[Elecraft] [K3S] "Hardware Sequencer" WSJT-X?
As in WSJT-X 1.70 online help: "Set Tx delay to a number larger than the default 0.2 s to create a larger delay between execution of a command to enable PTT and onset of Tx audio. For the health of your T/R relays and external preamplifier, we strongly recommend using a hardware sequencer and testing to make sure that sequencing is correct." What would this "hardware sequencer" and need I be concerned with a K3S?

[Elecraft] K3S Shift Setting for WSJTX
Hope this is not a dupe. I sent it over an hour ago and nothing showed up. I am trying to tweak my WSJTX setup. What is the recommended shift for the K3S while running WSJTX? I have the 2.8 khz SSB filter installed. I am using a width of 4 khz and using the radio in split mode. 73, Tom - KQ5S __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] Keying CW in SSB Mode
All, That may be true for CW sent by FLDIGI or another data mode application - it simply feeds a (hopefully) single tone to the SSB generator. The K3 CW in SSB mode is different because it is real keyed CW from the paddles of keying input. Yes, the carrier is shifted by the sidetone pitch so a station listening in SSB mode will hear the tone. 73, Don W3FPR On 7/3/2017 4:00 PM, Fred Moore wrote: Ted, it's not a great strategy any time, and yes most likely that is what was going on.

[Elecraft] W0CZ camping notes
Hi to the group I have been busy camping with my KX3,KXPA100, 12 volt battery and solar power. I will comment on things that have worked out well for me. I have a 16 foot Scamp travel trailer. There are pictures on QRZ.COM for W0CZ My antenna is a vertical which is 33 ft of speaker wire supported by a MFJ-1910 pole on the drawbar of my camper. I mounted a DX Engineering MAXI-CORE HIGH POWER MULTI-BAND UNUN DXE-UN-43 to the frame of the camper with the antenna to the +terminal and the frame of the camper to the - terminal. I ran 6 ft of RG8X to the KXPA100 with built in tuner and the KX3. My battery is a 110 amp deep discharge wet cell. The solar panel is 100 watts from Home Depot and I have a simple solar regulator the switches off at 14 volts DC and on at a lower voltage. I find at 100 watts in bright sunlight the solar charges at about 4 amps while I am sending CW and drops back to almost nothing when I am receiving. I can discharge the battery on the air in the evening and if there is sunlight it charges back up in a few hours in the morning. I ran 1B-ND at 5 watts battery and solar for field day. I had 174 contacts using all bands 80, 40,20,15, and 10. My furthest contact was Hawaii from North Dakota on 20. I felt the antenna did a good job on each band using only 5 watts. I am camping at Lake Bemidji. State park in MN this week end. This morning I added a loading coil for 160 meters to this antenna and worked WB0BIN in Sabin, MN at 8:30AM. He is about 100 miles away and it was weak copy for both of us with 100 watts of SSB on each end but we talked for about 20 minutes. I do not use a loading coil on any band other than 160 although I could use it on 80. One final thing. There was talk on this reflector earlier about the noise potential for Honda generators. The big camper beside me brought a Honda 3000 generator and has run it off and on all week end. He has it located about 20 ft from my antenna. I find there are powerful places of noise about 5 kHz wide that run about an S8 or -80 on my PX3. Away from these spots my noise is S0 to S1 with -115 to -105 on my PX3. These spots drift around when he first turns it on but than they tend to stay in one part of the band. The noise peaks were about 27 kHz apart. That may be one reason some people say the Honda makes a lot of noise and others do not see the noise. If the noise is where you want to work that is not good. I have been making contacts where the noise is low all week end. I am also finding no noise on 20 CW so maybe the higher frequencies are filtered. In summary. My only major change to my system this year is the DX#-UN-43 and I feel it has made my antenna work much better. I base my opinion on all the contacts I am making easily on all bands this year compared to the frustration I had the last two years. Yesterday I worked a ham in Missouri running an MFJ-9020 at 5 watts and a vertical. We had a 45 minute QSO and that was before the Honda came. I ran the KX3 with preamp on, attenuator off and AF gain at 60 but we made it and I thought that was a good indication of the natural low noise level in the park. I have worked several 100 watt stations using dipoles and verticals and we are having about equal copy both directions. 73 and feel free to try or not any of my ideas. Ken.

Re: [Elecraft] Idea for the P3
Paul, The P3 does not have a digital data stream output, and I am certain what it has is not compatible with any input to the computer. You can add the SVGA option to obtain a greatly enlarged display, keyboard support for entering data mode text or CW, and display of the K3 decoded PSK31/63, RTTY or CW. If you want to continue to use the SoftRock in conjunction with the P3, there is an IF OUT from the P3 which will allow you to do exactly that. BTW, some other hams used my K3 with P3 for the CW station at Field Day. At several points they commented "It is like shooting fish in a barrel!". They ended up looking at the P3 rather than at the K3 display most of the time although they tuned with the K3 VFO knob and did not try to point with the marker and tap the knob to QSY. 73, Don W3FPR On 7/3/2017 2:53 PM, Paul Wilton wrote: Having been playing around with the P3 for the first time, can I suggest a future feature please.

Re: [Elecraft] Old Style Sub Receiver Wanted
Chris, You might have better success asking for an old synthesizer board that someone has removed when they upgraded the synth in their K3. Then buy a new KRX3 with whatever filters that you want. As far as I know, the only change to the KRX3 has been the change to new synthesizers and the capacitor that was added to the 8 volt regulator output. That last change will not change the operation of the subRX. If you do it that way, you will be certain to have all the pieces necessary to install the subRX and you can store the new synthesizer until the time comes when you are ready to spend the $200 for the other synthesizer board. 73, Don W3FPR On 7/2/2017 3:33 PM, Christopher Soames wrote: Hi looking to fit the old type of Sub Receiver in my K3, however Elekraft don't have any they only have the new ones left.

Re: [Elecraft] Idea for the P3
There is an option for the P3 that adds an SVGA video output [plus a few other features] which can drive a large monitor. If however, you mean access to the internal data stream from the FFT, I don't believe it is available. It would be a nice featurefor remote operators. I operate W7RN remotely from my home. When my K3 is in TERM mode controlling the remote radio, my P3 sees the last frequency I was on locally +/- 10 KHz [I usually leave it on 20 KHz span], usually on 80 meters from the previous night.

The only option I would have now is about 60 km of RG-58 to bring the 1st IF down to my P3. [:-)) The REALLY cool option would be an IP interface and a P3-ish display for the control end, also with an IP interface. I fear however that, although the number of remote operations is growing, it's still too small a market to make something like this profitable for Elecraft. 73, Fred ("Skip") K6DGW Sparks NV USA Washoe County DM09dn On 7/3/2017 11:53 AM, Paul Wilton wrote: Having been playing around with the P3 for the first time, can I suggest a future feature please.

[Elecraft] Idea for the P3
Having been playing around with the P3 for the first time, can I suggest a future feature please. Whilst the built in display is very nice, it would be helpful if it were possible to get the spectrum data in a PC in realtime (ish). There are a couple of applications for this but the main one is to integrate the waterfall/spectrum with DX spots. At the moment I run N1MM+ for VHF contesting. My station is optimised for Search and Pounce (S&P). I have an IF tap into my K2 and use a soft rock plus USB sound card to get a waterfall band map using Waterfall Bandmap(WBM). WBM integrates with N1MM+ and shows cluster spots/stations I have worked) along the frequency axis. Hence if I see signals in the waterfall I can quickly see if I have worked/need them. N1MM+ has also introduced a similar spectrum display but that only works with the IC7300 or with WBM. Hence it would be really great if the P3 could offer a data stream out. It would be something for that spare USB connector on the back panel of the SVGA option - although I appreciate that it would need new hardware.

[Elecraft] Keying CW in SSB Mode
I wonder if this explains something I ran into during FD. On several occasions – usually late at night – I was able to do some running, all on CW. Five or six times over several hours I heard stations calling me way off my frequency. It seemed like a Khz or more, though I didn’t measure it at the time. They were outside the passband and I heard them only when, after a CQ, I tuned the RIT widely on either side. I wondered why that would be happening. I certainly wasn’t the target of a pileup. One possibility I thought of was that those callers had forgotten to cancel split after the last time they intended to use it. But this thread about audio tones keying CW on SSB suggests another. Is it possible that they were using CW keying on USB or LSB which resulted in a frequency offset of, typically, 600 (or, as Don suggests, 1200) Hz? If so, it seems like it wouldn’t be a great strategy during a contest on a crowded band.

It is late here and the fingers do not work well. Fldigi uses audio tones for keying, and you need to be in SSB mode (typically USB or DATA A) to transmit on the proper frequency - CW included - but I would expect twice the sidetone pitch. Use DATA A mode when trying to send CW via the Fldigi CW mode. CW is "just another digital mode" although one that can be decoded by the human brain for those who know morse. It uses audio tones to send CW, do the carrier frequency USB frequency will be the transmit frequency plus the frequency for the sidetone in Fldigi. 73, Don W3FPR On 6/29/2017 11:26 PM, Terry Brown wrote: > I have a KX3 connected to a Signalink and Fldigi.

Re: [Elecraft] KX1 Builder's Alert
Gary, I think that Builder's Alert disappeared some time ago. It is easy, just remove L3 and remove the turns and rewind it like any other toroid with 18 turns. 12 inches of red #26 wire will do it. Wind in the same direction as the other toroids - if you wind it in the wrong direction, the core will want to sit sideways and interfere with the installation of the KXAT1. If you have firmware 1.01 installed in that older KX1, you will need KX1 Firmware 1.02. That should be provided at no cost - tell the sales office that you purchased the KXB3080 option and need the firmware. I believe that policy is still in place. 73, Don W3FPR On 7/2/2017 3:19 PM, Gary wrote: Howdy, I am adding the 30/80 board to a an older KX-1 and I need a copy of "KX1 Builder's Alert, Modifying Final Amplifier Choke L3" for instructions on how it should be re-wound.
