[Yaesu] Noise blanker recommendations

[sq7d at onet.pl]

 Hallo

Here is a sample of NB from 9000D on 80m with dipole (quiet) and vertical (noisy)

 I was making a rather serious (given my small antennas) effort today in the



Illinois QSO Party and had to deal with this intermittent noise I have here



for pretty much the entire contest.  It is a raspy, hash type noise that



will be on for 2 or 3 seconds, then will end, but come back every 20 to 30



seconds.  I  have figured out it is not in my house, and doesn't seem to be



power line noise.  At one time I thought I had localized it to a house



about 4 houses to the west of me, but the house is now unoccupied, but the



noise is still there.







Anyways, I was using the Kenwood TS950SD which I just picked up, and it is



a great rig with lots of receiver tools.  The noise blanker pretty much



knocked out the noise, but it also produced plenty of IMD products when the



band got busy and put a raspy sound on many of the signals, so I was having



to turn the NB off and on trying to make the signals as best as I could



with this noise.  Even engaged the attenuator a few times on 40m which



helped a little, but also weakened signals.







I have had a slight windfall recently and can afford to get a newer, better



rig if I want.  Are there any recent Yaesus that have noise blankers that



take out many different types of noise, but don't mess with the receive



signals and receiver dynamic range?  I wonder if the DSP based noise



blankers are better?  An older rig would be ok also if it would meet those



criteria.
