Re: [Elecraft] K3 Filter Settings Main and Sub Receiver Track For Data Mode Only

[Mike K2MK]

Hi Elliott,

I tested MCU 5.33 and could not duplicate your problem. I noticed that the
latest production release firmware is 5.38. I loaded 5.38 and again tested
and still could not duplicate your problem. So maybe the problem was only
present with MCU 5.35.

Another possibility is that you accidentally put the K3 into Diversity mode.
In diversity the Sub RX filters are always the same as the Main RX filters.
A quick test is to press BSET and then press XFIL. If the word "=MAIN"
appears in the lower display then you are in diversity.

[Elecraft] K3 Filter Settings Main and Sub Receiver Track For Data Mode Only

[Elliott Lawrence]

Using the latest K3 firmware MCU 5.35 for my K3 (not K3S). In the Data mode 
only, setting the bandwidth of the main receiver also causes the subreceiver 
bandwidth to track and be identical. The BSET control XFIL for Data has no 
effect.  In CW and SSB modes the main receiver XFIL can be adjusted and the 
subreceiver XFIL changed independently using BSET.  This was definitely not the 
case for previous firmware versions.   This operation is not band dependent.

I have checked all of  the firmware notes and the latest K3S manual and can’t 
find anything to explain this operation.  Am I missing something?  Is this a 
new and unwanted improvement?

Thanks for your comments.

Changing to MCU 5.38 did not solve the problem.  Need to contact K3 support!

Re: [Elecraft] K3 Filter Settings Main and Sub Receiver Track For Data Mode Only

Hi Elliott,

Here's a long-shot. Take a look at your filter selection for your SUB RX
using the K3 Utility program. Maybe you only have one filter enabled for
DATA mode.

Re: [Elecraft] K3 Filter Settings Main and Sub Receiver Track For Data Mode Only

[Guy Olinger K2AV]

I have a K3. Did not have the problem in 5.33. Do not have the problem in
5.38. I am unable to duplicate your problem. In Data A, and b SEt width
control varies width in sub RX while main RX stays the same.

Your report sounds like you are in diversity mode. My frequency shows as
1.814.9 The right decimal point is blinking. Is your right decimal point in
the VFO A display blinking?

I have not had bench time to install the KSYN3A mods. What is your status
with the SYN mods?

73, Guy
