O.k ... let me explain why I asked the question for the sake of satisfying any
curiosity:
I have EchoLink (Ham Radio VOIP) connected to Jessie like this:
VHF Transceiver (with two interface cables going to the MIC and LINE-OUT jacks
on the back of an internal sound card. Incoming audio (radio frequency)
goes through the antenna ... through the transciever ... to the sound
card (via the MIC interface cable) ... it gets processed by the sound card and
stuff happens on VOIP ... Because the VHF transceiver is effectively turned into a
repeater NO transmit or recieve audio can be heard on the transciever itself
(as it should be).
In order to hear comms coming in or out of the transciever (via an antenna) one
has to connect to the transciever with ANOTHER transciever in order to hear
people talk (if you are tuned to the same frequency off course)
Now ... my second transciever is fitted inside my car ... in order for me to
hear all comms on the frequency I need to go to my car and turn that transciever
on every now and then which becomes a pain in the donkey ... ;) ...
In order for me NOT to make a trip to the car every 10 minutes I though of
splitting the LINE-OUT and add a normal set of desktop speakers.
So ... I was just wondering if I will have any losses (in whatever form) when I
"split" the signal ... keep in mind that the audio signals processed by the sound
card should be strong and reliable ...
Thank You
Danny
