Hi Stefan=2C
 =3B
three of the frequencies seem to =3Bbe the alternate frequency set= of the Alpha (RSDN 20) navaids=2C mentioned on
 =3B
F6 =3B 12500.00000 =3B Hz =3D 16 x 781.25 Hz
F7 =3B 13281.25000 =3B Hz =3D 17 x 781.25 Hz
F8 =3B 15625.00000 =3B Hz =3D 20 x 781.25 Hz
 =3B
There also seems to be another one somewhere around 12.75 kHz.
Best regards=2C
