button. Signals will be shown on the bar graph on opposite sides of the starting frequency. A cursor will appear
and allow you to tune RX-350 to any signal visible on the screen. Easy!
The 1024 memories (in 8 banks of 128 channels each) retain frequency, mode and bandwidth information.
Memories are grouped into several banks for easy storage of frequencies from different bands. An alphanumeric
tag function of up to 8 letters allows memories to be tagged with specific names like "WSEV 930" or "VOA",
etc.
Scan functions allow scanning of band segments or memory banks. Memory bank scan feature includes a
memory lockout function for skipping of constantly busy channels. Band scanning is user-programmable; set the
start and stop frequencies, push a button and the radio starts to scan between the two frequencies.
Built in clock displayed on LCD screen displays hours, minutes, and seconds in user-selectable 12 or 24 hour
format. Timer circuitry and a squelch-activated output allow for monitoring and/or taping of band activity even
when the user is not present. Timer function allows the radio to be set in a 'wait' mode, to power on at a specific
time and to send a control signal for actuation of accessory equipment. Two separate timer outputs are provided
for connection of two separate devices to be actuated by the timer circuit. The squelch-activated output allows
the radio to be left on and squelched on a given frequency. When a signal is present to open the squelch, an
actuation signal is sent via a rear-panel jack.
Rear panel Hi-Z and Lo-Z antenna inputs allow connection of virtually any antenna to the RX-350. Built-in AC
switching power supply allows operation of RX-350 from either 115 or 230 VAC. Separate DC power input
jack can be used for 13.8 VDC operation. AC and DC supply can be connected at the same time for back-up.
Plug the RX-350 into the wall and connect to battery supply. If the AC power goes off, the connected DC source
automatically takes over power to the receiver. Mute function for muting of receiver if used with a companion
transmitter. 12.125x5x13 inches.
An optional remote encoder knob/keypad, model 302, is available for armchair operation of the RX-350. Simply
plug the 302 into the rear panel of the RX-350 via the provided 6 foot cable. The 302 provides a duplicate of the
main tuning knob of the receiver, a direct frequency entry keypad, and three functions buttons that can be
user-assigned to control various receiver functions like mode switching, main tuning knob step size, SWEEP
actuation, etc. Main tuning knob on the receiver front panel and all other receiver functions are active even when
the 302 is in use. Sit back and relax!
No other shortwave receiver packs this much value 'under the hood'. To top it off, it's MADE IN USA and
competitively priced! Put the RX-350 side-by-side with your present HF receiver and see for yourself why
