Re: Emailing: k3fw4r47.zip

Ok , well I did exactly what you are looking at doing yesterday.

Basically just extract the zip file to a folder location on your pc .
Then use your ''browse'' in P3 utility under firmware tab to locate that
folder.

Ensure the menu advanced function is active so you can select which files
will be sent to the P3.
The right side column will show the older firmware checked (in checkbox)
files against the left column
existing new files you have loaded.

Use the send checked files to K3 (These should already be checked by
default) to K3, and it will go through a firmware downgrade .
Then you are good to go.

If you do get a mcu ld error with tx light on, then unplug the APP connector
power in for a minute & close port on P3 Utility.
Then (after a minute) power on holding power button in for 10 seconds until
TX ind flashes.

Screen will be unlit with mcu ld visible. Close port on P3 Utility, a
"firmware required" popup should occur and you can redo the firmware
downgrade as previous. Then you are good to go with a good decoder.

Adrian, that's exactly what I wanted to do as I am using the new P3 digital
modes and find the decoding is not up to par.

However, the K3 utility wants to only go up in firmware so I am not sure
how to get it to recognize an older version for installation.

I got into trouble earlier and it took me three hours to reboot my K3 as it
went dead, I was trying to intall 4.50 at the time and could not get the
utility to recognize it.

I wasted a lot of time on that one.

This is 4.47, if you are just look to restore good K3 decoder etc.

Cheers

Adrian

I have successfully downloaded 4.47 after crashing the radio once but came
back according to your input and 4.47 loaded in.

Disconnecting the P3 before K3 power up, after a mcu ld issue is required
and I forgot to mention that. Plug P3 supply back after the K3 firmware has
been completed. Sounds like you were good, but I just remembered that.

Now, I am wondering what settings you have in your rig which gives you
really good decode. I am working on that now. I have the AGC threshold set
to 8 with the SLP set to 7.

Set SLP to 0. AGC at 8 is good.

I have theTEXT DEC set to threshold of 5 and 30 to 90 wpm.

Yes the 30-90wpm works the best even at slow speeds. I use a narrow filter.
Set threshold for clean pulses on the cwt display after spotting (centre)
the signal. Then use filter width and/or rf gain to fine tune. I get perfect
results most of the time, and using this method on noisy lower bands works
well.
Just check the cwt is pulsing with the cw, then you are close. The fine tune
is reflected in the print.

I just noticed my P3 cursor will not move so have another issue HI> Check
for tracking mode or disable re-enable svga etc.

Good Luck

Re: Emailing: k3fw4r47.zip

Sooner or later running a K3 with back level firmware will be a problem.
With so many devices coming out and the amount of work on those, you will
simply be left behind. No company without the economies of scale like
Microsoft can maintain old code.

Some people report getting perfect copy using 4.51. Can they please share
the AGC settings, and decoder threshold, etc that they are using. Please
include any NB, NR, bandwidth, RF gain, etc. settings you are using.

Knowing the perverse nature of CPU coding for hardware, it's entirely
possible that the 4.47 "good menu settings" depended on an AGC bug in 4.47.
That would mean that it's impossible to restore the settings from 4.47 in
a future 4.52.

I seem to remember a period of thrashing about when CW decode first came
out, until working popular settings emerged.

73, Guy.

Re: Emailing: k3fw4r47.zip

Guy, well Elecraft said they acknowledge the issue and they will work on
it in the next firmware. When that happens I will pick it up.
Of course with 4.51 you can get perfect copy in perfect conds, but try a
very weak signal or a noisy background and you are doomed.
The cwt threshold point dropped from 8 to 2 with the new firmware
leaving little to work with.
I consider myself pretty good at setting cwt and have trained a few k3
owners in this area to the finer points using RF gain and filter width
to get it near perfect, once the threshold is set.
