RTTY notes on 20 m

On many occasions when listening on the amateur radio bands I rarely hear a complete exchange on digital modes.

Case in point, around 21:30 UTC K4ADR (Florida USA) comes in on 14088 kHz with -85 dBm signal power, and makes the following contacts:

• SP4EOO (Poland)
• SP5ECC (Poland)
• RW0LIF/6 (Russia)
• AD2Q (USA)
• OZ5NJ (Denmark)
• DG4NAT (Germany)
• IZ1UJM (Italy)
• SQ7EQB (Poland)

And I only know because K4ADR copied back those, except for DG4NAT whose reply I did hear, and maybe a IZ0PMV that was later on another frequency.

Maybe I'm just not on beam and all those operators have directional antennas pointed towards Florida. Or maybe I need even more gain than I already have, but that's not going to happen any time soon.
