5-4. Model VX-5 VOX
The Model VX-5 is the VOX accessory that is installed in the lower section of the Model 220-CS Console.
Controls for VOX Gain, Anti-VOX, and Delay are brought out to the console front panel. AC consoles may be
ordered with VOX installed, or can be easily owner or dealer installed.
5-5. Model DD-6B Digital Dial
with built-in Frequency Counter Capability
In addition to being a digital dial, the DD-6B will also function as a sensitive frequency counter from 100 Hz to 40
MHz, for general use around the ham shack or lab. Input terminals and selector switch for this function are located
on the rear panel.
• DIGITAL HOLD provides frequency memory which holds the digital display. This allows you to tune to other
frequencies while retaining the frequency reading you expect to return to.
• Another new feature now provides for correct reading on opposite sideband, as well as the normally used
sideband.
• All L.E.D. Dot Matrix 6 digit display reads within 100 Hz (just 1/10 kHz) of your actual operating frequency.
• Bright display clearly visible under high ambient light.
• Reads on both Receive and Transmit.
• Measures 1 3/8 high x 5 3/8 wide x 5 7/8 deep.
ATTENTION SWAN OWNERS
In addition to operating with all Atlas transceivers, the DD-6B can be made to operate with
Swan models 350C, 500C, 500CX, 700CX, 270, 270B, 300B, 600R, and 600T.
ATTENTION DRAKE R4 AND EARLIER MODEL SWAN OWNERS
The DD-6C model is the same in all respects as the DD-6B, except that it is modified to operate
with the Drake R4 series as well as the earlier Swan models 350, 400, and 500.
Instructions furnished with both models of the Digital Dial give complete information on the
minor modifications required for use with Swan and Drake units. DD6-B or DD-6C
