[GreenKeys] ST6 tuning scope circuit needed

[Gary Chatters]

Perhaps he just wants to build his own.  But I would take your 
approach.  Almost any audio oscilloscope with X and Y inputs could do 
the job.  I have acquired a couple of nice HP-1200B rack mount scopes.  
They are two channel scopes with triggered sweep and about 500kHz 
bandwidth.  More capability than you need for this application but it 
works nicely.  At one time I had an HP-1208B  X-Y display.  It was 
similar to the HP-1200B, but only had X and Y amplifiers, no sweep.

Whether you decide to build or buy, I do recommend using a scope for 
tuning.  It is much easier than with a meter.

73,
Gary
