Thanks for the reply AA4PB
I have the cables supplied by tigertronics and they connect through the 6 pin data port on the back of the 450d
I also tried with the jumper links even bought the slhead module instead of using jumper wires and it still wont work
I connected everything to the instructions and still no joy, the data cable is supposed to cut the audio out on the 450d but it does not and i get no activity in the waterfall on dm780 using psk31
But when i put the mono cable in the ext spk socket of the 450d to the spk socket in the slusb the audio cuts out on the 450d and then i get activity on the waterfall in dm780, i can adjust the receive signal by using the volume on the 450d but it still wont transmit.
I phoned waters and stanton here in the uk and the shop engineer agreed that it should not work out that way and said to send it
back to the shop as it sounds like the data cable could be faulty, i have sent it back to the shop so will see what happens.
I have done everything to the 450d, computer and slusb to the book and i was at the end of my tether, i expect a little difficulty but
this just took the biscuit considering it is supposed to be easy to set up
Hopefully someone with the same set up will help out here but i am lost to how it just refused to work
