[Flexradio] SDR-1000 makes clicking sound when not powered on but DC available
This may be an easy one. My SDR-1000 clicks when not powered on but DC power is available to it. The click is not particularly loud but is enough to be annoying. Of course it stops when one power lead is lifted from the power cube but that's a little annoying to have to do. I have a switching DC PS (Samlex) that powers a "DC Power" power cube which then has Andersen Power Pole connectors feeding this SDR as well as a brand Y radio. Having the brand Y radio in or out of circuit makes no difference. BTW, I have TWO SDR-1000's and BOTH do this identical thing. Ideas?

[Flexradio] PSDR 2.0.22 s-m-o-o-t-h
Thanks to the crew at Flex-Radio for a smooth upgrade! I've installed PSDR 2.0.22 on both a Win7 box and an XP Pro box and have run a 1500 on each. On the XP Pro box the 1500 is joined with a 2M-10M transverter (on the XVTR common port) as well as an HF antenna on the main antenna port. Auto-switching of ports is working happily with band changes. Nice. Thanks for the fabulous upgrade. I'd previously run 3 of the RC's prior to 2.20 going golden. 73 de Lowell K9LDW ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
[Flexradio] XP to W7 questions
Hi Folks, May I suggest using separate hard drives in the same box? That way you can keep your installation "as-is" for XP. Add a new (or just 'another' if one on hand) hard drive to your existing system and select WHICH hard drive to boot from in your PC's BIOS. Usually that's a reboot, a Function key and a few selections then another reboot, after which you are booted in the just-selected O.S. On the 'new' drive you do a full, new Win 7 install and operate as if it's a new P.C. I do this on various boxes and it almost always plays well. It requires no special software (other than the second O.S.), repartitioning to accommodate sub-OS tools, etc... just a little patience to make the switch. I have *never* seen an XP to Win 7 migration go well and MUCH prefer a clean delineation between the two. That's my 2 bits. 73, Lowell K9LDW ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
[Flexradio] WTB: QRP SDR-1000 or 1500 for transverter use (2nd posting)
Hi Flexers, I am seeking a (2nd) SDR-1000 or a 1500 for QRP use to link up with transverters. Anyone wanting to change up? So far one non-QRP SDR with 2M transverter came forward... any others? 73, Lowell K9LDW ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
[Flexradio] WTB: QRP SDR-1000 or 1500
Hi All, I am seeking a used SDR-1000 QRP or maybe a 1500 if someone is upgrading to other models. This would be for secondary / transverter use, hence the QRP. Early versions or more recent... either OK. Please reply off-list with pricing, any particulars.

[Flexradio] Feds snub open source for 'smart' radios
Feds snub open source for 'smart' radios By Anne Broache, [EMAIL PROTECTED] CNET News.com Published on ZDNet News: (http://news.zdnet.com/2001-1_22.html) July 6, 2007, 4:00 AM PT Mobile-gadget makers are starting to take advantage of software-defined radio, a new technology allowing a single device to receive signals from multiple sources, including television stations and cell phone networks. But a new federal rule (http://dw.com.com/redir?destUrl=http%3A%2F%2Fa257.g.akamaitech.net%2F7%2F257%2F2422%2F01jan20071800%2Fedocket.access.gpo.gov%2F2007%2F07-2684.htm&siteId=22&oId=2100-3513-6195102&ontId=3513&lop=nl.ex) set to take effect Friday could mean that radios built on "open-source elements" may encounter a more sluggish path to market--or, in the worst case scenario, be shut out altogether. U.S. regulators, it seems, believe the inherently public nature of open-source code makes it more vulnerable to hackers, leaving "a high burden to demonstrate that it is sufficiently secure." If the decision stands, it may take longer for consumers to get their hands on these all-in-one devices. The nascent industry is reluctant to rush to market with products whose security hasn't been thoroughly vetted, and it fears the Federal Communications Commission's preference for keeping code secret could allow flaws to go unexposed, potentially killing confidence in their products. By effectively siding with what is known in cryptography circles as "security through obscurity," the controversial idea that keeping security methods secret makes them more impenetrable, the FCC has drawn an outcry from the software radio set and raised eyebrows among some security experts. "There is no reason why regulators should discourage open-source approaches that may in the end be more secure, cheaper, more interoperable, easier to standardize, and easier to certify," Bernard Eydt, chairman of the security committee for a global industry association called the SDR (software-defined radio) Forum, said in an e-mail interview this week. The Forum, which represents research institutions and companies such as Motorola, AT&T Labs, Northrup Grumman and Virginia Tech, urged the FCC to back away from that stance in a formal petition (PDF) (http://dw.com.com/redir?destUrl=http%3A%2F%2Fwww.sdrforum.org%2Fuploads%2Fpub_439156SDRF-07-A-0012-V0_0_0_Response_to_MOO.pdf&siteId=22&oId=2100-3513-6195102&ontId=3513&lop=nl.ex) this week. Those concerns were endorsed by the Software Freedom Law Center, which provides legal services to the free and open-source software community, staff attorney Matt Norwood said in an interview this week. Still, in a white paper released Friday (http://dw.com.com/redir?destUrl=http%3A%2F%2Fwww.softwarefreedom.org%2Fresources%2F2007%2Ffcc-sdr-whitepaper.html&siteId=22&oId=2100-3513-6195102&ontId=3513&lop=nl.ex), the group says there's also good news for its developers in the FCC's rule: because it focuses narrowly on security-related software, it appears that programmers would not be restricted from collaboration with hardware makers on the many other kinds of open-source wireless applications. (Many 802.11 wireless routers that are under the FCC's control already rely on open-source systems for network management.) Software-defined radios--also known as "smart" or cognitive radios--are viewed by some as the foundation for the next generation of mobile technology. Traditional radios use electronic hardware to process signals--for example, to transform a particular type of radio waves into a radio station's musical broadcast or to screen out interference. Expanding radio's scope But software-defined radios put the brains of the operation into software that manages the signals being sent or received by the radio hardware. With that approach, new software downloads, as opposed to more labor-intensive hardware changes, could let radios do more than ever before. Imagine, for instance, a single gadget that can deliver TV shows, terrestrial radio stations, cell phone calls and broadband, depending on how it's programmed; or a cell phone equipped with the intelligence to detect the strongest signals in a particular area and change the phone's settings to subscribe to them, regardless of whether they belong to a GSM, CDMA or some other type of network. Although the software-defined radio industry has generally found welcoming treatment on the FCC's part so far, some security experts said the agency's recent take on open-source software is unjustified. "Obscurity works best when the hackers can't test their attacks," said Peter Swire, an Ohio State University law professor who has written about the tensions between closed and open approaches to computer security. "For software like this, used in distributed devices, there should be no extra burden on open source." There's also no clear evidence (http://news.zdnet.com/2100-3513_22-1022469.html?tag=nl) that the number of vulnerabilities in open-source software differs dramati
