RX-340 has built-in TCVCXO to provide +/- 1 ppm frequency stability across the entire operating range of 0 to

50 degrees C. Audio is delivered to built-in speaker on the top panel, external speaker jack on rear and front

panel headphone jack. Separate volume controls provided for speaker and headphone. Fixed level 600 ohm

audio is also provided on rear panel. Front panel is a Lexan graphics overlay designed to last a lifetime. Chassis

is aluminum with alodine plating on all parts to protect finish in less than ideal environments. Measuring

5.25"x19"x12.5"(HWD), RX-340 can be mounted in a standard 19" opening rack and weighs 12.5 lbs. One year

warranty. Made in U.S.A.

RX-340 was recently endorsed by noted receiver design engineer, Dr. Ulrich L. Rohde, KA2WEU:

"In testing the RX-340, I find that this is the only affordable, totally DSP-based receiver where the digital AGC

is as good, if not better than analog AGC systems. The intercept point for reasonable spacing is very impressive,

better than +35 dBm in all cases."

What about DRM (Digital Radio Mondiale) decoding? RX-340 is ready to use for DRM - all you need is the

decoding software available from DRM. Instructions for using the RX-340 to decode DRM can be read by

WorldStation, a sophisticated software package to operate the RX-340 under computer control, is now available

from DXTra, Inc. Click here to access the DXTra website at www.dxtra.com - DXTra, Inc. is a Ten-Tec

authorized value-added reseller of Ten-Tec receiver products.

RX-340 SPECIFICATIONS

FREQUENCY COVERAGE: 50kHz - 30 MHz at typical sensitivity. Tunable down to 0 MHz with degraded

performance (see Sensitivity tables) MODE: USB, LSB, ISB, CW, AM, Synchronous AM, FM; all standard.

TUNING RESOLUTION: 1 Hz steps.

FREQUENCY STABILITY: using built-in TCVCXO, provides +/-1 PPM over entire operating range 0 - 50

degrees C.

ACCURACY: All internal oscillators are locked to either internal or external frequency standard.

EXTERNAL FREQUENCY REFERENCE: 1, 2, 5, or 10 MHz ( +/- 1 PPM, 200 mv p-p into high impedance

load). Receiver automatically switches to this reference upon application, at power up or after any serial link

activity.

SPURIOUS RESPONSES: All spurious less than -119 dBm equivalent input - preamp on.

IMAGE REJECTION: 90 dB typical, 80 dB minimum

BFO: Tunable in CW mode only, +/- 8 kHz. Tuning in 10 Hz steps. Fixed frequency in SSB/ISB, disabled in

AM and FM.

SYNTHESIZER LOCK TIME: 10 msec typical

ANTENNA INPUT : 50 ohm, unbalanced, BNC connector. 2.5:1 VSWR max @ receiver's tuned frequency.

SELECTIVITY : 57 bandwidths selectable from .1 kHz - 16.0 kHz. Shape factor 1.5:1 or better. (6 to 60 dB)

Bandwidth is fixed at 3.2 kHz in ISB mode, and at 4 kHz - 16 kHz in SAM mode. Minimum bandwidth is 600

Hz in FM mode.

GROUP DELAY : no more than .1 ms variation over passband of 300 Hz to 3050 Hz.

ULTIMATE REJECTION: 70 dB minimum regardless of filter selected. L.O.

PHASE NOISE: -120 dBc/Hz @ 20 kHz offset typical, -110 dBc/Hz maximum.
