Dear all,

I added AFSK function to TX500.
As a result, WSPR-2, WSPR-15, JT9-1 and other AFSK signals become able to use in TX500.
The permission frequency shift width is small.
To producing AFSK signal applicable software and a PC are necessary.

And, I become able to use a mode at long time more than QRSS30 by using TCXO in substitution for X'tal of 6MHz of TX500.
OPERA beacon is available in keying of PADDLE Jack, too.

The person with the interest look at this.

Thank you. JH1GVY Mori

Completely awesome. Being able to quickly shift the frequency makes a number of modes possible. It should even be possible to send PSK31, or JT65. I'll look into this more.
