Title: Skycrafters VHF Multiphone
Post by: NQ5V on February 12, 2021, 11:11:33 AM
In the 70's I picked up a VHF transceiver (where I can't remember) with the thought of converting it to some ham use.  It was about a 10" cube of raw aluminum consisting of two boxes held together by lunch pail latches, with a 1/4 wave vertical in a pl259 on top and switches, mic and phones jack and volume control on the side.  The bottom box was full of assorted dry batteries. With 1 and 3 volt filament tubes, plate and screen modulated AM (low power), and a carbon mic,  this was a single channel unit on the 122 mc aircraft band.

It is long gone, and I don't know when or where, but I still have the schematic that was folded into the battery box.  I attach it for your amusement.

Ooh!  Thanks for posting this.  I have one of these, somewhere, got it years ago.  They used a bunch of surplus ARC-5 or ARC Type 12 parts on these.  When I was a kid I thought these were the neatest thing ever, that maybe you could hear Sky King on one.  Never found the slightest documentation until now!
