Of course weather conditions had an effect that made some adjustment necessary but it showed actual radiated signal as good as any remote receiver. Not a replacement for the proper monitor scope but a good compliment and with a diode det fed to a headphone amp could be used as an actual monitor as well.

You know... there are devices that produce a tone that rises or lowers 
in pitch, depending on how much power they're exposed to.

Useful aids for tuning amps for max, after SWR has been tuned for a 
minimum, for someone who can't see the meters.

for those of us who are non-visualy-handicapped, the external antenna, 
scope and a crystal detector would be a much -greater- aid to 
maintaining a clean AM signal, than relying solely on a pep reading 
watt-meter (which is limited by the how fast the movement of the meter 
is, in the first place)
