Mike, Keep it to "KISS mode" --- You only need an external soundcard - the K3 has isolation transformers built into the Line In and Line Out circuits. That means that you do not need any complex interface box to provide that isolation. The soundcard audio levels will be in the computer

Neil, I believe you can use USB1 or USB2 cables on a USB3 box but your transfer rate will fall to the lowest number USB device in the line. I know that is the case with 3 to 2 so I¹m assuming it to be the case with 1. Besides, the KIO2 is only talking at 48oo baud.That said, the FTDI Chip set

Re: [Elecraft] K3 - WSJT-X help

Steve, The KX3 has a built-in protection against audio overload. If there is too much audio, it shuts down the audio chain. Take a look at your mic gain setting on the KX3 - it is best set to mid-range. The resolution between steps is much greater at the low end and high end of the mic

Re: [Elecraft] K3S/P3/KPS500/KAT500 Restart Woes

Are you powering the P3 from the K3S?  May have blown an internal fuse in the K3S 12V aux feed. KPA500 does not power on.  Is the switch on the back ON? Yes, recent WSJT-X update did change some of the TX audio level values.  You will need to check the SPKR value on your computer, about 30%

Re: [Elecraft] K3 - WSJT-X help

YES, on my KX3.. I have seen (when I change modes, often) that I have zero ALC (not 4/5 bars).  IF I turn the mike gain up, still zero.  AT THIS POINT, I turn the mike gain to zero and start turning it up.  The mike gain was too high and starting over works...  FT8 is working again.  I also

Re: [Elecraft] KAT500 auto trainer

I have not Andy, but I have, and often use, used K3_EZ for the K3 internal tuner to measure/graph VSWR across an entire band. I suggest this capability belongs in the KAT500 and KPA1500 firmware, if it can fit. I have enough tedium in my life. Automating this training is a valid need.

I am not sure if you are trying to power up the P3 with the K3 off, but If you have the P3 powered from the K3 and have the internal jumper set to power on with K3.  Then the P3 will only come on when you power up the K3. Just a thought. Rich On 12/7/2019 11:13 AM, MaverickNH

[Elecraft] KAT500 auto trainer

Popular wisdom is that KAT500 should be trained for all frequencies in a band and then operated in manual mode. This is what I do at my station but I find the training process to be a bit tedious and I'm considering automating the training process. My idea is that, within the current band,

Re: [Elecraft] K3S driving an Alpha 86

No problem with the ALPHA amplifiers - the switching voltage is approx. 24 V @ 350 mA. The K3S MOSFET switch will switch up to 200 V (absolute MAX.!) and several amperes. But to make sure connect a voltmeter to the PTT socket on the amp and measure the voltage then switch to
