Hi,
Here is the description of a small extension to the macro QSY:
At the moment, here is what QSY does:
<QSY:FFF.F[:NNNN]> qsy to transceiver frequency kHz, optional water
frequency Hz
The proposed fix is to add several frequencies and frequency ranges
instead of just one, like that:
<QSY:F1;F2;F3[:NNNN]>
... or, with frequency increments:
<QSY:F1+D1;F2+D2;F3[:NNNN]>
The increments D1, D2 ... represent frequency intervals, that is, a
shorter way to write:
<QSY:F1;F1+D2;F1+2*D1;F1+3*D1 ... F2;F2+D2;F2+2*D2 ... ;F3:NNNN>
Here is the new behaviour (Nothing being changed wrt NNNN):
* If the current frequency is smaller that F1, jumps to F1.
* If the current bigger is bigger that F3, jumps to F1.
* If the current frequency is in the interval F1-F3, jumps to the next
frequency, strictly greater than the current one.
That means:
* If only one frequency is given like now, nothing is changed.
* If there are several frequencies, it jumps to the next one each time
the macro is run. It allows to try a range of frequencies, and jumps
back to the beginning, simply by clicking the macro.
* If a macro tag <TIME:secs> is added, the macro will automatically try
all the frequency range, in a loop. The loop stops when clicking on the
waterfall. But can restart at the last freq by rerunning the macro.
What is it made for?
Simple example: Wefax emitters have several frequencies, but one cannot
know in advance which one will emit something. Dialing all of them is a
pain. Here, just by clicking the macro, you can test all freqs. Here is
the macro, which iterates on all frequencies of London Weather fax, with
5 seconds tempo:
<RIGMODE:USB><MODEM:WEFAX576><QSY:3853.1;7878.1;2616.6;3287.6;4608.1;4780.1;8038.1><TIME:5>
Another example: This macro tries all frequencies of the FM band. Now it
is possible to go from one station to the next just by clicking one
button (No temporisation):
<RIGMODE:FM><QSY:88000+200;108000>
The necessary code change implies about 200 new lines in the function
pQSY (file misc/macros.cxx), and should not break anything.
Any remark, idea or suggestion?
Thanks
Remi
