[Elecraft] K3/P3 Question about Bandwidth display on P3

[tomb18]

HiThe command you are using to change the bandwidth is incorrect. It isBWXXXX; not BWXXXXX;You supply bandwidth in 10hz increments. Thus for 300hz you issue BW0030;This is likely the source of your error.I have a bit of experience in programming the K3 and I have found only 4 bugs, that's it. Whether they are bugs or the documentation in wrong is debatable. But the BWXXXX command isn't in error.73 Tomva2fsq.com

Hello,

I just noticed what may be a bug in the L3/P3 software.

Setup:
1.  Using the K3/P3 combination

2.  Using a macro to change bandwidth launched from the P3, via the 
Elecraft Utility program.

3.  P3 set up to show bandwidth by making the cursor line running 
vertically wider of narrower.

What happens:
While in CW, or SSB, (no other modes tested), if I am at 2.4 KHz 
bandwidth, (and the P3 is showing the correct BW on the screen via the 
width of the cursor), and I initiate a BW change using the Macro Editor 
utility Elecraft provides, using the macro command, "BW00300;", the 
bandwidth changes on the K3, but the display of bandwidth on the P3 does 
not change width.

If I then manually turn the BW control on the K3, no matter how small a 
change, the bandwidth on the P3 then instantly reverts to correctly 
showing the bandwidth.

An example...  I set the bandwidth via the K3, and the bandwidth updates 
fine on the P3, and K3.

I then unleash a single macro as described above, (from the P3 utility 
program), the K3 changes bandwidth correctly, but the P3 does not 
indicate the change, by changing the display cursor width.

If I then launch more BW changing macros of the form BWXXXXX;, from the 
P3 Utility, or from my Genovation Keypad, no changes are shown on the 
P3, with regards to width, while the K3 always goes to the specified 
bandwidth correctly.

If I then just touch the BW knob on the K3 only enough to trigger the 
encoder, (any change, no matter how small) the P3 reverts to the correct 
BW display width.

Discussion:
Has anyone else seen this behavior?  I am pretty sure that when I 
created all of the BW macros for my Genovation keypad, this was not 
happening.  So I think this happened sometime in the last year.

I noticed this while changing bandwidths using my Genovation keypad 
today demoing the K3/P3 to a friend.  I then removed all of the 
Genovation items, and tested again, the problem persists, so it is NOT 
the Genovation keypad.

I suspect this is a bug and will need to be addressed by Elecraft.
