Just picked up a Hallicrafters TO keyer for the vintage desk also. Same keyer

*/Hi Curt,/*
I think that the one major difference betwixt the /EICO/& the /Hallicrafters TO/keyer is that very
same "...weak link" in the chain that affected mine here, i.e. the /TO/used (I believe) a sealed
mercury-wetted keying relay, whereas the /EICO/went with that reed-relay-in-a-field-coil route to
achieve its external keying...
I say weak link as no offence to the /EICO/designers, but rather, as a potential source for
trouble that may well require the owner's attention at some point in its future...trouble is, if
said owner is not all that familiar with the whys & wherefores of reed relays / field coils (my
right hand is raised!), then one can through a /LOT/of vexing gyrations & travails in the
trouble-shooting process that are simply not necessary...! *: >)*
