Thank you. Best, Don

Very cool indeed. I would love to see a longer version of this video... but definitely don't let me decide what you do with your free time! 😆

[@RestoreOldRadios]

Thanks for reaching out William. I’ll keep this in mind for a future video if time allows. Best, Don

I simply use my old E200C Precision signal generator and run the audio into the modulation inputs, then I can transmit on any frequency the signal gen produces. I do verify that the transmitted signal is 100MW or less to comply with FCC rules and regs.

Ditto for me at times too using my old Lodestar RF Generator. Thanks for watching and reaching out. Best, Don

Hi Don. I watched this last night, I forgot to comment. Cool circuit my friend. As always I liked and shared. All my very best to you and yours.

[@RestoreOldRadios]

I always appreciate you watching and sharing Bobby. All the best. Don

Great circuit Don, Thank you!

[@RestoreOldRadios]

I appreciate it Gregg. It's been too cold to do any chassis work (painting) after rust removal, so I thought I would give this circuit a try. Best, Don

0hhh awesome use of this opamp Don! I know I have these too in my lab stock! I just noticed a twin-tee notch filter in your design! Very cool for selecting those freq too! Sweet, thanks for sharing 👍

[@RestoreOldRadios]

Appreciate it Tony. I had a couple of them laying around and the simplistic Twin-t design was one I had never tried. Hope this finds you doing well. Best, Don

[@saturn5tony]

@@RestoreOldRadios I may not known about this as well (maybe back in 77 when I got my degree) but just found it on w2aew's youtube #380: Circuit Fun: Twin-Tee Oscillator. So cool to see this as a constant osc as well. Fun stuff Don :)

Huh?
