Noted Kevin, so my putting the radio in 9600 data mode the audio is now available from the discriminator directly. For some reason I am unable to decode the telemetry from AO85 and AO91 using a ICOM 821H and Signalink USB. Will try soon with an SDR as well. 73 Nitin [VU3TYG]

I will mention that for a Icom IC-9100 you need it in Data 9600 mode, the reason being that 9600 gives you the full bandwidth, in non-data mode the radio filters out the sub-audible tones.
