Hi Mike:

Tnx for the speedy reply.

I see nothing on the left side fo the display. At the moment the display has what looks to be 2 balnk spots fallowed
by 14.0  MHZ. I checked and the INHIB IN is set on DISABLE.

The wiring diagram is exactly as mine is which is a copy right out of the manual

Tnx Mike

Hi Mike,

When you transmit from the K3 what do you see on the left side of the KPA500
display. Obviously it's not an asterisk. Are you seeing an Underscore.

You may have accidentally programmed INHIB IN to ENABLE? See page 20 of the
KPA500 manual. You will want it to be in DISABLE.

/ENABLE allows the amplifier operation to be inhibited (won't amplify) when
a logic low is
applied to pin 11 of the AUX Connector (see pg 26). When amplification is
inhibited, an
underscore instead of the asterisk appears on the left end of the LCD
display./

73,
Mike K2MK
