[GreenKeys] Heathkit (was Flesher Corp TU-170 Plus)

[Duncan Brown]

Heath also made the HD-3006 "Crossfire" tuning indicator (Two crossed 
rows of LEDs like what Dovetron used to replace the CRT in their later 
units). It could replace a scope as an add-on tuning indicator for a 
ST-6, etc.

There was also the HD-3030, "RTTY Terminal Interface", but I don't know 
just what it did.
