about the pace.

Oliver,
Send me an email to xxw0qe at gmail and I can send you the files if you wish.
Larry, W0QE
The speed was about right. It's a complex topic and it'll take a while to unravel, but I know what to look for. Thanks!
You are welcome.
Larry, W0QE
Larry, So good!!! happy to see your video...
Excellent presentation! Ken WA8FCI
Larry, well done!
Thanks!
Hello Larry, Excellent video, fine tutorial. 73, Jan PAØNON
Fascinating video! Is it possible to get a copy of the EZNEC antenna file?
Jay,
Send me you email and I will send you the EZNEC file.
Larry
Excellent, Thank you.
Tony,
Glad you found the video to be useful.
Larry, W0QE
Very educational. Thank you so much!! 73 de w8tam
