Lately I have noticed more rtty working around 7.035 and up to 7.045 of 40m which covers up the QRP calling frequency of 7.040 for cw. I thought that the digtal guys worked higher up the band at around 7.065 up to 7.100. Is this the norm or are the digital guys mad at us for when we run our cw contests?

This is a major problem, but it is not the CW QRP or the RTTY operators fault.  7.040 is the CW QRP calling frequency but it is also the RTTY DX frequency.  Go figure that one out.  

The RTTY DX feq of 7.040Mc is in the ARRL band plan while the CW QRP calling freq is in the Gentlemans agreement.

This is the ITU region 1 band plan for 40meters:
7.000 - 7.035 cw only
7.035 - 7.040 * digimode except packet, sstv, fax, cw
7.040 - 7.045 digimode except packet, sstv&fax, phone,cw
7.045 - 7.100 phone, cw

You can see that if the US wants to work DX on 40m digital it will be between 7.035 and 7.045

I can realy feel your pain on this one since I am a big CW and RTTY fan.

As always if the freq is in use don't transmit there.

7.035-7.045 is the digimodes sub-band here in Region 1 (7.000-7.035 CW only, phone from 7.040 up).

There might be a chance of some reallocation when we get our lovely new shiny 100kHz on 40, but even though the RSGB are saying we might get access to 7.100-7.200 here in the UK as soon as October, I wouldn't count on that new spectrum space not all being given over to SSB :-(
