- My Orion with 1.372 works great until receiver (DSP) is overdriven by strong signal- about S9 plus 30dB. There are many of those signals in the contest. And yes I have quiet location with "quiet ante

- Yes, same here, happens usually on the Low Bands. But there you can add 6 or 12 dB of attenuation and won't loose anything... the noise level at nights is high anyway... 73 de Chris DL4YAO --Urspr&uu

- I work quite a bit of topband with my Orion and can't say that I experience this problem. Have you tried turning down the RF Gain control? 73, Barry N1EU _____________________________________________

- I concur with Barry, and I run my gain no higher than 90. I see absolutely no degradation of signal levels, and it helps keep atmospheric and other noise down, especially on the low bands. I used my

- I thought the selectivity was outstanding during the test. I was hearing weak sigs on 40M right next to S-9+ sigs. OTOH, the NR consistently raises the noise level. It's as if the RF gain is being in

- Why use the NR at all. Especially in a contest? Seems to me that that much DSP is detrimental to the overall performance in a tight packed band. Next time, try running it with the rf gain turned back

- For weak signals, ( and most other applications ) I am not using the Noise Reduction or Noise blanker at all, Seems like the automation always does something I don't want. All is manual controls of A

- Somewhere, and I don't recall where, there is a writup on this or perhaps it was just an email from Scott on the tentec list. When NR is turned on, AGC THRESHOLD is reduced. That is what accounts for

- Thanks Tim, Grant, Rich and Larry. Well, when I engage the NR I can turn the RF gain down to 1 and still things sound noisy. I typically run my RF gain (w/o NR) at 55 to 70 on 40M. AS Tim describes b
