Hi, RS; welcome to SI!

My comment to Maurice wasn't intended to address any propagation delay question. It was to chide him a bit about his stating that G* "wasn't twice as high", when it was in fact 1.8 times as high as Iridium. In talking about ROM (rough order of magnitude) numbers, I wouldn't pick on someone for calling a factor of 1.8 an approximate doubling.

The 5 millisec difference you mention certainly isn't going to be a very significant difference between the total latency of G* and I*. There are other delays which could be more significant.

I doubt that G* will use GEO relay transmissions for voice data, and certainly not for their premium voice service. Might do so for data, paging, control signals, etc.

Iridium delays from the RF link between their birds will also probably not be very significant. However, if data is transmitted in packets and buffered at each transciever, there could be significant delays between receipt and re-transmission. Multiply that by possibly several birds in the link between caller and destination, and you could have a perceptible delay. Might depend on traffic loading as well (longer digital queue -> longer delay).

G* call routing through terrestial links is also not free of such delays. It would be interesting to know how the guaranteed maximum delay of G* compares with I*. Does anyone on the channel know?

And a warm welcome to SI from me as well.

I find SI to be far and away the best investing discussion forum on the Web. Of course some threads are much better than others. This is I think a good one. Obviously you agree.

In addition to the really important thing, the much higher average level of discussion, SI also has much better discussion technology than either Yahoo, AOL, or the Motley Fool's web site, IMO. The ability to read other posts by an author is invaluable, as is the search engine, in my view. Even the ability to reference the post being responded to is much handier here.

But maybe you know all this. I'm unclear as to whether all this, other than actual posting, is available before ponying up.

<<and posting Readware's comments (I've missed seeing them lately BTW: has he stopped posting?)>>

There was some panic over on AOL that Readware had departed permanently as a result of a number of insulting remarks made to him in the heat of the political wars. They flaired over there much worse than here. He has however made one or two reappearances since his somewhat cryptic "I'm out of here" sign off a few days ago, so calm has more or less returned. <gg> Not to say I'm not relieved as well. <g>
