[Heathkit] Amp Keying Interface?

[Bob McGraw - K4TAX]

Be advised that Harbach Electronics is closed due to health reasons and not 
accepting orders at this time.

A simple keying interface is a 12VDC coil relay with N.O. contacts available 
from Radio Shack.  Enclose same in a small "project box" with a couple of 
connectors of your choice.  The 12V is from the FT-847 and the normal keying 
ckt and the N.O. contacts go to the SB-200.  The project should cost about 
$6.00 for all the parts and then have the fun of building something that 
works.
