[Elecraft] External 10 Mhz reference level

[Dave Sublette]

Ed, et.al.,

I did get my instructions out for the EXTREF.  I had forgotten that there
were extra  sheets for that.  I use an HP Z3801 through an 8 way splitter
and run the 10 MHz from the garage to the shack, a fifty foot run, on .14
in diameter 75 ohm cable.  I also put a 1:1 isolation transformer in that
line before it left the garage.

By the time it got to the shack, there was only -1.0 dBm left.  So I took
my DEMI 4 output box and tried that.  It wouldn't put out more than +2 dBm
to the K3s.  So, I hacked the circuit board, taking one of the four
circuits and using it as a driver for the other three.  I now get 12.5 dBm
drive to the K3s.  All the asterisks are lit.  All appears to be working as
advertised.

Thanks for all the advice.  It helps to know I am not alone in making these
sorts of decisions.

73,

Dave, K4TO
