Nobody at Elecraft has been able to explain to me why the new DSP board I received some time ago has had such a profound affect on my K3. It was not supposed to. Mainly, in improved AGC. Also improved uniformity of Rx Gain between my K3's #272 and #2308. The DSP board upgrade has been the single biggest improvement I've seen in the K3 since getting it 2 years ago.
I saved all my previous firmware loads and took them all the way back with the new DSP board as a test. I could not make the K3 behave the way it used to (in a less desirable manner) with any of the old firmware or DSP loads. If you are not an AGC focused operator (most CW guys are), or if you use headphones - you may not notice to the extent that I did. But if you are - a DSP board upgrade would be a deal at twice the cost... IMO YMMV, etc. [Elecraft] K3: LPF, bass audio, new DSP board: Stirring the pot?

Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Jim, This is the problem I've experienced, and why I think my receiver is "noisy." I can hear a high frequency whine or tone that only gets worse if I adjust the receive EQ to enhance voice intelligibility. This can make working weak signals fatiguing. I should probably just cough up the money and swap out DSP boards for a new one with an LPF installed. However, I'm not too thrilled about the unannounced price increase from 69 to 89 dollars. Had I known, I would have ordered one earlier. 73 de James K2QI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
