I took the plunge myself - implemented the hardware mod and loaded v2 beta code. I was very pleased with the result. In reference to your notes below: 1. yes, I found that a contrast setting of 30 wo

I use cw on headphones *only* and have no such trouble with 2.054. Bob NW8L Was playing with the new beta release last night and noticed that, on cw and wearing headphones, after pressing the cw key

I use 500 Hz generally but find myself needing to drop lower when the going gets rough (weak sigs, low S/N), by whatever amount seems to bring the signal "out" the most. I really like the ability to

Ummm... Looking at the QST review of the Orion at (ARRL members only): http://www.arrl.org/members-only/prodrev/pdf/pr0401.pdf you'll see the cw keying waveform for external keying, on a time base of

Was an indicated setting of 5 "too low"? If so what is the person using external keying to do? Is this at root a firmware problem that in theory could be readily fixed or a hardware problem? Bob NW8L

Right, that was understood. The Orion review was the only evidence I've ever seen regarding it's keying characteristics, so that's why it was referenced. I'll have to take a scope home from work over

Good advice. Being a "show me" type, I took a digital scope home and looked at the indicated vs. measured rise times for cw keying in my Orion with firmware version 1.371. Scope: Tek TDS210 - 60 MHz,

I was interested in total rise time, so I measured from 0% to 100%, plus or minus 0.1 ms as best I could judge by eye, but the very distinct and uniform waveform made it pretty easy to do at 2.5 ms p

Of course you're right. It really should be measured like a pulse or square wave, in the standard way. After all it's between 10% and 90% where most of the "action" is anyway since this is a sinusoid

As for the Sharc DSP parts, they appear to be misidentified on the schematic. I believe they are AD21065L, really, right? I've never heard of an AD21D56L. If so, the 21065 ran at a maximum of 66 MHz,
