[Elecraft] ERR TXG ON CALIBARTION

[km5ps]

Where can I look for more information on a ERR TXG error.  I turned on 
the K3 today and was not getting any power out, did a tx calibration in 
K3 Utility  and got this error  ERR TXG.  I am sure there has been 
postings before, but I don't know the link to search for them.
Any help would be great.  Also would a factory reset fix the problem?  
Running MCU  4.51.



TIA
John
