Flex 3000 Update

Well I have had the Flex 3000 up and running for awhile now.

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.

VP8ORK Some Success

Well I only had a little luck with VP8ORK. I worked them on 30 meters and 160 meters. I’m real happy with the 160 QSO with my 29 foot vertical but I really wanted to work them on 80 meters. A couple of nights they were almost strong enough but not quite. 160 ended up being pretty easy however. I’ve still been working away at 80 meters. I did get WH0DX for a new one and I am hoping I made it into the log for HS0ZEE but he was weak and there was bad QSB so I am not sure. I am hoping I can pick up S9DX and T30OU or T30YA on 80 meters before they all move on. Hopefully I can pick up something new in the contest next weekend. I just realized I don’t have Argentina on 80 and that shouldn’t be too difficult.
