Over the weekend I was able to get my sub-entry level rig on to HF digital modes, specifically FT8. Among other little things I needed to do, I made an audio cable that connected the laptop soundcard out to the µB's stock mic in, without connecting the PTT. Another regular AUX cable went from the laptop line in to the headphone jack on the µB. Ian Lee KD8CEC's µBITX software includes FT-817 emulation for CAT control in WSJT-X; see http://www.hamskey.com/2018/01/wjst-x-configuration-for-ubitx.html; that was just a USB cable to the Raduino. I did not need any additional interfaces like soundcards or Easy Digi. When I was tuning it up, I could verify that the µB was not being overdriven by watching the signal on the RSP1a/SDRuno. It worked, and now I have a few QSOs in my Zed logbook. I wish I would have written down a few of the DX callsigns I saw calling CQ; I remember they started with H, I, and T. It was very interesting to watch the propagation come and go.
