This week I am testing a Flex-1500 SDR the smallest SDR from Flexradio My first experience with SDR. I am very impressed! This small modem type box is a complete transceiver It has superb receiving. PAN is an extra dimension to radio. It has incredible small filtering a square shaped 25Hz filter no ringing! POWER SDR gives super radio-front control offering possibilities not seen before I need some time to get used controlling everything by mouse. There are special control wheels too. On the other hand the conventional radio's like my K3 is also constant connected and controlled by a PC. Definite this is the future of radio. Then I saw the new power fets 144MHz 3w drive 1250W RF out! woow 50V 30amps A simple small PCB 7x14cm on a cooling block 50V Power thats it! That's the end of the PA tubes too... the MRFE6VP61K25H...
