Is anyone successfully using one of these? I want to copy RTTY tones direct from  a computer on it and have no idea how to get the RTTY to display as the CW does in in this downloaded photo. I asked the seller for a manual and he sent me one in Chinese - useless. This was fairly expensive and I would like to be able to use it 24/7 in a situation where a computer running MMTTY is too big and consumes too much power.
