Some meter jitter is normal, but not 10%. It seems to be an artifact of the ADC - number crunch - DAC process. I wonder if v2 will address this. I did not see much if any "real" fluctuation in output

Of course they can't distribute v2 until the very last bug is exterminated. (Oh yeah, just like v 1.372!) Realistically, they must have a list of issues that have to be fixed and tested before releas

I think the reference is to the "New Coke" vs "Coke Classic" marketing disaster of some years ago. You may recall that Coke Classic was the winner. :-) I would be happy with "Orion I", but just calli

The main problem in software engineering is figuring out what is this program supposed to do, and how do we verify it? The Orion (only to pick one example) has an extremely complicated interface to t

We don't want beta testers to violate their non-disclosure agreements. They would have to sacrifice their first-borns, I think. (Of course, the O II is now visible "in the wild".) The S-meter rising

I agree that the semi-traditional RF Gain vs S-meter action has a value -- showing the AGC threshold and S-level above threshold. There is a place for this. There is also a place for a "true" signal

If you're listening to white noise only, you'd expect the audio power to be proportional to bandwidth (assuming flat audio response and no AGC). If you're listening to a CW note in the passband, the

The stock filters have always been FB for me, performing way beyond my previous setup, but I'm not an agressive op. The extra filters add nothing unless you have bad out of band QRM. If the question

Yes, I could have been clearer. There are different "bands" or passbands to consider. Say you are working CW with the stock 1 kHz roofing filter and you have the DSP BW set to < 300 Hz (assume no PBT

A quick check is to tune in a steady S9 carrier and then switch in 6, 12, and 18 dB attenuation. That should give you S8, S7, S6, respectively. I've found pretty fair agreement on my (classic) Orion.

They are an interesting toy for $10. Not the best headphones by a long shot, but they could be effective if you have bothersome fan noise. I looked up the Bose headsets for pilots -- a cool $995 prod

That would be the image of the 2nd IF = 450 kHz. TT's clever phrase is "specifications apply > 1.8 MHz". I.e., all bets are off below 1.8. The Rx is insensitive, and as you see, image rejection is po

It is unclear to me that the same binaries will run on O II as on O I. The inner workings of the control system aren't identical. Possibly the same source code handles both rigs, which can be compile

Jim, I'm surprised your grounds are equal "to the microvolt". To me, that indicates that no current is flowing in either, not even reactive, or else they really are bonded together in some way. A pra
