P3 not communication through RS232 cable

My Pc has the svga installed when I put the kit together but I do not have a
monitor installed for svga yet. I originally was able to download the
firmware using the usb a/b cable and my computer.

The usb a/b cable is now connected to the K3s usb port and using the
lp-bridge for rig control/ logging.

The P3 is seeing signals and waterfall but does not display the VFO A
frequency in the center of P3 display, Instead it show 0 in center and + -
19.5 on each end of display.

The P3 is port connected to the K3s with the RS232 cables included. I cannot
connect to the utilites or Elecraft through the supplied cables.

What am I missing here?

Earl, K4KAY

Make sure the RJ45 connector is snapped into the RS232/P3 RJ45 socket. You should hear a distinctive snap when it is inserted properly.

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

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.

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

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.

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

Re: 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.

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
