Are there any AN/PRR-9, AN/PRT-4 produced after the Vietnam era?

[Eugene]

Hi guys, as the title says, I want to ask if there are any AN/PRR-9 and AN/PRT-4 that were produced after Vietnam era? All the ones I have are dated before 1973, even some of the lighter olive green ones are just refurbished pieces from old pieces made from the Vietnam era. Does anyone know how long these are produced? Since the only items from these that I've come across that were made after 1973 have only BA-399/U and BA-505/U. And since it was refurbished in the 80s, I wonder if it was used in any other wars or aided in wars like Grenada or Panama?

Please let me know if you can, any help would be appreciated, I'm from Vietnam and sorry for my bad english
