We find it too much of a stretch between 40m and 80m in the late afternoon, but unfortunately don't have a 60m allocation here yet.<br /><br />By the way, it would have been a nice thought to correctly adjust the phase of the FSQ picture you show on the web page. It doesn't give a good impression with a misaligned picture!<br /><br />73,<br />Murray ZL1BPU<br />Developer of FSQCallAnonymoushttps://www.blogger.com/profile/15678838121963504076noreply@blogger.comtag:blogger.com,1999:blog-26675683.post-19769804047936144142015-05-15T18:32:49.583+01:002015-05-15T18:32:49.583+01:00What an interesting solution, and great article. ...What an interesting solution, and great article.

Wayne from Elecraft said that due to the ...Hi Dom,<br /><br />Wayne from Elecraft said that due to the design constraints and commercial imperatives "some radiation products may remain in the VHF through microwave region that cannot be easily eliminated." I had hoped that Elecraft might suggest that my KX3 is unusual in this respect and that it might have a problem that could be rectified, but they have never hinted at that possibility. It seems that the emissions are acceptable to Elecraft. I don't know if they are 'normal' for KX3s in general.<br /><br />David, from Elecraft said this:<br />"- There will be some emissions when cables are connected to utilize the various signals available on the KX3. This is expected with the Elecraft cables and cabinet.<br /><br />- We are investigating ways to reduce emissions but, at this time, there are no solutions available from Elecraft.<br /><br />- As workarounds, here are some suggestions to mitigate the effects:<br /> - Terminate cable jackets to the chassis. This will involve fabricating interconnect cables to do so.<br /> - To further reduce emissions, filtering of the cables may be possible.<br /> - Ensure that all metal contact points on the chassis are clean and well secured."<br /><br /><br />My main problem with these emissions (other than the simple fact that I wished the KX3 was cleaner in this regard) is that they cause problems for some spectrum sensing software that I occasionally run, scanning the UHF mil-air band. The spectrum sensing application has a really hard time anyway, due to the intermod problems I have but the KX3 emissions really bogged it down with false positives from those harmonic spurii when I was band hopping and QSYing on HF.<br /><br />I managed to achieve about 20dB suppression for the spurii in the UHF mil-air band with the mix #61 ferrites. That seemed to mitigate the issues I had with UHF spectrum-sensing to a tolerable degree, but I'm not all that happy with the notion that these emissions should acceptable both to the manufacturer and the consumer.<br /><br />Out of curiosity, I just decided to see if I could find a sprog from the KX3 related to whatever frequency it was left on. I turned it on and found it sat on the 20m JT-65 frequency, 14.076MHz. I tried looking for a spur on the 100th harmonic, at 1.4076GHz, with my FCD-Pro+ and found it immediately peaking 26dB above the noise floor, receiving it through a discone antenna in my loft, as in the blog post. It is nearly 50dB above the noise floor using the same receiver and a collapsed telescopic whip in the near field. This is with all the #61 ferrite still applied.<br /><br />Thanks for your interest in this matter.<br />73.<br />Darren, G0HWW<br /><br /><br /><br /><br />g0hwwhttps://www.blogger.com/profile/18274132625698139495noreply@blogger.comtag:blogger.com,1999:blog-26675683.post-70557955259561548752014-09-12T12:05:15.783+01:002014-09-12T12:05:15.783+01:00Hi....

Please correct my misunderstanding if there is one... the 'cure' seems to be apply common mode chokes using -61 on all the cables leaving the KX3 if I read the blog correctly. Probably by accident I currently run with most cables running through TDK clip on using -61 already so maybe I have been lucky.<br /><br />I briefly looked at a USB SDR RX on the c360-400MHz region but couldn't see the peaks being mentioned coming from either KX3.
