[Elecraft] K3 - No power / SWR metering

[Nick-WA5BDU]

Is this an operator error, or what?

This evening I don't get any SWR or watts metering on my K3, just CMP 
and ALC, like I was on SSB.  I'm fairly sure that earlier in the evening 
I did have the expected SWR and power indications.  When I transmit, I 
get 6 bars of "ALC" and no bars of SWR, regardless of power level.  S 
meter works, CWT on/off works. 

Here's what I tried -

Cycled through all modes.  Recalled memories.  A/B switch (I don't have 
the sub receiver).  Power off and back on.  Re-loaded firmware (2.80).

Is there a configuration item I might have wrong?

Thanks,

Nick, WA5BDU
