Is the behavior the same on the Cosair 1? This is an interesting (if odd) result. Especially as it is an important issue for comparing IMD DR and other numbers (which is what I'm doing). Sherwood (et
It could be just a configuration issue. Or it could be a kernel regression ... <http://blog.aa6e.net/2007/03/among-kernel-developers.html> My new Dell laptop has only USB ports, so I bought a Keyspan
Interesting tip. In the Omni series C (TT 546 Series C) I not that design was rather cobbled together to add the WARC bands. They had decided on low side LO so they used that for 17m too. So 4MHz cry
Of course. The mixing will invert the sideband even though the tuning direction isn't changed. Better than lots of RF in the IF strip. At least they wised up on the next design. Ah, the perils of put
OT but too much to resist LI2B operated by LA7Y <http://www.arrl.org/news/features/2003/03/05/1/?nc=1> <http://www.arrl.org/news/features/2003/03/05/1/sibebar.html> <http://www.infoage.org/p-86Kontik
The other thing to consider is good old fashioned cross-over distortion at low audio levels. This seems to be the reason TT suggested a pad (of a couple of hundered ohms) in series with the headphone
Ten Tec Argon I rather like the sound of that. Perhaps a future QRP rig name. You heard it on the Ten Tec list first :-) Argon? whats a Argon? there is a Argo (Scout's baby sister) there is a argonau
Are you sure you actually need to modify the ring mixer diodes? When I got around to looking at one of my (now two) 525D's I noticed there are a few differences even in the same model run. I've been
Once you have two you can compare them. :-) My 525D serial 01611 has a front panel (below the meter) that looks like the analogue Argosy. The name plate says "TenTec Argosy". Like this: <http://www.r
Looking for the 8 pole 2.4kHzwide 9.015MHz #220 filter for an Argosy 525D. Reply to me off the list. -- N7WIM / G8UDP Kevin Purcell kevinpurcell@pobox.com
Another difference between the 525D and the 525 is the low/high power switching. In the analogue 525 the switch takes the PA out of the system -- the driver drives to LP filters. In the digital 525 t
My point was that you aren't going to get a better match from 4 HP separate diodes (which may or may not come from the same batch) than the integrated ring so that mod is not worthwhile Do you agree?
Is it intelligible (but just pitch shifted) or unintelligible? Does the pitch change with USB or LSB on the same band? I would guess it's one of: HF getting into the audio; SSB 9MHz leakage in the RF
This is a very good point. I think it's mentioned in the manual too! On my Argosy in a high RF environment (multiple TV TXs within 1 mile) you can hear the 60Hz frame buzz with volume just off zero w
