(7) RF Stray and Odd Shut Down
It may happen that a part of the amplified large RF signal intrudes into the radio system
to cause such an instable behavior during the transmission, that the transmission signal
gets distorted, and that DC power supply voltage jumps up.
To cure these troubles, it is suggested that clip-on ferrite cores are inserted at both
ends of all the DC power and control cables as well as coax cables.
Such ferrite cores are available from Amidon Associates, Palomar Engineers, TDK
Corp. and so on.
When “PROT” LED lights, you need to reset the amplifier to release the shut-down.
After checking possible causes of shut-down, turn off and on the POWER switch to
reset.
