[Elecraft] K2 Signal to Noise on 160m ?
Is there normally high noise on 160m with a K2 ? Comparing the K2 to an old Ten Tec Delta the k2 signals seem to be lower and noise higher. A sharp sizzling frying pan noise was pronounced on the K2 and uncomfortable to listen to but barely there on the Delta. This a used K2 and I adjusted the STP (Sidetone Pitch) to my liking and wonder if that messed something up or is the K2 noisy on 160m ? This is the QRP K2 with ATU but no Noise Blanker or DSP.

You don't give so much information here about how you did the sidetone pitch adjustment, but it is easy to mess up things if you do that without adjusting filters also.

Re: [Elecraft] K2 Signal to Noise on 160m ?
The K2 sensitivity and receiver noise floor will not change much from band to band. In fact, with proper filter alignment, the internal receiver noise may even be more quiet on 160 than on other bands. You probably should not be using the preamp on 160 unless you have a low noise receiving antenna. For information on filter alignment for the K2, look at the K2 Dial Calibration article on my website www.w3fpr.com. You can also find information about using Spectrogram for the K2 alignment on the newly mirrored N0SS (sk) website at http://www2.opparc.org/mirrors/n0ss/www.n0ss.net/wsdindex.html 73, Don W3FPR On 11/24/2013 9:52 AM, Jimithy66 wrote: Is there normally high noise on 160m with a K2 ?
