About 75-100 volts, 20 mA or so. Positive to ground.

I just did the math, Jim. You're sinking more power in your keying
circuit than a lot QRPers deliver to the antenna!

Not really, Hans.

The 75-100 volts is open-circuit, measured with a VTVM. The 20 mA is
short-circuit.

Of course the pilot lights on the Type 7 (6.3 V at about .8 amp total) use more
power than many QRPers deliver to the antenna....
