As of December 1944 the AAF started equipping all tactical fighter and bomber aircraft with the new AN/ARC-3 eight channel radio. This radio enabled all tactical aircraft to communicate with each other including light artillery observation aircraft and ground observation posts.
I am not sure which radios and frequencies would have been required in the L-4s assigned to artillery fire direction in order to facilitate communications with the AN/ARC-8 radio. There were a lot of changes in AAF radio equipment in late 1944 and 1945.
So in early 1945 the L-4s would have been able to communicate with all other tactical fighters and bombers if they had their frequency crystal installed and pre-set to one of the 8 channels.
I hope you find some of this stuff of interest.
