SDR Game Changer?

I think the Baofeng SDRs have been a game changer, but let's see what FlexRadio Systems rolls out at Dayton on the higher end of the scale.

470 Amateur Radio Net - FlexRadio and Echolink

Paul, W4PGM, gave an overview of the FlexRadio, Software Defined Radio. He runs the FLEX-3000 and really likes it. He compared it favorably to many other HF rigs he has run. Since it is software based, he says it is easy to apply the updates that come out every 6 months or so. The updates may change the tuner from a 5-to-1 to a 7-to-1 or improve the noise blanker. Even without the customary buttons or dials on the radio, it is very configurable - you just use the PowerSDR software from your PC. It sounded like any fairly recent computer would be sufficient as long as you have or can add a Firewire port. Paul really liked its abilities in digital modes. On the band scope, you can pick a peak, representing a signal, and click it to tune to that frequency.

He mentioned a couple of issues with the CW and notch filtering, but says the company is working to resolve those issues. He also said that contesters may not like the software, because it doesn't integrate into the popular logging programs - you have to manually change the focus of the windows to switch between apps.

Also, Rick Sr., N4JTQ, explained the problems they were having getting the Echolink working on the KJ4HPM/443.225 repeater. I was glad to find out it wasn't just me.

From the 470 ARG Newsletter:

"Hopefully we will have our ECHOLINK up and running by this WEDS going through our club repeater of 443.225, thats one reason the news letter is a little early.. the link will be KJ4HPM-R on the search bar at ECHOLINK."

As I mentioned earlier, I think that EchoLink is a good way to get into the hobby without a lot of expense. We are just waiting for TNJeff to get his ticket, so he can sign-up. The air waves will never be the same. I believe both my IC-7000 and the KG-UVD1P will work on 70 cm.

Also, Paul (W4PGM) will be talking about the Flex Radio on Thursday night. And, they are thinking about doing an Extra class. I'd really like to do that, but I'm not sure I have the time.

I like computers. I work with computers. I don't know that I would want a radio that is dependent on a computer like the FLEX-5000A.

From Brick O'Lore

I find it interesting that it requires FireWire. If I were to go this route, I would want a dedicated machine. Or it would be nice if you could virtualize it. My father-in-law seems impressed with the specs and the QST review was mostly positive. (I think some of the problems the reviewer had were PC/Vista related, but that is a legitimate complaint for a Software Defined Radio.) One of the guys that is often on the 940 repeater really likes his FlexRadio and may upgrade to the 5000A.
