[Elecraft] Question about KNB2 Noise Blanker (Gain reduction in NB2 position)

Hello all, I just completed the KNB2 and added it to my K2 transceiver. All menu indications are as they should be and the blanker seems to be working correctly in the NB1 mode at both HI and LO THR settings. The receiver gain seems normal. I have a question about using the noise blanker in

[Elecraft] K2 running QRP

Hi, I know I read sometime a message telling that we must use the K2 at a maximum power level of 10W to prevent such overheating, or final to blow.. I'm not sure if I dream it or it is a real concern. Yesterday, I checked my K2 running at full QRP power on every band using the dummy

Re: [Elecraft] K2 running QRP

Jean-Francois, Whether you can run your K2 at full power or not depends on the duty cycle. For data modes where the duty cycle is 100%, the answer is NO - in fact you should keep the power down to about 5 watts for continuous duty modes. For CW and SSB, operating at 14 watts should present

[Elecraft] KAT100 - PWR Range LED - Is this normal ?

Hi, My setup is a K2 into KPA100 KAT100 mounted in an EC2 case. Linked via a KIO2 and serial cable to the KPA100. With the kit running into a dummy load I do the following. a) Set the Power control fully CW. b) Press Display Tune together and get maximum power out. c) The HIGH LED on the

[Elecraft] Filter alignment

With my last few days of vacation time remaining, I decided to do one of those I'll do it later projects. Inspired by my shiny new Heil mic, I thought I'd visit all my filter calibrations and settings, as it hasn't been done since the original build. I've been to the Tech Notes page and saw

Re: [Elecraft] Question about KNB2 Noise Blanker (Gain reduction in NB2 posit...

I've had the opposite luck. My K2 takes out local electrical noise and ignition noise where my TS-570S and IC-746 noise blankers didn't do a thing. I've been very happy with the noise blanker in my K2 and think that's been the best option for the buck!

Chuck, I believe you will find the information in the K2 Dial Calibration article on my website useful - www.qsl.net/w3fpr. That article contains information both on setting the 4 MHz reference and setting the filters/BFOs. There are links ot other resources within the article. 73, Don

Re: [Elecraft] Question about KNB2 Noise Blanker (Gain reduction inNB2 posit...

I find the KNB2 in my K2 to be very effective on the usual type of powerline noise I encounter. However there is a variant, which sounds the same to the ear, that the blanker won't touch. I don't have a 'scope so can't look at what the difference in waveform might be, but in general I am quite

[Elecraft] K2 DSP vs SCAF audio filter

Gentlemen and Ladies, Have any of you compared the K2 DSP with a SCAF audio filter ? I have a SCAF and am considering the K2's integrated DSP but really wonder if there, in the end, will be a significant change in my ability to copy weak signal CW signals. Regards, Brian n6iz

Re: [Elecraft] K2 DSP vs SCAF audio filter

I am not as descriminating as many on the list and I operate cw almost exclusively. I have the DSP and know that it works well and is occassionally useful. However, the stock filters in the K2 are so good that I rarely use the DSP filters or de-noiser. SSB may be a different story though.

Re: [Elecraft] T6 continuity checks

Mike: If you look at the schematic, you'll see that pin 3 of T6 is attached to pin 2 of T6. You should get continuity between all leads. If you DON'T, something is wrong. Continue with your building... 73's, John AA0VE Mike wrote: I just finished installing T6 on the RF board, and did
