With increasing of number of clients and good propagation I can see a problem on 10147. My QTH is in north of Italy and I can heard IS0GRB, SM0RWO, PI4TUE, DL9YCS and, sometime, more servers. My TX power is now 20W and I can connect to all the above servers. Each server don't hear all other so I get beacon, QSL and other response overlapped. When connected with a server, last evening with IS0GRB, a transmission from another server switch Fldigi from PSK500R to PSK125R and I lost a partially overlapped transmission from IS0GRB. Correctly this server re-transmit last info but with a PSK250R RSID. And in this re-transmission there was another server TX, Fldigi lost to switch to PSK250R and so on. Finally I get a connection with THOR for a good link that was working at PSK500R speed. Is this correct? Is correct the choice of a "standard frequency" for beacon, QSL and connect mode?
