[Elecraft] K3 kit #1244 ERR TXG

[Tony Morgan]

Trying to do the transmitter gain alignment (5 watt)
Getting the ERR TXG on all bands.
KPA3 not installed.
Stock 2.7 filter installed only.
All modes set to use this filter on xmit using K3 utility.
Have run synth alignment  & ref osc alignment several times.
All tmp cables are in correct locations with good connections.
Latest firmware 2.46 installed.
Looked through archives but no help so far.
Any ideas appreciated.
