I think this is a good response and I agree with the list of options but not
sure about the NB. Is anyone having good success with the NB in a fixed location ? I am on my second K2. First was in the 3800 SN range and this one is near 4400. I thought maybe something was wrong with the first one as it did not even change the audio tone or anything. The second one is the same way. I was assuming that maybe if I had sparkplug noise in a mobile environment, it would help, but if I was going to build K2 #3 it would NOT have buy the NB. I really miss the NB and NR on my Pegasus. Anyone else have better results? 73, Rich kd0zv ----- Original Message ----- From: "Robert C.

Most of the time I couldn't operate in my location without
the NB option. It's the best blanker I've ever used and FAR superior to the blanker in my IC-765. Of course the type of noise determines how well the blanker will work..guess I'm just "lucky" to have the right kind!

Is anyone having good success with the NB in a fixed location <snip> Rich, You are right - depending on the location you may have much use for the NB. There was a time I wondered if mine worked because I seldom have the kind of noise it works on. But occasionally I do get some noise, I still don't know from where, that it does work on and it really makes a difference. So, even though I seldom have to use it, I am glad I do have on those few occasions when it is needed. Another reason for having it is that you never know where you might end up using a rig that is so portable.

I built the NB option for my K2 #4168 and was convinced for several months
that it was not working. Nothing in my arsenal of test gear is able to check this particular feature for operation, this being the one item of test equipment that I have never seen a design published nor have located on the surplus equipment market. Probably some form of mini spark transmitter would be called for. Then one day by chance found that the NB was indeed working very efficiently on one particular type of impulsive noise. Depends where you live and what type of noise is giving problems as to the usefulness of the NB. Probably good on auto ignition interference and maybe static rain type of noise, though neither of these occur too often at my location on HF. The NB on my JRC NRD-515 HF receiver is similar in being choosy on noise type. The NB will be of more use when the K2 is used as a transverter source on the low VHF bands where auto ignition interference can be more of a problem. As an off topic subject on interference, the auto ignition interference may be aggravated by misguided technicians fitting non resistive spark plugs when servicing. The service shop I use for my small 4x4 is convinced that the correct resistive spark plugs when tested on their engine testing computer are inferior and would fit the non resistive type during services if not requested to use the resistive type. Does seem to make a difference in keeping down the ignition interference on 2m on my FM mobile radio receiver.

It depends a lot on the type of noise. The NB should help with ignition
noise, but may have little effect on atmospheric, power line or some other types. I find that the NR in the KDSP2 helps a great deal with noise here, more so on CW than SSB (but I haven't played much with the NR settings on SSB). 73, Bob N7XY On Sun, Sep 12, 2004 at 02:16:07PM -0500, Rich McCabe wrote: > I think this is a good response and I agree with the list of options but not > sure about the NB.

Well it appears my NB is probably working but does not doing anything with "my type of noise" based on everyones comments.
As I mentioned, I miss the NB on the Pegasus. Maybe Elecraft will come out with another type of blanker for those of us with just atmospheric noise :) Until then, I will just keep flipping it on/off waiting for that change when the noise is the right type... Wooo Hooo :) Not complaining as the K2 rarely needs it. Just dont think I would lay down cash for that option the third time. Yea, OK I probably will. I dont like blank spots in my K2!!! 73, Rich ----- Original Message ----- From: [hidden email] To: [hidden email] ; [hidden email] Sent: Sunday, September 12, 2004 8:00 PM Subject: Re: [Elecraft] Re Newbie I built the NB option for my K2 #4168 and was convinced for several months that it was not working.

Rich, you will be glad you have that noise blanker in there if you ever take it portable to a campground, or if someone parks a FORD
truck near your house with the engine running. Especially if you're trying to work a weak one on the higher bands. I use my K2 for mobile CW, and the noise blanker is VERY effective. I had a 93 Mercury Sable (Ford Motor Company product) that was VERY noisy ignition wise, and the K2's NB made mobile operation very pleasant. Without it, signals would have to be S9+ to even hear them over the racket from the ignition.
