Re: [Elecraft_K3] Unable to Update K3 firmware

dalej <dj2001x@...>


I just downloaded both the latest Mac utility and the latest K3 firmware and it installed without a problem. I'm using (Mac OS 10.8.5)

Try downloading a fresh file from Elecraft, maybe it got damaged somehow. Also the cable, are you sure it's connected in the back, sometimes if they're not secured can drop out.

I am using a mac with Mac K3 Utility version

Here is the firmware I have installed in my K3, as well as what I am trying to upgrade to:

MCU 05.14 trying to upgrade to 05.29

FPF 01.19 trying to upgrade to 01.22

DSP1 02.83 No Change

DSP2 02.83 No Change

Prior firmware upgrade of my K3 have all worked flawlessly.

Any suggestions on what I might be doing wrong?

Thanks and 73,
