Thanks to everyone for the many replies. It seems that a lot of
people like Astrons!
Someone speculated that ones with meters could let out RFI.
That's true if the meters are plastic...it's just another hole
for RF to get in/out -- but the case of these supplies may have
plastic parts and/or not be totally sealed for RF anyway, so
meters may not matter much. Unless they use bare metal and
fingerstock gasketing where parts join, it's not RF tight.
It would be interesting to hear people with the Astron switchers
test for noise by connecting them to the K2 and then connecting
a short wire to the antenna jack and tuning around. Receive is
more important than transmit, with one rig, and the ARRL report
only showed transmit. (The SS-30 had hash in 160 but the other
bands were clean(er).)
I don't plan to run anything else simultaneously so the 25A continuous
from the SS-30 would be plenty. If I go the RS-35 route, hopefully I
can locate it far enough away from the rig because of the magnetic
fields.
