Tradeoffs between satellite systemsĪirtime vendors, check the prices at Iridium units and Inmarsat isatphone have different strengths and weaknesses. This entry was posted in Pactor modems and connecting to them and tagged pactor, scs, ssb on Februby Stan Honey. If your modem has indeed been upgraded to Pactor-III mode then Airmail will detect that, and use it. Leave the modem selection in AirMail set to your modem model number. If it is possible, the ESN retrofit and P3 license will cost around $350. contact Gary at Farallon Electronics to find out. no barcode sticker on the bottom), it may be possible to have the modem retrofit with a hardware ESN. If you have a PTC-II or early PTC-IIe that does not have an ESN (i.e. This license-codes are not transferable to a new owner and are no longer available. For earlier modems, all PTC-II’s and early production PTC-IIe units, without an ESN, the original policy was for SCS to issue a license code that was keyed to the user’s callsign. For later modems this Pactor-III license-code was keyed to the modem’s electronic serial# (ESN) and was transferable with the modem. Pactor-III mode was developed after the PTC-II and PTC-IIe were introduced, and was an “option”– part of the newer firmware-updates but had to be “unlocked” with a purchased license-code. But for those with greater communications needs, Pactor-4 offers a way to increase capacity. We expect that PTC-II-family modems (licensed to use Pactor-III) will continue to be used by most SailMail members because of the significantly lower cost. SailMail’s stations are all capable of all modes including Pactor-4. We strongly encourage all members to use at least Pactor-III. P4 is somewhat faster still, particularly with strong signals. Pactor-III transfers data 3-4x faster than Pactor-II with good signals, and is slightly faster than Pactor-II even with weak signals. Any previous PTC-II, IIe, IIex, IIpro, or IIusb modem can be licensed to use the Pactor-III protocol for a fee (paid to an SCS dealer or to SCS, not to SailMail) but can’t be used for P4. Current modems in production are the PTC-IIIusb and the P4dragon, and are recommended. SCS model numbers and pactor modes are confusing.

If you have an older Mac that uses a PowerPC chip (2006 or earlier), you can use VirtualPC. For details on how to run AirMail on a Mac using WINE/Crossover see: Thanks to Stas’ Lewak for this information. WINE (specifically Crossover) runs as a program on your Mac, and provides AirMail the environment that AirMail needs in order to run. Using this approach you don’t need to buy a copy of Windows. In both cases you need to buy a copy of Windows.Īnother approach to running AirMail on a Mac is to use the Mac version of WINE. See BootCamp also works fine for Mac’s with Intel chips but does require re-booting to change between operating systems. Parallels has the advantage that you don’t have to re-boot to switch operating systems. You then run AirMail in the Windows environment on your Mac. If you have a newer Mac that uses an Intel chip you can use Parallels or BootCamp to run Windows.
