Dear all,


Beta-release v0.9.20.0 of SlowJT9 has been uploaded, see http://www.472khz.org/SlowJT9/.

Changes:

- Soundcard sample rate changed from = 12000 Hz to 48000 Hz.

- Alert function added (i= ncluding UDP broadcasting).
This function allows to genera= te an alert when a received message meets certain criteria. One or more of = following criteria can be selected:
* Your call is received.<= /span>
* A new call is received.=
* A new DXCC is received.=
* A new US state is recei= ved.
* A DX station (more than= xxx km) is received.
* A new DX station (more = than xxx km) is received.
* A call from the include= d list is received.
In case of an alert:
* The DTR or RTS pin of a= serial port can be set high. This can be used to trigger an alarm.<= /div>
* A UDP message can be br= oadcasted. UDP messages can be copied on any device (computer, tablet, smar= tphone) within the same LAN.
I did also write= a small app named SlowJT9_Monitor that can be used to receive and display the UDP messages on another computer.

- A Front End Mixer added= :
The resampling and decoding pr= ocess limits the maximum RX audio frequency to 4980 Hz for JT9-1, 2240 Hz f= or JT9-2, 840 Hz for JT9-5 and 415 Hz for JT9-10. This can be inconvenient if a higher RX audio frequency is nee= ded to fit the signal in the passband of a narrow filter.
This can be fixed by using the= Front End Mixer that downconverts the incoming audio signal (fOUT =3D fIN - fLO).
E.g.: if you want to downconve= rt the 1200 .. 1400 Hz incoming audio to 400 .. 600 Hz the local oscillator= frequency must be set to 800 Hz.​

Bug reports, remarks and suggesti= ons are welcome.
