Steve gave an excellent presentation on the architecture of the 6000 series which includes some very good information as part of one of the Forum sessions at the Dayton Hamvention. The direct RF sampling approach coupled with the radio’s dynamic range of 140 dB creates a radio that has much lower distortion products and better selectivity that anything else which is currently available. It should also make a great contest radio as its capable of up to SO8V operation. The Flex-6700 can implement up to 8 separate receivers simultaneously allowing multiple bands to be monitored. This eliminates the need for roofing and other RF band filtering and allows the radio to operate on multiple frequencies/bands at the same time. I expect that this will be one very impressive radio! Unlike previous designs, the 6000 series radios directly sample signals in the RF domain and do all processing and detection of signals digitally. Fortunately, we had a chance to talk with Steve Hicks, VP of Engineering at FlexRadio to gain a much better understanding of the design, architecture and evolution plans for the Flex 6000 series.
Anita and I have a new Flex-6700 Software Defined Radio on order and we wanted to learn as much about the Flex-6700 as we could. We also spent quite a bit of time at the FlexRadio Systems booth. Tagged Contesting, CW, QSOs and QSL'ing, Software, Station Performance 2013 Dayton Hamvention
Posted in Contesting, CW, Software, Station Performance, QSOs and QSL'ing. It is challenging to learn CW but there is a great deal of DX available via this mode and I believe that some of the finest operators in the world use CW as their preferred mode. I would encourage our readers to try CW if you do not currently use this mode. The 2013 CQ WPX CW Contest was a lot of fun and it helped me to improve and build confidence in my CW skills. While all of these prefixes will probably not be confirmed, I am now within striking distance of completing this aspect of the award and I should be able to snag the final number of prefixes required to reach 600 confirmed via non-contest operating. This brought my total prefixes worked towards the CQ WPX Award of Excellence in CW mode to 550 of the 600 required. I was also able to make a little over 500 QSOs and worked 344 prefixes during the contest.
