One wonders if Dayton's lack of security will ever be an issue? The Hara posting no Weapons allowed, even for those with permits, was not very reassuring. Dayton is rough and having a large amount of cash transactions purposely left unprotected is an issue. Guess the few police and rental-security will keep us safe. Given the age and ambulatory state of many Hamvention attendees the broken pavement, deep pot holes, uneven flooring and other "hit by" & "trip fall" hazards are an issue. In many other states and cities the Hara as it is is unlikely to have gotten public event permits. While attending tradeshows and hobby events in many other venues, including overseas, I've not seen anyplace as sorry at the Hara. Every year I wonder why we put up with the place. Thinking of checking out Hamcon or Hamcation for 2014 myself. 73 Steve K9ZW BLOG (Including my Dayton 2013 Recap): http://k9zw.wordpress.com/

Now that the 5000A is discontinued, it might be a good time for Flex to update their web site. It still has pictures of the 5000A front and rear panels with the caption Front-panel view of the new FLEX-5000A full duplex 160M through 6M 100W all mode transceiver. I think that "new" is no longer applicable here!  They do have a nice announcement explaining the end of production of the Flex-5000A 73 Steve K9ZW BLOG: http://k9zw.wordpress.com/

eHam Forums / Software Defined Radio / RE: Thick-Pipe vs Thin-Pipe SDR Configurations
|
on: May 22, 2013, 08:34:15 AM

IMO, the thin-pipe approach is where Flex should have started, not the thick-pipe used in the current models. Using an operating system not designed for real-time processing to process time sensitive data is just a bad idea. It's what lead to the lag issues with CW and the stuttering issues some people have seen with the Flex-5000.
The other big issue is that Flex has no control over the hardware used on the PC end. There are all sorts of bizarre combinations of hardware/software out there that are not conducive to smooth operation of what essentially is a real-time system, plus you have people who don't know what they're doing playing around with configuration parameters and driver settings with no idea of what they're trying to accomplish, or why.
Keeping as much of the core signal processing in the box and off the PC is a good thing.
Decoupling my criticism of how Flex handles product announcements from the product itself, I think the Flex-6x00 is actually a very interesting design with lots of potential. They just need to moderate their promises and deliver on the ones they do make.
Back in 2005 to 2007 when the PowerSDR Thick-Pipe approach was developed the processing power of PC was needed to make the technology accessable to amateur radio enthusiasts. Much of the processing power needed for a Thin-Pipe approach was then either unavailable, wasn't capable enough or was too expensive for ham radio. "Uncle" may have been willing to pay $50,000 for a radio, but very few hams were likely to do so. The drop in costs has made the new products affordable. When compared to $10,000 plus transceivers from a number of manufacturers the new Thin-Pipe products are a good value. You're right that the external PC has been troublesome in the Thick-Pipe model. This should be fairly close to a non-event in the Thin-Pipe model. 73 Steve K9ZW BLOG: http://k9zw.wordpress.com/

eHam Forums / Software Defined Radio / Thick-Pipe vs Thin-Pipe SDR Configurations
|

Very interesting aspect of the presentation at the FlexRadio Systems 2013 Dayton Banquet was the distinction between the Thick-Pipe PowerSDR older configuration using the distributed processing of the SDR Device and PC in an intertwined fashion, and Thin-Pipe SmartSDR where all needed processing is undertaken in the SDR Radio Server and the PC is just an interface to the user. Would seem that Thick-Pipe will remain a favorite of the deeply involved experimenter and hobbyist, while Thin-Pipe generally will appeal more to those seeking raw performance gains. Lots of discussion going on about these two concepts with their pros and cons. 73 Steve K9ZW BLOG: http://k9zw.wordpress.com/

The Windows Focus Management issue is not unique to SDRs. You can experience the same issues using CAT programs with loggers. There are TweakUI and Registry adjustments that can help, though it is almost always possible to miss-focus when running several active programs. Other techniques include Focus Management programs, use of Touch Screens, running VMs with various programs "sandboxed" (which in many ways is using the VM software to do Focus Management) and use of special outboard hardware. Case in point, the Windows Focus Management issue has nothing to do with the Flex-5000 being retired. 73 Steve K9ZW Blog: http://k9zw.wordpress.com

Very interesting Dayton 2013 FlexRadio Systems Dinner Presentation. Not unexpected news, but unexpected timing, that the Flex-5000A is out of the product line (and no mine is not for sale). Lots of neat things - FlexRadio Systems sending a tablet running a weeks old remote control application around the 180+ person crowd so everyone could have a try, great presentations, and a chance to play with the demonstration units. I've written more from the first hand "I was there" and "I tried the demo software" POV. 73 Steve K9ZW Blog: http://k9zw.wordpress.com/

Gents, eHam's moderators asked me to very sharply limit posting links. I do try to capture some of those links in my own writings. Sorry for the two-step. Am I pumped to get a new radio? Absolutely! I rather enjoy the fun of that aspect of this hobby. Did you read about The Mojo FPGA board I've started with? One ham radio experiment leads to another .... there is so much to learn! Sorry if I disappoint some of us by not doing the "Eeyore" pesimistic doom and gloom slow walk though this hobby. Just don't see it that way. I sure understand those who do - some enjoy "leading edge," even at the risk of "bleeding edge." Others enjoy their stalworth S-Line station from 1962. Then some of us enjoy them both! Oh, and enjoy the PowerSDR based Flex-5000 too. A few very clever sort design and build these leading edge things. Their lives must really have an impassionment for the hobby! All best and join me in enjoying the various bits of news as it rolls out, it is interesting and if you have your name in the order queu it is rather exciting too! Let's have some Amateur Radio fun! 73 Steve K9ZW Blog: http://k9zw.wordpress.com/

I am sure its going to be quite the SDR, I have little doubt about that.
Of course, SDR is all about Software. .....
All that said though, when done it should be a very nice transciever if the software is stable.
It will interesting to see how the SmartSDR (which is sort of like a "thin client" of SDR software) performs compared to PowerSDR (which is more the traditional distributed SDR software format). Remember the process has to be there up and running to even do these demos. The disconnected hooks are the HMI/GUI portion. We'll also see over time if the strategy of having the "meat & potatoes" of the SDR all in the radio box (6x00 series) is more long term stable than the "half & half" SDR critical processes split between the radio and computer (5000/3000/1500 series)? Fun stuff! 73 Steve K9ZW

There are reports that the Alpha/beta 6500/6700 testers have now been released from their NDAs. Their first production radio end user reports heading for their blogs very soon. 73 Steve K9ZW Blog: http://k9zw.wordpress.com/Steve, read the same thing on the Flex Yahoo Group. Also, noted that it is part of an "extended" beta group. Don't know if that is the extent of the shipping or not. If not, then there will be a lot of early buy in's that will be disappointed. I have read a couple of posts from people that bought in at Dayton last year and have not received any notification of shipment or final payment request from Flex. Some have already paid out and are only awaiting notice of shipment. Lots of folks on edge about this one. I do hope that Flex starts shipping to more than just a select few "beta testers". Otherwise, they will take a pounding on all the forums and user groups. (even more than they already get) One thing I noticed from the previous newsletter that was posted to the public on the Yahoo Group, is the radio's slice sizes have been upped dramatically!! From a max of 384Khz each to several Mhz in a single slice! That seems to have been lost in all the other talk. How useful that might be is open to debate. Without a very broad banded antenna, it might not be that useful. But, an interesting development all the same. Having played around with the 6700 at Belton, just made me want one more! But, it's not going to happen for me anytime soon. (work in the oilfield in my area has fell WAY off!) But, maybe by the time things pick up, I'll be able to afford one! james WD5GWY The slow roll out is FlexRadio's call - I can see some sense in what they are doing, and holding a very early position if the order number observations hold true I am as eager as anyone to get my hands on the new radio. That said I am <<VERY>> content to be patient if the radio isn't ready. The slice size increase is really awesome - and the ability to make very decent use from non-optimal receive antennas has caught my attention. I had worried that I needed naturally resonant antennas on all bands (my current set up is 1:1.2 or better from 1.3 gHz to 20m, and on 40m, but requires significant tuning for 75/80 and 160m due to shortened antennas. It also needs help to tune 60M and 30m, and requires antenna switching at the 40-20m and 6-2m jumps) though the videos and reports suggest I may have other alternatives. Rather I'm pondering how to get a second antenna cluster configured to make use of diversity reception. Will be an interesting learning curve on my part when my order does arrive! 73 Steve K9ZW Blog: http://k9zw.wordpress.com/

eHam Forums / Software Defined Radio / RE: PowerSDR 2.6.4 - Huge Disappointment
|
on: May 05, 2013, 03:08:12 PM

Wanted another day of QSOs with the new 2.6.4 version. Install was slick and quick. This release did update the drivers and the firmware. Latency improvements noted (running the provided utility) and was able to adjust to meet the improvements. No sign of a several small glitches in my system - not crediting version 2.6.4 as much as the overall reinstallation process for cleaning up some loose ends with the 2.5 version. Of course none of the regionalization updates matters for my operations. Those updates are important for the overall FlexRadio community and bundling them with the general updates & tweaks is a good idea. Noticed more even drive when band-hopping. I hadn't been 100% confident of the resulting levels with the prior release which had lead to my reducing power to avoid amp overdrive. Oh and for the down on SDR/Flex anywhere in life folk, very please to note the installation of PowerSDR 2.6.4 had zero adverse affects on my S-Line station..... In summary, a nice and easy upgrade that a few days of use suggest was worth it for drivers/firmware/tweaks alone. 73 Steve K9ZW Blog: http://k9zw.wordpress.com/

Seems like the only one shouting or belittling here is you. I posted my experiences with my Flex 5000 and you jumped right in here accusing me of a lot of things. This is not Amateur Radio like gentlemanly conduct on your part.
-robert
Posting how your first hand personal experiences with upgrading to PowerSDR 2.6.4 would make you a contributor to a thread discussing the software upgrade. The rest of what you post doesn't begin to meet the standards you suddenly seem to have become aware of. Again how did your upgrade to 2.6.4 go? 73 Steve K9ZW You know, no wonder the anti-Flex crowd dislike you guys so much. You are JUST AS GUILTY of jumping on anyone who says something negative about their experience with Flex Radios. Unless it is a glowing, over the top review of Flex's stuff, you guys all come out of the woodwork on attack. I don't know which side is worse, but right now I am leaning towards the pro-Flex group as being the worse here. -robert What - you've never installed/used 2.6.4? Guess you have some homework for the afternoon.... 73 Steve K9ZW
