Ah! Traditional amateur radio, what did you use as a receiver?

vu2nan-nandu · 4th Jan 2015, 2:31 pm

Hi OM Tyso,

The receiver was RCA BC-312D.

Many thanks.

Very neat, very traditional, and very good to see.

Hello OM Nandu(?),

Was this built recently, or am I correct in assuming that you are sharing it with us many years after it was built?

And I am intrigued to know what "OM" means, please.

Nick.

Nick,
OM means "Old Man".
A friendly term used by radio hams between each other.

Cheers

Hi OM Nick,
It's as old as the hills (1977 and still going strong)!

Hi OM Howard,
Thanks.

Many moons ago (over 50 years) I am afraid I flew "The Jolly Roger"! Circuit out of PW 6V6 modulator I built but can't remember the rest.

Hi OM Dave,

I guess we all did!

Those were the days!
