I would love to see a similar discussion (my apology if has already
happened and is in the archives) for hi-rel antenna relays in the
2 KW + range. Not that I plan QRO but I like to build in very high
reliability.

Just what relays are cost effective and reliable at the amp output
side of things.  Not necessarily thinking QSK, just something that
could be the antenna relay in the amp or an antenna selection relay.

For instance, what relays are used in the DX Engineering 5KW rated
antenna switch versus what relays are used in their 10KW rated
switch?  It would be an education for homebrewers to look up their specs
and see what it takes to get from the 5KW rated world to the 10KW
rated world.

Thanks  -- John  W0UN
