Sailmail goes up to $250 per yr on Jan 15/04 - any reasons given by them?
As I mentioned before, the Winlink team has been making
some changes to releive the conjestion. For example, connects used to be made in P1 mode, then switched up to P2 or P3 depending upon what was available. Now connections are made at P2 so negitiating the connection is faster. A number of other of changes were made as well. I haven't used it since last summer since we are out of the water for repairs until next summer sometime (hopefully). Sailmail has alot fewer users so it is definitely superior in that regard. I wish they would implement the catalog feature like Winlink though. Glad I wasn't imagining the problem with GRIB files. Doug, k3qt s/v Callista "Paul" wrote in message ... Comparing the GRIB to the actual weather, I really couldn't tell you if it was much better than random extrapolation from current conditions. It did seem to predict general pressure movements, and on the way back to San Francisco it did show the Pacific High being shoved south (allowing us to turn east at Lat 40, rather than Lat 45 or 50 that we were afraid we would have to do when we left Kauaii). We were cross-checking with the other WFAX products, but didn't do a careful post-mortem comparison. Anyway, we had enough fuel to motor across if we needed to (didn't need to). We only took the GRIB predictions for 1-3 days out. The wind direction and speed predictions in between the high and low systems weren't all that accurate, but once we got out of the transition regions it wasn't too bad. And, as they point out, GRIB won't show tropical storm activity very well. We were watching the storms come out of Baja during August and Sept -- the WFAX photos and charts were very useful, but the GRIB only showed a tiny ripple in the isobars. GRIB by itself doesn't cut it for sure. I really like the looks of the Winlink weather info catalog, and many of the Winlink system features, but I just couldn't reliably (read "easily") connect. SailMail was a solid performer for me, and I didn't have any problems with connect time. Of course, I was using Pactor III and just sending/receiving a few KBytes of email a day and receiving my daily 10KByte GRIB file. I will keep trying Winlink, 'cause I would really like to be able to use it. No doubt I can improve my results with better operating procedure. Best, Paul - wb6cxc - s/v VALIS "Doug Dotson" wrote in message ... While awaiting to cross over to the Bahamas last winter I spend quite alot of time looking at WX data. I was pretty disappointed with the GRIB data I was getting. It rarely matched the other prediction products from NOAA and when doing a post-mordem it rarely matched what actually happened. I quit using them. Perhaps in the Pacific they are more accurate but I was dissapointed with them in the FL/Bahamas area. Another nice thing about Winlink is that the total connect time per day is higher. I was able to download WX products several times per day. Also, I was using a base station in Gaithersburg, MD much of the time and it was almost always available and rock solid signal. Unfortunally the OP lost his job and had to shut down. He, and several other OPs increased my connect time quota since the WX systems were so active and fast changing during early Jan. Never tried the email FTP service. I did use the one Sailmail advocates though (Sailinfo was it called?). The catalog in Winlink was better and seemed to offer more products. Doug, k3qt s/v Callista |
