C'mon guys, I cannot here that "it's like a computer" argument anymore! ALL modern transceivers nowadays are controlled by microprocessors and ALL get it right to be on the same QRG after a power failure ... except our beloved K3!
The last used frequency is stored into the EEPROM of the PIC (or probably external memory, haven't checked the schematics on that) when changing bands so why not already save it after no move of the VFO knob of say 5 seconds? The only valid reason not to do so that I could see (it can't be programming as the function is already there) but still struggle a bit accepting (as others do get it right) is the "fear" of memory failures within the rig's "lifetime" as you usually can only write into EEPROM (at least that in today's PIC processors) for about 1.000.000 times and that's not much depending on usuage scenarios and storing the frequency e.g. all 5 seconds. Is that the real reason why not implementing that easy functionality, Wayne? 73, Olli - DH8BQA - K3 #4546 http://www.dh8bqa.de ----- Original Message ----- From: "Ron D'Eau Claire" <r...@cobi.biz> To: "'Dave Anderson, K4SV'" <davek...@yahoo.com>; "'Elecraft'" <elecraft@mailman.qth.net> Sent: Monday, February 28, 2011 5:39 AM Subject: Re: [Elecraft] My K3 forgets where it's at on DC failure > The K3 is controlled by a microprocessor, so it behaves exactly like any > computer when power is suddenly removed without allowing for normal > shutdown. > > One of the most benign reactions is that it forgets the last frequency used. > > > Just like a computer, the effects can be a bit worse, requiring reloading > the firmware. > > Ron AC7AC > > -----Original Message----- > From: elecraft-boun...@mailman.qth.net > [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Dave Anderson, K4SV > Sent: Sunday, February 27, 2011 8:23 PM > To: Elecraft > Subject: [Elecraft] My K3 forgets where it's at on DC failure > > Hi All, > > I am back from the TJ9PF DXpedition where I brouhgt my new K3 to use for the > 6th > station.
