Re: [Elecraft] Noise Blanker settings for Newbies
1. It really helps if you put the particular Elecraft product you're writing about in the subject line. From reading way down, it "appears" it's a K3. 2. We moved last year from a rural location [38 years] and I have no electric fences around us now. For the 38 years on "The Farm," I was surrounded by them, including ours. If ever there was a noise source suited to complete extinction by the K3 NB, it's an electric fence, and the IF NB alone on mine totally removed all of them. The pulses are short, generally NAR2-3 did it for me. One of them had the old fashioned solonoid with the swinging core, and sometimes [in rain], it's pulses were long enough that NAR4 was necessary. I never needed or used the DSP, and the IF NB has no discernable effect on the received signal. 3. I have no idea what you're referring to with "NB light," my K3 does not have such a thing. There is an indicator in the main display, "NB", which comes on when I turn NB on and goes off when I turn NB off. It doesn't do anything when I transmit. I'd suggest a read of the K3 manual first, then KE7X's excellent manual if you have it. If you don't, I suggest you buy it, it's inexpensive and approaches the K3 [and other K-line products] from a different perspective that a User Manual. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 5/15/2016 10:04 AM, Mike Smith VE9AA wrote: 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.

Re: [Elecraft] Noise Blanker settings for Newbies
You need to spend some quality book time and walk away from the radio until you understand how it works. Read and *understand* the *whole* manual once through before laying another finger on the radio. I would suggest the KE7X books as well as the manual(s). You first need to find out what version of firmware is installed and if woefully out of date, which I suspect, update that before changing anymore settings. The days of unpacking a radio, putting it on the desk, plugging it in and having it work like you expect are over.
