Hi Barry, Thanks for your input. Yes, I believe we included direct sampling digital receivers (SDR) versus superhet receivers.
The post I made here today is not complete; rather that re-post everything, I included a link to the early August discussion, which explained in detail what I meant. This is what I asked: "I'd like to know whether it's ever been established that some very talented hams can out-hear the best SDRs and/or DSP available. Can a skilled ear-brain combo (such as some highly-skilled and talented 160 meter contesters) beat state-of-the art digital signal processing when it comes to copying the very weakest of signals buried in the noise? "I always thought Linrad was the best DSP software, though I never got it working right here (older sound card issues in Xubuntu). "I asked the following question at http://www.eham.net/ehamforum/smf/index.php?topic=104388.msg861047#msg861047 : "Are there any people who can hear weak signals with a good analog receiver, who --if they could instantly switch their antenna and headphones from the analog RX over to the best SDR made today-- simply couldn't hear any better with today's best SDRs and/or DSP software?" "There's been a few opinions, but how about multiple valid tests?" There were a number of replies, both on the Linrad and the Topband reflectors. Sounds like you don't agree with most. What direct-sampling receiver did you mean? 73, Mike www.w0btu.com On Mon, Oct 12, 2015 at 6:53 PM, Barry N1EU <[email protected]> wrote: > On Mon, Oct 12, 2015 at 10:28 PM, Mike Waters <[email protected]> wrote: > > > But as a recent thread here* established, there is *NO* SDR that can > > perform as > > well as a good ear-brain combo for copying the very weakest of signals > > buried in the noise.
