INTRODUCTION
 | The SSR-1 Receiver provides precision tuning over the short wave spectrum of 0.5 to 30 MHz with capability of reception of AM (amplitude modulated), C W (continuous wave) and SSB (Upper and lower single side band) signals. |
| A synthesized/drift canceling 1st mixer injection system giving 30 tunable ranges from 0.5 to 30 MHz is derived from a single 10 MHz crystal oscillator providing frequency stability necessary for SSB operation. |
| A stable low frequency VF0 tunes each of the 30 - one MHz ranges with a dial accuracy of better than 5 kHz which is sufficient to locate and identify a station whose frequency is known. |
| Separate detectors (product and diode) are used to provide for best performance whether listening to SSB or AM s i g n a l s . Narrow band selectivity for SSB and wide band selectivity for AM reception is provided. |
| The SSR-1 has a built in telescopic antenna or may be connected to an external antenna for better results. The sensitivity of the receiver is such that it operates near the thermal limit and when using the telescopic antenna the performance reaches external noise limits. |
| A manual tuned preselector provides for maximum sensitivity and maximum interference rejection. |
| Solid state circuitry is utilized throughout the receiver design allowing efficient operation from the built in battery supply or from an external DC or AC power source. |
| The SSR-1 Will bring you many hours of enjoyment when you discover the quality, ease of operation and usage possible with your receiver. The more serious or international radio listener Will obtain maximum enjoyment from the SSR-1 with help from more detailed manuals such as the "World Radio TV Handbook" and "Short Wave Listener’s Handbook". |
