6400M RMS Express WINMOR TX Problem

  • Problem
  • Updated 4 months ago
Flex 6400M with V2.4.9.45 software. CAT and DAX installed on Windows 10.

I have been unable to get any RF power out when trying to make WINMOR connection with RMS Express. The radio goes into transmit mode but there is no power out indicated and I do not get a connect.

I am fairly certain the basics are setup correctly. I do not have any trouble using FLDIGI for other digital modes such as RTTY, PSK31, FT8, etc.

Any tips on what to check or links to a tutorial that references the V2.x.x.x software, etc. would be appreciated.

These are the settings I use for transmit and receive.
You say it goes into transmit, but no power output.
I have been using this for years with my Flex. If after
you compare and make any changes, please post some
screen shots as it is hard to guess where your set up
might have went wrong.

Tim, Here is my setup and works every time, except I found during the really smoky days here in San Francisco Bay Area, I could not connect.  Looked like lot of charged particles in the smoke which did not allow me to connect.

Tim,  I used Jim N9VC's setup and it works, looks like he posted lot more details follow all the steps and it should work.

Tim, Make sure that DAX on that panel to the right and the one on the flag on the top of the spectral display is highlighted and Blue.  On the DAX panel it should also be Blue, otherwise you will not see the transmit spectral output on the display like I have shown.

Thank you everyone. The 6400M is working perfectly with Winlink Express now.

I compared my configuration to those posted by Arvind and Jim N9VC. I did not see any difference. I deleted and re-entered every parameter and it is transmitting as expected now. I'm not certain what was different but I imagine it was something I had done incorrectly.

I'm seeing a new but related problem with Winlink Express when using WINMOR or Ardop and my Flex-6400M.

My PC is running Windows 10 Pro on the same network as the Flex-6400M. Winlink Express is up to date and I'm using the current version of the Flex software.

Recently when I try to connect to a station I see a message on the modem UI that reads "Timeout in T>R latency measurement". When this occurs I can never connect to an RMS.

Anyone have any pointers to what settings effect this? I'm not 100% sure what this refers to although I believe it's related to the time between when Winlink Express tells the radio to transmit and when the Flex-6400 receives the command and goes into TX mode.

Thanks for any insight.

Hi Tim

I had the same problem in that the radio was keying at the wrong time.
I found that my Smartcat PTT port RTS and Polarity needed to be set to Low.

Hope this helps.

In addition to my Winlink problem I also discovered on SSB that the radio was not transmitting as soon as I pressed the mic button. I was trying to work another station and they could not hear the start of any transmission.

I ended up doing the reset procedure for the radio and now everything seems to be working fine. Some little config file must have gotten buggered up somewhere along the line.
