NB I have since had an opportunity to check what transceiver chips have been used with the option card I have been experimenting with, and they've turned out to be the Zywyn ZT3243F, specified for up to 1Mbps, so no surprise they eventually gave up as the rates I have tried increased, and quite interesting it was only at 4Mbps that they did it.
