Thanks, Chris. Yes, Al did a very good job with his tutorial.
SDRBridge 1.5 is so much better than the old version.

Thanks Chris and Alex,
Ed's SDR-Bridge makes using CW Skimmer with the Flex radios a pleasure.   And he keeps improving it, like the recent addition to support multiple FlexControl knobs.  

I'm glad to hear the quickstart guide is helpful.   As we see changes to CW Skimmer, SDR-Bridge and SSDR I'll continue to teak it as needed.  

Regards, Al / NN4ZZ

Al, CW Skimmer and SDR Bridge are great programs, as they allow
me to decode CW that is faster than my abilities. I'm good to up to
25 WpM, but after that... I'm just now decoding at 39 WpM on 7,027...

If I have CW Skimmer do I really need SDR Bridge in order to make it work on my FlexRadio 6500?

I was playing with it yesterday and it seemed to be working OK so I'm a little uncertain as to what SDR Bridge brings to the set-up. I had set it up using Al NN4ZZ's document as a guideline but without SDR Bridge.

I'd be very grateful for some advice on this.

Hi David,
The SDR-Bridge provides a very reliable connection between the radio and CW Skimmer.  It doesn't require a CAT com port and the omnirig program.  It also has a number of additional features  (up to 4 skimmers, splits, FlexControl support, etc).  

FRS recommends it as the way to go.  Here is a snapshot from about 8 months.  The post was from someone having connection/setup issues.

Thanks Al.

Setting-up SDR Bridge will now be my next job for the coming week!

Thank you for your first-rate document as well!

Incidentally, I'm doing all this from scratch on a new Surface Pro 4 Tablet purchased just for the purpose of running my FlexRadio 6500.

Hi Andrew,
As you noted, there are some issues but overall CWS works well when using SDR-Bridge to link to SSDR.  Here is an update from another forum about what we can expect to see regarding CWS over the next year or so.  The update is based on an email from Alex. 

***********************************  Update from Jan 2017 ****************************

The current version of CW Skimmer is V1.9 and there have been some questions about whether there will be any more updates.  While no more updates are planned for the current program, Alex / VE3NEA is currently working on a new and improved skimmer program.  It will be a multi-mode Skimmer with support for many SDR radios.  

No more details are available and it will likely be late in 2017 or 2018 before it is released.  This is a complete re-write.  Keep in mind that the original CW Skimmer took him about 8 years to develop.  He plans to add some of the various enhancements that have been requested over the last few years so this is exciting news. 

Details will be announced on the DX Atlas Yahoo forum when it is ready.

the new re-written CWS will indeed be something to look forward to. I'm not in full agreement that the bridge "works well" with SSDR.  It works... but "well" is a very subjective term.

Without SDR-Bridge, there is no way to sync the two degrees of tuning freedom (panadapters can tune and the slice can tune) that is inherent in the FLEX-6000 because CWS was not designed to handle it.  Other than the occasional loss of sync that is easily recovered by manually tuning the panadapter, I have no issues at all with SDR-Bridge.  However, if you are running the CWS waterfall with SmartSDR on the same PC, you need to make sure you have sufficient CPU to handle it because CWS dows not use any type of graphics hardware acceleration for rendering its waterfall.

Hi Andy,
Agree the new CWS is something I'm also really looking forward to.  I use CWS and SDR-Bridge almost daily since I'm CW only and aside from a few minor glitches it works very well for me. 

It would be really great if Alex and FRS would collaborate and implement the idea below to add the spots directly to the SSDR display.   

https://community.flexradio.com/flexradio/topics/pfskimer_what_is_the_possibility_for_a_smartsdr_dis...  

This would be a great option to eliminate the redundant CWS spots screen and  provide an integrated experience as well as show more spots than currently available.

Al, thanks for the great news about the new skimmer program, although I must
say that I have no problems with CW Skimmer and SDRBridge. I can even run
these programs on an old pentium machine as long as I use not more than 30
detectors.
