[ARC5] R-508/ARC Conversion

[n2lxm at juno.com]

Greeting All,

        Thanks Tim. I now found that the Dynamotor That was on the
receiver is the wrong one. It's Dynamotor unit " Type D-10A(28V), also
marked DY-89/ARN-30. Seems the DC in and High Voltage out are not
comparable with the R-19 / R-508/ARC. Not a big deal. I have plenty of
transformers that I can build up a supply with the needed Filament and
High voltages. Going to clip lead up your schematic and use my bench
supplies to see if the old girl comes to life.

It's true..They work just fine "stock"...

I got several requests about the system TX/TX/Control interconnects in
the system I built.  So yesterday I added a sketch down at the bottom of
my article to show that.  No cutting required!

Robert:  The Manual shows which wires were installed at the factory when
changing the filament supply voltage design between 12/24V primary. 
Similar process as in an ARC-5 receiver.


Have fun!

Step #1 in the Conversion:  

Set the choke on your chainsaw..........insure that you have adequate
fuel available.

Ugh..

Greetings All,


        Has anyone converted an R-508/ARC using the article in the June
1965 issue of 73 Magazine ?. I would like to get this old girl running so
I can listen in on out local airport Automated weather transmissions.
