Leigh, Good News, you will really like the hfpack amp with the KX1, this is a super combination that is high on output and easy on the batteries. I recommend using the internal batteries to drive the amp at 20 watts on 40 as it is a very effective power level with a poor ground mounted antenna. As Leigh knows, the KX1 does quite well from a city park picnic table using a Buddistick antenna and a couple of radials.
Super stuff!!!! Regards, Bill K6ACJ
