ATLAS Radio introduces....The NEW Model 310 HF Tranceiver for
SSB, CW, Packet and Amtor.
* Features DDS (Direct Digital Synthesis) Frequency Control.
* COVERS ALL 9 AMATEUR RADIO HF BANDS:
receives from 1.8 to 29.7 Mhz, and includes MARS and CAP frequencies. It will
also receive all the HF Marine frequencies, as well as short wave broadcasting.
(Note: As a transmitter, the 310 is designed only for amateur radio bands. It
is not type accepted for transmission in the marine frequencies.)
* POWER OUTPUT:
150 watts PEP in SSB mode, 120 watts on CW,
80 watts on Packet and AMTOR. No transmitter tuning is required. Power is panel
adjustable from 5 watts to full power. Rated power output requires 13.8 volts
DC at the rear power connector with full transmit power.
Lesser voltage will reduce power accordingly.
* DIGITIAL FREQUENCY DISPLAY:
7 digit readout to 10 Hz
increments. Digits are LCD (liquid crystal display) 0.4 in. high, are back
lighted for easy reading in light or dark surroundings.
* STANDARD FEATURES INCLUDE:
a) Break-in CW keying
b) Upper/lower sideband selection
c) PBT, Pass Band Tuning control
d) Internal speaker, top mounted
e) Noise blanker
f) The DDS has dual frequency capability which permits separate
transmit and receive frequencies anywhere in the band, as well as the
advantages of RIT.
* DDS, Direct Digital Synthesis, is a state-of-the-art system
for generating the injection frequency required by the receiver front end
mixer. The DDS chip is a product of Qualcomm, a San Diego, California company.
It provides an extremely clean and stable output to the mixer, in both receive
and transmit modes. The mixer is a Mini-Circuits component which assures high
standards of receiver performance. Typical Receiver Specs: .25 microvolt
sensitivity, Dynamic Range: 134 db, 3rd Order Intercept: 18 dBm. There is NO
PLL (Phase Lock Loop).
* SINGLE CONVERSION SUPERHETERODYNE.
The DDS LO output
converts the received signal to an Intermediate Frequency of 9 Mhz. A bank of 7
band pass filters provide more than 85 db image suppression. Each filter has 9
poles. Single conversion provides superior performance to multiple conversion,
and enhances the KISS principle.
* SWITCHABLE CRYSTAL FILTER:
Standard feature provides
choice of 3 band widths: 2.7 khz for normal SSB, 1.8 khz for narrow SSB in
crowded band conditions, and 0.6 khz for narrow band CW. 6 to 60 Shape Factor
is 1.4 to 1 in the 2.7 khz bandwidth position.
* DC POWER REQUIREMENTS: 12-14 volts at 500 Milliamps for
receive, up to 22 amps for transmit. Average with SSB modulation will be
approx. 8 amps.
* PHYSICAL SPECS.: 9 in wide, 3.5 in high, by 9 in deep.
Total weight, less power supply, 8 lbs.
* FACTORY DIRECT INTRODUCTORY PRICE: $795
Power supply Console for 110/220 volts AC, 50-60 Hz $189 (plugs
directly into the back)
Deluxe Mobile Mount (into which the Atlas 310 plugs) $ 69
