Firmware versions 2.05 and 1.75 do not necessarily support all the same macro commands. If you were loading a macro under v1.75, be aware that it may not be supported with v2.05.
Alternatively, you may need to add a macro under v2.05 depending on tune power level. Just a thought. 73 Lyn, W0LEN -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Bob McGraw Sent: Monday, January 03, 2022 11:24 AM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Problem with KAT500 firmware v. 2.05 Oh I intended to add, I run 20 watts as my TUNE power. Also my other wire antenna, 240 ft center fed with 85 ft of 400 ohm window line terminating to a hybrid 4:1 Guanella current balun and 1:1 Guanella current balun will match every frequency between 160M and 10M. On 6M I bypass the tuner as the internal circuit has a slightly higher SWR than my 4 ele yagi. 73 Bob, K4TAX On 1/3/2022 11:01 AM, Bob McGraw wrote: > I don't find that to be the case with my KAT500.
