The SCS SCS Pactor Radio Modem is truly the best radio modem money can buy. We have sold other modems, but the performance is so inferior that our customers were very dissatisfied with their systems, and they were harder to work and less reliable - not a good combination.
Since the SailMail and all the WinLink2000 stations now use PactorIII (they are still compatible with PactorII), you get the same effective increase on your signal. Signals that cannot be heard by the ear get through. It is the most amazing thing we have seen in over 35 years of transmitting data over radio.
NOTE: The SCS PTCII-usb modem is NOT COMPATIBLE with Windows Vista 64-bit operating system. There are NO DRIVERS available and likely never will be. The operating system of your computer can be found in the system properties under control panel.
Please contact us for alternate solutions if you have Vista 64-bit. This ONLY applies to Vista 64-bit. The PTCII-usb modem is compatible with all other Windows operating systems from Windows 2000 and up. It is YOUR responsibility to determine if you have Vista 64-bit. NO MODEMS WILL BE ACCEPTED FOR RETURN because of incompatibility with Vista 64-bit. You have been warned.

If you check the installation recommendations on the SailMail website, you will see that they recommend installing a device called a Line Isolator on the coax cable and two ferrite beads on the control cable. This is already on your radio if it was purchased from us. If it wasn't purchased from us, it is a 99.99999% chance that they are not installed. You need these to make your system work properly. They greatly reduce the amount of energy that the tuner cables carry from the tuner back up to the radio when transmitting. It is this energy that can drive your computer crazy and make it do strange things. The kit contains everything you need - and no cutting of cables or soldering is required. Please specify make and model.
