Mine does the same thing all the time, so much that I do not like to using the tuner any longer. I confirmed it was tuner in the amp by operating into a dummy load. Its does it into the dummy load on CW and SSB. I have not said anything, thinking an update will be pushed out and the problem will disappear. In the meantime I use the KAT500. Its all to frustrating to be in a QSO and have it act up. It kind of behaves like the KAT500 did before they upgraded the firmware. I am sure they will get around to taking care of it.
73, Dan KM6CQ I've run into several occasions where in mid-CW transmission my KXPA100 (with internal tuner) SWR takes a momentary jump from matched to maybe 3:1. I see the SWR jump on both the KXPA front panel LEDs and on the KX3 VSWR display. It lasts for maybe half a second, I hear several clicks of the relays in the tuner, and them it's back to normal. When normal the SWR is pretty much 1:1 on the KX3, and the second green LED lit on the KX3. I've not seen it happen at the start of a transmission, but rather several characters into a CQ or exchange.. In the ARRL 160 contest Saturday night this was happening perhaps once every 2-3 minutes. I'm using a fairly well matched antenna - not random wires. I also encountered this problem on 15 meters when operating from W1AW/8 in WV in October. In both cases I was running a pretty high CW duty cycle while running at a pretty good clip. The amp was warm, but the heat sink air flow is not blocked. Any thoughts? 73 - Jim K8MR -- KM6CQ Dan Baker www.km6cq.com @danielbaker DM09dn SKCC: 8260 NAQCC: 6817 QSL via LoTW, eQSL, & Direct.
