Just as a side note, I don't like using a big 35A power supply for testing relativly low current devices like a QRP rig or receiver. The reason is that any short in the circuit you are building can wipe out circuit board runs with 35A. If you don't have a smaller current limited supply available, at least put a 1 or 2A fast blow fuse in line on the output of the power supply.Well said Bob, this advice should be included in all QRP
. I build a LOT of QRP kits but use my
SEC 1223 because it's small enough to keep on the desk and
not get in the way. The bigger PS's are on the floor behind
the desk, I don't need the 1223's 23 Amps for QRP work, so my
QRP DC line includes a blade fuse holder.
I keep a 1 or 2A fuse in there at all times.
The blade fuses are quick and easy to change out too,
if you want more crrent for another project.
