[Elecraft] KSB2 and SSBA settings?

[Leigh L Klotz, Jr.]

I have a KSB2 and MH2 that I just completed as well.  I got a report of 
"low audio" from my one SSB contact so far, F5PFP in Lyons, France, and 
the vox seems hard to trigger.  I was running my K5OOR amp on 17m, so 
somewhere between 25 and 40W expected output, though I don't have a PEP 
meter (yet) so I don't know for real.

I am unsure of how to make sense of a report of "low audio" on SSB--how 
is that different from "low power?"  I had the mic gain set at 3 and the 
compresion at 3:1.

I noticed the current draw was 0.24-0.26A before and 0.40 after, so I 
removed the KSB2 board and checked and cleaned it, but no change.  Then 
I slide some paper between the RFCs and the filter XTALs and the draw 
went down to 0.28, all according to the internal meter.  I removed the 
paper and still about the same.  So I dunno.

The vox is not very sensitive, and almost impossible to trigger with the 
10dB attenuator (SSBa 1) in place, and difficult with SSBa 3, though I 
haven't tried Vox again since my paper trick.

I will try it again...I almost called Art Bell on 75M on Saturday night 
to ask for a mic check but he then said he was going QRT to do his 
show...
