I just had an issue installing the Beta firmware (3.97 - 2.58) on my K3. The first 2 times I tried, the DSP load failed on both 1 & 2. As I just installed a new RS232 card in my computer (my USB-232 converter scheme was quite noisy) I assumed something was wrong with the new set-up. I went in and checked all the settings on the computer and K3. A-OK so I tried again. This time DSP 1 loaded OK but DSP 2 failed again. I re-checked my new RS232 set-up and it works great with HRD and the Elecraft utility (I used to get noise when the utility polled the K3), noise issue completely gone.
I tried again after setting the I/O buffers a bit lower on the computer port settings, no joy. As this last attempt was in progress I noticed the S meter was very busy. After it was done (failed), I turned the RF gain (and AF gain) all the way down and tried once more. Bingo!
Anybody else ever notice this?
