[Lowfer] First try with the Spec Lab 96kHz SDR....

[Michael Sapp]

Seasons Greetings All:   Got the bug to try the SDR in Spec Lab, wound up a 
25/75 turn 9:1 isolation transformer on a T75 toriod (highest u core I have 
on hand)  and ran my short e-probe 20ft from the house into the sound 
card...too much wide noise at 19kHz, but several MSKs copied so it was worth 
the effort.....

Obviously needs work tho.....

I'll listen on my modified HD-1420 this morning with the EWE on 17.2 and see 
what happens. The 19kHz noise is barely detectable on the EWE so there may 
be hope.  Even if I can capture something on QRSS it would be encouraging...

73, Mike wa3tts
