@kelbot The Motorolas won't take AA/AAA, but a number of FRS or GMRS would. To get similar range, you would need a 5W GMRS radio and one easy-to-obtain GMRS license. https://old.reddit.com/r/gmrs/comments/uodbt1/so_im_fairly_new_to_radios_i_just_received_my/ has some recommendations. I haven't used it, but that Radioddity GM30 looks like a decent deal; 5W for $40 (not sure about the bat situation). 3/
