241. Re: [TenTec] Whats UP? Orion II (score: 1)

I think you would find 2.034 a little bit better than 2.032. For one thing, the AM monitor will work in 2.034, and the speech processor is better. The bigger problems are still awaiting a fix, like t

Something must have gone wrong in the upload since the AGC sounds horrible on 2.037J! Even at very slow recovery settings (down to 2 dB/sec) the s-meter drops like a rock, then hits a point where it

I reloaded 2.037J and did a master reset. I still noticed the AGC is way fast compared to earlier versions, and may be the source of reports of 'raspiness' in the receive audio. I hear it too, but wa

I'm listening to the WAE contest this morning on 20 meters, and with the AGC setting tweaks it sounds much better than yesterday. Maybe it was just conditions at the time. With the slight bit of hang

My guess about the faster decay on O2 with 2.037J is that short pulses cause a fast attack, followed by a fast release. On very strong SSB signals, this is most noticeable since the S-meter moves dow

This was the fix we were waiting for to get the Speech Processor working right. I did some tests using an old Collins 302C-3 watt meter which has relatively slow meter ballistics. I yanked the bass o

I checked mine again and it seems normal, and much improved over the old one. Much cleaner sound. One thing I did notice is that the recorder appears to differ from previous versions in that it recor

I noticed something similar in 2.037j and I believe it has to do with AGC time constants. Adding a small amount of 'hang' to each of the AGC settings fixed the problem. Ron N6AHA ____________________

Some time back, I complained that the Orion 2 had distorted AM receive characteristics. I had tried using very slow AGC release time, but it still sounded distorted. When I loaded 2.037j, I initially

This may be the problem we are seeing in 2.037j with the new AGC scheme. I found that using the slowest recovery times for each AGC setting and adding some 'hang' fixed it. Try .21 s for slow, .17 fo

If you are using Heil headphones that have the phase switch, try running the phones out of phase. If you don't have those, try reversing the phase of one of the phones by making a jumper with a switc

I used it on 75 meters the night before last and got good reports but I did notice the "upward modulation" effect you saw. Looking at sine wave on a regular oscilloscope, it looked like standard 100%

I think there is an adjustment that controls the output level that may need tweaking, and it may effect the AM carrier. It might be worth a call to TT to ask about that. Also, if you're only getting

I agree that something else must be going on. Analog meter ballistics might effect what you see under SSB or CW signals, but I ran my test with a signal generator using fixed levels and found the dis
