Weak signal after flashing

[gokudre]

Ive tried multiple roms from diff cooks. While they are great for many things including faster speed and more free space, im having one constant problem ..... no bars. I have the samsung omnia 1910 from verizon. Around here verizon is king in terms of cell reception. Before flashing i had full bars most of the places i went. Now im getting dropped calls. Before i flashed i didnt even know what my phones "dropped call" alert sounded like. Now i know it well. Is there a fix for this? is there a separate rom flash for just the radio? are there any other tweaks to boost my signal? ive search throughout the forums for days. It seems like HTC has tons of support but samsung doesnt get any love....=( im begging for some assistance here!!

thanks in advance!
