[ARC5] When without a BC456, what do you use as a keying relay?

[Mark K3MSB]

I can’t recall the relay ratings;  I’ll try to remember to check this
weekend (which is filled with winterization projects before the cold wx
sets in…..)

Thinking about it, it is not the typical P&B octal base relay that I
initially posted; it’s one with spade lugs but they’re not uncommon.   I
have a drawer full of various voltage relays (6, 12, 24 DC,  110 AC etc)
and they’re readily available at festers, so I’m usually not concerned
about zorching a relay if the contact ratings aren’t up to snuff.

A comment for you.  From previous posts I get the impression that you’re
trying to build the “ultimate” setup at first shot.   Getting ARC-5’s on
the air was for me, and I suspect a lot of others, a learning and
experimentation process that never ends.   My setup, including power
supplies, have gone through various stages.    I found that the simple
voltage divider schema that’s in the manuals and exposited by Preacher Dave
is the best way to go!  It’s simple… and it works!     I tried the route of
choke input power supplies with Zener regulated voltages etc, but the
divider is what I settled on.   Is it the “best”?  Probably not;  Can it be
improved upon?  Probably.  But… it works!
