[600MRG] 630 meters- 2 way by Slow data rate modes

[Andy - KU4XR]

WSPR-15 decoding today 1 hour - 40 minutes past Solar Noon near Knoxville, TN.

1400  -19  -0.6    0.475811    0   WG2XKA        FN33     30

1600  -36   0.1    0.475811    0   WG2XKA        FN33     30

1800  -32  -0.2    0.475811    0   WG2XKA        FN33     30

WG2XKA is 800 miles distant from me .. Copy is consistent today with every transmission decoding so far..
Daytime - Long distance 2 way communication using Slow data rate modes shows promise on 630 meters..
2 FSK possibilities are WSQ,  and JASON , a PSK possibility is WOLF ( requires precise frequency control,
and sound card sample rate ) ..
 
This is old news, but worth mentioning again..
