Today I needed to use my K3/100 on AM. I found that the maximum power it would
deliver was about 5W. When the PA stage switches in it seems to make no
difference to the output.
All other modes give the correct output. I have run the TX gain cals OK.
I have the 13kHz FM filter in FL1 on TX which
The first thing I would do is load up the K3 Configuration Utility and

are both selected for FL1.

Hi Michael,

parallelling of the signal returns. However, how does twisted pair

The Navigator RS-232 cable plugs into the P3 RS232 connector marked PC
and the P3 (XCVR RS-232 connector) is connected to the K3 via another
RS-232 cable. The later cable is a male to female straight through type

thus may have rather different EMC behaviour. I was not disputing that
the far field component interacts at short distances. I was only saying

That could be either due to a fault or due to excessive heating of the

There is no direct way to mute the K3. The workaround is to place the K3
