MCU 4.51
Locked
 
|
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. I run the threshold at 14 and the AGC SLP is set to 000. The Noise Blanker is improved. I was able to get rid of s7 line noise, and no distortion in the audio of the received signal. NB settings are dsp T2-4, and the IF is NAR 4. So, the noise is being eliminatd with low setting of the NB. I suppose the real test will be when I hear s9 plus line noise which I frequently get here. AF Gain is set to LO in the config menu and have plenty of nice and crisp audio. I am listening to SSB on 80 meters now and have the RF gain set to about 9:00 and AF gain about 12 oclock. Just lots of gain and audio. I think 4.51 is ready to go BETA. What do others who are using 4.51 think?

I just got it tonight. I have not had much chance to compare but the NB
in 4.50 is much better! A curious unexpected side effect!

I have also missed the 4.51, and even the 4.50 release. The only beta

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.

If the adjustment allows half steps, e.g. 0, 0.5, 1, ... 8.5, 9;
then you would have about as many steps and still have some vague relation to S units.

Gregg,
It was sent to the K3 Firmware Field Test group and to those others who requested it from Wayne. It is not beta material yet - You might call it an evaluation. There were some problems with the first pass of that code level 4.49, but it got changed twice and is now 4.51. If you understand what is involved in testing code of that level and want to try it, a note to Wayne will allow you to join the "fun" - it will come to you as a zip file. Or you can wait until it (or some subsequent number goes to beta and is posted to the website) If you don't remember, the beta firmware must be manually downloaded and saved in some folder on your computer. Then you te0ll K3 Utility where to find it. The semi-automatic "get new files from Elecraft" only works with released firmware, not beta. 73, Don W3FPR On 5/12/2012 4:49 PM, Gregg W6IZT wrote: > It has been a while since I downloaded a beta release.

We will have 4.51 available as a beta version on the website later tonight.

Took the FW4.51 for a spin at PI4D in the CQ-M on 20m in SSB and CW
yesterday afternoon. AGC THR on 12, SLP on 10. Smooth operation, NB performed OK for the key clicks from a nearby freq. (NB is DSP 2-3 and IF MED3) Was it better than FW4.48? Not sure, but I like it that the threshold can be moved upward a bit, it was always on 8 before. I did not encounter big pile-ups. When I had two stations of the same strength on exact the same freq it was still hard copy to pick only one out. 73 Arie PA3A ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

For taking care of key clicks, NB LEVEL set to DSP t1-7 or t2-7 and IF
*OFF* is best. I got excellent results with the milder t1-7 in 4.51. IF ON is traditional IF blanking with all the traditional artifacts. Kept on the K3 because it's still best for some kinds of noise. Traditional IF blanking in anyone's RX still will create lots of artifacts in a crowded contest band with lots of strong signals, including the K3. 73, Guy.

I found on what I was listening to, that turning off the IF blanking
cleaned it up and t1-7 or t2-7 was incredible for key clicks. The other thing was that I always carefully minimize signal input on lower bands with ATT/ /PRE/RFgain at only high enough to bring up band noise to moderate in the passband. Additionally I used the 8 pole CW filters, and set their offset so that the -30 dB points were equal either side when the DSP and the true filter bandwidth matched (450 and 350). The 350 in particular turns the clicks into spikes, which the K3 and NB handle extremely well. I have seen key clicks reduced 7 or 8 S units in some cases. And this was on 40m on the big 5 element quad on a 58 meter catenary fixed on Europe. Some REALLY loud Eu signals on that antenna. Yes, I too can get NB artifacts with extremely loud in-band signals. But the biggie I care about is killing the key clicks. That's worth the price of the radio all by itself. 73 & GL, Guy On Sun, May 13, 2012 at 3:53 PM, Arie Kleingeld PA3A <[hidden email]> wrote: > Guy, > > Well, both NBs create artifacts if pushed to hard. > I have not encountered any problems when using this config (DSP x-3 and IF > med-3).
