Hi Allen, I would be interested in your pin diode work on the Omni VI. I have seen Omni 6 + here that had sensitivity down to .10uv and others that were close to .6 or .7.. Even that, .6, is decent b

Glenn, if you could make audio recordings of the test you described showing good resolution by O6/Corsair and poor resolution by K3, you would be making a huge contribution toward the 2-year old deba

Hi Barry, Good idea.. I will try to set up soon and make a recording, however, the limiting factor, is still how well our ears/brains can decipher/separate two weak signals in the same passband, choo

Barry, I meant to comment on the Ten Tec O6 audio you mentioned. I too ran a remote a pre DSPaudio line to the rear panel on one of my O6. I fed that into a combo preamp/amp I designed using a 6CW4 n

Glenn, Wouldn't a true weak DX and pile-up simulation have the two strong signals at 2KHz and 2KHz plus away from the passband so that the mixing product(s) fall inside the passband? I've kept my Cor

Glenn, the key to success with tapping the audio pre-dsp is to add some analog low pass filtering with a turn-over freq in the 3000-3500hz region and fairly steep roll off. The Omni 6 is just TOO his

My two cents: - don't bother with the strong off-channel signal; the K3 and the O6 fitted with IR cw roofing filter will easily handle this - it's really not that important that the two closely separ

Hi Gary, Yes but the scope of my testing and interest thus far has been more about weak signals in a typical QRP sprint or simple weak signal work in the absence of contest conditions. The K3 or an O

Hi Barry, This has been my experience as well. But having some decent equipment on hand allows me to confirm my hunches.. Hi I do appreciate your feedback. Have you heard anything about the DDS repla

ER... Um... Could you re-phrase that as the Omni VII is " as good as a K3..." [It would make us Omni VII owners feel better...] ;-) -- Happy Trails. == Richards / K8JHR == ___________________________

They are both very decent.... I greatly prefer the Omni 7 audio over the K3. The K3 is a better with close in Dynamic range.. And if your looking for a sexy radio, just saying, that $10K Icom might b

Hi Glenn, Thank you for your explanation and continued efforts to keep a couple of my favorite radios in operation. While I'm now operating the OMNI-VII (with FLEX-1500 as the sub-rx) with DXLab Suit

I KNOW how you feel, Gary. I once sold an old guitar... it seemed like a good idea at the time, trading up to a better model; but, in cases such as these, after awhile, you feel like you sold your br
