I found Carl's original Message from last year that addresses the addition of his RX-340 4 kHz roofing filter. Pay particular attention to the last paragraph. -Paul, W9AC
It's pretty hard to beat the Ten Tec 705 microphone for good fidelity and simplicity. If you want to step up to something of an even better quality, you may want to consider their new Studio One mic
I generally stay far away from switching power supplies: My main shack supply is centered around an Astron RS-35 linear supply and power is distributed to many devices via a RigRunner DC distributio
Yes. In many of my Ten Tec's, I have bypassed the internal "Ext. T/R" relay with a 2N5551 NPN transistor for fast, completely solid-state amplifier switching with non-Ten Tec amps. It's important to
It's weird anyway and the harmonic distortion produced by the crystal element is very high. This is not necessarily a bad thing as the distortion component can oftentimes be used to one's advantage.
With so many similar complaints on the Argo V, I had to take a look at the schematic to investigate... Actually, Ten Tec did a nice job in the mic pre-amp design. I suspect the nominal output of the
Be cautioned that unless your Ameritron AL-1200 has hot-switching protection circuitry, the mod as suggested above will likely cause hot-switching at the leading edge of transmission. You mentioned
This is worth repeating...Ten-Tec's TX OUT/TX EN should only be used with amps that support such a key loop structure. Grant found out the hard way. Unless one is using an amp which uses a send and r
I stand corrected then...glad to see that the AL-1200/QSK has a separate send and return key line. I was assuming you had used the mod on the Alpha page verbatim. -Paul, W9AC
Rebuttal: First, I hold a J.D. law degree, a fully accredited MBA, and a double-baccalaureate in Electrical Engineering and Computer Science. Big deal and so what? In my opinion, it's Ten-Tec's prer

And the same is true for Yaesu, ICOM and Kenwood, and nearly every other amateur radio manufacturer....only we do not know of their missed production dates, because we are deliberately kept in the d
There's a big difference. Herb Johnson at Atlas deposited the purchaser's cash into his bank account at the point of order. Conversely, Ten Tec, is holding on to your payment *information*; they are
Actually, the filter helps to diminish the effect of the chirp in the Omni Six/+. You're absolutely correct in that the Omni Six's CW carrier is placed dangerously close to the 2.4K filter skirt. Th
I have a great Triton IV that I am reluctantly letting go in anticipation of purchasing an Argo V. Excellent cosmetically and operationally...9 on a 1-10 scale. PTO is smooth and everything works as
I can attest that Steve's mod can more than keep up with anyone's keying. It's essentially the same sidetone oscillator circuit as used in several other TT rigs like the Paragon II and Omni 6 and oth
FYI - This from the Argo V Mail Reflector. The epilogue is that wiring the Argo's two whisper fans electrically *in series* at the Molex power connector provide ample cooling and much less fan noise.
Agreed. This never used to be this way. What happened? Had the list reply logic not changed, poor 'ole George would still be with us today. Is the list administrator listening? Please, please please.
Although Ten-Tec specs the key line voltage at low DC voltage for warranty purposes, the TO-220 style keying transistor in the Pegasus is actually speced to handle well over 100VDC, but I don't recal
