Craig, If you are able, try using a real serial port on a desktop computer if you are able - no adapter drivers to confuse the issue. I use a real serial port and have done many firmware upgrades. The only time I had a problem was when I pushed a button during the upgrade process (that was my error, not a K3 error).
If you are confined to your laptop, make sure you have the correct and current drivers for your USB to serial adapter. The older Elecraft KUSB adapters used the prolific chipset, but the newer ones (ordered in the last 6 months or so) use the FTDI chipset which seems to be more stable. The older USB to serial adapters have had some problems with Vista and Win7, so if your OS is not WinXP, and you are using the older KUSB, you may want to purchase an FTDI based adapter. The K3 firmware has been loaded by many users, so that itself is not the likely problem. USB adapters and their drivers are the most common causes of failure. 73, Don W3FPR On 2/5/2011 9:28 PM, cr...@thephotoman.com wrote: > > -------- Original Message -------- > Subject: K3 Failed DSP Firmware Download > Date: Sat, 05 Feb 2011 18:21:05 -0800 > From: cr...@thephotoman.com<cr...@thephotoman.com> > To: elecraft@mailman.qth.net > > > > I hope someone can help me as I tried to update the firmware onto my K3 > this afternoon.
