Dear David, I have done this only a few times just for a test, to see what can be done in an emergency. I know it is a bad idea to do it regularly, so I do it for test purposes and only when I want to convince someone (including myself) how good PACTOR 3 can be in an emergency. When the communications infrastructure of a whole country has gone down, this is the only way to pass digital traffic accurately and effectively. There is no other accurate way OM. If you only had a PACTOR 3 MODEM and an open mind you would understand what am I talking about. And if you ever get a little interference from another station, if there is no other way for the traffic to be passed, please be patient. The transfer will soon finish because it is a fast mode, it will not last all day just like many ragchew QSOs do. After all what is going to happen to you? Is the PACTOR QRM going to spoil your toys? Santa is here so you might get new toys OM. Not to worry. Life is too short to complain about PACTOR QRM all day. Get a life. Have a drink and you might feel much better! hi hi hi!!! MERRY CHRISTMAS and a HAPPY NEW YEAR. 73 de Demetre SV1UY
