Mark, Unless you're constantly running in a multi-multi contest station, or live nearby one, you don't need this mod. The VI+ is already an awesome performer. Wish I could have kept mine when I bough

Try unplugging the TV's. Many of them have power supplies that are noisy, and you need the PS on to keep the remote control circuitry alive... I returned a Zenith several years ago that had LOUD carr

I think the purpose is to allow better readability during contesting where you must run with filters open (if you're running on a frequency). The idea is that any help you can get in separating signa

Simple to check out -- turn off the computer and pull the plug to all the computer gear and see what happens. Besides, Jim, you're in Texas - it's NEVER quiet on 80m in Texas. You need beverages or o

Just a quick repeat of my comment earlier - you can't just turn off the PC and the monitor. You must remove all AC and backup DC power from them. I had a monitor that spewed noisy carriers all over t

I don't think that's the point - the firmware is a different level of code than Carl's code, and has many more limitations including those of time to develop, test, etc,. in order to get the rig to m

Not so. My VI+, purchased new in Nov '97 did not have TCXO. It was at least a couple of years later that it was incorporated, if my memory is correct. 73, Duane Duane Calvin, AC5AA Austin, Texas

This could happen if your power is right on the edge of 1000W and a very small variation in that power would drop it below the value needed to light that one LED. I don't know the circuitry, but it c

The RF signal handling on strong signals definitely has issues in the new update. Last night, K5NA on 160m measured S9+35 on the S meter, and the tone was completely missing on his CW signal - I had

No, I didn't think to try that, Toby. I usually go for the attenuators first since they're fast and easy. If I catch them on again this evening before the end of the contest, I'll try what you sugges

This is NOT a recommended fix on the Orion. Shield pin connector is actually audio return, and not ground on the Orion, so tying it to ground is not recommended. Check the archives - there was a long

DO NOT connect pin 2 to chassis ground on the Orion. I posted earlier this week about this! It does not work on the Orion because now you have tied one side of a differential audio input to chassis g

Turning on the noise blanker causes the dynamic range of the RX to suffer substantially. That's why you'll get garbage from nearby stations when you turn it on. The reason CW tones sound raspy is bec

As much as I like the Centurion, go for the Titan III. Why? The 3-500Z's put out by RF Parts and used in the Centurion just aren't as stout as the GU-400B's used in a number of amps today. You're rig
