I am analyzing a system that can be modeled as a 2nd class fulcrum. The link below about 1/3 of the way down the page shows an example of a 2nd class fulcrum.
2nd class fulcrum Link
The part that makes up the beam is a composite part made up of a turnbuckle (see link below), threaded tube...
Sorry I dont have any pics, but i'll do my best to describe this.
I have a 1" deep 3/4-16 threaded hole drilled down the center axis of a the end of a 1.25" square steel rod. A bolt goes thru the center of a high strength rod end (heim joint) and the bolt threads into the 3/4-16 hole the full...
I am building a non-regenerative repeater for several waveforms, one of which is AM voice. I'd like to reduce the IF filter bandwidth from 25 KHz to 10 KHz or less to reduce amplified noise power and ACI.
I've seen filters as narrow as 6 KHz used for AM voice HAM radios. Since voice tends...
I need to electrically isolate the heat sink for a LM317. I don't want the heat sink to have the voltage on it (potential short hazard for my application).
I believe that I can get a thermally conductive electrically isolating tape or pad for between the tab on the LM317 and the heat sink...
I am working with a supplier to have them build a repeater for a comm system. The repeater has to repeat AM signals (not SSB), a BPSK signal, and a BPSK signal that has been spread by a spreading code.
The supplier asked me if they were to use the image out of a mixer that was the inverse...
