[ARC5] Re: Modulators

[zeno]

I remember one reason hams in the 50s used the ARC 5 type 
transmitters which they could pick up for $10 at the local ham 
surplus shack on Beverly Blvd. (man what a place that was!!!!), they 
could build a simple modulator and be on AM, very economically. What 
was that modulator circuit? Must have been in the old handbooks. 
Anyone here built a good home-brew modulator for an "ARC-5" xmtr? 
Guess I will see these things when I get some of the old books and 
manuals I have been trying to track down. I am getting ahead of 
myself since I do not even have one of these units up and running 
even on CW, but I was curious about this.
Anyone having fun building a modulator from scratch? What approach 
would one use these days? Recycling old tube gear and parts from the 
junkbox? Or is there something else. How common are the original 
military modulators for these?
