Doug Smith wrote up a bunch of this at the beginning (http://www.doug-smith.net/downloads.htm), but there hasn't; /archives//html/TenTec/2006-02/msg01262.html (9,843 bytes)

My antennas are resonant, too, but I've been able to stretch them. The 80 M dipole does well on 30 M with the AT, and I even manage the occasional contact on 160 us; /archives//html/TenTec/2006-01/msg00021.html (8,077 bytes)

It was kind of weird running the Orion and talking to a fellow running a Heathkit DX60. Talk about a distinctive signal!

Maybe we need an "echo club" or a "worked all echoes" award? hi It seemed that a lot of people (most?) didn't bother to call CQ SKN.

[TenTec] Radio Science + QSK = Radar (score: 1): Author: "Martin, AA6E" <martin.ewing@gmail.com>; Date: Mon, 2 Jan 2006 13:20:32 -0500; When operating QSK at 15-20 wpm, I am running into echoes of my transmissions. These occur on certain azimuth bearings at certain times of day, most often to the SE, which is over water until hitting; /archives//html/TenTec/2006-01/msg00047.html (9,193 bytes)

When you hear a clear echo, the response is fairly coherent (with a; /archives//html/TenTec/2006-01/msg00054.html (10,682 bytes)

(It's pretty distracting to hear echoes while sending.) I never heard it with my old non-QSK rig with a slow R/T relay. I don't; /archives//html/TenTec/2006-01/msg00089.html (11,343 bytes)

The Orion works fine, except that there is ~28 msec of dead time between end of Tx and beginning of Rx. This is w; /archives//html/TenTec/2006-01/msg00144.html (7,392 bytes)

If you use the monitor, it's very easy to get audio feedback & oscillation. On the other hand, your average power shoots up to ne; /archives//html/TenTec/2006-01/msg00315.html (9,273 bytes)

I used to think all the Orion (1) frequencies were derived from the TCXO. I've had reasonable luck tweaking the oscillator for better accuracy, as have others.

But I'd like to see a zero beat display - e.g., Lissajous plot of signal vs SPOT or even better, a Fourier transform view that shows phase & freq centered on 0 Hz.

It's 24 cents a throw, if you can handle it. (It's cheaper still to work DX and use the QSL bureau.)
