Hello Gary,
I am not particularly familiar with the Signalink but it seems to have
the usual connections like AF-out, AF-in and PTT.
The TR7 is not at all uncommon in this respect. Keying is low-voltage
positive and the audio connections are not different from other
transceivers.
I used mine for WSPR without any trouble.
If nothing at all works you may want to check whether the GND connection
is good. At least PTT should work straight away.

I would like to give some diital modes a try, but I have not been
successful in connecting the Signalink to my(new to me) TR-7. I have
the jumpers set correctly on the Siglink, but I am not able to pick-up
signals on the waterfall (JT-65) nor am I able get it to key the PTT.
Can someone point me to a working connection diagram?
Gary, K6PDL
