Matthew,
OK, thanks for the info.
I'll set my Memories for 435.160 up and 145.980 down. They aretunable on my IC-820, so I can adjust each on the fly to accountfor Doppler.

At TCA up is 435.170, down 145.980.

So accounting for doppler with 5khz steps, 435.160 at AOS, 435.165 halfway to TCA, 435.170 at TCA, 435.175 halfway to LOS, and 435.180 approaching LOS.

I also find it necessary at times to tune the downlink to 145.975 after TCA, although not always. Just depends on the pass.

73,
