| ⚫ | The AN/PRC-77 has been replaced, as a main source of radio communication for regular forces of the [[Norwegian Army]] by indigenously developed radio sets called [[Multi Rolle Radio|MRR]] (Multi Role Radio) and LFR (Lett Flerbruks Radio) (Norwegian for Light Multi Role Radio), and a number of other modern radios. However the Norwegian Army did not throw these radio sets away. Instead many of them were handed over to the Home Guard which now uses it as their backup radio in most of their troops as there is only a limited supply of MRR sets for their 43 000 soldiers. |

The [[Austrian Army]] still uses the AN/PRC-77, though it seems as if it is only used for training cadets in radio communications. For border patrol the Austrian Army now uses a new device called "TFF-41" (Pentacom RT-405), which is capable of frequency-hopping and digital encryption. The Austrian Army also uses the AN/PRC-1177 for example the Austrian AN/PRC-77 have a special switch for a 25 kHz mode, which reduces the bandwidth of the selected channel by 25 kHz and therefore doubles the number of available channels. |

AN/PRC 77 Radio Set is a manpack, portable VHF FM combat-net radio transceiver manufactured by Associated Industries[1] and used to provide short-range, two-way radiotelephone voice communication.[2] In the Joint Electronics Type Designation System (JETDS), AN/PRC translates to "Army/Navy, Portable, Radio, Communication."
The AN/PRC-77 entered service in 1968 during the Vietnam War as an upgrade to the earlier AN/PRC-25. It differs from its predecessor mainly in that its final power amplifier stage is made up of solid state components and not vacuum tubes like the PRC-25. Also the PRC-77 has the ability to use voice encryption devices, while the PRC-25 could not. These include the TSEC/KY-38 NESTOR equipment used in Vietnam and the later KY-57 VINSON family. Problems were encountered in Vietnam with the combination as described in the NESTOR article.
Today the AN/PRC-77 has largely been replaced by SINCGARS radios, but it is still capable of inter-operating with most VHF FM radios used by U.S. and allied ground forces.[3] It was commonly nicknamed the "prick-77" by U.S. military forces.[4]
The AN/PRC 77 consists of the RT-841 transceiver and minor components. It can provide secure voice (X-mode) transmission with the TSEC/KY-57 VINSON voice encryption device, but is not compatible with the SINCGARS frequency hopping mode.[3] During the Vietnam War, the PRC-77 used the earlier TSEC/KY-38 NESTOR voice encryption system.
