[Ham-Mac] Looking for SL1+ and iMic users

[Steve Hellyer]

Hi Dick:

I am using the iMic here with my TS-2000 via 13 pin accy. port and the 
SignaLink SL+.

I have not used a TS-570 but perhaps some of my experience will help?

I did not have to adjust the SignaLink audio out from radio to the 
computer but I did have to jack up the TX side a bit to trigger the 
transmit without having my Mac at full volume.  60 to 70% is a good 
level I have found from my Mac to cause the SignalLink to Key up.

Make sure you the switch on the iMic is set for microphone level input 
rather than line level (strangely switch position is away from 
microphone jack). I fined that work best as it much more sensitive. 
Easier also when I want to switch to from SignaLink to a regular 
microphone for use for EchoMac or other audio input.

Not sure if this applied to the TS-570 but, the SignaLink SL+ is only 
wired to get audio from the Main VFO not a Sub-VFO.  You will have to 
rewire the connector to change that.  I emailed Tigertronics about this 
as it wasn't very clear.....

So if you have been trying to get audio from a Sub-VFO you won't unless 
you make some cable mods.

If your using Mac OS X check to make sure audio is coming in using 
built-in system tool "Audio MIDI Setup " in the Utilities folder.
You can adjust input level and out put levels and set for 16 Bit 44.100 
Khz. The normal sound panel in Systemn Preferences  work nice as well 
as you have some feedback with a bar graph as to audio level.

I plugged in a microphone and just set my levels that way.  Once 
confident the Macintosh was hearing audio from standard microphone I 
then I connected the Signalink (Mic to Mic, Spkr to Spkr - I have mixed 
these up many times until I label by cables :-), tuned to some busy 
freq.  and adjusted the TS-2000 audio output (AF) levels of the accy 
port (one of the menus in the packet area as I recall).

Hope some of this is of some help.
