I use them often as well, but probably would prefer I to be fixed rather than tweakable.

I don't like the presets floating every time I make a change. They are not
presets, they are resets and I never know what might result from pushing the button because I can't remember what width was used the last time I switched it. I would much rather have a wide preset and a narrow preset that I can quickly and easily get to. Even better if I get to pick what that might be. I would know that if I hit the preset I in CW mode it will be a narrow 500hz and preset II will be a wide 1.5kHz. In SSB mode I might chose a preset I as narrow 1.6kHz with the passband slewed to increase intelligibility and preset II as wide 2.1khz with the passband centered. The NORM function is nice but it is fixed too narrow (400hz) in CW mode and too wide (2.8kHz) in SSB. Maybe NORM should be used just to center the passband and then the user could set the two presets for the desired widths and passband offset. k4ia "Buck" K3 #101 Fredericksburg, VA **************Ideas to please picky eaters.

Egads, the presets work this way. (Don't have my K3 yet).
I was really mislead by the manual description then. Then call the "roulette sets" in the manual. Not very useful if they are not fixed. I much prefer to know what I'm getting. The ability to switch between two known settings is useful. I can only see switching to an unknown one can loose time and a QSO in contests. de Brian/K3KO <quote author="Phil & Debbie Salas"> "Before we make any changes, I'd like to know: - if you use presets at all - if you like the new proposal better (making them fixed)" I use the presets all the time.

Wayne,
I am mainly a sideband operator. I like and use the presets. I have preset "1" set for narrow filter and shifted for best audio. Preset "2" is set for a wider filter for rag chewing. I agree with the points made by WB6MND and so would also prefer fixed presets. When the QRM starts, you can quickly change to preset "1". It saves a bit of fiddling with the width and shift controls. I am eagerly awaiting the firmware change that will shift the filter centre (on SSB) as it is narrowed. This will make the filter adjustment on SSB way more convenient. The large change in audio level when switching the Noise reduction off (SSB mode) is sometimes deafening. I believe this is under review. 73 Tony Fegan VE3QF K3 #137 K2 #490 (sold to a good friend today.

Tony,
To reduce the width on SSB, try just using Hi Cut instead of the width and shift controls. Normally when reducing the SSB filter width, the low end should be near 300 Hz (the K3 uses 250 by default). Keeping the low frequency corner of the SSB filter fixed at 350 to 300 Hz preserves intelligibility as the highs are reduced with the Hi Cut control - try it, you might like it better than fussing with the Width and Shift controls - I do it that way all the time, no need to adjust the low end unless the filter is VERY narrow (less than 1400 Hz = Hi Cut at 1650 Hz) 73, Don W3FPR Tony Fegan VE3QF wrote: > I am eagerly awaiting the firmware change that will shift the > filter centre (on SSB) as it is narrowed.

I'm sure Don has given this advice before, because on someone's advice here
some time ago, I started doing it this way and find I have much better results.

K3 Narrowing the filters on SSB
|
|
In reply to this post by Don Wilhelm-4
Hi Don,
Thanks for the reply. I do use the Hi-Cut for reducing from 2.7KHz to about 1.8KHz with no problem. When you go much narrower the intelligence is improved by raising the low cut frequency (especially with low side QRM). Now you have to juggle with the Lo and Hi-Cut to squeeze out the maximum intelligence. I would have preferred positive detent style encoders for these controls. A firmware change (SSB) to move the filter centre frequency down as the "Width" control is reduced would mean this can be accomplished with one knob. I understand this is being considered. The present Lo-Cut step is a little coarse. I would prefer a step size of 50Hz. This is important when you get close to 500Hz on very narrow bandwidths. A low-Cut of 450Hz is still copyable but at 500Hz there is a big reduction in intelligibility. Of course, voice characteristics and your own ears make a big difference too. It is possible to shift the steps by 50Hz but you have to move the width control by 100Hz to do it. Part of my problem is that I have poor eyesight and not much feeling in the tips of my fingers. When I make an adjustment, the display has gone back to VFO before I can read it...... The processor between my ears is an old model with not much memory...... A while back, I used to have senior moments but not any more...... Now I have non-senior moments and unfortunately not too many of those.....! But the main thing is we still have fun and the K3 sure helps in a big way in that department. 73 Tony Fegan VE3QF Don Wilhelm wrote: > Tony, > > To reduce the width on SSB, try just using Hi Cut instead of the width > and shift controls.

Does reducing bandwidth using the Hi and Lo cut invoke any roofing filters
as the appropriate bandwidth is reached? David G3UNA _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

RE: K3 Narrowing the filters on SSB

> Does reducing bandwidth using the Hi and Lo cut invoke any
> roofing filters as the appropriate bandwidth is reached? Yes, whenever the DSP filter settings result in a bandwidth equal to the next narrowest crystal filter, that narrower crystal filter kicks in. That's why reducing HI CUT works so well. As HI CUT is reduced, so is the bandwidth, but also Fc (the filter center frequency) is kept centered in the pass band. 73, Ed - W0YK _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Lets see if anyone has any opinions on this:
How about the possibility of a special single band split mode. After doing a bit of playing on this latest contest I saw possible value in a mode where direct entry automatically assumes you're going to stay on the same band. So if you want to work split and the DX station says <my_call> listening on 225 and you're on 7.085 and you're in this special mode. Then you could just switch to the other VFO and press enter 225 and then pop back and be ready to rock and roll. Not having to enter the 7 or the 00 at the end could save you a bit of time. There are times where its something like 7.225.5 and for that one could possibly setup the RIT/XIT knob to be able to pull that off in one detent. Not sure what button I'd implement this on but something in the area of freq ent seems reasonable. Would be nice if you could skip the freq ent button in this mode too as that would make times even faster but would make operation of the rest of the rig a bit of an annoyance. Sorry if my operation is a bit vague but I don't have a K3 so I'm having to go just off of what I've read in the manual and of the operation of my TS-450Sat.

Don,
At present the filter centre frequency is unchanged as the filter Width is reduced. If the centre frequency on SSB could be reduced by half the change in bandwidth then the LO-Cut frequency would remain the same. This is the same as how the Hi-Cut works. If we now add another variable so that when the bandwidth goes below about 2.2KHz, we slightly reduce the reduction in centre frequency, then this could start to raise the Lo-Cut frequency up to about 500Hz by the time we reach a bandwidth of 1.0KHz. This would allow the Width control on SSB to be used just like on CW. Just one control right down to the narrowest bandwidth. I tried your suggestion of moving the VFO at the narrower bandwidths but did not find any improvement over raising the Lo-Cut frequency. I was careful to tune in to signals close to their correct frequency and not where they sounded best. I found that a signal in the clear could be copied down to very narrow bandwidths but with QRM it was easier to copy on a slightly wider bandwidth. Of course it all depends on which side the QRM is. Maybe this topic should be renamed to "Digging in the dirt". I like looking for those very weak signals. At least my ears work fairly well, even if the associated processor is a bit suspect. 73 Tony Fegan VE3QF Don Wilhelm wrote: > Tony, > > If you loose substantial intelligibility when moving the Hi-cut to > narrow the SSB width, try moving the VFO just a bit.

Re: K3 Special Split Operation

In reply to this post by Brett Howard
If Crossband Split mode is not an available feature, when working Split in
the same band, and using your example, I would have thought that the band select control system could be used to tell the K3 that 225 means 7.225 MHz Sorry I don't know if the K3 can operate in Crossband Split mode (you stay here on 14.xxx and I'll call you on 50.xxx), but if it can and to carry on with your example, if the existing system wants all of the numbers when frequencies are entered (7.085 and 7.225), you would have to tell the K3 to stay on the same band when entering just 225 after entering 7.085. If Crossband Split is available then I would have thought that there would be some form of 'Same Band Split - Crossband Split' control, not necessarily a front panel control, which could be used just once to do that until changing bands or going into Crossband Split mode. If that is true then after entering 7.085 for the first time it might also be possible to leave out the 7 when entering the frequency for either of the VFOs thereafter when using Same Band Split, until changing bands or going into Crossband Split mode. .Anything to save time during a pileup is a very good idea IMHO :-) 73, Geoff GM4ESD Brett Howard <[hidden email]> wrote on Monday, March 03, 2008 at 4:14 AM > Lets see if anyone has any opinions on this: > > How about the possibility of a special single band split mode.

A second receiver built into the system is certainly the better option, especially when using Crossband Split, no relay noise for example. My piggy bank cannot support a K3 and the development of a new receiver, just offering some thoughts as a spectator. 73, Geoff GM4ESD _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Sorry not sure I understood that, the KRX3 is the second sub-receiver and a
lot of us are waiting for it to be released, most paid for it with the deposit for the K3. It already developed and just undergoing some changes because Wayne wasn't happy with it.

I would not recommend trying crossband split until the sub receiver is finished and the firmware
modified to allow it. Brett's proposal is stricly a shortcut for in-band split. When the firmware is done for the sub receiver you sill be able to control the frequency and other functions of VFO B by a number of ways, including the BSET function, VFO B knob and A/B. ------------------------- 73, Greg - AB7R Whidbey Island WA NA-065 K3#0009 and 0319 On Mon Mar 3 3:01 , "Geoffrey Mackenzie-Kennedy" sent: >If Crossband Split mode is not an available feature, when working Split in >the same band, and using your example, I would have thought that the band >select control system could be used to tell the K3 that 225 means 7.225 MHz > >Sorry I don't know if the K3 can operate in Crossband Split mode (you stay >here on 14.xxx and I'll call you on 50.xxx), but if it can and to carry on >with your example, if the existing system wants all of the numbers when >frequencies are entered (7.085 and 7.225), you would have to tell the K3 to >stay on the same band when entering just 225 after entering 7.085.

What about the people who don't buy the second RX? And even still its only
an idea to save time and would save time in the presence or absence of the second RX. Wouldn't you agree? -----Original Message----- From: David Ferrington, M0XDF [mailto:[hidden email]] Sent: Monday, March 03, 2008 3:28 AM To: Geoffrey Mackenzie-Kennedy; Brett Howard Cc: Crafters Subject: Re: [Elecraft] K3 Special Split Operation Perhaps we should wait for the KRX3 to be available and then use it a little, before asking for Split mods?
