Everyone knows it is important for the K3/100 to receive a solid DC supply.
If the supply drops significantly when high current is drawn several effects
may occur:
1 - The Transmitted signal becomes wider than it should be

Hi Joe
A device like the Mitsubishi RD100HHF1...
This device is used in most of the current Yaesu and Icom radios. It has very

Idg at 1 amp is very good at -50dbc. Even with IDg set at 0.5 amps the

The KPA100 will tolerate a 2:1 SWR with no problem. That is not
uncommon with solid state amps.
If you do have a HI SWR problem with the input circuit, it would likely
indicate a defective component in the input circuit (most likely a
capacitor).
