Recently I have taken up mobile operations again. I use a FT-857D at 5w and an ATAS-100 antenna. My external loudspeaker is not very good so tonight I tested the Heil Traveler Single sided headset. I worked EG5CI on 17m, UR5IFB on 20m and LA1BNA on 10m. So far I have worked CT9, E7, S5, UA4, 9A, 5B, LA, I, UR and EA on SSB QRP from the car this year.
The ATAS antenna is mounted on triple magnet base but I'm not really happy with this solution. I have tried to find a SO-239 antenna mount for roof rails suitable for HF antennas. Any suggestions? I use a counterpoise magnet mat as antenna ground.
