[Hallicrafters] Need info on Halli prototype RF Analyzer

[Allan Fritsche]

Hi Phil and Group.
Phil, you always amaze me with the stuff you work on.
Where do you get these things?
It looks like a prototype built into a HA-1 TO keyer cabinent.
When you get any info, I bet Chuck Dachis would like to have it.
Hope the SX-88 came out all right.
Your old friend Al
