Last night I worked 46 EU from 0300z till about 0600.
In spite of the elevated solar wind, the band was in great shape into VE6.

Just a few mins past SS here. LB6GG is on and that's it so far.

Not sure what conditions are like, but I hope we'll get a few stations on

Not relevant to my topband setup, but For the high-impedance (ladder line) side
of my switching, I use open-frame relays with the contacts pried a little
further apart than stock. Example part is the McMaster Carr 7384K14. N6RK
outlines the process
Continuing from N4ZR’s relay thread and Rob’s observation:
For low impedance (50 ohm ballpark) side switching, I went to Struthers Dunn
(now P&B) DPDT T92 relays with paralleled 30A contacts. I got a big boy
legal-limit amp and have been COMPLETELY happy with these at legal limit.

Yes Rob, my TX vertical feedpoint was closer to 7 ohm before it being
transformed to 50 ohm by means of a auto transformer style bottom coil and tap.
I have used a big fat relay with massive silver contacts, (it was used in a UPS
to switch battery banks) but with the actuator coil wires fed tro
Actually, if you have a quarter wave driven element and you are
disconnecting it at the feedpoint, your relay concern shouldn't be
voltage so much as current. Fast switching and large contact surface
is more important than voltage handling.
