Further to above, there are no restrictions on whether you can or shouldn't use CW on 50.200Mhz.
Put out a CQ, and see if you get a response!
The International DX window (50.100-50.150MHz) always attracts very strong, and opposing, points of view.
Some people are of the opinion that any DX on 6M is DX and can/should be worked within the DX window, whilst others (myself included) think that is simply poor form. Working across to VK6, ZL and FK via Sporadic E aint real DX, and occurs like clockwork every summer, so there is absolutely nothing special about it.
The best way that casual "DXers" and the serious DXers can co-exist on 6M is to respect each other.
Easy said, but rarely done.
If you want to have a QSO with VK/ZL/FK then do it above 50.150.
How hard is that?
The ultimate disrespect is when it takes several overs on 50.110 before brains wake up and you'll hear "... maybe we should think about getting off the call frequency...".
Gee, what a good idea.
It should be an automatic procedure to QSY above 50.150 after initial callsign exchange within 10-15 seconds, but rarely done.
Welcome to 6M!
