I am trying to do my first firmware upgrade of the K3 but am unsuccessful at getting it installed.
I am using the USB to 9 pin rig cable. I downloaded the Elecraft K3 Utility last night plus I've downloaded the latest drivers from the Prolific website. While I was successful getting the Elecraft K3 firmware onto my computer, I am not able to get it onto the K3. I have listed some things that may help someone understand where I am stuck at and help me get the firmware onto my K3. I apologize for this being so long, but I'd rather not leave anything important out so someone can recognize what's missing. Per the instructions in Elecraft KUSB USB to Serial Adapter looking in Device Manager and then under Ports, the Prolific USB to Serial Comm Port is COM 5 The DRIVER Tab for the Prolific USB to Serial Comm Port Properties says that I have the latest version 2.0.2.8 Under Port Settings of the same Comm Port Properties this is what it says - Bits per second 9600 Data Bits 8 Parity None Stop Bits 1 Flow Control None If I click the ADVANCED Tab in the above, it lets me change the Com Port #.It is still at 5 right now - the default. On the K3, going to CONFIG then FW REVS sub menu it says my CURRENT FIRMWARE installed is 01.69. When I used the Elecraft K3 Utility to get firmware from the Elecraft website the first time it downloaded 7 files onto my computer. Then I tried it later and it said it copied 1 file from Elecraft. Also on the K3 Utility it stated, "K3 Boot Loader is ready for MCU Firmware load, RS232 38400 bps" I got this message twice in a row. I am still getting the message "MCU programming failed. Verify file source and version" "Turn the K3 off and back on, then re-try the firmware load" Looking at the PORT tab of the K3 Utility and doing a test communications for Port 5 - which is the port that the Prolific driver says it's using I get - "K3 is running main program, RS232 4800 bps" If I try port 4 I get " K3 boot loader is ready for MCU firmware load. RS232 38400 bps." Because of the two BPS rates above and the different BPS rate for the Prolific USB driver, should I change my bps in my driver settings or elsewhere? Also, I haven't saved any configurations in the K3 Utility software. Should I, once I get things working? So it looks like I keep running into the same stumbling block, I feel like a bit of a thick head that I don't know why this isn't working. I would appreciate help in getting the firmware installed on the K3.
