[ICOM] IC-215 alignment inst. ???

[Dave Edwards]

I am not surprised...The GLB board was a club project back in the day. I am 
the only one that got it going all the way to using it...on my Clegg!!!  By 
the time I finished high school, then college, then started to work for 
HP....where I could get my hands on a spectrum analyzer...the GLB was a 
distant memory!!!
...Dave
