Flex-Radio 3000 – Now 5000

When you get a new radio there are always some accessories or add ons you need to really get everything working. With a Software Defined Radio (SDR) like the Flex 3000 or Flex 5000 it is the same only some of those add ons are software instead of hardware.

Back to the Radio

I have been traveling and busy with other stuff for awhile here. I went to Nepal for almost three weeks, unfortunately not able to take a radio with me. We did have a lot of fun trekking all over and experiencing their culture.

Quiet Summer

There certainly hasn’t been much happening for me DX wise.

My Flex SDR Experiences

As noted in my previous post I had purchased a Flex 1500 SDR at the DX Convention in Visalia. It’s a QRP rig but I bought it as an inexpensive way to see if I wanted to go further with SDR. Primarily I wanted to see how the reception and filtering would compare with my FT-2000. I also wanted to see how operating a rig only with the computer would work out. I got it all hooked up and the software installed. The Flex 1500 uses a USB connection instead of Firewire so I didn’t have to get anything special for my existing PC. My PC is a Dell Dimension 9200 running Windows 7. Not state of the art but certainly should be fast enough. That was part of the test, too. Anyway, I started playing with it and there was a nice CW pileup going on up from a dx station. The filters are just incredible, I could wade into the deepest part of the pileup and usually just pick out a single signal. With my FT-2000 if you get the filter tighter than 400 Hz you start getting some ringing along with artifacts from the other nearby stations. With the Flex I had the filter less than 25 Hz and I could easily copy the station. This will be great for getting rid of the guys on top of the dx or picking out just the dx station when he is simplex.
