The screen in transmission : a small blue logo shows the mode in use

The screen in reception of a signal "SIM31" the green logo " REWIND " becomes purple and indicates PSK31, a bug? It is really a signal "SIM31"

To go into mode SIM63, click right button on the vertical cursor, the color changes to white. When you click left again you go back to SIM31Every mode change is notified on the screen.

Of course, all these functions are the same for modes PSK31 and PSK63

I don't think so... The signal is probably saturated, the eye diagram doesn't show the straight losanges as usual, hence this hesitation of squelch to display something

Here is an extract of my log

Yes with NC5O, we made tests on on four bands 30/09/2012; propagation was with us

I would like to tell that I work with Signalink on USB port .The setting "Inp Vol" was always too low as you can see on the screen-shot, but despite that, it was decoded .

Nizar, who conceived the software SIM-PSK has found the solution in TiggerTronic's datasheets. I just had to open my Signalink and put a Jumper JP2 behind the marked button RX 2

You can see on the next picture how was improved the level "Inp Vol" ; furthermore I can now control the reception by the RX button of my "Signalink". The cursor must be approximately in the middle.

For our tests we have found ourselves on http://www.obriensweb.com/sked/index.php?board=digitalradio
