It's,satellite ready. Essentially in sat mode, adjustments to the down link are match to the uplink. So if you want to operate 5kz below the center of the passband. You adjust the uplink and the downlink will track up 5kz. Once you're their you unlink them and correct gor the doppler. At least that's how it's supposed to work.... The USB to serial cable I ordered is delayed, so at least another week before I can get the laptop to talk to the radio.

I thought the TS-2000 had all the doppler correction built in. Why aren't you using that since your laptop isn't attached to the radio????

All,
While planning upgrades to the shack, I've decided to try my hand at the linear birds again, taking myb TS-2000 outside and operating Semi portable. So far it has been a lesson in frustration. I've yet to find my downlink. Tonight I tried to get on XW-2C on the 0100UT pass which was 70 degrees from DM33.
First let me describe how I set up. (I finally solved the memory storage issue I wrote about a few weeks ago). basically it's just the radio into an ELK on my equatorial tripod mount and the laptop (Still waiting for the USB-->Serial converter to get SATPC 32 talking to the radio).
So I started at the center of the passband and using the doppler corrections in SAtPC, tuned the UHF uplink down to where Sat POC said it would hear at the sat and moved around bit trying to hear myself. Kept adjusting the uplink and also played with the other way Calling CQ on the uplink and moving the downlink trying to find myself.self Didn't hear jack the whole pass.
I did record the pass and thought I might have heard myself, but it was toow eak to discern my call or grid, (though it did kinda sound like me).
So, I guess I have two questions:
Is my methodology correct? if not what am I doing wrong?
Did anyone hear me?
I'm hoping once I get the Cable and SATPC talking to the radio, it might make it easier, but I think knowing how to do this manually should be skillset i should have.
Thanks in advance.

Rick,
You may want to try FO-29 in Mode V/U as it is higher and doppler moves more slowly. On 29 I would pick an uplink of 145.930 and listen and tune for your return from 435.877 at the beginning of a pass, to .863 by the end. There is a lot more activity and you are more likely to hear a return to your calls as well.
