Very interesting, Andy. I had not noticed the RX RS ID button on the SDR
window or the RS ID configuration window.
Patrick,
Is there a way to keep the RS ID window open while using the RX/TX screen? Is
there any other notification of the RS ID detection when using the RX/TX window?
The MultiDEM program looks very nice. It has more functionality than the
built-in SDR front-end but it doesn't appear to have the RS ID decoding option.
Is that a possible addition in the future? Is there an advantage to the
built-in SDR function such as latency, etc.?
I am still puzzled about the Global Level reported in the SDR screen. Mine
still shows 0.0% to 0.1% although the decoding seems to work fine and the
receiver noise is visible on the waterfall. The input levels on both computers
are set to maximum. I tried boosting the input with microphone preamps but it
had no effect. The sound card on one computer is a Soundblaster Live! 24 bit
External and the other computer has an M-Audio Delta 66. I noticed Andy's
screen shows 10.8%. It doesn't apear to be a problem but I am wondering what I
am missing in the settings.
