Good Evening / Good Morning Wayne,
K3 beta-test firmware revision 2.67 (with DSP rev 1.96)
is now available.
It's always nice to arrive at work and see that a new version of the
firmware is out. Thanks!
I'm afraid I can not describe the following as well as I would like
to, but there are a couple of things which strike me as being a wee
bit strange when using the KRX3.
- The AFV metering displays values are very different from the main
RX, even when the main RX has been "turned off" by reducing RF and AF
gain to minimum values. Some values were very strange e.g. something
like 9950.
- While in BSET mode one can not read the AFV meter. Which makes it
rather awkward to compare the filter losses and set up the gain
corrections.
- It appears to me that the XFIL button does not switch the KRX3
filters unless one is in the BSET mode.
- Is there a method to turn the main RX off, e.g. for doing stuff such
as setting the filter gain correction for the KRX3?
Maybe I'm overlooking something here for the above.
Also, I discovered last Monday that I can still, weakly, hear knob
encoder noises, this time on 50MHz and only (?!?) with an antenna
connected , which strikes me as strange. I'll need to try rearranging
the various KRX3 cables (again). The 50MHz band is not very important
for me personally so I'm not too worried by this and I need to better
understand the exact combination of antenna settings, pre-amp, KRX3
on/off status etc. which enable me to hear/not hear the encoder noise.
It could very well be that with a real 6m band antenna the encoder
noise is below the band noise.
I'm off from work next week, so I can look into the above and send you
better descriptions, if you like. My K3, #67, presently, if I am not
mistaken, either uses firmware version MCU 2.46 / DSP 1.92 or MCU 2.58
/ DSP 1.94, i.e. I missed out on the last couple updates.
