North American Traffic & Awards Net

Yesterday evening was the first time I checked into the net, 7.186 around 0030 UTC and I throughly enjoyed the laid back format.
One of the relay stations helped me out and I wrote his call down incorrectly. KW4CSL is the call I noted, we also gave each other signal reports around 0050 UTC. I gave him a 5/9 he gave me a 5/7. I need the correct call sign.

Also with regards to mobile operation, if I am at home, sitting in the pickup, not moving, does this still make me mobile?

Thanks Alan K4LFP
