[Boatanchors] SB-200 info needed

[Bob Peters]

I have not seen an ICOM radio yet that can take the keying on an older
amp... I always use an AMP keyer even on my Alpha... Not ready to take any
chances
On burning out those mini relays and it does happen guys...The MFJ or
Ameritron Amp Keyers are cheap compared to ICOM service Good insurance...

Yes. We're only talking a few tens of milliamperes here.
