Some progress.. 1. The BFO setting for the R bar mode was set incorrectly, resulting in a dsb-like transmission. The 't' in the filter settings really does mean that the FL1 BFO is used for transmitting.
2. The power levels were within 1 watt at 20 or 30 watts via a DL2 measurement scheme. No change made. 3. R98 was adjusted going up to 1400 ohm before 10 meter levels reduced a bit. R98 was set to 1100 ohms. The variance at 7.073 MHz for a 5 W power setting was improved. But .. K2 at 5 W and KAT-100 perform nicely in digital modes. With the KPA and a power level of 40W, with the KAT into a dummy load the rig works nicely, too. With the antenna tuned by the KAT automatically to 1:1 SWR, the ALC level display changes to 1 bar and the RF output level shows more motion. The signal, by reports, still distorted. During transmission (Olivia 8/500) I can hear a weak version of the transmitted signal on the speaker or headphones. Suppose the KAT isn't really matching the antenna and the 1:1 SWR reading is false. Would that cause the ALC/RF output effects? -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-KPA-ALC-problem-tp7581353p7581686.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
