How would you rate the NB in the IC-7300 compared to the one in the IC-7700 ? I never used a 7700 but the IC-7300 NB is more effective on my local power line noise than my Elecraft K3 (which does pretty well)

Hi Ron,

I owned all the radios in the 756/756Pro series from 1998 to 2008, and never found their noise blanker implementation satisfactory. The first viable NB I encountered was in the IC-7700.

I have made it a rule never to keep more than two generations of technology in my station, so all the old analogue radios (725, 728, 729, 751A, 765, 781) are long gone - except for a mint IC-703+. The present state of propagation makes me wonder whether I can justify even one HF radio, but I need a station as a test bed.

I had two HP 8640B's, but a Marconi 2018A and 2019 (made in England) replaced them in 2010. The Marconi's have better phase noise, especially in the 0-200 Hz offset range. The fan driver circuit in the 8640B ruins the low-end phase noise of the instrument.

Not being in a particularly noisy environment, I'm not able to give you much insight about pulse-noise performance. But the IC-7300 Noise-Blanker does have three adjustable parameters.

Gigaparts, HRO and Main Trading all have a black Friday sale on the Icom IC-7300 ($999.95 after $100 rebate). Best part is the wife said I could get one :) Bad part is that I tend to over analyze things and sure enough I'm doing it with this radio.

Question for the group - do any of you have firsthand experience with this radio especially in an environment with high noise (power lines mostly I think). I've read it doesn't do well in high noise environments and that's the thing that's keeping me from buying it.
