This is an excellent point. Thank you for illustrating it. With a narrow filter, 100Hz resolution does not cut it in CW, although W4TV's proposed CWT "macro magic" will work around it, that is, if we could learn what the macro definitions would be with a programming manual. :)
I would like to know if this frequency resolution issue, along with the line cursor thickness and placement, the memory "permanence" issues and the Programming Manual Release are on the product roadmap schedule and will be addressed in future releases of firmware before I place a P3 on my family's Christmas Present list. I also agree with a previous poster that it would be "helpful" if the markers tallied the VFO selections and some of the params from the rig were displayed on the P3 screen. My station layout is identical to his, with the planned deployment of the P3 in the center, the computer monitor above it, the K3 to the right and the computer keyboard directly below it. Although I could rationalize the lack of a screen "repeater" of the K3 parameters because I can see those same parameters (filter settings, frequency, VFO selections) on the computer logger screen... The biggie for me is the resolution and line thickness/orientation issues. Im glad you guys are finding them ad are clearly defining them here. Thank you, brave pioneers, for geting there before me! You seem to wear the arrows in your back rather well. -lu-w4lt- Date: Thu, 12 Aug 2010 06:09:23 +0000 From: The Smiths <[email protected]> Subject: Re: [Elecraft] P3: a modest proposal for QSY To: <[email protected]>, Elecraft Reflector <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset="iso-8859-1" You're wrong Brett... No matter what you say the P3 doesn't automatically sync with the K3 to a 1Hz accuracy. The Center line on the P3 CAN be and usually is off by as much as 99Hz. No matter how you look at it, if you can move a Center position on the P3 with the select knob in the "CENTER" adjustment mode, and it doesn't change from the reading of 10.000.0 until you get up to 10.000.1 or down to 9.999.9 than logic tells you that SOMETHING is changing between those two positions which just happen to be 100Hz apart from each other. Conversely, if you can change the K3 from 10.000.099 down to 9.999.999 before the display on the P3 center line changes, than obviously the K3 and the P3 are not in sync to the Hz. Look, try this.. it's a very simple test. Take your rig, put it on 10.000.000 Now look at your P3, does it say 10.000.0. Let's say that it does (according to you it should), now, turn your VFO knob up until the P3 reads 10.000.1. Where is your K3 displaying? I'm sure it's not going to be 10.000.100. I know mine sure isn't, and that's after I set that center as close as possible. My rig displays 10.000.042. That's 58Hz off. Take your VFO move it down until the P3 says 9.999.9. What does your K3 display? Mine says 9.999.940, 60Hz Off. it's NOT accurate. We need the extra 2 digits in order to set the true Center of the P3 BEFORE doing a Ref-Cal. You just can't set the Ref-cal until you know the center has been set correctly. If you do, than you're going to have EVERYTHING out of wack by that much difference. Moving that Ref cal just confuses things more. I'm not over thinking it, on the contrary you're putting your head in the sand and pretending that the P3's center is following the K3 with 000Hz accuracy. When you center that marker and hit the QSY button you are going to move the CENTER of that carrier on the display as far or as close to the center that you just calibrated it to. You're just wrong.. I'm sorry. I don't know why Alan hasn't just come on here and said so... I've already seen 3 posts from him since we've been discussing this. The only people that this isn't important to are SSB guys that don't mind coming within 100Hz of the QSY freq. I don't know if you do CW, but I do, and when I land 80 hz away from someone with my 100 Hz filter on it makes a difference. The P3 was designed with SSB guys in mind, NOT cw guys. The accuracy of the center display, and the tremendous warm up drift all indicate it. I love my P3, and I'm having fun with it, but if Alan wants to make this friendly to the CW guys that requires more accuracy than the SSB guys use. He's going to have to 1 - re-write the manual on how to set up the Center, then the Ref-cal alignments, and then 2 - add the extra 2 digits to the center display freq. This is NO different that putting your K3 on 10.000.000 and setting up the Zero beat on your Config: Ref Cal. You just wouldn't do it that way if you didn't know that your K3 wasn't parked at exactly 10.000.000. You can disagree all you like. I've made my point, shown my facts, and I'm not going to argue any further on the reflector. Feel free to contact me off the reflector if you need me to explain further. That goes for Alan as well, I would love to talk with you and explain what's going on here if my explanation doesn't make sense to you. > From: [email protected] > Date: Wed, 11 Aug 2010 21:53:07 -0700 > Subject: Re: [Elecraft] P3: a modest proposal for QSY > To: [email protected] > > The P3 is centered on the K3 by default.
