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

[Adam Farson]

Hi Dave,

Have you ever seen the output of a GLB Channelizer on a spectrum analyzer?
Oh my! Talk about porcupines!

Cheers for now, 73,
Adam VA7OJ/AB4OJ

By the way...I built a GLB 'channelizer myself. But I was in late high
school...so it was around '75 Still have an unstuffed GLB board sitting
where I left it...on my dad's workbench. Only put the IC socket pins in,
then a IC-230 or 22S or something arrived!!!  That ended that!
...Dave
