dear patrick is it possible to put the dial frequence in the log??? would be a way to auto upload the spotted callsigns to a cluster or something like that greetz dg9bfc sigi

If WSPR is able to detect of -25 dB, the Call ID is only able to detect -13 dB signals (it begins to decode from -18 dB but not below). However, as WSPR it is a free-error transmission. As it is short (3.3 s), it's much more to introduce oneself (Call sign + Locator). It could be used for beacons alone or to test a mode (Throbx, Olivia) inside a sequence... in this way: <TX><CALL ID><RS ID> CQ CQ CQ CQ CQ CQ DE F6CTE F6CTE +K <RX> The program switches to TX, sends the Call ID then the RS ID (to make switch the other Ham to the desired mode ) and a message. Afterwards, the program switches to RX. The other Ham must leave RS ID and Call ID buttons pushed. Note: the Call ID structure is fix now, but there are still some small bugs. 73 Patrick ----- Original Message ----- From: "Andrew O'Brien" <k3uka...@gmail.com> To: <digitalradio@yahoogroups.com> Sent: Saturday, December 20, 2008 3:49 PM Subject: [digitalradio] Caller ID in Multipsk > The caller ID function in the latest test version of Multipsk works > very well.
