The operative word here is "reasonable." Al, I don't disagree with your statement in the least, but for most of us, securing a vector signal analyzer simply isn't an option for our measurements. -Pau
Since Ten-Tec has led the way in the use of aluminum during its entire products' history, I suggest something completely radical for the Orion... How about an anodized front panel with a choice of an
Nice work George. It appears that the 10 Hz change is indeed detectable with the waterfall display. Now, we just need to apply it to a strong signal with microchirp. Looks like the resolution with Mi
I'm not sure of the methodology, but I recall a graph from a Navy study in which keyed envelope shape rise/decay was plotted against minimum discernable signal strength. Another graph depicted CW sp
Agreed 100%. With narrow filters, I notice no difference regardless of rise/fall time. The filtering rounds the edges and extends the rise/fall time. However, under MDS conditions, I almost always u
I own both. You can see my RX-340 and Omni Six Plus at: http://www.qrz.com/database?callsign=w9ac The RX-340 is superior to the Omni Six on the ham bands...period. The RX-340 is seemingly impossible
The CW speed has no bearing on the Omni's CW note. Go back and re-read the reflector archives in 1997 and 1998 for a complete discussion of the issue. Thanks. -Paul, W9AC
I thought that in the '80s, Ten-Tec had quite a few offerings happening simultaneously or very close apart. I'm thinking of the Delta, Corsairs, Omni D-B/C...Argo 505/509/515, Argosy, C21, C22, Trit
You can't. In fact, I know of no electronic instrument capable of reasonably detecting it. Sometimes the ear is the best judge. The keyed waveform oscilloscope display has no association with frequen
Some good points Jerry. Provided that the audio spectrum analyzer is fast and capable of displaying resolution of less than 10 Hz, it may be of some use. Regarding the use of an audio oscillator agai
Correct to the extent that CW bandwidth may be minimized. I don't necessarily agree with Tom's view that the "correct" CW waveform is one in which the transmitted bandwidth is minimized by extending
Some TR7s and C-Lines sound exceptionally good. I still recall the sound of Paul, K4CA who used a T4XC modified for QSK. I once looked at his waveform to see what was happening and it was a mirror im
Gosh, I don't know about that Steve. I recall a guy in Lexington, KY who came up with a great sine-wave sidetone mod for the Tritons and Omnis. It sounds so good on my Triton that I consider it a "mu
If you go to the Topband archives on contesting.com, there's been a very good discussion running recently concerning key clicks and as you mention Steve, the ability to hear what's always been there
The strangest thing just happened to me tonight while I was operating my Pegasus.... As I was cruising down the 20-meter band, I decided to put the mouse cursor over the tuning slider. As I did, I no
The Omni Six has already celebrated its 10th birthday and, amazingly, it's still in production. With few exceptions, what other transceiver can claim a successful ten-year production history? I am ho
Teamed-up with the N4PY software, the RX-340 is substantially better than the Omni Six in both features and performance, and with a $4K price tag...it should. For those interested, I have a review o
Jim, Based on your description of the operation of the QSK-5, I am guessing that the following interconnections "should" work: QSK-5 OMNI 6 AUX <==> TX EN KEY 2 <==> TX OUT It would appear that KEY 1
I went to the Ameritron web site to download the QSK-5 manual. Instead, a model QSK-5PC is shown and apparently the connection choices are much different. Oh well.... -Paul
