I have to confess that until a few weeks ago I had been thinking that if I ever got 3 or 4K$ to spend on another rig I'd probably give one of the JA rigs a try. I had been looking at the ProII and the 1000D. The reason is that I'd been with Ten Tec for so long I figured that if I wanted to intelligently discuss the competition I'd have to give one of them a try first. Also, I was curious about the way the rest of the ham world lives. I have never owned a hf JA rig. It's always been Hallicrafters, homebrew, and Ten Tec with a Knight Kit in there somewhere. Then, I finally got around to reading all the material I had accumulated on the Jupiter, Orion, SDRs, and DSP. Boy, am I glad I didn't buy anything first. Here's the impression I came away with:

I think we are going through a watershed period in HF transceiver development and it's exciting to think about where it all might lead. I think that it won't be long before everything designed and marketed before 1997 or 1998 will be viewed as obsolete. We took our baby steps with this technology in the 1990s. It reminds me of when color tv first began to come out but it wasn't very good. You had to adjust the tint and color all the time, the CRTs were round, the TVs were these pieces of furniture that weighed a ton and everything bled colors and looked like a bad day on drugs. But 10 years later almost no one had a black and white tv because the technology had vastly improved. My Omni is, in DSP terms, like an early color TV. And with the programmable Jupiter and now the Orion, it is starting to get really good.

What's coming up? I think transceivers are going to keep sounding more like computers. Instead of DC to light band coverage at the tops of magazine ads, we'll see clock speed and no./size of processors being hyped. In the way Dell, Compaq, and others make a kind of generic pc box, perhaps transceiver mfrs. will all make a few standard transceivers at different price points with their identities associated more with software than anything else. You might even buy a Kenwood box for example, and load it with Ten Tec software. Or maybe software development will go the open source route entirely. How would you like the option for a dual trace scope, or SSTV on your front panel screen included in your software along with today's spectrum display? It might be possible someday in a completely programmable radio.

I'm not trying to put down all the analog gear out there (which is about 90% of everything in service) and I fully intend to hang on to my Corsair II until it's in my estate sale, but I'm also looking forward to what's coming up while what I have eases gracefully into vintage boatanchorhood. I'm pretty sure what my next rig is going to be unless the JAs get busy soon. Anyone else have any predictions? Technologically, reports of our death are greatly exaggerated.

73,
