Re: [Elecraft] 700 Hz roofing filters
I'm a 99% cw op, mine are 2.7 (soon 2.8) 2.1, 500, 400, 200. Sub is 2.7, 500. The 400 I use always for contesting. Doing CQ WW RTTY as a low power multi single, this weekend as first time ever on this mode have WinTest es mmtty es setup for AFSK A. What is the preferred filter width min es max in these crowded bands. Hopefully the P3 will give me an edge squeezing in somewhere.

Re: [Elecraft] P3 question on the noise floor
Ross, I think I may have missed the original message. Anyway, if I understand right I would suggest doing a configuration reset. (Hold the MENU/LABELS key wand then hold the POWER key until the Configuration Reset message appears on the screen.) If that doesn't work you might try upgrading P3 firmware. There have been some changes in the way reference level data is saved in EEPROM. The latest version is 00.36.

[Elecraft] {Spam?} P3 display "expansion" when tuning K3
Hi there, When tuning the K3 the dynamic range of signals and noise on the P3 display expands considerably when I turn either the main tuning knob or fast tune via the CLR knob. It settles back as soon as the knob is not moving. (The scale grid doesn't change). I find it rather disconcerting, as the "expansion" makes the original spectrum pattern hard to recognise. Of course you can just QSY without this effect using the markers, but often I prefer to listen for anything in between as I tune to a signal of interest. Is this behaviour normal, or do I have a bug? Also getting the problem of the bandpass marker appearing as USB when on LSB. Is this being fixed in the new beta? Thanks for any info from the forum.

Re: [Elecraft] 700 Hz roofing filters
I feel compelled to state my objection to any TX capability from ALL amateur transceiver manufacturers to NEVER allow TX bandwidth in excess of 3Khz..period. ESSB is unwarranted and a waste of bandwidth and creates havoc wherever it is used. In VK we have a small minority who insist on ESSB operation and whilst we can all find alternative frequencies not suffering from QRM it should be no surprise to all that sure enough, on 17M were two stations running ESSB on 18.130 or right in about the centre of the SSB portion of the band. We all love to experiment with different modes but I have to admit I must be pretty darn slow (or worse) as I do not see why EESB is worth experimenting with. But then I may be just too slow..or worse..to understand.

Re: [Elecraft] 700 Hz roofing filters
Hi Joe et al, I'm going to hazzard a guess here as to why Elecraft dont allow the 13KHz filter for AM/ESSB TX. Because it's illegal. SSB is called mode A3J in most of the legal documents that govern our hobby. The reason why the mode is called A3J in all the legal stuff is that the 3 is the maximum bandwidth in khz that is permitted.) Thus, anything more than the 3KHz SSB bandwidth is against the laws that govern us. The F.C.C. in the US of A and here in Australia, A.C.M.A. both allow a maximum of 3KHz for SSB TX bandwidth on any HF band. So it would be a fair bet then that because the K3 is a FCC type approved radio that part of that type approval includes that it must not transmit SSB bandwidths that are wider than permitted.

I once had a 1 kHz filter but quickly discovered in casual DXing on 160m that adjacent signals were pumping my AGC. I prefer a low pitch for weak signal DXing (my preference is 270 Hz but the K3's 300 Hz is acceptable). Because the K3's MCU shifts roofing filter passbands such that the low end always cuts off at 200 Hz, if you use a 1000 Hz filter with a 300 Hz pitch, the actual passband is 200-1200 Hz, so a signal 900 Hz away (1200-300) will pump your AGC. If you use 500 Hz pitch, the passband remains 200-1200 Hz, so a signal 700 kHz away will pump the AGC. In a crowded contest or large pileup, this simply doesn't cut it. 73, Bill -- View this message in context: http://elecraft.365791.n2.nabble.com/700-Hz-roofing-filters-tp5556478p5557079.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] MCU 4.12 DVR Mon
Hi Martin, The new DVR MON adjustment (set up using CONFIG:TX DVR) only applies to DVR playback in transmit mode. DVR playback in receive mode can be accomplished with the AF GAIN control. The reason we added this feature is that some operators only want TX monitoring when the DVR is playing back, rather than at all times. Or, they want different levels for regular transmit MON versus DVR MON. 73, Wayne N6KR On Sep 21, 2010, at 2:02 PM, DM4iM wrote: > Elecrafters, > when hitting AF PLAY i notice that you can only adjust the DVR MON > level > when you are actually transmitting.

Re: [Elecraft] 700 Hz roofing filters
Hi Don, I agree. That is why I bought a 1 Khz filter when I got my K3 in 2008. I just use the DSP set between 500 and 1000 Hz. My CW operating is about the same as yours. If I need to use a sharper filter than that, it is likely due to QRN rather than QRM, and the DSP works fine for that. Including the NR section.

Re: [Elecraft] 700 Hz roofing filters
Karl, I can only speak for myself, although apparently some have agreed with me. I have ordered one, and when Gary first suggested it, I encouraged him. I do not operate many CW contests, and do not chase DX with a fervor as some do. My preferred width for general CW tuning is 700 Hz. The DSP filtering will take care of the rest for me. If there are so many undesired CW signals on the band that the DSP cannot handle, I am likely not to be operating there anyway. So it gives me a good general purpose CW filter of a width I normally use. Others are free to agree or disagree, but that is what I like. 73, Don W3FPR On 9/21/2010 4:18 PM, Karl Marderian wrote: > Why are these so popular?

Re: [Elecraft] K3: Passband Offsets per Mode
Rich, you win the prize. Exactly and that is a scenario that in my transition from the FT2000 to the K3 that I was having trouble with. If I have tuned to a signal on 7.1MHz, that signal will be in the center of the selected filter. DM-780 was telling me it was 1.5 +/- kHz away. When I would shift the IF to receive say a lower frequency signal in the waterfall of DM-780 then I would be out of the pass band of the filter and PANIC!, no power out. I just knew there was an explanation sitting right there before me, but for some reason just could not quite get there.

Re: [Elecraft] K3 - FSK question
To key the K3 in FSK D from software like MMTTY, you need a keying circuit (typically a transistor switch) between the TxD signal line on a serial port and pin 1 on the K3's ACC connector. There are several different ways to do TX/RX switching (PTT), but one of them is to use a similar keying circuit between the RTS line on the same serial port and pin 4 on the ACC connector. Both of these circuits are referenced to signal ground on the serial port and pin 5 on the ACC connector. To transmit RTTY in AFSK A, the connection to pin 1 of the ACC connector is not used. Instead you need an audio cable between the radio's LINE IN jack and your computer sound card's LINE OUT jack. You also need some method of TX/RX switching (PTT), just as in FSK D. To receive RTTY, regardless of whether you are using FSK D or AFSK A you use an audio cable between the radio's LINE OUT jack and your computer sound card's LINE IN jack. Now for your question about the bandpass in various digital modes. First, PSK D mode is not really a software mode. It is for operating PSK when you don't have a computer available. You cannot transmit from Digipan in PSK D. If you have a computer and you are using software like Digipan, you use DATA A mode for PSK, not PSK D. DATA A mode is very similar to USB. The dial reads the BFO or suppressed carrier frequency, but the actual signals being copied are higher in frequency. If you use the default filter settings, you will be able to copy signals between 1300 Hz and 1700 Hz above the dial frequency, and you should see noise between 1300 Hz and 1700 Hz on the waterfall. If you tune the dial to 9998.500 kHz, you should be able to hear the WWV carrier at an audio pitch of 1500 Hz, and there should be a steady trace in the waterfall at 1500 Hz. PSK D is different. It is still a USB mode, but the filter centre audio frequency is 1010 Hz instead of 1500 Hz as in DATA A, so what you see on the waterfall with default filter settings will be between 810 Hz and 1210 Hz. In PSK D the radio's dial readout is 1010 Hz above the BFO frequency. If you tune the dial to 1.000 kHz, you will hear the WWV carrier at an audio pitch of 1010 Hz, and see a steady trace at 1010 Hz in the waterfall. The two RTTY modes, AFSK A and FSK D, are both lower sideband modes. You can choose among four different Pitch settings, which are labelled by the RTTY Mark frequency: 915 Hz, 1275 Hz, 1445 Hz or 2125 Hz. Whatever Pitch setting you have chosen determines the filter centre frequency - the centre frequency is 85 Hz higher, i.e. 1000 Hz, 1360 Hz, 1530 Hz or 2210 Hz. The dial always reads the actual Mark frequency, not the BFO frequency. With a Pitch setting of 2125 Hz, when you tune the dial to 1.00 kHz you will hear the WWV carrier at an audio pitch of 2125 Hz and see a steady trace at 2125 Hz on the waterfall; similarly for the other Pitch settings. 73, Rich VE3KI NR4C wrote: > Hi, I'm new to the K3, (Aug 2010 sn 4536).

Re: [Elecraft] [OT] Frequency Guide
A couple of points: 7040 has been used as the QRP frequency CW in the USA, but elsewhere in the world it has always been 7030. The ARRL new plan is an attempt to bring the USA into conformity. 40m bandplans changed last year with the increased allocation in Region 1 after the broadcasters moved away. 7000-7040 is now CW only, PSK is allowed above 7040 and SSB (Region 1) above 7050. Unfortunately PSK and other data operators in Europe seem to turn a blind eye to the bandplan and insist on using 7035. 73 Dave G3YMC -- View this message in context: http://elecraft.365791.n2.nabble.com/OT-Frequency-Guide-tp5553267p566.html Sent from the [HAM] mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3: Passband Offsets per Mode
Jim, You need to separate what your software is doing from what the radio is doing. If you turn the radio on without using any radio control software, and if after changing modes you press and hold the SHIFT button, the radio will change to its default (NOR) filter settings in that mode. The defaults are (or at least, this is what they are on my radio): SSB: 0.15 kHz to 2.85 kHz CW: PITCH - 0.2 kHz to PITCH + 0.2 kHz DATA A: 1.3 kHz to 1.7 kHz AFSK A and FSK D: PITCH - 0.2 kHz to PITCH + 0.2 kHz Note that the PITCH settings in CW and in RTTY (AFSK A/FSK D) are separate. Evidently the default bandwidth in CW and DATA modes is 0.4 kHz, and in SSB it is 2.7 kHz. The default centre frequency is the selected PITCH in CW and RTTY modes, and 1.5 kHz in SSB and DATA A. If you change any of the shift/width or lo/hi cut settings, the radio will remember the changed settings on a per-mode basis. The remembered settings persist through power on-off cycles; turning the power off and on does not restore the defaults. If you change the bandpass settings in one mode, that change will have no effect on other modes. All four DATA sub-modes change width and offset from the default centre frequency together, although the default centre frequency changes between sub-modes. (Actually there are two remembered settings per mode, labelled I and II - see the Owner's Manual for details.) If you set everything back to the defaults, turn your control software on and change modes from the software, and you discover that the resulting bandpass settings are different from the defaults, that tells you that the software must have sent commands to the radio to select bandpass settings different from the radio's defaults. In that case, you would have to ask the software developers why they chose the particular settings they did. 73, Rich VE3KI __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] K3 - FSK question
What software were you planning to use, MMTTY or maybe DM780. I know MMTTY supports "true FSK" as does the K3. Not sure about DM780. And yes, both of the above use the sound card for receive. The K3 will decode RTTY but the display is limited and as far as I know there is no provision for a remote terminal, so I would go the sound card route. On your third question, I am curious about that myself and awaiting an answer from one of the gurus.

Re: [Elecraft] K3 CW keyer issues
True, but this wasn't about those keyers. It was about the variations in the logic used in modern iambic keyers with dot and dash memories. And even those variations didn't become an issue until keyers were built into rigs. Fortunately, virtually all keyers today use one of two basic logic modes, so it's pretty easy to figure out which one works, once the operator realizes there *is* a difference. This wasn't the first time someone thought a keyer was defective because they stumbled across one using the mode they hadn't used in the past. It was a good question to raise.

[Elecraft] K3: Passband Offsets per Mode
Sorry about that, I did not specify the radio or the starting mode(s) For instance: Using DM780 waterfall, the USB/LSB passband is .1kHz to 2.9kHz. Change to CW and the passband is .1kHz to 1.9kHz. Change to DATA (DATA A) and the passband is .8kHz to > 3.0kHz. Is this normal or did I miss something really important in the set up somewhere? I thought the DSP is just not set up to the filter, but that allowed you to receive lower/higher frequency data signals, but of course transmit power goes to zero out of the passband. Just does not make sense... Something has to be wrong.Been beating myself up with this for a while just wrapping my mind around the "problem".

[Elecraft] K3 Memory tuning
Is there a way to use a knob to quickly "spin" through the memories? I have not found the way to do this. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 CW keyer issues
Heck, keyers went way back into the late 40's, if I recall correctly.. I played around with a two 12au7 HB tube keyer in 1960. The tubes worked fine but the output keying relay was a real problem. One had to adjust contact spacing and spring tension on the relay to get it to work. It really didn't work very well above 25 wpm. Paddle was a bug with a rubber band on the dit arm and rewired dash contacts. The W9TO keyer came along in the same era. The relay problem was solved by using a sealed mercury whetted relay. It could do 65 WPM. It had an awful sounding sawtooth monitor.. Later I sprung for a single lever ELKEY paddle Kept it about 25 years until the Curtis single IC keyer came along. I built that into my TS-520 and published an article in CQ about the mod. To my knowledge it was the first within rig keyer. Then came a multi IC HB keyboard keyer. That was wonderful. It had a few memories. Then came computers and computer keyboard keying with HB coding and logging on a Radio Shack computer. I finally ended up abandoning keyboard keying in favor of a pico keyer mounted right on the 40 year old single lever paddle.. Pico keyer for ragchewing and fills, computer keying for contests. Never made the change to a two lever paddle. Doubt I'll ever do it. BTW Iambic A on a single lever keyer also has the extra dit problem. I must use iambic B. It has been interesting. 73 de Brian/K3KO. The key paddle was a bug with the dit arm constrained by a rubber band and the dash paddle rewired to have an independent connection.

Re: [Elecraft] K3 CW keyer issues
My K2 internal keyer can not achieve a correct weight (50% duty cycle of dots). The minimum setting of 90 is still too heavy, except for at low speeds, where its acceptable. Anyone else having observed this, or is this just my K2? I am using external keyers (CMOS Super keyer and Winkeyer) for my K2 and K3 anyway, so really don't bother. Just being curious. 73, OZ4UN -Oprindelig meddelelse- Fra: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] På vegne af Fred Jensen Sendt: 21. september 2010 01:09 Til: Elecraft Reflector Emne: Re: [Elecraft] K3 CW keyer issues On 9/20/2010 3:24 PM, DOUGLAS ZWIEBEL wrote: > I agree with the comment about Iambic A vs B option.

Nor have I ever mastered the fine art of squeezing gently. Too old I guess. I get perfect keying from my K3 using the HexKey, and so far as I know, it has never burped, belched, or stuttered. I have ... but not the radio. In contests when running N1MM with a USB WinKey, I use the K3 internal keyer for fills and requests and I've never experienced a problem there either even though N1MM is polling the radio. My K2 exhibits a very tiny, just noticeable occasional "irregularity" but it is very rare and not a problem. Incidentally, the HexKey is markedly smoother and better than either of my two "vanilla" Benchers with the spring. 73, Fred K6DGW - Northern California Contest Club - Celebrating our 40th year on the air - Look for stations signing "/40" - Info at www.nccc.cc/40th __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] CW keyer issues
/Mode A? No wonder you're having trouble with the letter C. Mode A can't remember that last command. That is why I use mode B. The problem isn't the K3's keyer. Steve/ I'm sure Mode B is fine Steve, it just wasn't around when I started playing with twin paddles. The K3 keyer is fine too, I just had to adjust my lousy timing to suit. 73 Norman - GM4KGK __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
