[Elecraft] Multiple Port Issues
It seems one of the most frequent posts to this list concern setting up, and configuring multiple serial ports for the K3 to do WSJT, HRD, DX4Win etc. Years ago I found the solution and although to some a bit pricey, it has never failed me and is strictly plug and play. My station will never be without a U.S.Interface Navigator now being marketed by Timewave and available from HRO. This device provides 6 FTDI serial devices on a built in USB hub that do 1) CAT 2) PTT, 3) K1EL WinKeyer, 4) FSK, 5) RS232, 6) Navigator Configuration. Additionally the Navigator has one of the lowest noise USB Codecs I have ever found for those sound card applications. A cable for your specific radio is available at an additional cost, or you can as I did, build you own. As I operate many different modes, from CW to Meteor Scatter using many varied application programs from HRD to WSJT-9 using external sequencers. I discovered, that to protect my external equipment, I needed to consolidate all the PTT functions to one source. I have a white paper describing how I accomplished this simply and easily, with flexibility for future configurations, available upon request. The final caveat, I have no financial interest in the Navigator or its marketing. It just works and I have at one time or the other tried most of the other interfaces and the Navigator is my choice. 73s Jim, W4ATK Elecraft K-Line Celebrating over 60 years of amatuer radio (1953 - ) __ 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

[Elecraft] K3/KAT500 ATU Tune Operation
Is there any firmware in the works to get the K3/KAT500 ATU tune operation to work like the K2 and KX3? I use the ATU quite often and always find it frustrating to have to hit TUNE and wait for the match, and then have to hit TUNE again to bring the rig back into receive. It's nice that all you have to do on the K2 and KX3 with the internal ATU's is hit the TUNE button and it finds a match and automatically switches back to receive when it's done.

Re: [Elecraft] [K2] Transmit Audio Problems
What's the source of the 700 Hz tone? Are you sure it is clean? If you reduce the level of the 700 Hz tone, do the spikes go down at the same rate as the fundamental, or faster?

Re: [Elecraft] KX3 on Data Contest, is utopia?
iz6gvc iz6...@libero.it wrote: Hi, is possible to imagine to work one of most important data mode contest with KX3 and 10W? Thanks, Camillo iz6gvc Yes. Many stations use 10 watts or less for data modes, including in contests. Higher power will provide more contacts and greater distances, but good atmospheric conditions and effective antennas can make QRP sound like QRO. You can use either audio-based data modes (KX3 DATA submodes DATA-A and AFSK-A) or the KX3's built-in DATA modes (FSK-D and PSK-D). In the latter case, you don't even need a computer, necessarily. The KX3 will decode and display PSK31 signals in PSK-D mode, and narrow-shift (170 Hz) RTTY in FSK-D mode. You can also transmit in these modes by using a keyer paddle; the KX3 converts the CW to DATA. The CW message buffers will work, too. KX3 Utility has a Terminal window that uses CW, PSK-D, or FSK-D along with your PC's keyboard. This provides a way to use these modes without a computer sound card -- just use the USB or RS232 cable that you normally use with KX3 Utility. All of this applies equally to the K3/10. I have operated in many RTTY contests with the KX3 running 5 to 12 W. Usually I program one message buffer with just my callsign, twice, and another with a contest exchange. When doing search-and-pounce operation, you'll very rarely even need to use the keyer paddle. 73, Wayne N6KR __ 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] [K2] Transmit Audio Problems
Anything other than a *perfect* sine wave will have harmonics which will also appear in the output spectrum. Non-linearities within the radio will also create extraneous products in the output. With a P3 or other panadapter, take a look at WWV with the radio in AM and the span around 6 or 7 KHz. They create a single audio baseband that has all the bleeps, bloops, tones, 100 Hz subcarrier, IRIG-H modulation and voice announcements, and modulate 5 transmitters with it. The 2.5 and 20 MHz signals will look pretty much like we all expect: The carrier surrounded very close by the two sidebands from the IRIG subcarrier, and when the tones are on, they clearly show up, and the spectrum is very clean. These two transmitters are apparently low-level modulated with linear amplification. The spectrum on 5, 10, and 15 MHz is altogether different. You will see the carrier of course, surrounded very close by the IRIG subcarrier. You will see the two expected sidebands from the tones when they're on. You will also see harmonics of the tone sidebands ... depending on conditions and time of day, I can sometimes see the 4th harmonic. Each of the tone sidebands will have the subcarrier sidebands close around them, as will all the harmonics. I believe these three transmitters are Class C finals plate modulated or at least that's what I read. The difference is really striking. It's amazing what a little non-linearity can accomplish. :-) 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 6/7/2014 11:02 AM, Vic Rosenthal wrote: What's the source of the 700 Hz tone?

Re: [Elecraft] K2 with KPA500 and KAT500 setup
I believe you have it right. You could also leave the AUX cable connected from the KAT to the KPA so that the KAT can interrupt the KPA’s PTT signal. You need either that or the RCA-plug cable that you described. You might want to connect the K2’s serial port to the KPA’s XCVR serial port, select RADIO=SERIAL in the KPA’s menu, and get things going that way. This is tested (by me, among others), and is known to work. If you are using the K2 and KPA/KAT with a computer, be sure to use a Y-adapter (you will have to make one) so that the KPA simply eavesdrops on the computer - K2 communication. If there is no computer, connect the two directly, then set the KPA’s SER POLL menu item to ON so that it will send serial commands to the K2 to get the band. Enjoy the setup!

[Elecraft] Elecraft CW Net Announcement
Good Evening, The local grouse have ceased drumming. I can only hear them in the distance now. Today I saw my first pair of Western Tanager http://www.allaboutbirds.org/guide/western_tanager/id They enjoy the Doug fir canopy for its insect populations. Spotting a male is fairly simple when they are out in the open :) Propagation has been up and down this week. Noise from local and distant storms is increasing each week. With the longer days the higher bands are opening and lasting later into the evening; sunspot activity has increased the QSB as well. Three large groups have sprouted in the last couple of days. Maybe a flare is in the making. Please join us tomorrow. 14050 kHz at 2200z Sunday (3 PM PDT Sunday) 7045 kHz at 0100z Monday (6 PM PDT Sunday) 73, Kevin.

Re: [Elecraft] K2 with KPA500 and KAT500 setup
True, The K2/10 does not have a keying output, but the K2/100 does have a Keyout output. Those contemplating the use of the KPA500 and KAT500 will likely have the KPA100 installed. For those who want to use the K2/10 with the KPA500 or other amplifer, read on --- For those who would like to add an amp keying line to the K2/10, I refer you to Tom Hammond (SK) N0SS's web information that is being preserved by the MMARC at http://www.mmccs.com/mmarc/n0ss/. Boards and kits are no longer available - Tom's website is now static, but the information is there including the board layouts if some enterprising amateur would like to create their own boards Tom's K2 amp keying circuit can be easily be implemented on perfboard, the circuit is not that complex. If the K2 has the K60XV option fitted, there is a Keyout signal available at the K60XV J2 pin 2 - connection to an appropriate output jack is the only thing required. There is room for an RCA jack near the key jack - just be certain the hole you drill is clear of the adjustment for the 40 meter bandpass filter inductors. 73, Don W3FPR On 6/7/2014 10:04 PM, Matt VK2RQ wrote: The stock K2 doesn't have a keying line for an amp.

Re: [Elecraft] K2 with KPA500 and KAT500 setup
One caution: don't use the ACC cable for one hop and an RCA cable for the other. The amp key interrupt relay in the KAT500 is DPDT, and the KPA500 will key if either the RCA or ACC connector key line path is connected.

You could also leave the AUX cable connected from the KAT to the KPA so that the KAT can interrupt the KPA’s PTT signal. You need either that or the RCA-plug cable that you described. You might want to connect the K2’s serial port to the KPA’s XCVR serial port, select RADIO=SERIAL in the KPA’s menu, and get things going that way. This is tested (by me, among others), and is known to work. If you are using the K2 and KPA/KAT with a computer, be sure to use a Y-adapter (you will have to make one) so that the KPA simply eavesdrops on the computer - K2 communication. If there is no computer, connect the two directly, then set the KPA’s SER POLL menu item to ON so that it will send serial commands to the K2 to get the band. Enjoy the setup!
