Default Input power limiting on VHF (2m) linear amplifier

Hey OT:

Fuses are nice, I can tell you from experience, they are slow slow
slow when it comes time to blow, even so called fast blow fuses are
slow.
The real reason to have a fuse is to prevent a fire.

hey

Calculating for 50 mW at 50 Ohms, yields about 32 mA. *DigiKey (in the
USA) sells 50 mA fuses in surface mount packages, which would be ideal
for putting across a cut in a circuit trace inside the amp. *A 50 mA
fuse should blow at about 125 mW.
