[ARC5] More Fun with BC-230 - 30 Meters

[David Stinson]

While working on a way to get the BC-230 5-6 MC coil to
scoot-up to 40 meters, I managed to booger-ize one of
the PA Tank/Antenna coils.
Rather than can it, I rewound it.  Used the BC-230 with
the 6AQ5s  (have abandoned the 5763s- too hard to
neutralize and de-FM).  Unwound the tinned coil wire,
 covered the thin, fragile link coil under it with a single layer
of tape and used the tinned wire to wind a 12-turn tank coil.
Yes; the wire's "lumpy" from being on that form.
I'll rewind it with fresh wire later.
Here's a crummy picture:

Fiddled-around with the output tap until I found
the "sweet spot."   Now it doubles in the output
and gives me a couple of watts out on 30 meters.
Here's the keying using the original dynamotor supply
and the original relays, which you can hear also.
 A set keyed with a "modern" DPDT relay will key
much faster and quieter:

I'm really getting to like these little rigs.
My ARC-5s are jealous and pouting.
