[Milsurplus] Wobulator

[Bruce Gentry]

It does indeed have a surplus wobulator- from an APN-1 radar altimeter, 
not the APS-13 '"tail end charlie".  The APS-13 used pulse modulation, 
not FM.  The item offered is  a homebrew sweep and marker generator for 
practising a 99.9% extinct art- aligning the tuner and IF in analog 
television receivers.  I remember seeing the article and instructions to 
build it in an ancient Radio & TV technical magazine.
