I like FLEX - no I love FLEX, so that is why I am putting so much effort into questioning the "60 Watt Factory Installed" as the standard VHF-UHF upgrade offering. I could be wrong!!!
I've had an order in for a very long for the VHF-UHF upgrade, I assumed that 30 watts would be the standard. When I received the actual invoice from Julie - it showed 60 watt was on order. That was not correct - I wonder how many other advance orders were incorrectly assumed to be for the 60 watt version??? Am I the only one? Please let FLEX know what version of the VHF-UHF you actually want to buy. It may be a simple accounting glitch. I did a quick survey of VHF and UHF amplifier drive requirements; here is what I found... Henry 2000 series 25-35 watts input for 800-1000w out CommanderII ( Palstar ) 10-15 watts nominal, 30 watts max for full output. Tokyo High Power HL350Vdx 10w / 25w / 50w Manual select - note you must install a bank of attenuator resistors for 25 watt input and two banks of attenuator resistors for 50 w input. Tokyo High Power HL500V 20W / 50W , Manual Select - note you must install a bank of attenuator resistors for 50 watt input Tokyo High Power HL250UFX 10W / 20W / 50W Manual select - note you must install a bank of attenuator resistors for 20 watt input and two banks of attenuator resistors for 50 w input. ITB - I0JXX 350MOD144 5 watts in for 350 watts out 500MOD144 3 watts in for 500 watts out 1000MOD144 10 watts in for 1000 watts out 300MOD432 5 watts in for 300 watts out VK4DD BLF248-MARK-II: 30 watts in for 600-700w out VK4DD BLF248-PA: 15 Watts in for 300-350w out Communication Concepts CCI/Motorola/Helge Granberg Amplifiers for 144 MHz: AR305 15w input for 300w out AR313 15w input for 300w out As VE3KH correctly points out, Yes the Henry 3000 series VHF / UHF amplifier, and similar home brew amps do need considerably more drive. Thanks, Kevin, and nice to meet you - hope to work you on the air soon. _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/ Message delivered to arch...@mail-archive.com
