Hey guys,
After a recent lightning event I find that my 20M 3-high stack
controller got zapped. This is an IC based homebrew design that a friend
made for me in the 90's.
I'll be able to swap in the 10M controller as a temporary fix, but going
forward am wondering if there is an easy commercial replacement
available, maybe with a bit more flexibility (more relay outputs).
I currently need to be able to control 7 relays in 7 programmable
different combinations (all involving either 1, 5, or 6 of the relays to
be energized at a time, per the K3LR article from the 90's).
My current control boxes have 7 buttons each of which can direct access
the 7 relay combos. I much prefer this over any rotary control switch.
Anyway, I know this is a simple task for a little Arduino box and relay
controller - is there anything out there that is (almost) ready to go?
Thanks,
-Steve K8LX
