TWO STAGES IS SOMETIMES BETTER THAN ONE
The BB-1020 Broadband Preamp is two
stages of our BBP-.5-30
Preamp with selectable OFF, 10db or 20db gain. When 20db is
selected, the noise figure is in the 2.5db range, slightly better than
the BBP-.5-30. Sometimes just a little more gain or a little
better noise figure can make the difference. UHF (SO-239)
connectors are used and a plug-in power supply is included. MORE INFO |

DIGITAL
ACCURACY FOR YOUR VINTAGE STATION
The DD-103 Universal
Digital
Dial
provides digital accuracy for vintage receivers, transmitters, and
transceivers, by counting only the VFO (local oscillator). VFO and IF offset information for
many
receivers and transmitters (SEE LIST)
is pre-programmed
in the
display's
memory. This allows
the operating frequency to be displayed by counting
only the VFO. The
DD-103 uses a backlit
LCD. Installation is
usually possible without
soldering.
VFO
FREQUENCY MUST BE BELOW 40MHz. MORE
INFO: The DD-103 Is Designed For Receivers And Transceivers That Use Separate Crystals For Each Band, Or Are Double Or Triple Conversion |
