M RECEIVER
• Receiver system : Double-conversion superheterodyne
• Intermediate frequency : 1st 69.45 MHz (13.35 MHz: WFM)
2nd 450 kHz
• Sensitivity* : (except spurious points; typical values)
* FM and WFM are measured at 12 dB SINAD, AM is measured at 10 dB S/N.
• Squelch sensitivity : 50, 144, 440 MHz Less than 0.18 µV (Threshold)
1200 MHz Less than 0.25 µV (Threshold)
AM (50 MHz only) Less than 0.56 µV (Threshold)
WFM Less than 5.6 µV (Threshold)
• Selectivity (except WFM) : More than 15 kHz/–6 dB
Less than 30 kHz/–60 dB
• Spurious and image rejection ratio : 50, 144 MHz More than 60 dB
440 MHz More than 50 dB
1200 MHz More than 38 dB
(except half IF, 2nd image, 50 MHz band IF and WFM)
• Audio output power : 250 mW typical at 10 % distortion with an 8 Ω load
