So it seems no matter which IF NB setting I have the rig on, the NB will invariably start to flash once I start transmitting. Maybe I don't understand what I am doing (quite possible), so this is what I am doing. See if this sounds correct.
I hear my neighbours electric fence driving me crazy, so I hold in the NB button. As I understand it, I can adjust either DSP NB and/or IF NB. OK, if I leave IF alone and only choose DSP NB, I can run it through a range of DSP T-1, 2 & 3, up to a max of T3-7 (which makes the audio sound all crunchy) using the VFO(a) knob. I can get 'some' satisfaction from the DSP NB, but would like the option of using either/or. I can transmit as much as I want and the NB light never flashes (using the DSP NB). No problem. Scenario 2.....hold the NB button in, now using the VFO (b) button (for the IF NB), I can choose NAR(7 choices),MED(1-7) & WIDE (also 1-7) . None of the IF choices really seem to do much against the electric fence noise except maybe WID3 one minute, then NAR4 the next. (yet the pulsing is exactly the same every pulse and other rigs (Icoms, Yaesu's deal with it easily)-the e-fence is a pop pop opo, never changing. What's even odder, is that once I transmit once or twice, the NB will then flash, and it seems to me the NB is no longer engaged - is that correct?....is the flashing a warning that you do not have the best selection or a warning that it's now disengaged? Is there a separate board for the NB, because it sure seems to me like it's not working as intended. To add insult to injury, my ol' IC-7410 right next to it pretty much eliminates the E-fence noise altogether w/o breaking a sweat. (I know I shouldn't use the word ICOM here (hi) and I just can't believe this Icom box would be better than a K3.everything I have ever read says the K3 should be superior in every way. I did all my testing on an extremely quiet 17m band, CW mode, 500Hz filter. No amount of varying the bandwidths, hi cut, locut, or an array of filter choices, modes or bands seems to have any affect on the NB flashing. (or it's poor effectiveness) Ideas? Sub 100 serial number K3 CW mode, 20m, low SWR. Mostly using the 500Hz filter. I don't know the radio at all. . . .but I press NB, twizzle with VFO A and VFO B and get things set to where I think they should be to dampen my neighbours electric fence noise, but after a couple of short transmissions I hear the rig clicking away (relays) and then I see the NB flashing (it's evidently unhappy with my DSP choices), so another round of twizzling. Maybe I have it set too wide.....too narrow......not close enough matching.....scratch my head. After a half hour of various settings and looking in the manual (and then in the mirror to see if I have stupid written on my forehead) I come here for sage words of wisdom. Is there something obvious that I am doing wrong? I have no idea what S/W revision I am using and barely know most of the options the rig has and cannot ask the PO . Help>?! Thanks for the nice welcome guys and I can certainly get a S/W version (if that's important to this discussion) Mike VE9AA Mike VE9AA Mike, Coreen & Corey Keswick Ridge, NB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
