[QUOTE="Terryl, post: 1044408, member: 369937"] OK kids I think I found out what is going on with the RX side of this setup, my FT-847 does not have the wide bandwidth needed for proper RX and signal decode on these satellites, it looks like they need a receiver that can handle at least a 35 KHz IF band width, my FT-847 can only do 25 KHz, so I was a bit short. (BTW new antenna is still awaiting the finding of the SO-239 connector) So to fix the IF bandwidth problem I used mt VX-5R handy talky, it has a select-able IF bandwidth and can also be set to priority scan channels, I set it up for all the NOAA satellites that are still broadcasting and set those channels for priority scan and hold till carrier is lost. Now just going to have to wait till a bird comes by to test. [/QUOTE]
