meter pointer does not deflect off scale. The earphone ahows you to monitor
modulation.
WARNING: Tube type power amplifiers operate at high RF and DC potentials.
Transistorized power amps also produce high RF levels. Observe normal safety
procedures for high RF and DC circuits.

Use as a Field-Strength Meter

Your DM-81 can be used to measure the field strength of a transmit antenna. Set
up as directed in APPLICATIONS: "Use as Absorption frequency meter". In
addition, couple to an antenna as in Figure 9. You can now measure field strength.
This application is convenient for transmit antenna matching, radiation pattern
adjustments, and similar uses.
