Regarding the P3, I am a little confused about the cursor position. For VFO A, I understand this to be the Cyan colored U bracket like thing at the center bottom of the spectrum display.
Last night I was playing around with how this is affected by filter width and also passband shifting. Now, I believe that when I had the passband shift in the normal position with a 2.8 KHz filter width that my LSB signal showed the Cyan cursor being lined up right on the center frequency with the right side of the cursor border. But today, I am noticing that the cursor overlaps the center position a little bit. Still LSB, normal position on passband shift and also the same filter width of 2.8 KHz. So, this seems like different behavior and I am not sure which way is supposed to be the correct way. Can someone explain how this is supposed to be and how it might be affected by various controls. I am wondering if there is some control setting that might be different to show different behavior. Thanks for your help. 73, phil, K7PEH ______________________________________________________________ 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 |
There was an error in cursor position that affected certain digital
modes under certain conditions that has been fixed in beta version 00.29. But other than that the cursors should be accurately showing the actual filter bandwidth of the K3. The one exception to that is if you adjust the filter shift so that the bandwidth straddles the suppressed carrier frequency. In that case you don't actually hear anything (other than a little feed-through) on the other side of zero beat.

Strange, on mine VFO A is Cyan and VFO B is Pink. I don't have a white one.

Let's call Cyan "BLUE" most people will understand it better that way. Yes, VFO A is blue and VFO B is pink. They can each show you the filter width. Turn on "VFO B" in the menu to display the Pink width/shift "bracket" for VFO B, and HOLD the Marker button to show the Pink VFO B marker. You don't have to have both on at the same time. The white line is the CENTER line that runs straight up the middle of your P3. It splits right through the center of the K3's displayed Freq. at the top. > From: [hidden email] > Date: Sun, 15 Aug 2010 17:36:03 -0700 > CC: [hidden email] > Subject: Re: [Elecraft] P3 Cursor Position > > Strange, on mine VFO A is Cyan and VFO B is Pink.

Apparently my color vision is the issue here. For me VFO A is the same color as the baseline and VFO B is simply darker and slightly blue (which is why I assumed it was Cyan). Can you believe I used to do (color) camera set-up ... and could match them better than anyone else on the staff? 73, ...

While I do know the difference between cyan and blue, magenta and red,
my wife accuses me of having only 8 colors in my crayola box! She is one of those rare people who has a great color memory. She can look at a color, go to the DIY store and have a paint mixed to match what she saw at home. Everything is relative, and such skills vary. 73, Don W3FPR Ron D'Eau Claire wrote: > The colors are actually the RGB values for Cyan, as noted, and Magenta. > > People see them differently.

Got to play with N6XI's new P3 this last weekend. Pretty cool!. I did figure out that one of the little "U-channels" was VFO A and the other was B because turning the B knob moved it, and they get wider with wider filters. Unfortunately they look the same to me. In fact, all of it looks the same, I don't have any color vision. Notwithstanding, the P3 sure seemed usable to me. I did notice that the waterfall seemed to be of little use to me, and I don't know if that's because I'm not real fond of waterfalls and use the MMTTY spectrum display on RTTY, or because the P3 waterfall is color-coded somehow that's lost for me. Supporting myself in college at the end of the 50's/early 60's as an engineer at the local TV station, color TV was just showing up. I never turned the color monitor on so I never had to fix it because it never broke on my shift. All the rest I could do with the RGB scope, all of which were "Tektronix scope-color" traces. Most hams are male, most males max out at about 16 colors [Windows default], "peach" is a fruit, not a color if you're male, and no male knows what mauve is. 73, Fred K6DGW - Northern California Contest Club - CU in the 2010 Cal QSO Party 2-3 Oct 2010 - www.cqp.org ______________________________________________________________ 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 |

More multi-tasking than I can handle anymore, but I see your point. I probably won't be a P3 early-adopter, but then, I've never really been entranced with panadapters, even the old ones that weren't color-coded, except for green. > Yes, the waterfall is "color coded" and also varies in brightness or > intensity.

And no, I am not going to take Elecraft to court over ADA issues. I think I just don't like waterfalls on screens. The kind on rivers are great. Fortunately, I quickly found the switch that got rid of the WF and gave me a full-screen spectrum display, and it was a lot of fun, and impressive, to play with it. Keeping track of the two VFO's and filter BW in relation to the freq span and center freq was really cool. 73, Fred K6DGW - Northern California Contest Club - CU in the 2010 Cal QSO Party 2-3 Oct 2010 - www.cqp.org ______________________________________________________________ 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 |

I think I must be very fortunate, since I appear to be able to determine many more colours than 16.
Not having been able to build my P3 yet (waiting for the nuts!), I can't be sure, but it looks like the cursors are both U channels, what if one was an upside down U, would that help? 73 de M0XDF, K3 #174, P3 #108 -- Man is the best computer we can put aboard a spacecraft and the only one that can be mass produced with unskilled labour. -Wernher von Braun, rocket engineer (1912-1977) On 16 Aug 2010, at 22:00, Fred Jensen wrote: > Most hams are male, most > males max out at about 16 colors [Windows default], "peach" is a fruit, > not a color if you're male, and no male knows what mauve is. ______________________________________________________________ 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 |

Yep, they're both little square "U's." I didn't have any problem using them. Without the sub-rx, you always receive on whatever is in VFO A, so it's sort of moot, you're listening at the cursor on the center frequency, and if VFO B is not on the same frequency, it's the other cursor. I don't know if the U-channels swap colors when you do an A|B on the K3, but it doesn't matter. My K3 doesn't have the sub-rx, so I'm not familiar with its operation. Rick's K3 had the sub-rx and I'm not sure of the P3 cursor behavior when you do A|B in that case, I didn't try it. There was no manual at the operating position [it was at the West Coast CW Gathering in Reno Nevada and we were signing W6FOC/7 from the 17th floor of the Peppermill Hotel], however it can't have taken me more than 3 or 4 minutes to figure out the basics of the P3. The controls were very intuitive, I somehow knew that tapping DISPLAY would [eventually] get rid of the waterfall and fill the screen with the spectrum and it did. I'm sure there are a host of features I didn't get to, but I was using it on the air very quickly. It came across to me as highly consistent user-interface engineering, just like I expected from Aptos. The "16 colors, Windoze default" is a "sort of joke," although a lot of males seem to be less sensitive to closely related colors than females, and many who can name colors don't really care, one kind of green is as good as another :-) And in the "Think before you ask" department, people often ask me, "Well, just what colors can you see?" The answer of course is "All of them ... I just can't name them." 73, Fred K6DGW - Northern California Contest Club - CU in the 2010 Cal QSO Party 2-3 Oct 2010 - www.cqp.org ______________________________________________________________ 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 |
