DIGITAL ACCURACY FOR YOUR VINTAGE STATION
The DD-103 Is Designed For Receivers And Transceivers That Use Separate
Crystals For Each Band, Or Are Double Or Triple Conversion

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:

TWO STAGES IS SOMETIMES BETTER THAN ONE
The BB-1020 Broadband Preamp is two stages of our BBPV 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 BBPV.  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
