Receiver Table Legend:
       
    3 dB blocking (gain compression) test done at 100 kHz to eliminate phase noise interaction
   F.L. = Filter limited, no measurement was possible due to signal leakage around filter
   N.A. = Data not available
       
a Measured with SSB filter
b Built-in Preamp actuated
b1 Built-in Preamp 2 actuated
b2 Built-in Preamp set at 20 dB. Adjustable to 10, 20 or 30 dB
c Readings would have been lower if 2-kHz spacing had been possible
d Dynamic Range is 90-dB at 100-kHz spacing
e 20-kHz Dynamic Range is 66-dB
f Measurement was Phase-Noise Limited = ARRL RMDR (Reciprocal Mixing Dynamic Range)
g Audio DSP Enabled
h AGC Off
i At 1 kHz dynamic also 95 dB but with 300 Hz roofing filter enabled
j At 1 kHz, noise limited to 68 dB
k At 1 kHz dynamic range was 66 dB
l (lowercase L) Reserved
m Receiver was optimized by Malcom Technical Support for best dynamic range
n Measured with 3 kHz roofing filter
o Measured with 6 kHz roofing filter
p with 200 Hz 5-pole filter
q with 400 Hz 8-pole filter
r with 500 Hz 5-pole filter
s Using ARRL 3-Hz bandwidth blocking method
t with optional roofing filter
u without optional roofing filter
v At 1 kHz performance is opposite sideband rejection limited
w At 1 kHz dynamic range is 104 dB
x "Long Form" report available by e-mail request.
2-kHz RMDR: 6M=91dB, 10M=92dB, 12&15&20M=87dB, 17M=85dB, 30M=98dB, 40M=92dB, 80M=94dB & 160M=95dB
