I can't really tell if there is an improvement due to the new log algorithms but I really like the extended Threshold adjustment range. I typically listen to CW on a wide filter setting and used to have my AGC at Threshold 8 and Slope 0. Now I have Threshold at 15 and thinking I should flatten the Slope at this point; currently set at 5, but I'm still playing around with it. Possibly could go even flatter.
I don't use the NB enough to notice a difference. I was already quite happy with the NB action on CW. It has always worked when I needed it. Possible minor feature suggestion: I was thinking that it would be convenient to have the Threshold numbers coorespond directly to the meter S-units (i.e., a threshold adjustment range of 0 to 9). But I'm uncertain if I'd want to give up the finer granularity of the current 0-20 range for the ability to directly set the AGC point according to the s-meter. I guess I'd have to try it both ways. Anyhow, I really like the improvements. I always thought it was a major limitation to only be able to set the AGC point up to about S-4 or so. 73, Drew AF2Z On Fri, 11 May 2012 20:55:44 -0700, Toby W4CAK wrote: >I don't know what others have been experiencing using the new 4.51 firmware >version, but I really think it is an improvement. > >I have been listening to pileups tonight on 20 meters and cannot discern any >mushy weak cw signals, signals are crisp and easily readable. > >Maybe I need bigger pileups to get a better handle on this aspect, or certain >band conditions.
