@ Rich
I would comment on your post if forum were in the UK and I know it would be found amusing - us British are well known for our toilet humour. I am mindful that it is hosted in a country where the name of a female dog and the 4 letter synonym for the underworld are commonly bleeped out. I'll have to keep my dirty mind to myself for risk a ban/censure.

Translation is always a problem. Here in Texas we have to supply those who have unfortunately been exposed to the environment pervading College Station with a conversion chart from MHz to Mc.

Outstanding demonstration. Now if I could just figure out how to use even 10% of the capabilities of the radio. BTW the actor in the demo obviously is making do with advertising spots pending his next Hollywood or Broadway gig. I predict Oscars in his future.

Looks great.  Waiting for WAN here and hope can work about as well.  New remote antenna farm here needs connecting.  73, Carl/K5HK in Reno NV

Looks great.  What impressed me is the reduction of data received while operating the radio.  At 15 fps my receive data is currently 2.7 Mbps for one receive frame open.  If I change the frame refresh rate to 30 fps, the receive data transfered jumps to about 3.5 Mbps.  In the video, the RX rate was 25 Kbps.  This is about one thousandth the data transfer to listen to the radio.  This appears to be set for WAN use in the future.  BTW, if I open 4 receive frames on my Flex 6500, the receive data jumps to about 8.5 Mbps on my current Ethernet connection.  Thanks for the video!

Don, here is the FLEX-6700 running hard wired LAN remote on 8 panadapters and 8 slices.  DAX is also running on one channel to Fldigi (not shown).  Network traffic is only 9 Mbps!  CPU loading is 15% both as shown in lower right corner of the screen shot.  This is the RTTY contest from this weekend.  This is a major improvement in performance over v1.3.8.  The audio is perfect on this setup over the LAN even with 8 receivers.  If you are running WiFi, your results may vary depending on QRM from other WiFi routers in the neighborhood.

James Whiteway

Just curious, what happens if you spread the panafalls over several bands instead of one ( 20 meters)? Would having to handle a broader spectrum of activity create a bigger load and more network traffic? As it is, it appears that being all in the same band it is simply repeating the same thing 8 times. Either way, displaying that much info over the LAN with little loading is impressive.

Sounds ready for release, hi hi.

Jim Bryce W5HFS

Gerald, Thanks for the illustration. Will this reduction to 9 Mbps result only while running in remote, or will a similar low data rate obtain when running in the "standard" mode? If not, then what would one give up by running remote when proximity would allow running "standard?"

looks good to me , publish it

Stick to plan
10  test
20  If no Bugs Then ShipIt
30  fix bugs
40  GoTo 10
50  END

Excellent work by the **** programming staff to pull this much performance out of the system in this amount of time with bug fixes and enhancements thrown at them also.

Many Thanks for the Update.

Tim

PS:  Gerald : Between you and me gave you give ETA as to ship date.  I'm seasoned in the s/w biz to know what E means.

Of course there will be those that maintain you must have 100 Gigabit Ethernet speed for proper SDR performance.

Gerald-K5SDR

James, the number of bands makes no difference.  

Jim, in "standard mode" you are running audio directly to the speakers so there is no impact for that.  Remote is the worst case since I am running 8 streams of audio and video.  

DAX and DAX IQ are full bandwidth since there is no data compression involved.  

Tim, your Basic or is that Fortran program is 100% correct.  Also called a "Do Loop."  We just need a plug for a memory leak.  ;>)

Sometimes maintaining proper overkill percentages, can be a killer. Over and out.

Thanks Gerald,

Here is a screen shot of the current system at my QTH using about 9.1 Mbps.  I am impressed with the improvements.  Thanks for sharing.

@ Burt

Not yet. I have a lot of work to do to get my CW up to a usable speed.

Hi Don, 
How do you get the slices to be side by side? Or is this a new version feature?
Thanks.

I remember the Aggies/SMU Ponies jokes from my time at SMU in the 80's. Worse than the IU/Purdue jokes here in Indiana!

So are the Q codes also used in speech and writing. I bet you use them too ;-).

DH2ID

I am a radio amateur, therefore I use Q-codes and speak and write cw. If I order in a restaurant, I say: Can u give me 2 of those ufb steaks, pls? Everybody understands that, why should I change the way I speak? Ok, I'm German, but I talk and write cw in English. I even dream in abbreviations, which is much more effective! OK, I did give up telling my yl that I didadidit dadadah didididah dit her...

As my YL is also a fellow ham, in the morning I ask her: dear YL, is there a lot of QRM and QRN on the QRG? Should we QSY to another QRG or change our QRA? All right, a bit QLF today so my QRP CW is not ufb. See, that comes quite easily, you should practice a bit....
:-P

Ken - NM9P

Q-Signals were created to be an international CW abbreviation for those who didn't speak the same language. They have morphed into voice modes over the decades, but they still serve the same function in international contacts where not everyone speaks the same language. or at least not with the same fluency.  Someone can say QRM, QRM and be understood when saying "There are a lot of people interfering with you" would not be understood.
   
But then, Anglo-centrism is a problem on the ham bands.  I have heard English speaking hams fire up right on top of stations of another nationality as though they didn't have a right to exist on "their" ham bands, and as though they wouldn't really be causing harmful interference to the other stations because they were speaking another language.
