[ARC5] 1ST QSO with my BC-454-B and T-19

[Mark K3MSB]

Hi Mike --

Take a look at the PS.  It's composed of the commercial 28V 15A supply atop
the main chassis, and the big HB chassis for B+, screen, and OSC voltages.

On the very right of the HB chassis are 3 jacks,  ANT, TX and RX;  the ANT
is the top jack which feeds the 200pf  capacitor.  The jacks go to an
internal 28V DPST relay.   The relay is activated by the toggle switch on
the front panel.

The DPST relay controls the 200V OSC voltage as well as antenna switching.
I wasn't too sure how this was going to work (RF so close to the OSC), but
it seems to work OK.

I have a T-22 and a BC-455-B sitting on the shelf which I plan on starting
in January.

Ultimately, I plan to house the antenna switching relay in a separate box
with a switch for 80/40 meters that will select the 2 series capacitors,
and also house the 4:1 UNUN.
