Re: [Elecraft] K3s throwing a "HIGH CURR" error after installing K144XV and Reference Phase Lock Option
Update... 1) Strictly speaking, removing the RefLock option board and associated SINGLE TMP cable did not "fix" anything... Still have the "HIGH CUR" error. 2) Incidentally, IF you fire the K3s up on ANY other band (after disco and reconnecting power to clear error) WITH the KXUSB cable connected to the computer AND the K144XV "RS-232" port, and THEN switch from any other band TO 2 meters, the status light flashes once as expected (ready for firmware). BUT, the K144XV Utility will NOT connect to the K144XV. Then, of course, if you shut the K3s down while on 2M band and remove the KXUSB cable from its port, then power back up a) Powers up, status light flashes once or twice as expected. b) the K3s shows ANT3 briefly, and then starts trying to display the power-on banner, but is interrupted repeatedly by the HIGH CUR error which remains after the banner scroll completes. c) You have to power down, and disco/reconnect the power to reset. I pulled the left side of the case off ans inspected the IF IN and IF out cables to verify that they are connected correctly AND still fully plugged, and had NOT been pinched off. I think I will try again, with the ANT 3 cable disconnected to remove the BNC cable assembly as a possible cause I'm reaching here now. _*Question:*_ Is there any chance that having the "grip" portion of ANY of the TMP connectors making contact with the K144XV enclosure a "problem"? The ANT3 TNP board connector is set at a slightly OFF angle, and the TMP outer (coax shiield) might be touching the enclosure. Just trying t figure out what is "wrong", and if it anything I have control over... 73, __ Clay Autery, KY5G (318) 518-1389 On 01/11/20 22:01, Clay Autery wrote: Just what the title says I installed a new K144XV and Reference Oscillator Phase Lock Option tonight.

[Elecraft] Elecraft CW Net Announcement
Good Evening, It has been a very wet week. Today it varies between constant rain and when the sound level drops I know it's snowing. Today I am right at snow line but by midweek it will drop a few hundred feet. According to https://spaceweather.com 2020 has had only one spotless day. A series of small cycle 25 spots have been moving across the sun. No real sunspot groups but it is a change. Another few months and maybe we'll be able to see larger spots more often. Patience is necessary. Don't hold your breath but Betelgeuse may nova one of these days. It has been 'fainting' lately with a magnitude down to +1.12. A supernova only 350 light years away will be pretty spectacular. Please join us tomorrow on: 14050 kHz at 2200z Sunday (2 PM PST Sunday) 7047 kHz at z Monday (4 PM PST Sunday) 73, Kevin.

Re: [Elecraft] K3 Band Data
Pedro and all, The first K3 had band data outputs that were driven by open drain FETs. That means that the receiving unit had to provide the pullup voltage to operate properly. Since almost no one in the amateur community understood the benefits of using open drain or open collector devices to drive the attached device (which would provide the pullup voltage), that was changed so the K3 provided the pullup voltages early in the life of the K3. If your K3 does not provide voltage on the band data lines, then you can add the resistors to +5 volts if you install the REMIOUPGD resistors to the band data lines. This upgrade kit is no longer available from Elecraft, but the instructions can be found in the archives. If you are also wanting to upgrade your K3 with the USB interface, you can install the KIO3BUKT3 which replaces the REMIOPGT kit and provides pullup resistors on the band data lines. 73, Don W3FPR On 1/11/2020 6:53 PM, Pedro, EA4KD wrote: I am the owner of an old K3 (Nov 2007 # 188) and now I need to use Band Data outputs.

[Elecraft] K3S USB codec Main and Sub - Left and Right
Hello all. I have 2 independent Xpol channels that I want to decode separately. I have tried unsuccessfully to achieve this. Details are as follows Xpol yagi - CH1 is -45 deg, CH2 is +45 so in an X format 2 channel 144/28 transverter Ch1 is Main - Ch2 is Sub What I want to do is use the USB codec and the left channel for the main and the right for the sub RX, WSJT-X allows for selection of left or right channel on a stereo audio stream. If I use my soundcard this works fine. BTW I do not need a coherent RX, I am not trying to do adaptive, I achieve this by splitting the 28 MHz channel and use a coherent 2 channel SDR, this work FB as well. It must be possible I think but I can't figure out how. Any advice would be appreciated. 73 Conrad PA5Y __ 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] [K3] Issue with HI CUR on 12m
Is the power supply at 14 volts or so? And what does the radio show the voltage to be in key down transmit into a dummy load. Low voltage will demand more current to produce 100 watts. I run my supply at 14.25 V no load and the radio shows 13.8V during 100 watts transmit. Voltage drop should be 0.5 volts or less.

Re: [Elecraft] [K3] Issue with HI CUR on 12m
Bill, Is this into a dummy load (bypass the ATU or tune the ATU into the dummy load). If it is into an antenna, there are a whole lot of guesses about how the antenna behaves with higher power levels than your antenna analyzer shows. So check it with a dummy load to eliminate the possibility that the problem is in the antenna. Put an external wattmeter in line with the dummy load to eliminate questions about the calibration on the K3 wattmeter. If you can measure the actual current drawn, that would also be helpful. 73, Don W3FPR On 1/11/2020 11:18 AM, Bill Coleman wrote: Back in early December, I installed two KSYN3As in my K3 SN 7071.
