The P4dragon DR-7800 is a no compromise HF modem that outpaces products 3x the price. The Dragon line of modems are for people serious about their data. You can add Class 1 BlueTooth (BLUE) wireless to this standard (STD) USB model for a wireless connection to your computer (DR-7803 Bluetooth).
The 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.
