KENWOOD DM-81
3
FEATURES
1. Measurable frequency range is 700kHz to 25OMHz in seven bands.
2. All seven dip meter coils, capacitive probe, earphone and ground clip lead, can be
carried within the unit for easy transport and storage.
3. Convenient for both in indoor and outdoor measurements, all solid-state and built-
in battery.
4. HC-25U and FT-243 sockets enable use as a crystal checker and marker
generator.
5. Amplitude modulation is convenient in aligning receivers when using your DM-
81 as a signal generator. Also, when used as the marker generator, amplitude
modulation is helpful in precisely calibrating the dial scale even for a receiver
having no BFO.
6. An FET and transistor are used in the meter circuit to provide extremely good
sensitivity.
7. As an absorption frequency meter, your DM-81 is used both to align transmitters
and measure field strength.
8. An earphone plug allows you to monitor transmitted signals.
9. A capacitive probe allows measurements without removing coil shields.
10. It is possible to measure resonant circuit frequencies of toroidal coils. This is not
possible with conventional dip meters.
