re Coice of ATU
It won't be long before the ultimate fully automatic ATU is built into
transceivers.
We've had AGC ever since the vari-mu screen-grid valve was invented 75 years
back. This abolished the RF gain control but no doubt there is still a
residue of moaners and groaners.
The present so-called SWR meter (a stupid instrument if ever there was one)
can then be abolished from front panels and, indeed, exiled from radio
shacks for evermore and a day. Good riddance!
To provide something to talk about, write on SWL cards and enter in log
books, only the S-meter need be retained. This can be re-named "Received
Signal Strength Meter" and calibrated in more meaningful terms such as
decibels relative to 1 micro-watt.
It's obvious from its name, a signal strength meter always has been a power
meter. Pre-21st Century Old Wives kindly note. ;o)
