Ok I now have audio.....I can hear "hiss" fairly loudly as well as strong sidetone when I go into the stl menu.  I replaced C11 and audio sprung to life.

I proceeded to wind L1 and installed it, then re-installed my filter board and now I get the E42, "No VFO."  I can go into the menus and successfully have the K1 see the two bands that the filter board support and can switch between them, no problems but I can't proceed further due to the E42.  

The audio I hear is strong but is of course just "hiss" since the VFO isn't working yet (therefore I don't hear anything other than the hiss and hence the E42).

I was told that sometimes D17 installed backwards could cause this.  I checked its orientation and it is correct.  I also checked soldering around some of the other caps that some have said can be an issue and reflowed them just to be safe.  

I am continuing to try tracing out the issue but any ideas on where else I might look, on the offchance anyone else has encountered this same thing?
