First of all those you have visited, are not all of them.
There is multiple ones per map as it seems, and you just visited one per map.
I re-read the informations in the BFEE Discord again, and currently there are 3 radio locations known on each of the four maps. And even tho we don't know yet if these locations are all yet or if there are more.
Also we don't know if this EE is even supposed to be actually live to complete yet.
If you wanna stay uptodate on this topic and Battlefield EE's in general, i'll leave you the invite link here to join the official Discord channel > https://discord.gg/bfee
You can also find me there with the same tag, just ping me if you have any questions.
Greets,
Travis
