b0	No preamp actuated
b	Built-in Preamp actuated
b1	Built-in Preamp 2 actuated
b2	Congenital-in Preamp set at xx dB. Adjustable to ten, 20 or 30 dB
b3	Congenital-in Preamp ready at 16 dB
b4	Built-in Preamp set at 32 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	xx-kHz Dynamic Range is 66-dB
f	Measurement was Phase-Dissonance 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
grand	At 1 kHz dynamic range was 66 dB
l	(lowercase L) Reserved
thousand	Receiver was optimized by Malcom Technical Support for best dynamic range
northward	Measured with 3 kHz roofing filter
o	Measured with 6 kHz covering filter
p	with 200 Hz 5-pole filter
q	with 400 Hz eight-pole filter

s	Using ARRL 3-Hz bandwidth blocking method
t	with optional covering filter
u	without optional roofing filter
5	At 1 kHz performance is contrary sideband rejection limited
w	At i kHz dynamic range is 104 dB
x	"Long Form" report available by email request. 2-kHz RMDR: 6M=91dB, 10M=92dB, 12&xv&20M=87dB, 17M=85dB, 30M=98dB, 40M=92dB, 80M=94dB & 160M=95dB
y	DR3=108 dB with 20 dB preamp ON, and 99 dB with preamp OFF. Otherwise dynamic range contained of signal spacing. Note: Tests in 2022 of a 2d 6700, and by the ARRL of a 6500, no longer measured a dynamic-range increase with the preamp ON. The 108 dB value is no longer valid. 2 kHz dynamic range is 99 dB, same as 6600M. As with any radio, only utilize a preamp if it improves re-create, and commonly only on 15m and up.
z	The low-side dynamic range was 76 dB, while the high-side dynamic range was 70. NOTE: This may imply the roofing filter was asymmetrical, and probable a sample variation.
aa	Measured using i.ii kHz roofing filter.
ab	Measured with IP+ ON.
air-conditioning	Measured with dither and random OFF Notation: Icom calls "dither and random" IP+. Noise floor may be affected by dither and random.
advertizing	Measured with Dither and Random ON NOTE: Dither and Random convert intermodulation products into broadband racket.
ae	AGC threshold adjustable Notation: AGC threshold should exist ready about half dozen dB to a higher place band dissonance.
af	Measured with third test tone. NOTE: ARRL may examination dynamic range (DR3) of directly-sampling radios with a 3rd examination tone to approximate a crowded band. The validity of this examination method is questionable.
ag	DR3=96 dB with twenty dB Preamp ON. (99 dB Preamp OFF) Otherwise dynamic range contained of indicate spacing. Annotation: Testing of 2nd sample made on 10 meters while investigating IFSS* curves. Like testing of 2nd sample of K3S, as well made on 10 meters. * IFSS = Interference gratis bespeak force.
ah	Annotation: Testing of 2nd sample made on 10 meters while investigating IFSS* curves. Similar testing of 2nd sample of Flex Radio 6700, as well made on 10 meters. * IFSS = Interference free signal force.
ai	NOTE: Dynamic range testing of a second 6300 sample resulted in a modestly higher dyanmic range measurement.
aj	NOTE: Test information for 6600M is after May 2022 PEN (Product Enhancement Observe). Due to the insertion loss of vii-pole bandpass filters on the contest bands, recommend +sixteen dB preamp during daytime on 80 -17 meters if in a quiet location. 15 - 6 meters may crave +32dB preamp for an adequate racket floor.Tested with Blastoff 5. 2.2.7 software.
ak	Some variation in dynamic range was noted later on an extended warm-up.
