Hello Andy, About very sensitive mode, you have also two specific modes (on "Multipsk" and "ThrobX" for the first) : * THROBX: Lowest S/N: -18,5 dB for the 1 baud, -17.5 dB for the 2 bauds * PSKAM10: Lowest S/N : -19.5 dB
They are below but not very far from JT65A (which has a lowest S/N of about -24 dB) and they are "relatively" much faster that JT65A 73 Patrick ----- Original Message ----- From: Andrew O'Brien To: [EMAIL PROTECTED] Sent: Friday, April 13, 2007 9:19 PM Subject: [digitalradio] The Great MT63/Olivia/Throb/DomicoEX/JT65A test I would like stations to test weak signal propagation and decoding characteristics , this weekend's conditions look ideal (i.e. propagation is expected to be poor on 20M and up). I would suggest that stations pair off and work each other via Olivia at first, establish the lowest workable power levels between the two stations using Olivia, and then switch to MT63 DominoEx , Throb, and JT65A. I suggest you use the same frequency for the tests, please avoid the standard JT65A frequencies (14076, 7076) . Always " QRL? " Please report your results here. Feels free to play around and add other tests if you like. Andy K3UK
