Reg, I dug up some calculations from sci.physics.electromag
from about a year ago that indicate one foot of 50 ohm coax
on each side of the Bird is enough to make the line real,
i.e. not imaginary, and that's a conservative estimate.
===========================================

Cec, I still have a 30-watt, 160m, portable transceiver which I made
about 20 years back. It's in an aluminium attache case and still
works. In my travelling days I used to toss a wire out of the hotel
bedroom window.

Lift the lid and on the front panel is a 1.5"-square moving-coil
meter. It is used as a TLI on transmit and as an S-meter on receive.

The meter scale is calibrated 0-500 microamps.

But my imagination doesn't fool ME.

On receive, when the meter indicates 50% of full-scale deflection I
know that the meter is actually measuring 250 microamps.

And on transmit, when the meter indicates 90% of full scale deflection
I know that the meter is actually measuring 450 microamps.

Let this little anecdote be a friendly warning to they who use meters
with a 0 to infinity SWR scale, or scaled in terms of forward and
reverse power.
