Re: [Elecraft] K2 SSB crystal filter set lacks calibration value

Mark, The SSB reception will work, but the passband may not be positioned optimally. Same goes for the CW filters, they will work but may not be centered at your desired sidetone pitch. The audio Spectrum analyzer is easy to obtain.  Go to my website www.w3fpr.com and scroll down on the

Thanks, Don. If I lack the spectrum analyzer and noise generator to perform the refinement, what sorts of outcomes can I expect? Will the SSB option work, but sub-optimally? On Fri, Apr 6, 2018 at 8:03 PM, Don Wilhelm wrote: > Mark, > > Assume it is 3.6 for the initial

Hi John, I operate mostly 6 & 2 meters. On 6m, I have a third preamp between the K3S and the amp. When operating EME, I have to disable Preamp 2 because 3 preamps create too much noise. So, I have disabled Preamp 2. This has allowed me to work EME successfully. I wanted to try an
