[Elecraft] Display error

[Larry Godek]

In chasing my audio at the Line out jacks problem i noticed that when i turn on the Sub rx i get a "GF" error and then the frequency display shows the dialed frequency.  It's just there momentarily.  This has been happening for some time but i forgot about it.

Today for some reason i noticed that i had lost and signals i had tuned in on the Sub rx.  Worked fine yesterday.  Now i see noise coming from the Sub rx, i hear it in my headphones but there is no signal of any sort there.  The Main rx sounds fine but nothing out of the Sub but random noise.  I have been watching the Line out audio thru the PC using DM780 or MMTTY or WSPR or any of several different display programs.  

Yesterday and early this morning i was watching the WSPR frequencies on the Sub rx and tuning the CW band (20 meters) with the Main rx.  Then later in the morning i noticed that i was no longer processing any signals thru the Sub rx.  Only one antenna hooked to the radio.  Where did i go wrong?  or, what went wrong?    I'm wondering if the "GF" is what might be part of my problem here.  Anyone see that before?  

Lets start with this.
