[Amps] Transmit signal monitoring AM & SSB

[Gary Schafer]

To look at the modulated signal you need to do is place the scope probe tip
near the antenna coax and it will usually pick up enough signal. If not
attach a few inches of wire to the probe tip.
Your Hitachi scope will give you a better picture than any of the old
monitor scopes.
