[Milsurplus] TCS-12 - TX

Sun, 8 Jun 2003 13:04:12 +0200

Can any-one help me with info on the Collins TCS 12 Transmitter?
Just the circuit (schematic) would be a huge step forward!

Subject: [Milsurplus] SCR-508 conversion info

HI all

We've all seen the ham radio magazine articles on how to convert various
pieces of gear to ham use, but I just came across a "professional"
conversion
article.

The NAB Engineering Handbook, circa 1960 or so, has a chapter devoted to
the conversion of the SCR-508 set to a one way remote pickup link for
broadcast
use. Actually a pretty minimal conversion, mainly involved in rewiring the
filaments
for 6 volt and using a PE-103 for a power supply.  Article suggests
repainting the
cabinets for a more pleasing appearance.

Article then goes on to say a BC-375 (or 191) can be used on a "talkback"
channel of 1606 kc (this was legal back in '60), after conversion to
crystal control.

Just thought someone would find this interesting.

Jack

As we are not on the beaches this year I shall be in the shack looking =

for contacts, 80, 40 and 20. =

Will have several sets operational, WS68, WS22, WS19 and if conditions =

are poor will resort to slightly more modern stuff (20 year old) with ssb=
,
though I know its =

frowned upon by some !!.

3575/3625,  7025/7045,  14055/14205

So, look forward to working a few, maybe the omaha group if they are
operational from the bunker this year. =

Subject: Re: [Milsurplus] German electronics innovations, WW2

Hello All,

>I was thinking today of these features i have noticed about German WW2
>radio electronics, and wondering if in fact these were the first
appearances
>of such innovations:
>5) Tape antenna ( built with multiple layers of tape-measure like metal.
>( Feldfunk series radio, also maybe KlFud ).  Seen in USA PRC-8, 9, 10

I have noticed that the Russians adopted many of the German innovations
except the tape antenna.  They used the Kulikov antenna that is made up of
metal spools held together with a steel cable.  I would have thought that
the relative ease of producing the tape antenna would have made it a clear
choice.
Does anyone know the history of the development of the Kulikov antenna?
