It really works!!  Time owned: 6 to 12 months
This really IS an amazing device! It makes SSB sound like FM! It's hard to describe but it really works! The only limitations is that it needs a strong and steady signal in order to decode the digital data. You've really got to "see" it to believe it! Yes, I also have the SSB option but haven't had a chance to try it out yet!

Itís not often that a new device entering the amateur radio marketplace represents a giant leap in the future of the hobby. The AOR ARD9800 Fast Radio Modem is such a device. Take a reasonable transceiver and aerial, tune-it to a data portion on, say, 20 metres USB, establish a normal analogue conversation with another station having the same unit and then click the digital switch of the ARD9800ís transmitting station. A word of warning is required here to the receiving stationÖ do ensure the operator is securely strapped-down in their shack chair, because if they are not, they will get literally completely blown off-it. Put simply this is jaw-dropping, mind bogglingly, absolutely amazing! Thatís a lot of adjectives for a small, very expensive box, but what exactly does it do? Itís sold as a high speed radio modem, but effectively itís a way of getting digital voice transmission over sideband HF using the standard 2.3khz voice bandwidth. The unit compresses and gives the equivalent of a 3khz voice bandwidth. The results are staggering. All the standard frequency shifted HF sideband voice qualities with fading simply vanish and are replaced with a near VHF FM quality. If you have regular HF contacts with the same folks, grit your collective teeth, dust off those credit cards and each purchase one of these babies. HF telephony will never be the same again.
