Glad to see you back, Bob!

Thanks. It's just been a busy month and I took some much needed R&R.

[@MrDoneboy]

@@Vocademy-Electronics-Tech I can dig that!

@@Vocademy-Electronics-Tech R&R, what's that. In my world that's remove and replace. LOL, I do that all day with bad parts.

Sadly one of the nicest people you could ever meet who was a legend in the microphone industry passed away earlier this year. Bob Heil silent key K9EID. His granddaughter got his callsign as a vanity call. All Hail the Heil microphone. 73

The D104 roshet salt crystal condenser microphone is still a extremely popular microphone. The later D104 ceramic microphone was also a mass produced cartridge but lacked the "smoothness" of the original crystal cartridge.

You truly are an incredible instructor. You thoroughly explain concepts, address the nuance, and even anticipate questions and answer them. Just outstanding..

With the information in this video we can build our own telephone system without using transistors or vacuum tubes

Forgot the crystal or ceramic mike. That uses a piezoelectric element to generate voltage from sound pressure waves. Much cheaper to assemble than dynamic mikes. Frequency response may be wise but contain peaks and dips.
