[Johnson] Wanted:Info on Adventurer Modulator

[Tony Martin]

Joe,
In response to your request for help with the Adventurer and the Viking
Adventurer Modulator (250-40), I went
up in the attic and dug through a box of things that have been in a
state of "storage" for 40+ years and found the modulator, complete with
the full set of instructions for assembling and hooking it up to the
Adventurer.

I will try to get copies made this week and send the complete info to
you (15 pages).  I still have my Adventurer from 1955...it has been with
me all over the world and served as my "driver/exciter" for a 4-400
Class C amplifier I used as EL2AD back in 1963-65..great fun and
wonderful memories.  Also used it at 7Q7AA and PY1ZBA.  

I never hooked up the modulator, in fact after looking at it, it appears
to be about 75% assembled.  Sorry for rambling....if you are OK in
QRZ.COM, I will get the info off to you this week.

73 and good luck.

Tony, W4FOA
