Mike, I think Bill was alluding to my answer which on the face of it didn't make any sense, but what I was trying to determine was whether stray RF may have been doing something to the K3 NB circuitry during transmit as you suggested you thought the NB started to flash after transmitting, hence my suggestion to eliminate any possibility by using a dummy load, that's all.
Now thanks to the group we have the correct answer, the NB annunciation legend can flash when the I.F. blanker setting is too high for the signals. It will stop flashing when transmitting and start again back on receive. I should have searched the electronic manual, that is what I generally do in iBooks on the iPad where I keep all my radio manuals. It is generally easier than manually searching the paper copy which is safely stored away in a file. I don't own a K3, hence me not knowing about the significance of the flashing NB, I use the KX3 and find the noise blanker works very well on powerline noise, narrow pulses, ignition spark type noise. I would find it strange and disappointing if the K3's blanker was poorer than the KX3's. What is puzzling is that you say it electric fence pulses that the NB is struggling with, I would have thought that is one of the easiest things to blank out, a simple I.F. Blanker shouldn't have a problem with that. Like so many controls that give you a lot of user settings there are benefits and also problems, mostly the defaults are a good starting point, but changing too many settings at once will not help. You have to be methodical and change one thing at a time and see what the effect if any is. I have used the KX3 as my main rig for more than a year and am still finding things about it that I didn't know. It's part of the joy. 73 from David GM4JJJ > On 16 May 2016, at 00:06, Mike Smith VE9AA <ve...@nbnet.nb.ca> wrote: > > I am not sure what you are eluding to Bill, but suffice to say I don;'t > think you understand the issue. > Once I have transmitted, the NB flashes and will stay flashing forever. > (while I am sitting there receiving) > Also, the NB seems to do little to nothing. > > I am not a K3 engineer, but I am now SURE this is not how it's supposed to > work. > > I am going to crack the radio open tomorrow and see if the board has come > loose during shipping. > > Please don't anyone email me again asking me to look at the page in the > manual concerning the NB.
