Signalink usb and UISS for 9600 baud packet
I am running an Icom IC821H transceiver and the Signalink usb along with UISS software running the UX7HO High speed packet modem. However I can't seem to get this system to decode 9600 baud packet on falconsat-3 or Elfin A or B satellites. Is anyone using this combination to decode or send packets through the Falconsat-3 digipeater on 9600 baud ?? I have tried varied jumper wire settings on the Signalink and can send and decode 1200 baud packet with no problem. When trying 9600 baud the radio is set for 9600 baud using SET Mode but it still will not decode 9600 baud packets.. Anybody out there have an answer ?? Thanks JACK KC7MG
Hey Jack!
9600 baud packet requires something in the area of 15k of audio bandwidth to work properly. While I've heard from some folks that they've been able to operate 9600 with a Signalink, here is the spec. from Signalink's website:
------ Audio Freq Response: Approx. 300Hz - 3.3Khz @ 600 ohms ------
... so, as you can see it's perfectly suited for thinks like 1200 baud packet or anything else that uses the traditional voice range up to 3k (audio), but it's just not the "right tool" for 9600.
The other factor is the radio - for anyone else reading this, please be sure to use a radio with a 9600-capable DATA port. For the same reason that the Signalink's audio bandwidth hampers operation at 9600 baud, on the radio end of the connection you need a DATA port that works above the 3k audio range.
Your computer's sound card might be fine but if you'd like to have a dedicated sound device for interface to your radio's DATA port, I've had great luck with this item:

I used to have a Icom 821H wired with signalink USB to the data port on the radio (radio set at 9.6K baud) and worked fine for Winlink . 73 Nitin [VU3TYG]

Alex, You need unfiltered audio out from your radio. Singalink won't work.
I am not familiar with the IC821H but you need to tap the 9600 baud output and feed it directly into your computer's sound card. Best to use the UZ7HO free software modem. Take a look around the internet there are many write-ups on how to do this. 73, Adrian AA5UK

Adrian: The IC821H has unfiltered audio out of the data port which I did feed to the Signalink and used the high speed UZ7HO modem. Still didn't work !! Maybe that is the answer... feed the audio direct to the computer and bypass the signalink ?? I will try that, Thanks a lot 73 JACK KC7MG
