HELP! I want to be able to interface 7 transverters to my Flex 5K.
I have the following transverters: 1. DEMI 222 MHz 28 MHz input (in shack) 2. DEMI 1296 MHz 28 MHz Input (in shack) 3. Old Microwave Modules 144 MHz 28 MHz input (in shack) 4 DEMI 902 MHz 144 MHz input (in shack) 5 DEMI 2304 MHz 144 MHz Input (on tower) 6 DEMI 3456 MHz 144 MHz input (on tower) 7 DEMI 10 GHz 144 MHz Input (to be on tower in the future) I have come up with a switching scheme which utilizes a 6 Position 3 Deck switch. Position 1 Deck 1 goes to the coil of a coax relay which connects the 5K 28 MHz transverter output to the 222 MHz transverter. Deck 2 is Open. Deck 3 connects the Yellow PTT line on the Flex 5K to the 222 MHz PTT input. The Red and White PTT lines are in use to key 6 and 2 meter amps.) Position 2 Deck 1 goes to a the coil of a coax relay which connects the 5K 28 MHz transverter output to the 1296 MHz transverter. Deck 2 is Open. Deck 3 connects the Yellow PTT line on the Flex 5K to the PTT input on the 1296 MHz transverter. Positions 3, 4, 5, and 6 of Deck 1 go to the coil of a coax relay which connects the 5K 28 MHz transverter output to the Microwave Modules 144 MHz transverter. Deck 2 goes to a coax relay which connects the output of the 144 Microwave Module transverter to the 902 MHz transverter. Deck 3 connects the Yellow PTT line on the Flex 5K to the PTT input on the Microwave Modules 144 MHz MHz transverter. Position 4 (Deck 1 See Above) Deck 2 goes to a coax relay which connects the output of the 144 Microwave Module transverter to the 2304 MHz transverter. Deck 3 connects the Yellow PTT line on the Flex 5K to the PTT input on the Microwave Modules 144 MHz MHz transverter. Position 5 (Deck 1 See Above) Deck 2 goes to a coax relay which connects the output of the 144 Microwave Module transverter to the 3456 MHz transverter. Deck 3 connects the Yellow PTT line on the Flex 5K to the PTT input on the Microwave Modules 144 MHz MHz transverter. Position 6 (Deck 1 See Above) Deck 2 goes to a coax relay which connects the output of the 144 Microwave Module transverter to the 10 GHz transverter. Deck 3 connects the Yellow PTT line on the Flex 5K to the PTT input on the Microwave Modules 144 MHz MHz transverter. Note: The 902, 2304 and 3456 MHz transverters are RF switched. Haven't thought about the 10 GHz unit yet. Unless I have forgotten something, the above should work. It will require moving the switch every time I want to change bands. The switch can, of course be mounted at the operating position. All of the transverters will be in another room. But, it would be nice if I could delete the switch and wonder if there is some signal I can get out of the Flex 5K that I could use to automatically do the job of switching the various relay coils. I had hoped that the Flexwire connector would be of some help, it does not appear to be. Am I missing something? Any help and/or suggestions would be most welcome. 73, Bill Tynan, W3XO _______________________________________________ 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.flexradio.com/ Homepage: http://www.flexradio.com/
