[ARC5] AN/ARC-3

[Kenneth G. Gordon]

Wow! 

Mike, you're cool! :-)

I have essentially two each ARC-3 TX and RX, but nothing else. I understand 
the ARC-3 was used in a number of late WWII fighters. Is this true? Which? 
Someone once mentioned the P-38 and F6F....

What amazes me about them is their later models (ARC-36 and 49) with 
many more channels. Apparently it wasn't all that hard to add them.
