Hi Tim,
I'm curious about what "symptoms" you're experiencing with your Aspire One, which I'm also using. ? In my case, during the short time I had available?to use SatPC32 with mine netbook just before leaving the country, I found that the Doppler corrections from the program were slow in keeping up with what the satellites were actually doing.
That is, once I had a station tuned in on the 70cm freq, the?corrections would kick in at the right intervals as I'd set them, but the corrected?downlink freq would soon be off a bit following the next correction. (The downlink freq displayed on SatPC32 matched what the rig's display showed, so the rig and program are talking fine.)
With each correction applied, the disparity between the new downlink freq and what I?was actually hearing would quickly widen. Soon, I would have to manually re-tune the station again to clarify the signal; the uplink?seemed to follow my hands on?changes though, so that seemed to be a functional "band aid".
There's one issue on my end that may figure in. My FT-817ND is at Yaesu for a warranty repair, so I'm currently limited to half duplex only with my FT-897D. With that single-rig config, I can't use a rapid correction interval because the rig switches VFOs at the specified intervals (currently set at 50 cycles), and I lose my RX capability for a noticable amount of time, say about a half second each time. The VFO switches become more frequent as the bird passes overhead of course, so it's a trade off.
I've been stuck in Bahrain for the better part of a week while waiting for the military hop that goes to Diego Garcia where my ship is located. My rig is on the ship waiting for me, so it'll be a few days?before I can try anything new.
With luck, my 817 will be shipped to me while I'm at VQ9 and I'll be able to go full duplex with a much faster Doppler interval setting.
73 for now,
Jim, ND9M / VQ9JC Manama, Bahrain

Simon, ? I will be thrilled if you are able to get the Doppler-tuning function to work with stability on a netbook with an Intel Atom processor driving an 8.9-inch screen (the one built in to my Acer Aspire One). :) ? Tim - N3TL

Well,
When I get to this stage I will offer to help anyone using teamview - I did this yesterday with a beta-tester in Holland and in just a few minutes found a serious resource leak. The main problem with netbooks is the graphics chip isn't too fast, but I do have some poor code in the satellite tracking anyway :)
My general aim is to be able to run HRD 5.0 on a netbook driving a 24" display.

That's excellent news, most encouraging.? Wish I was able to do more to assist.

\Jim,
I know I responded to you off the BB, but it occurs to me that I should post a response to the reflector.
I'm not having any symptoms at all when using SatPC 32 with the Acer. The combination works very well to provide Doppler tuning for my two radios.
I have never tried using computer Doppler control on only one radio. I haven't worked AO-7, FO-29 or VO-52 in half duplex
I notice another poster responded with information about getting SatPC 32 to talk to his Icom rig. Since I've been using Yaesu radios here, I can'tcomment on that at all. I have no experience with interfacing any non-Yaesu radio with any of the available satellite programs.
Simon has done a marvelous job with his HRD suite of software, and I enjoy using it very much. I would like to have fully separate access to Satellite Tracker because I suspect that could cure the processor overload I experience with the Acer. I may be wrong, but I'd sure like to test the theory.
73 to all,
Tim - N3TL Athens, Ga. - EM84ha
