If you are wondering what digital mode to choose (scotty 1, scotty 2, martin 1, etc), then it is regular pratice to reply in the mode a station calls or replies to you. The scotty 1/2 and Martin 1/2 are mainly used and differ in time [somewhat less or more then a minute] and thus in quality.
In busy/QRM situations it sometimes helps to go faster, and for instance use B/W 8, that only takes 8 sec. If you receive only faint signals it is better to use the modes that take more time like martin 1 [114 sec], scotty 1 [110 sec]or even scotty DX [269 sec] 73's de Marc, PD4U _________________________________________________________________ Express yourself instantly with MSN Messenger!
