[Elecraft] K4 Data Mode Questions

[rocketnj at gmail.com]

I'll answer #2 first - if WSJT-X is set to Data/Pkt (which it should) in setup/radio then yes, the radio will switch to DATA

#1 - I am guessing you are using the USB cable to PC for sound? Check Windows Line USB Audio CODEC and make sure level in Windows is 100. Then on radio tap TX and Line IN. Make sure it is set to sound card and I have my level at 32 to give 5 bars when I click the TUNE button in WSJT-X. I also have power slider in WSJT-X all the way up.

Hope this helps!

Subject: [Elecraft] K4 Data Mode Questions

Two questions on using my new K4D for data mode, specifically, FT8.

First, with both VFOs set to DATA mode, no matter what I do I am only able to get two bars on the ALC meter. I read in the operator’s guide that I should keep it under the “5” mark. On my K3, I always kept four solid bars and the 5th flickering. Obviously two bars is waaaay under that “5” mark, but why, when I advance the MIC level from 1 all the way to max, does the ALC meter only stay at two bars? I am able to make contacts on FT8 so the thing is working, but I’m puzzled. Should I be able to get more than two bars of ALC in DATA mode?

Second - the K4 seems to think for itself. After scratching my head regarding that ALC level issue, I decided to try using USB mode. I put both VFOs into USB and…… this sneaky radio automatically switched both of ‘em back to DATA mode as soon as I transmitted. Is that normal / expected?
