I used my Omni V.9 extensively with Writelog using a standard serial cable. Only pins 2, 3, and common on a DB9 are needed for computer control. I used pin 4 and common to send CW. Worked VERY well.

I bought a 599zx to use with my Omni V. I also tried it with a TS850. I was generally disappointed with the result with both radios, and sold it. My observations are pretty much in line with Jerry's.

Don't blame environmentalists -- it's lousy circuit design. This doesn't sound like a line filtering issue, but it DOES sound like possibly improper connections of neutral and the power system green

Right. Clarification for those who don't do this every day. There's a big screw in a breaker panel when you buy it that bonds neutral to the frame of the panel, and the green wires (and physical grou

NO! It all comes down to how the 240V appliance uses power. Certainly 240V for the heating element, so that's two hots and a ground. It's easy to make a motor that runs on 240V, so no neutral would b

The problem is that such a connection DEGRADES SAFETY. That's why the code was changed! AND such a connection creates a magnetic field that can cause hum in electronic systems. 73, Jim K9YC _________

That's pretty much true of all modern amps and modern transceivers. You adjust the power output control of your transceiver (in this case, the Omni VI) to get the "right" power out of your amp. With

It is neither a rumor nor outdated. It is POSSIBLE to build quiet switchers, but it costs more, so 99.9% of all switchers are nasty noise generators. 73, Jim Brown K9YC ______________________________
