[Heathkit] Re; HO-10 scope hash

[manualman@juno.com]

The HO-10's usefulness is on the transmitter side monitoring your
transmit signal. On the receiver side, it's usefulness diminishes down to
being "cute" to watch all the signals, noise, etc. bounce around the
screen. Very few, if any, real accurate readings, measurements, etc. can
be taken when connected to the output of the receiver's last IF stage.
However, a panadapter, "scanalyzer" or equivalent, connected to the first
mixer stage ahead of any IF amplification, provides a more accurate
representation of a receive signal including it's bandwidth and also
allows you to monitor a band segment for signals without constantly
tuning. This is great for VHF work, 75 meters in the middle of the
afternoon, or 10 meters during the summer.
