Sounds to me like another example of something that should in reality be a user settable choice in the setup menu somewhere. It really shouldn't have to be just one way *or* the other, this is a soft
I've thought about variations of this idea and even done some basic RX experiments with it. My most serious experiments to date using this basic idea were over a year ago using a Corsair II as the tu
Note that posting was before I had used the Time Machine board. Even so the results were almost the same whether I used the SDR-1000 as the IF or the Time Machine board. So I have very little doubt t
As far as I know the early ##-## S/N format is simply sequential. I'm not aware of any public listing that equates specific S/N's to dates either. So then it's a matter of looking inside the radio it
Just sitting here restraining my fingers from typing a whole lot more ;). Much of this excellent post does sound kinda familar though...:)... Duane N9DG ______________________________________________
<snip> Just to clarify: The upcoming aditional RX's for SDR-1000 will be software only implementations and be identical in performance to the 1st. No new or additional hardware will be required. So t
I don't have a Omni C here but those symptoms sound identical to what happens with a Corsair when the VFO In/Out jumper on the radio's back panel is either missing or is intermittent. Duane N9DG ____
Absolutely. Hopefully the Pegasus II will be similar to the SDR-1000 :). No doubt that it's the first of a truly new breed. Since it is so new it is roughly comparable to what the Triton I, SS200, SB
I don't have an Omni D but do have a 580 Delta. One thing that the 580 can do that the Omni D (non series C) can't is 17M. Though you can run the Omni D series C on 17M you really don't want to. The
RE LO noise measurements - Note that the Sherwood measurements are not very consistent for the spacing used to measure the LO phase noise: Orion (II) 10kHz Corsair 4kHz Omni VI+ 20kHz It's really too
I will stick by my wish to see it standardized at something under 5kHz, much for the same reason as wide spaced IMD performance in the IMD dimension. I highly doubt that is the case. I suspect that t
Perhaps a better way to think about it IF scheme wise is that the Corsair is like the Omni A/D/C series but has the 6.3MHz IF (started with the 580 Delta) for PBT and narrow BW IF filtering. Once out
Sort of. No. Duane N9DG __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com ________________________

Not sure where the notion that a 2 dB NF is sufficient for 2M SSB/CW work comes from. I suspect though that it is a figure that has persisted for years in ARRL Handbooks. I would argue that a NF in t
Actually I'd be wondering which ones of the existing big 4 will still be here 5 to 10 years from now. I really do get the sense that there is another major "changing of the guard" for radio manufactu
Actually I can believe Barry's claim for the 2.7 kHz. I have a few Corsairs (2 are II's) and everytime I tap into the IF chain after the 9 MHZ filter using either SDR-1000 or the Time Machine board I
I'm 98% sure in the 455 kHz IF. The IF scheme from what I can tell is very close to the Pegasus/Jupiter with 45 MHz 1st IF and ~455 kHz second IF. Putting the improved filtering in those two spots wi
More wild speculation below: My guesses are: 1) Because they feel it will equal or exceed the Omni VI in performance. 2) It will be a "step up" from the Jupiter, the Jupiter will remain in the produc
FWIW I fairly regularly get into the top 10 for the Single Op Low Power category for the various ARRL VHF contests. And for multipliers I typically finish within the top 5 for the 144-432 MHz bands.
