Many early teletype listeners started their monitoring hobby with teletype readers. Readers have fallen out of favor in recent years because of their limited performance, limited mode coverage and lack of features. The Universal M-450v1.5 reverses this trend, providing a high quality demodulator, extensive mode coverage, state-of-the art display parallel printer port and RS232 serial port (includes control program on 3 1/2" disk). The Universal M-450v1.5 incorporates capability never seen in a reader before. The M-450 provides all the benefits of a reader, without the limitations. The M-450 is totally self contained; there is nothing else to buy. It is compact and operates from 12 VDC making it a natural for auto or boat installations. The two line liquid crystal display provides a (40) forty characters readout (not just 8 or 16 like other readers). This super-twist LCD can be read from any angle, and the front of the M-450 is sloped to provide the optimum in viewing and operating convenience. An 8000 character scrollable buffer stores incoming text for your review. LED indicators for Mark, Space, Input and Data are provided. A gray, all metal cabinet provides a solid look of quality. The rear panel has Audio Input, Discriminator Input, Parallel Printer Port, RS-232 Serial Port and 11-15 VDC input. For the shortwave listener, the M-450 provides all the standard reception modes ... and then some. The M-450 is the affordable accessory for every shortwave listener!
