6、n-Tec, Inc 1185 Dolly Parton Parkway Sevierville, TN 37862 Copyright Ten-Tec Incorporated Downloaded from www.M manuals search engine Rx-321 Receiver The RX-321 receiver was deisgned by Ten-Tec for OEM applications. It was manufactured by Ten-Tec under agreement with third parties and never produced

7、 with the Ten-Tec brand name. The RX-321 is based on the RX-320D receiver. Addional circuitry to support integration with a transmitter was added, along with an RF preselector and 600 Ohm audio output. GENERAL DESCRIPTION The Rx-321 is a general coverage receiver capable of receiving AM, SSB, and CW

8、 signals from 100kHz to 30MHz. The receiver is controlled by an external computer via a serial connection (see to download the Rx-320D PC-GUI and programmers reference guide which will provide more information on controlling and programming the Rx-321). The Rx-321 is powered from any DC power supply

9、 operating in the range of 12-28VDC and capable of supplying at least 800mA of current (please observe the correct polarity as shown on rear panel). The antenna connection is designed for a 50-ohm antenna and is an SO239 type connector. The speaker connection is also available on the rear panel and

10、is clearly marked. Please connect a 4 to 8 ohm speaker (again, please observe the correct polarity as shown). Finally, there is also a 9-pin connector on the rear panel labeled REMOTE. This connector provides an optional 600- ohm audio output and a mute pin that allows the AGC circuit to be turned o

11、ff when used with an external transmitter (this keeps the external transmitter from loading up the AGC and causing receive recovery problems). Please see the schematic description of the 9-pin connector labeled remote for the pin out of this connector and DC voltage levels to apply to the mute pin w

12、hen using an external transmitter. SCHEMATIC DESCRIPTION The receive signals from the antenna pass through one of eight preselector filters that are selected based on the band in which the receiver is tuned. From there, the selected signals go through a preamp stage before passing through an IF notc

13、h filter and on to the first mixer. The first mixer translates the tuned signal to 45MHz. The 45MHz signal then passes through a 45MHz IF filter and gain stage before going to the second mixer. The second mixer translates the signal to 455kHz. The 455kHz signal then pass through a 455kHz IF filter a

14、nd gain stage before going to the third mixer. The third mixer translates the signal to 12kHz where the signal is then passed on to the AD1847 codec and ADSP- 2101 DSP processor for decoding and translating to a low-level audio signal. The low level audio signal is then passed on to an audio amplifi

15、er which amplifies the signal and passes it on to the external speaker connector provided at the rear panel. An external speaker can be connected and the received signal can be heard.
