Filter setting changing with modes and LP pan software

I have been noticing that sometimes if I cycle through the modes on the K3 from USB back through to USB (including cw, data, AM, FM and back to USB) or turn on either Power SDR or Na3p my filter settings change and sometimes considerably. This can happen if I stay within the same band or when I change bands.

It does not usually bother me too much but it is starting to concern me a little. Is there some type of setting that I need to lock in so as I change mode the filter settings remain constant. I would think it should resort back to the previous or last setting I was at when I return to the mode and should not change just because I turn on Na3p. Any thoughts on this would be great.

Re: Filter setting changing with modes and LP pan software

Unfortunately, NaP3 sets filter widths (high/low cut) on the K3
when changing modes rather than simply follow the values as set
on the K3.

There is nothing that can be done about that unless the author of
NaP3 provides an option to *not* set filter (high/Low cut) on the
K3 and simply follow (display) the K3 settings.

Re: Filter setting changing with modes and LP pan software

Joe,

Thanks for answering my question so quickly. So even though this is annoying it is normal and not a malfunction of the K3.

Thanks,

Keith

Keith, did you turn off "Poll Filter Width" on the front page of NaP3 setup?

Tony,

I will need to check that setting again but I thought I did. When I get down to the shack I will check first thing.

Re: Filter setting changing with modes and LP pan software

Keith,

I think you'll find that it is NaP3 that is doing this. NaP3 has default
filter settings for each mode and restores those filter settings every
time you change modes. This happens regardless of whether the mode
change is initiated from NaP3, from the radio, or from other control
software.

If all you want is panadapter software without the radio control
features of NaP3 (for example, if you are using another radio control
program such as DXLabs Commander), you might want to investigate using a
panadapter program that does not change radio settings other than the
frequency, such as TRX-Pan.

You will have to turn off CAT Polling for both "Filter Width" and
"Filter Shift" in the NaP3 Setup. Doing this stops NaP3 from changing
the filter settings on mode changes, but it also disables filter control
from NaP3, and (understandably, since polling is disabled) the filter
display on the NaP3 spectrum display no longer has any relationship to
the actual filter settings on the K3.

What is really needed is a way to disable the automated filter control
that takes place on mode changes but without disabling polling and
manual control of filter settings.

Re: K3 Filter setting changing with modes and LP pan software

In reply to this post by Keith Heimbold

GM Keith: Notwithstanding Joe's comments related to Na3p, I've noticed a K3
software "memory" problem which may or may not be related.

There seems to be two instances of when the K3 appears to "loose its mind".
(BTW its s/n 2432 using 4.47 and 2.73 FW.)

1st is when I've set up the Norm I and II for specific settings in CW and
SSB modes and as I cycle through various bands and / or power cycles, it may
or may not return the the Fltr & width that I had set for Norm I and Norm
II. I can't tie the problem down to a specific sequence of key strokes. At
one time I thought it appeared more in CW and SSB modes rather than Data
(FSK D), but now I'm not sure.

2nd is when operating FSK D and set for 45 baud, it will (for no good reason
that I can find) change to 75 baud. The only indication is that RTTY copy
is now garbled. If I go in and change it back to 45 baud, then things are
ok for a while - but I don't know for how long. It happened 4 times during
the recent ARRL RTTY RU contest.

I've related this to K3 Support and was told that it was a known problem and
was on Wayne's list. He has been somewhat busy lately with the new KX3 so
it hasn't worked its way to the top.

===========
Yep, that seems to be what happens. I just use NaP3 as a panadaptor
with point-n-click tuning, with filter polling turned off so I never
noticed the problem Keith experienced. I use the K3 controls for most
things. Of course, sometimes it can be convenient to change bands,
modes or whatever by clicking on the NaP3 display. But if you set it
up so that NaP3 can change filter width, you'll run into what Keith
did.

This is the key - NaP3 should be able to *read* the K3 filter settings
without changing the filter settings. Reading the filter settings are
necessary if one expects the filter highlighting to accurately display
the main rx bandwidth of the K3. Reading the sub rx filter settings
are also necessary to accurately display the sub rx bandwidth *if* the
NaP3 *SUB* mode is engaged.

On the other hand, if one is using NaP3 as a second, third, or even
fourth receiver, NaP3's filter display should probably track the DSP
in NaP3 (PowerSDR) and not that of the K3. It's all "just a bit
complicated!"
