More experimenting this afternoon... I am pretty sure now that it is the switch itself. If I do a press and hold (as if it had one of those famous hold functions) then the switch operates just fine. No problems. But, if I press as pressing a normal switch like I do a hundred times a day on the Elecraft gear (OK, maybe 30 times a day) then at times (more than half) the switch bounces back.
But, it is strange that this behavior started right after I upgraded firmware to 1.63. I mean, the entire time I have had the KAT500 I have not had a problem with this switch until after the upgrade. So, if I were to assume wild things I could assume that the timing has changed a little bit on these button pushes. Maybe the software used to detect a button press faster than it does now or something like that. Not sure. But, the other antenna LED does briefly flash on before it bounces back. So, maybe it is a physical problem with a double hit on the switch itself. Just wild guesses here. I have done some PIC coding before with switch sensing so I understand that this could be an issue but then again, maybe just a funky switch. 73, phil, K7PEH On Apr 13, 2014, at 4:15 PM, Cady, Fred <[email protected]> wrote: > Not seeing it here, Phil. > KAT firmware 1.63 > 73, > Fred KE7X > > >> -----Original Message----- >> From: [email protected] [mailto:elecraft- >> [email protected]] On Behalf Of Phil Hystad >> Sent: Sunday, April 13, 2014 3:02 PM >> To: Elecraft >> Subject: [Elecraft] KAT500 Problem --- switching antennas >> >> Ever since the most recent KAT500/KPA500 firmware updates, switching >> between antenna 1 and 2 shows funny behavior. >> >> For example, on the 20 meter band I have two antennas: >> >> Antenna #1 -- Wire 80-meter Dipole (ladder line fed) >> >> Antenna #2 -- Hex beam >> >> So, I am positioned on antenna #2 for 20 meters.
