I have tried to install the latest RMS express on a Dell Desktop also running SmartSDR, I followed the steps provided by Tim of FlexRadio. Under device manager I see COM105 and Com5 as the Virtual Serial ports. I assigned Com105 to the Radio Control Port/ serial port and PTT Port/Serial Port to Com 5. In the SmartCat the Serial Com 5 is RMS Express and there is no Com 105. When I open the session in Winlink/Winmor and hit start it tries to connect and SendID and the Winmor Sound card displays the receive levels but no transmit. After calling out a station it fails to connect. Can someone please tell me what is wrong, when I hit the test transmit tone, there is no transmit tone like I saw in the video. The SmartSDR 2.9 version also takes a while to bootup on my Dell PC and show the connect bar to my Flex6600 radio. The PC is directly connected via Ethernet to the radio and sometimes I have to reboot the computer, it seems to show the Radio connect option intermittently.

Hi Arvind,
Here is a screen shot of my set up for ARDOP. Winmor & Pactor would be similar. Once the ARDOP TNC window launches, you can test Tx using one of several available methods, including CWID.
I use a 6600M with an I7 Win10 Dell laptop, and have no latency, slow-load, or other issues. The PC-CPU runs at about 25%. If I can help with anything specific just give a shout. Good luck!

Dudley, can you post a photo of what you mean by "Then you still have not enabled it in SmartSDR console window, the “TX Stack” , to the right of “Mic Gain” slider" In the SDR Console window up top I think currently it is RED is that in Transmit mode. Is that what you mean.

Your DAX is recognized in your second photo (Process = RMS Express) - which is good. I can't see
you're entire CAT screen - do you have a P-com (PTT) to key the radio?
Two additional suggestions I would make: 1) adjust slice A Rx gain higher until it is 25-50% across the TNC receive level (make sure you're computer sound devise is at 100%) and, 2) do not enable DTR on either port - I've found that enabling this will halt all coms (on my set-up anyway).

Jim, Thanks, I'm linking a video on the entire start to stop process and when it goes to connect failure at the far end station, I will post the SDRCAT screen next. I do have a PTT on the radio does that need to be removed/disabled? I think I tried to move that receiver gain on the DAXCat window will try again and will check the Winmor TNC window and will make sure the computer sound is 100%. Where do you disable DTR?

Jim, I did change the port to Com5 and 6 photo shows the incorrect ports.

Not sure but you may be over-driving your Tx - mine hits about 50% max on each call. You may need to "season to taste". Give that a try.
Also, your Tx button is yellow? Mine is blue.
I assume this is a station you have connected to before. I noticed the "quality" is zero (0). I usually don't attempt stations that are less then 50.

I will drop the Tx drive, not sure why the color is yellow, maybe someone from Flex Radio can tell me why that is so, is that got to do with my color choice in the settings. Hmmmm I will have to go and check the Quality, I thought the path was good but I see the quality should be what I need to verify.

Hi,
I think you have to set your PTT port in
CAT so it is the PTT port. Look at my CAT
setup and you can see the CAT protocol for
COM 5 is set to P for push to talk.

I do have Com5 in my setup set to PTT. The photo above shows 105 but I changed it based also on the Port assignment in MS Device manager. You said disable DTR above but your photo shows it is enabled?

Jim, Ahh...the Letter "P" for Push to talk in SmartSDR CAT how did you change to read "P"?

Hi,
You might be confusing me with the other Jim, WQ2H. I'm N9VC.
You are looking at my setup where I have DTR enabled. It works
for me. When you first create the port from port protocol, the port
protocol is a drop down box as pictured.

Choose PTT and continue. As you see in my configuration
earlier, my radio control port is COM 4 for frequency control
and the PTT is COM 5. You need 2 ports, one for rig control
and one for PTT.

Jim, N9VC, sorry for the confusion and thank you for the setup info I'll try that. Right now my bigger problem is my Fkex 6600 does not always give me a connect option when I start it.

I have made all the changes suggested, I cannot edit and change the SDRcat settings com6 set to PTT to read P instead of C, there is no drop down in that window the CAT is greyed out. The SDR DAx TX button is yellow but I do see the TX display indicator red changing. There is no TX power on to the antenna cable as there is no RF carrier in the spectral display. It looks like the DAX is not connecting with the radio transmitter. Is there another setting I could use in Winmor radio setting, the DAX setting don't seem to work. I'm going to try another computer, this is really frustrating!

Delete just COM 6 in the cat control and then click add to make a
new one and choosing PTT in the cat protocol drop down.

Then your box below should look like that, of course with COM 6
in the client com.
In my setup, I use 4 and 5, where in yours, you are using 6 and 7.
Of course save the config.

Jim, Thank you I think I understand the CAT which is frequency control which works on mine as I have the DAX in receiver slice A turned on. I now understand the TX DAX and that is the DAX in the Mic control under ACC. I will make that change tomorrow and that should get it to work to TX out with your suggested PTT change.

That's great Arvind. The 6600 is a great radio and there is clearly plenty to learn! Glad to hear it's coming together - best of luck to you !
