Raw Video ISS FM Repeater pass over Chattanooga

Here is a sample with what you can do with a Kenwood D-72 Portable in DUPLEX mode. Uplink Freq is 145.99 with a 67Hz PL. Downlink receive starts at 437.810 on approach then 5 Khz shifting down as it approaches. When it is at the highest I shifted to 437.80. You can do this on a portable and good antenna.

Hi Don, thanks for the demonstration! 73 from Germany

Do you need to have the CTCSS tone set on the downlink UHF frequency, or just the VHF uplink? I setup some additional channels with some offset to compensate for Doppler shift, but have not tried to listen in yet.

Nice! When did the repeater get turned on? Thank you for all your videos, Don. Your enthusiasm is contagious. :)

Why does the screen say Dup?

[@w6gps]

because it is in full duplex mode you can listen on the downlink while transmitting to the uplink
