K3: K3 Utility v. 1.1.4.1 Question

[Joel R. Hallas]

Folks,

I just successfully uploaded the new firmware, and especially appreciate the
"absolute S-meter" option--makes perfect sense to me!

I just noticed something on the utility main page that puzzled me. Not sure
if this was on earlier versions, but there is a check box on the utility
main page that says "Always load DSP data tables."

I have had it unchecked, must be the default, and it was this time as well.
There is nothing about it in the "Help" index (that I can find). Does anyone
know the correct setting? Under what conditions would I want to, or not want
to, load DSP tables?

Thanks much!

Regards, Joel

The K3 Utility Help describes this on the "Firmware" tab:

Always load DSP data tables

(Advanced Mode only, intended for firmware developers) DSP1 and DSP2
firmware consists of program instructions and some large data tables. Each
DSP firmware revision will change the program instructions, but the DSP data
tables are expected to change less frequently. DSP data tables are normally
sent to the K3 only when a new DSP data table version becomes available.
This reduces the DSP firmware load time. The Always load data tables check
box causes the DSP data table to be loaded whenever the DSP is loaded,
without regard to the currently installed DSP data table version.

Users that aren't DSP firmware developers probably never need to select this
checkbox, but if you do, it will just take more time to load the DSP when
you select the "Load" checkbox on the DSP1 or DSP2 row. Nothing bad will
happen if you check the check box.

Just, FYI, my K3 had a *very loud* noise on initial power-on and also when filter bandwidth was reduced to 500 Hz.  After some discussion with tech support, they suggested loading the DSP data tables which instantly fixed the problem.  So, it seems that sometimes/somehow these table can become corrupted or out of sync.  Since then I've left this box checked and haven't noticed any significant difference in download time to the radio.
