They had pc's in 1958 ? Interesting. I was still using mainframes and terminals in 72....shows how much I missed.

I operate PSK 31 and RTTY almost exclusively. Just a tiny bit of SSB, no CW any more. But I'd like to try digital voice. Is anyone using it ? Comments ? Hardware ? How's it work with Ten Tec radios ?

It will pass code if you ONLY wire the sub-panel to supply 240 VAC and NOT 120. That is, one hot lead is in the black lead. The other hot lead is in the white wire, which is taped conspicuously at bo

What I said was, specifically, that you MAY add a ground rod at a secondary panel. But - it is not sufficient to meet code. In other words, you still need a ground wire back to the main box ALSO. THa

The problem with using software and/or DSP Chips is that no one, except for the military, can afford DSP chips that can operate on signals up in the megahertz range. Thus, all DSP work in amateur rig

Yes - and this would help to add clarity to the discussion, since many people still seem not to know that the card is in fact being used as part of a DSP processing system in this arrangement.

Not to belabor the point excessively, but Mike is right. The Air-Pax units are specified for use with Ten Tec rigs specifically because they are so fast. Have saved my rig and many other's. Use them

I understand the intuition that a fuse ought to be fast. It seems simple, right ? No moving parts. However..... It is a thermodynamic device. It requires that the metal in the fuse be heated for a pe

FWIW.....not ALL DSP just narrows bandwidth. The way it worked when I used to work with audio DSP systems in a previous life (and the IF of the Orion is at an audio frequency) is that each sample of

I just meant that 15 kHz is a frequency in the audio range. I know it is used as an IF frequency in the Orion. The point was that the frequency is very low....low enough that DSP chips can process th

Grant, no, it isn't the same deal. In the final analysis, it does not have the same effect. Correlation based DSP computer algorithms are much more effective at noise reduction than are band pass fil

That's right Duane, that is exactly what you get, highly correlated signal plus noise in the band pass. You are right, that is why the other approach can be in fact better, given that other related f
