[Elecraft] RF build up

[N2TK, Tony]

That's what my Acom amp is for. Don't usually need it. The K2/100 by itself
typically keeps the frost RF off the antennas. I relabeled the ON switch to
RF Heater on my amp. Had to use it last night. Temp dropped to 4 degrees and
had snow. It was sluggish trying to get my CW speed up.  After the RF Heater
warmed up CW was flowing fine.
Happy Holidays.
N2TK, Tony

now this is why you want an air dielectric on your coax that way you can
hook a heat gun and blow hot air up to the frozen rf and thaw it out.
you could also try cognac after a few you won't care about the frozen rf

another thing is to get a couple dozen young hams together give them each a
mirror 2"X2" than have them reflect the suns light on the antenna with
enough mirrors you will be able to warm that frozen rf right out off the
antenna and make it as good as new.( of course to much heat will destroy
it.)
