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

[Elecraft] K3s throwing a "HIGH CURR" error after installing K144XV and Reference Phase Lock Option

Just what the title says  I installed a new K144XV and Reference Oscillator Phase Lock Option tonight. When I hit the band switch to go up to the 2 meter band, it thru a HIGH CURR error. I followed the directions in both install manuals precisely (as appropriate for a K3s as enhanced),

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

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

[Elecraft] K3 Band Data

I am the owner of an old K3 (Nov 2007 # 188) and now I need to use Band Data outputs. As they did not work I have been looking for the problem and found that a long time ago there was a board that sold Elecraft to solve the problem (REMIOUPGD) for K3 before December 2008, but that is no longer

[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

[Elecraft] F/S K3

I forgot to add that it also has the KXV3B upgrade, SS hardware and the 4 encoders have been replaced. All the mods are current to the last time it was at Elecraft in 2017 Selling my K3/100 SN 6010, comes with ATU, SUB, DVR, and a KBPF3 in main. Has been upgraded with KIO3B, KSYN3A's Comes with

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

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

[Elecraft] [K3] Issue with HI CUR on 12m

Back in early December, I installed two KSYN3As in my K3 SN 7071. Sometime after that, I noticed that on 12m, I’m seeing a HI CUR indication when I set the power level to more than about 80-85 watts. The K3 will back off on the power level, then slowly ramp back up until it hits HI CUR again.
