DESCRIPTION 

The RR-2 19" rack mounted is similar to the RR-1 but with continuous coverage provided by a frequency synthesizer which generates an injection signal every 500kHz and PTO which tunes a 500 kHz range. PTO over-travel allows an additional 50 kHz off each band edge. The RR-2 is classified as a marine "reserve" (i.e. backup) receiver.

bulletFrequency Range: 150 kHz - 30 MHz
bulletModes of Operation: USB, LSB, AM, (RTTY with RY-4 accessory installed).
bulletFrequency Accuracy: Within +- 1 kHz when receiver is calibrated to the nearest 100 kHz point, against the internal 100 kHz calibrator.
bulletFrequency Stability: Less than 100 Hz for any 8 hour period after warm-up at 25°C ambient temperature, with less than +- 10% variation in supply voltage.
bulletSensitivity : (a) Antenna impedance, 10 Ohms in series with 250 pF.

Above emf values are open circuit voltages.
bulletImage Rejection:
Better than 60 dB below 15 MHz. Better than 50 dB above 15 MHz
bulletRF Blocking: An undesired, unmodulated signal, 100 dB above 1 micro volt 20 kHz above or below desired signal will not reduce the desired signal more than 3 dB, as measured at the receiver output. The desired signal has a level of 60 dB above 1 micro volt and is modulated 30% at 1 kHz.
bulletCrossmodulation: an undesired signal 90 dB above 1 microvolt, modulated 30%, at 1 kHz at a frequency removed more than 20 kHz above or below a desired A1 (CW) signal, at a level of 60 dB above 1 micro volt, will not produce interference greater than 30 dB below standard output for the desired signal.
bulletIntermodulation: Between 405 and 535 KHz, two interfering signals must have a level of 80 dB above 1 micro volt or more to give products equal to standard output. The reference signal for this measurement is 20 dB above 1 micro volt. Between 1.5 and 30 MHz, the interfering signals must be 65 dB or more above the reference signal of 30 dB above 1 micro volt.
