Really easy. Process COMPLETELY non-invasive.
Pull VT52s & Key B+ to the BC-230(430) with a relay
Key up, p-s sinks to 5000 ohms, key down the '230 gets the juice...
mechanical regulation,
Ratchet out all L in C301 / 80m plug. Put variable C in series w.
output link terminal to cancel link's Xl. Use qrp tuner
to run it up to 10w in.
As GI appliance, never did "icw." TX intended for mcw & never ran "icw"
in P26s, P36s, etc. But it seems not to care.
There's another "converting the BC230" art'l in a '58 CQ. Reminded
me of the recipe for carp where you nail fish to board & bake
@ 500F for some time. Then remove, discard carp remains, & eat board.
