I just a got second hand K2 today and have some questions. For reference the SN is 2289 and it has the 2004 mods. 1. I need to know about the CAL FIL function. I prefer a CW pitch of 400 Hz. The previous owner had it set at 600 Hz. The manual states I might want to use CAL FIL to adjust the BFO settings for a new pitch. The problem I am having is that I can't get the filters to accept a 400 Hz pitch, even when ST P is set to 400. The exception is the 1.5 kHz filter. The 700 Hz filter sort of passes a 400 Hz tone. Since I didn't build the K2, I don't have the frequency counter test cable mentioned in the CAL FIL section, at least I don't think I do. 2. The K2 has the KAT2 internal ATU. I am getting HI CUR warning on an antenna that is already matched. The antenna is a ladder line fed delta loop through an old 275 watt Johnson Matchbox. I know the antenna is matched for the portion I am using. The coax is connected to the ANTENNA BNC instead of ANT1 or ANT2. I tried setting ATU to CALP or CALS. I simply want to bypass the ATU for home use. But I also want to use the internal SWR function to manually tune the Johnson Matchbox. I will try the ANT1 or ANT2 BNC connector. Perhaps that is what I should do. Reading the manual couldn't hurt either, hi. 3. My last question is about the adding KPA100 option. I wish to keep the KAT2 for portable operation. I know the KAT2 and KPA100 options are not compatible. Can I switch between them in a short amount of time? I have heard the top lid can be swapped on the fly to switch between the QRP and 100 watt modes. Is this an easy thing to do? I might want to use the KAT2 in the field and KPA100 at home. Do I have any takers on these questions? 73, Steve N6VL _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
