Im clearing out of the ham den my old Wavetek 3001 rf signal generator  – so maybe 15-18 yrs back or so , I think this was off freq or something and I tried to get it working better but it went from poor to no work – it is unlocked and not working  and been sitting in the bottom corner for yrs and yrs and yrs — good solid heavy-duty unit when it works and a great parts unit if you have one of these already .  I pulled it out took pictures of what is unlocking and then put the covers on.

$40 obo  parts unit
