HF Receivers

High performance HF Receivers at a reasonable cost are becoming more and more difficult to source.

Here we offer a range of receivers.

Ten Tec RX340 Professional

HF Communications Receiver

The RX-340 is a truly affordable professional grade receiver. The entire specifications are too lengthy to reproduce here. Following are some of the more significant details

 

Some of the Major Features

 

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 and FM. The highest tuning resolution is in 1 Hz steps.

 

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.

 

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

 

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.

 

AUDIO LINE OUTPUT: 0 dBm (+/- 3 dBm) Two 600 ohm outputs (one for each sideband in ISB mode ) to DB-15 connector, ungrounded center tap. In all other modes, signal is mono. Terminals may be grounded or shorted together without damage. Two additional mono outputs are provided, one AC coupled, one DC coupled.

 

HEADPHONE OUTPUT: 1/4" stereo phone jack. Stereo in ISB mode, switchable to LSB, USB or both. Mono in all other modes. 10 mw maximum into 600 ohms. Front panel volume control.

 

DIGITAL DATA OUTPUT: Provides post DSP IF and audio information in both serial and parallel data streams.

 

REMOTE CONTROL: All receiver functions can be exercised using a multidrop RS232 serial port.

 

Can be mounted in a 3U space in a 19 inch rack.

 

       

Ten Tec RX-320D PC Controlled HF Receiver

The TEN-TEC RX-320D PC-controlled shortwave receiver allows quality SWLing for a fraction of the price of other shortwave receivers. Load the 1 MB of software from a single floppy disk to your hard drive, connect the RX-320D to an open serial port, plug the radio into the wall and you're ready to explore the world.

 

Fitted with an IF output suitable to connect a PC sound card for DRM reception.

TTS Systems

Good things can come in small packages. This little receiver is an outstanding performer with most of the features you would expect to see on the larger units.
