Trivia (a little off) pertaining to the care
and feeding of relay contacts in ICOM gear:
At AT&T we placed a small current on cable
pairs that were used for carrier transmission.
Any poor connections, (high resistance), were
made to look like a forward biased diode.
"Sealing Current" not used on Plain Old
Telephone pairs because they already had DC
current on them. Bye
