Tektronix model 1L5 spectrum analyzer plug in for sale, with manual.
10Hz-1 Mhz range.
 
Fun for looking at modem signals, hooking to your stereo, pipe-organ 
work, etc. 
 
Add a mixer and scan the shortwave bands for numbers stations.
 
Be aware it is analog though. You will need a high-persistence phosphor,
chart recorder, or A/D converter for the low frequency stuff. If you 
are interested in signal above a few Khz any 500 series scope should be fine.
 
$250.00. Maybe nogotiable.
 
I may be interested in selling the 545B it lives in, too.
