Because 7040 kHz is the "RTTY DX" frequency in the ARRL bandplan.

Whoever designated 7040 kHz as a QRP frequency didn't look at the ARRL band
plan.

Have heard suggestions to move the QRP Calling frequency to 7030 kHz -- but
that probably has a lot of data stuff too
But suspect the QRP Amateur Radio Club International should do that URL:

Just was starting to get interested in QRP. Been making many contacts
with 1/2 watt on 7040 KHz. But lately it has been worthless due to all
the QRM from RTTY stations operating very close to 7040. Why? Why are
all the RTTY people meeting so close to 7040 when there is so much free
space in around 7090 area?
