[amsat-bb] grid squares and trip update

Hi all! Will be driving down to Nazca starting tomorrow. Potential grid activations include fh25 and fh16. The good news is that we should have wheels for the rest of the trip. This means fo-29 and ao7(I'll give it a shot both mode a and b!) morning and evening passes from the Morrow Solar (fh17lt). 73 es be good! Norm n3ykf
