Narrative:

I departed in IMC with clearance from a mountain airport at 2;100 ft and was cleared to climb to 3;000 ft and contact 121.25. On climbout; I attempted to make radio contact at least 3 times with no success. Meanwhile; I was dealing with an autopilot recycle and fighting some crosswind turbulence that caused me to get on a 270 degree heading which was not correct for the VOR that was my first checkpoint. Realizing I couldn't make contact on 121.25; I went to 125.4 (the usual contact from this airport) and informed them of my situation. They told me to stay on the same heading and shortly afterwards; issued a terrain alert and an immediate climb to 5;000 ft. On or about that time. I requested a direct routing to my next waypoint that was at about 240 degrees; which they allowed. All of this occurred in IMC. I was told to call the controlling agency on landing; which I did. After relating the situation; I was informed that they gave me someone else's clearance! (For an airport that is 33 miles south of my departure!) I should have been suspicious of such a low altitude clearance and a contact frequency that is normally used south of my area.
