K3/100 and SGC-500 incompatibility

[Jack Amsden]

I  own K3/100 SN 3161, and an SGC SG-500 Smartpowercube Linear Power Amplifier.

When the radio was a K3/10 it worked well with the Amplifier, giving a noticeable increase in power.

With the K3/100  (no internal antenna tuner) the Amplifier drops of line displaying a VSWR problem at any power level.  SGC advises this response normal when a 200 volt switching transient exists.

An Icom IC-7000 works well with the Amplifier/manual tuner/G5RV antenna.

Any help would be appreciated.

Thanks,

Jack, K7MKG
