SDR caught my interest in 2009 when I saw an SDR1000 on E-Bay, including the a destop PC. In a few days I was operating very well using the Windows XP software that came with the PC. No problems whatsoever but of course seeing the adds on the Flex Radio site, I became hungry for something newer than the SDR 1000. In 2010 they began advertising the Flex 5000A and immediately ordered one from Austin, Texas with the built-in tuner, and second receiver. Recently we had the VHF/UHF installed when shipping it back to Texas. I must admit, it has been the best ham radio rig I ever had and have went through my share of Kenwood, Icom etc. Since I first started using SDR radio, I have accumulated over 26,000 contacts in almost 3 years and have shoe boxes full of QSL cards. I only operate CW unless I talk to locals on 6 or 2 meter FM using the installed V/U unit. Have yet to apply for any DXCC or WAS since am too busy operating. So, go ahead and join in the fun by getting an SDR transceiver, either the 5000A or even the model 1500 which is a QRP transceiver.
Having my Flex 5000A is like having a laboratory instrument being able to communicate using precise frequency control. If you enjoy SSB, it is loaded with features such as a 10 band equalizer, terrific filters, ability to null out interference etc.etc. GOOD LUCK
