Receiver Test Data

(Terms Explained: DOC PDF)

Sorted by Third-Order Dynamic Range Narrow Spaced - or- ARRL RMDR (Reciprocal Mixing Dynamic Range) if Phase Noise Limited

The term RMDR has only existed since 2012. To convert column LO Noise to RMDR, subtract 27 dB. Example: an LO Noise of 127 dB would be an RMDR value of 100 dB

Note: The term blocking only applies to a superhet radio. For a direct sampling radio the value in the blocking column is the ADC overload point reference receiver noise floor.

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

y DR3=108 dB with 20 dB preamp ON, and 99 dB with preamp OFF. Otherwise dynamic range independent of signal spacing.
NOTE: Tests in 2017 of a second 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 The 108 dB value is no longer valid. 2 kHz dynamic range is 99 dB, same as 6600M.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 use a preamp if it improves copy, and usually 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 likely a sample variation.

aa Measured using 1.2 kHz roofing filter.

ab Measured with IP+ ON.

ac Measured with dither and random OFF
NOTE: Icom calls "dither and random" IP+. Noise floor may be affected by dither and random.

ad Measured with Dither and Random ON
NOTE: Dither and Random convert intermodulation products into broadband noise.

ae AGC threshold adjustable
NOTE: AGC threshold should be set about 6 dB above band noise.

af Measured with third test tone.
NOTE: ARRL may test dynamic range (DR3) of direct-sampling radios with a third test tone to approximate a crowded band. The validity of this test method is questionable.

ag DR3=96 dB with 20 dB Preamp ON. (99 dB Preamp OFF) Otherwise dynamic range independent of signal spacing.
NOTE: Testing of 2nd sample made on 10 meters while investigating IFSS* curves. Similar testing of 2nd sample of K3S, also made on 10 meters. * IFSS = Interference free signal strength.

ah NOTE: Testing of 2nd sample made on 10 meters while investigating IFSS* curves. Similar testing of 2nd sample of Flex Radio 6700, also made on 10 meters. * IFSS = Interference free signal strength.

ai NOTE: Dynamic range testing of a second 6300 sample resulted in a modestly higher dyanmic range measurement.

aj NOTE: Test data for 6600M is after May 2018 PEN (Product Enhancement Notice). Due to the insertion loss of 7-pole bandpass filters on the contest bands, recommend +16 dB preamp during daytime on 80 -17 meters if in a quiet location. 15 - 6 meters may require +32dB preamp for an adequate noise floor.Tested with Alpha v. 2.2.7 software.

ak Some variation in dynamic range was noted after an extended warm-up.

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
y	DR3=108 dB with 20 dB preamp ON, and 99 dB with preamp OFF. Otherwise dynamic range independent of signal spacing. NOTE: Tests in 2017 of a second 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 use a preamp if it improves copy, and usually 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 likely a sample variation.
aa	Measured using 1.2 kHz roofing filter.
ab	Measured with IP+ ON.
ac	Measured with dither and random OFF NOTE: Icom calls "dither and random" IP+. Noise floor may be affected by dither and random.
ad	Measured with Dither and Random ON NOTE: Dither and Random convert intermodulation products into broadband noise.
ae	AGC threshold adjustable NOTE: AGC threshold should be set about 6 dB above band noise.
af	Measured with third test tone. NOTE: ARRL may test dynamic range (DR3) of direct-sampling radios with a third test tone to approximate a crowded band. The validity of this test method is questionable.
ag	DR3=96 dB with 20 dB Preamp ON. (99 dB Preamp OFF) Otherwise dynamic range independent of signal spacing. NOTE: Testing of 2nd sample made on 10 meters while investigating IFSS* curves. Similar testing of 2nd sample of K3S, also made on 10 meters. * IFSS = Interference free signal strength.
ah	NOTE: Testing of 2nd sample made on 10 meters while investigating IFSS* curves. Similar testing of 2nd sample of Flex Radio 6700, also made on 10 meters. * IFSS = Interference free signal strength.
ai	NOTE: Dynamic range testing of a second 6300 sample resulted in a modestly higher dyanmic range measurement.
aj	NOTE: Test data for 6600M is after May 2018 PEN (Product Enhancement Notice). Due to the insertion loss of 7-pole bandpass filters on the contest bands, recommend +16 dB preamp during daytime on 80 -17 meters if in a quiet location. 15 - 6 meters may require +32dB preamp for an adequate noise floor.Tested with Alpha v. 2.2.7 software.
ak	Some variation in dynamic range was noted after an extended warm-up.
6	6 meter data, preamp ON
