APF and my 2 cents - I was using predefined NORM II settings for APF, if
needed. The problem (my problem) is that I am using 200Hz filter in my S&P operation but for APF I use 400Hz filter. (it was my chioce - YMMV of course...) By switching on APF directly by holding XFIL button it will stay on current XFIL w/o possibility to have other defined... So in previous FW version I had three possibilities - standard XFIL, "contour" (DUAL PB) or APF (with wider XFIL by switching to NORM II settings in my case). What will be nice to switch FINE tuning on if APF activated. Thanks to Elecraft for keeping K3 better and better :-) 73!

It is probably true that Elecraft can never remove any existing feature
without upsetting some existing users... so the way forward would be to add the new alternatives as *options*. The point about options is: nobody is compelled to choose them! The factory defaults would usually need to stay as they are, because of the existing labels on the buttons and the front panel. So anyone who doesn't want those new options would be able to carry on exactly as before. Those who do want to select new options would have to accept that the existing 'tap' and 'hold' labels would no longer be quite accurate. For me, that would be no big deal - my first priority is always what the K3's controls *do*. But others will have different priorities, and that is precisely why new features need to be offered as *options*. But having said that... >> Question: does anybody really use XFIL? Why does the K3 have an XFIL control at all? It seems like a carry-over from the K2, where the selectivity came from the crystal filters and the XFIL button was the primary bandwidth control. But the bandwidth of the K3 has always been defined primarily by the DSP so XFIL has never made sense to me. However, AB9CA makes a very valid point that the WIDTH control requires excessive cranking at larger bandwidths. If the WIDTH, HIGH and LOW functions could be improved by making their rates of change proportional to the bandwidth, then there would be even less need or justification for using XFIL. >> Perhaps relocation of diversity there makes more sense. W4TV replied: > >No, retaining the dual context CW filter and assigning APF to XFIL >and Dual PB to the current DUAL PB function makes more sense. > Agreed, that definitely isn't the right place to relocate the Diversity function. There are already three existing functions competing for that button, without adding another. I would support an option to replace XFIL with APF as the main ('tap') function - which would then correspond more closely to the KX3 - and to bring back DUAL PB for 'hold'. >Leave DIV as SUB Hold as it is in 5.10 and make LINK available >as a programmable function (LN0;/LN1;). Having LINK as SUB >HOLD and DIV as an extra long hold is/was very difficult from >an ergonomic perspective. Agreed in every detail. Finally, on the subject of an external button-box, I don't ever want to see external boxes and macros being used as band-aids for existing controls that don't function as effectively as they could. Much more can still be done to improve the ergonomic 'rough edges' of the existing front panel. 73 from Ian GM3SEK ______________________________________________________________ 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 Message delivered to [hidden email] |

YES - I use XFIL repeatedly to shutdown the IF or restore it to
service when doing eme. I have DATA-A configured to use "FL3" which has no filter installed in order to disconnect the 2nd IF when I am running MAP65. I tap off the 1st IF into the LP-Pan, to Delta44 soundcard. Why do I do that? FL2 is populated with 2.8-KHz filter and it "sucks out at zero frequency" on the MAP65 band display. selecting FL3 with XFIL allows me to have no load from the 2nd IF. But if I want to check signal levels with the S-meter I only have to tap XFIL to restore FL2. I use XFIL several times an hour on eme. Regarding use of Diversity - that IS why I bought the KRX3 subreceiver. I ALWAYS run Diversity reception when I select the subreceiver because it is integral to my dual-polarity adaptive receiving system (used on 2m-eme). I would consider loss of use of Diversity Reception a breach of contract by Elecraft. I have over $10k invested with the K3 Diversity Rx as central feature of the system. It IS why I bought the K3.

I don't think anyone is talking about getting rid of Diversity - which is one of the differentiating features of the K3. What many are saying - and what Elecraft did in 5.10 - is that removing the second SUB "Hold" function for the generally inferior "LINK" option is appropriate. ...

Hello Arie,
I agree with you 'LINK' should not be abandoned. Please excuse my language, I would consider the idea of abandoning the 'LINK' is stupid. During APDXC 2012 in Icom HQ Osaka, I spoke to Mr. Inoue JA3FA that I did not understand why IC7800 did not have the function of LINK for both VFOA & B so that I could use the dual receivers for diversity reception. I also mentioned that their competitor K3 had that function which I often used. Skillful use of diversity reception will enable you to pick up the odds even with simple antennae. 73 Johnny VR2XMC 寄件人︰ Arie Kleingeld PA3A <[hidden email]> 收件人︰ [hidden email] 傳送日期︰ 2015年02月16日 (週一) 1:10 AM 主題︰ Re: [Elecraft] K3 Beta 5r10 and LINK Tony LINK ties both VFO's to the mail freq dial en keeps them insync when you turn the dial knob. So both receivers keep working on the same freq. What I often use i diversity listening so with two receivers and two antennas on the samen freq. Diversity puts the main RX audio on the left ear of the headset, and the Sub on the right ear. That's the normal situation. In my case, the F9-F12 buttons in N1MM contain commands to the K3 that switch the audio to my liking (that can also be done in the Config, but that takes too much time during QSO) This way I can switch listening from diversity (listen both MainRX and SubRX at same time) to only main RX (main RX audio on both ears) or only sub RX (Sub RX audio on both ears) depending on where the signal is best. The commands to do this are in the programmers manual of the K3.

> Skillful use of diversity reception will enable you to pick up the > odds even with simple antennae. Diversity is entirely different than LINK. Diversity as engaged by a one second HOLD of the SUB button in FW 5.10 (and a two second hold in prior firmware versions) uses the same synthesizer for both receivers so they are phase locked. LINK as engaged by a one second HOLD of the SUB button in prior versions of the software only slaves the two VFOs with a constant offset which means the two receivers will vary randomly in phase causing signals to fade in and out as the receivers vary from in-phase to out-of-phase and back. FW 5.10 simply moves true diversity to the one second hold of position of the SUB button - as it should be - instead of requiring a two second hold and relegates the inferior LINK to a programmable function. > During APDXC 2012 in Icom HQ Osaka, I spoke to Mr. Inoue JA3FA that I > did not understand why IC7800 did not have the function of LINK for > both VFOA & B so that I could use the dual receivers for diversity > reception.

I guess there is some confusion then as to the function of Link. Myself, I thought it was solely there for diversity mode. So, how else would one use the Link function? What is its purpose?

I have LINK in use with a 5kc difference between vfo A and vfo B and i am
constantly tuning around looking for dxpeditions who usually run split. It means for me a quick tap and i am split "up 5" in ssb. I then fine tune when they are calling "up 5-10" etc. Taking it away is simply not fair. I do not have the 2nd rcvr and i am not interested in diversity. I dont give a hoot if i am the only one using LINK, the fact remains i do and i feel i have a right to keep on using it.....Captains Call Gary Vk1ZZ K3, KX3, KPA500-FT, KAT500-FT,P3.

Link uses both VFO's, with VFO A controlling main RX and VFO B
controlling sub RX. Diversity uses only VFO A on *both* main RX and sub RX. Link memorizes the difference between VFO A and VFO B and maintains VFO B at that difference while VFO A is being tuned. If you do A>B before link, it will still be two synthesizers that are not locked, just have the same current input parameters. In my case when I do this I rarely hear the band noise spreading out into the band noise "sound stage" needed for digging out weak discreet CW signals. Diversity is a phase lock between the two RX using the same set of frequency generating sources for both RX. This always produces the band noise sound stage. Note that the sound stage is not something generated in the K3. That is done in our minds by the same mechanism that allows us to pick out a single voice in a crowded noisy cafeteria. The band noise is spread out around the "audio horizon" or "sound stage" in my "mind's ear". A discrete signal is in one place on the sound stage. My mind easily picks the discrete sound out of the spread-around noise. This is very much the same thing as listening to a stereo recording of an orchestra that begins with audience buzz, which is all over the audio horizon in my mind's ear. When the music begins I hear the violins to the left, though spread out a bit. I hear the tuba at a specific spot on the right. Once a K3 diversity RX operator has learned to use "sound stage" diversity, it is easily an S unit advantage on RX for a station at or in the noise that you can't see on the S meter. For me diversity is always on 160 through 40. Anything that craps diversity, for me throws away an S unit. If you are not getting the sound stage trying to use diversity, you really are not getting the benefit, and have some fun ahead of you when you do. 73, Guy K2AV On Sun, Feb 15, 2015 at 9:15 PM, Tom Blahovici <[hidden email]> wrote: > Hi Joe, > I guess there is some confusion then as to the function of Link. > Myself, I thought it was solely there for diversity mode. > So, how else would one use the Link function?

I am not Joe, but I can answer your question.
In diversity mode, the K3 operates just like a single receiver as far as the controls are concerned (except for the audio effects attributed to diversity). In other words, if you are operating SPLIT, you would tune to the DX station with VFO A and transmit on VFO B. To listen to the pileup (on your TX frequency VFO B) you would hold the REV button to listen to the pileup as long as you hold the button, but if you wanted to not hold the button and switch to hear the pileup, the A/B button can be used to switch VFOs until you wanted to switch back (with the A/B button). Since you have both the mainRX and the subRX, it makes more sense to use the subRX in its normal mode where you set SPLIT on and listen to the DX on the subRX while transmitting on the mainRX frequency (the subRX frequency does not have transmit capability). There are some ways to reverse this, but I will not go into details, this is the 'fundamentals' of split operation. For linked VFOs, imagine you want to work DX operating with a fixed 2 kHz split while the DX station is changing his TX frequencies while maintaining the 2 kHz split - that does not happen very often (maybe never). You can set SPLIT on and separate the VFOs by 2 kHz then invoke LINK. The VFOs will always be 2 kHz apart. I don't think that situation occurs frequently. The only remote occasion I can foresee is for the QRP Foxhunts, but the Foxes rarely will operate SPLIT. Normally, the DX station stays on the same frequency and you would want to leave the RX VFO tuned to his frequency while you would want the TX VFO to tune to either the last station worked or a clear frequency within the pileup. The current TX VFO is displayed in the K3 or KX3 display by an arrow. Pay attention to that arrow lest the "up cops" become irritated with your transmissions. IMHO, the changes made in 5.10 simplify the use of the SUB button. No more short hold of the button to link the VFOs and no long hold to enable diversity. How many times have we seen posts to this reflector saying that the VFOs track each other. This is a result of the difference between a long hold and an extra long hold of the SUB button. Relegating the linked VFOs to a programmable function is a good idea IMHO. 73, Don W3FPR On 2/15/2015 9:15 PM, Tom Blahovici wrote: > Hi Joe, > I guess there is some confusion then as to the function of Link. > Myself, I thought it was solely there for diversity mode. > So, how else would one use the Link function?

OK,
Thanks for the explanations. Very clear.

My point all along ... it's a real PITA to go through LINK every time I want to select diversity. However, I would make one concession ... since diversity requires the KRX3, if the KRX3 is not installed then allow a one second hold of the SUB button to select LINK. Otherwise, LINK is simply an annoyance. 73, ...

I use Diversity and I use Lock.
With the Rx antenna and the Tx on the two different receivers and both of them locked, I find I copy stations sometimes better this way than with diversity. There's a slight attenuation with diversity and not so with the main & sub linked. It depends on the individual signal for me to know when to use the main Rx alone, Link, or Diversity. Each one of them has their own benefits. 73, Gary KA1J > Hi Joe, > I guess there is some confusion then as to the function of Link. > Myself, I thought it was solely there for diversity mode. > So, how else would one use the Link function?

I never, ever use LINK. I use diversity often. I like the beta because it enables me to use the SUB button to toggle diversity, thus freeing up one of the programmable function keys for something else. I found the long hold unusable.
