RX-320D PC Radio - only $329.00 factory direct Mute: for use in transmit/receive applications, mutes audio

and IF outputs. (revised 3/6/00)

FREQUENCY RANGE: 100 kHz - 30 MHz

The introduction of the original Ten-Tec RX-320 HF DSP "PC Radio" in 1998 marked the first time that the

power of a personal computer could be harnessed and dedicated to superb quality shortwave listening. Instead of

traditional discrete electronic components inside the radio, the RX-320 utilized digital signal processors inside

the 'black box' and used your personal computer for the horsepower to run the radio. Replacing components with

software code resulted in less cost to manufacture the radio, and vastly better receiver performance than could be

afforded at the same price with a traditional component-based shortwave radio.

In 2003, Ten-Tec remains on the cutting edge of receiver technology by offering "plug and play" capability for

the new Digital Radio Mondiale (DRM) digital broadcasting standard in the new model RX-320D.

Q. What's the difference between the original world famous Ten-Tec RX-320 and the RX-320D model?

A. Only the addition of a 12 kHz I-F output jack that allows received signals to be streamed from the I-F directly

to your computer's sound card for Digital Radio Mondiale decoding.

Q. What is Digital Radio Mondiale (DRM)?

A. Digital Radio Mondiale is a consortium of radio and electronics manufacturers from around the world that

banded together in the late 1990's to create a universal digital system for the AM broadcasting bands below 30

MHz -- shortwave, mediumwave and longwave. The system that was created also bears the name of the group;

Digital Radio Mondiale. DRM is the world's only non-proprietary, digital system for shortwave, mediumwave

and longwave with the ability to use existing frequencies and bandwidth across the globe. There are extensive

Q&A's addressed about the system, how it works, and how it will be used on the official DRM web site at

www.drm.org/newsevents/globfaqs.htm

Q. So I all I need is an RX-320D, or to have my existing RX-320 factory modified (see below for details on this)

and I can plug the I-F output of the radio directly into my computer's soundcard and start hearing DRM

broadcasts, right?

A. No. You need to have a capable radio, and you also need to have software for decoding DRM signals. This

software is only available through the consortium via the DRM Software Radio web site located at

www.drmrx.org. It is not available through Ten-Tec or any other distributor. There is a list of specific computer

operating system and sound card requirements to be able to successfully decode DRM signals. The list of

specifications is on the DRM software purchase page located at www.drmrx.org/purchase.php. The last

specification listed is "suitable front end with 12 kHz output......" - that's the RX-320D.

There are two Digital Radio Mondiale websites that provide a lot of information about this revolutionary new

transmission capability.

www.drm.org is the DRM consortium website.

Users have made the following comment about the rx320d

"Using a 90' long wire as an antenna, I regularly get several of the European and N. African BC stations between

150kHz. and 250kHz, sometimes, well before nightfall."

No noise blanker or notch filter. Popular among Linux users because the hardware protocols are open source. All

commands are sent at 1200 baud via the serial cable, which means it can be controlled by any computer with a

serial port (or by some calculators).

The radio is not as well shielded as the Winradio and suffers from interference from the computer needed to

control it. Placement of the receiver in reference to the monitor and DSL modem can eliminate most interference.
