Just need the problem sorted with HRD and I'll be a happy ham ;-)
Over the past several years, I have been using the Fldigi applications for Digital, CW, and RTTY with my Flex 5000A and now the Flex 6500. Recently I upgraded to Fldigi v3.21.80 which includes the Flex SmartSDR.xml initialization file.
In addition, I run the Fldigi DXCLUSTER application with Fldig. No problems thanks to the Flex and Fldigi team..
Approximately, Four years I started working on LOTW DXCC for each individual HF band using the Flex 5000A and last year switching to the Flex 6500. To date, I need five more 10 meter DX countries confirmed on LOTW which will complete my LOTW DXCC on each 7 individual HF Bands.
I also had the laggy xmit problem in HRD too. Part of trouble I had with trying different versions of HRD to get around the radio name problem involved HRD Logbook not starting. But when the logbook didnt start, the xmit problem didnt exist either. When I rolled back to the lastest (non-beta) version, on a whim, I tried connecting the logbook to the HRD TCP port on DDutil and DM780 to HRD's TCP port... like magic all was well. No lag at all going into or out of xmit. I concluded it was some strange interaction between the logbook and DM780 when both were connected directly to HRD's TCP port a lot of traffic was being generated between them.
I've also seen some really ugly PSK waveforms on xmit. Shutting down and restarting DAX fixes that one right up. No need to shut down DM780.
I run all of my ham software in virtual machines hosted by ESXi. The only (reasonable) way to connect to the VMs is through RDP. This creates some interesting soundcard issues... like there isnt one. When connecting it's important to tell RDP to "leave sounds at the server" otherwise windows will disable all sound cards except for the virtual one that RDP install when connected. Without a sound card, Windows find whatever looks like a sound card (DAX) and make it the default audio device. DAX doesnt like that much. The fix was our old friend VAC. I made a virtual sound card connected to nothing and set it as the default audio device. It turns out that having this VAC in place makes Skype useful for listening to DAX, it's just too bad that those fancy mixing controls all over the SmartSDR UI cant be used to control the audio going to a DAX channel.
Now speaking of video cards messing with the audio, I have seen something similar. My windows machines dont have video cards, just the RDP video driver. But, I can believe there's a connection. If I'm connected remotely to my SmartSDR machine via a really really bad internet connection, I cant transmit or receive digimodes. This just sounds crazy to me (but I'm happy to blame Microsoft) because the audio never leaves the remote machine. There seems to be some sort of synchronization between the audio and the display driver... if windows cant update my remote display quickly enough because of the poor connection, the audio (which never leaves the remote computer, BTW) suffers. Crazy sure, but reproducible... from a poorly connected remote location just display four panadapters and a large DM780 with a fast update rate and see if DM780 can still decode anything. The same test on my home LAN works fine.
Crazier still is that I too exchanged some PSK encoded bytes with the United Arab Emirates this morning!
Tim - W9KXQ and anyone else that is interested.
I 've tried Fldigi and various other programs throughout the years and I found that they all have some quirk to get them operating the way you want. However, the simple fact is that it has the software that I like to use in one package. I do not need to download software from other location and then configure it and hope that it works.
I have stuck it out and HRD is functioning well and to my liking. If you have not downloaded their latest version 18.104.22.168 released 04/15/2014; do. It's more stable and has solve several issues with SmartSDR. I have been running for several days continuously with no failure or hiccup's.
I been told that Flex is working with HRD but I have no confirmation from either side to be true. Flex seems to be favoring Fldigi but that is only my opinion.
I am not experiencing lag in band change, it seems to be better than previous versions. How many monitors are you using? The reason I asked is as follow:
When I was using 2 monitors running SmartSDR, CAT, DAX plus HRD, DM780, Rotor and JT65 beside all the Win7 software etc.. That combination was running slow and HRD, JT65 would change bands the programs would close or Smart software would not remain open. I added a third monitor and it became like night and day. Worked well but the open software had to be minimized. Each had their own real estate with nothing underneath.
Since them everything has worked perfectly fast and no more problems.
These setup works well for me.
This monitor I use for IE, email, or whatever by shrinking the size of JT65/9
Incidentally Hrd closed my support ticket and said open another when Greg gets back to me as he was trying to find the problem so that is still ongoing .
Anyway time for work and then the Easter Break...
