[GreenKeys] Current loop not providing (enough) current

[Zach Zarzycki]

So there was a little operator error here, therefore, Jordan, I really don't think the board is bad. I didn't swap my lead on the meter from v to ma (amperage , ma are separate ports, then volts, ohms, temp, diodes and caps on another port).

I have 60mA at the supply, between the 2 points it hooks to the PC interface and therefore at the terminal hookups on the teletype. between two windings down the loop on unit itself it reads 53mA, and at 2 other windings 0. 

The break key and any strike does break the loop. Now it's a matter of figuring out why the machine itself / magnet won't energize. 


I'm going though the schematic again to see if coils are supposed to be  in parallel or series with the way I have the loop hooked in - thinking about what Ralph had said with regard to reversed coils.

Ralph,  Ohio, and yeah, 40 is 2 far and my hf setup right now is awful, antenna down and what not!
