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."
There were no changes to the external controls or looks, so the two radios looked and the operating controls were the same. The equipment tag glued to the edge of the front panel being the only (external) way to tell the difference. The original batteries had a 3 V tap (series diode-reduced to 2.4 V) for the PRC-25's tube filament. This remained unchanged so the batteries could operate either radio it was placed in, but the PRC-77 did not use the 3 V tap at all. With the more efficient all-transistorized circuitry, and without the DC-DC step-up voltage converter for the tube, the common battery lasted longer in the PRC-77 under the same conditions. "OF THE TWENTY-FIVE (25) ELECTRONIC MODULES ORIGINALLY USED IN BOTH THE TRANSMITTER AND RECEIVER PORTIONS OF THE AN/PRC-25, ONLY EIGHT (8) OF THE MODULES USED IN THE AN/PRC-77 ARE INTERCHANGEABLE WITH THE AN/PRC-25.'"

Today the AN/PRC-77 has largely been replaced by SINCGARS radios, but it is still capable of inter-operating with most VHF FM radios used by U.S. and allied ground forces.[6] It was commonly nicknamed the "prick-77" by U.S. military forces.[7]
NSN:5820-00-930-3725PART NO. RT-841/PRC-77NOMENCLATURE: RECEIVER-TRANSMITTER, RADIO DESCRIPTION: Radio RT-841/PRC-77 is a man-pack, portable, frequency-modulated receiver-transmitter used to provide short range, two-way radio-telephone voice 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 does not use vacuum tubes. The AN/PRC-77 can use voice encryption devices which the AN/PRC-25 cannot. Today the AN/PRC-77 has largely been replaced by SINCGARS radios, but it is still capable of inter-operating with most VHF FM radios used by U.S. and allied ground forces.[3] It is commonly nicknamed the "prick-77" by the U. S. Army and U. S. Marine Corps
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 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 main radio in most of their troops.
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", 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.
26 July 2002 - When doing testing on the 2577BA using an Electronic Load I compared the Energizer E95 Alkaline, Rayovac renewal and the BA-4386. (I'm waiting for the Radio Shack 23-519 NMH cells to charge). It turns out that when the BA-4386 is loaded with 1 Amp on the 15 Volt section the output is lower than when it is tested at 1 amp after a load of 3 amps for 20 seconds. Applying a heavy load to the BA-4386 activates the chemistry better than a light load, like that of the PRC-25 radio.
I have a limited quantity of the newer PRC-77 squad radios. Like the PRC-25, these radios tune 30-75.95 MHz. FM in bands 30-52.95 MHz (Lo) and 53-75.95 MHz (Hi) with 50 KHz spacing. RF power output: 1.1 to 2.0 watts; 150 Hz squelch. Because the radio is all transistors it only requires 12 to 15 volts for operation that is supplied by a battery (NOT INCLUDED) or the AM2060A. The radios have contract dates anywhere from 1975 to 1981. These radios are complete have been realigned and tested, and are guaranteed to meet or exceed their original specifications. The radios are in good condition with no major dents or gashes but the paint may be chipped and scuffed. The insides are guaranteed to be clean and free of corrosion. There may be unit markings in black paint that is easily removed with lacquer thinner if you desire. Each radio is equipped with a battery box, but the color of the paint on the battery box might not match the color of the paint on the radio. These radios are being sold with a money back satisfaction guarantee. If you are not happy with your purchase you can return it within 10 days for a refund of the purchase price. PRC-77 Used, guaranteed, $ 399.95 plus actual shipping.
To operate this radio you will need a handset and a battery and antenna. (sold separately). to email me your shipping address so that I can provide you payment information. HURRY! ORDER NOW, QUANTITIES ARE LIMITED! DON'T MISS OUT ON THIS OFFER. For accessories like handsets, antennas etc. for these radios CLICK HERE. NOTICE: These radios operate on frequencies that require a FCC license. It will be the responsibility of the purchaser to obtain the proper license and operate on the proper frequencies. I am not to be held responsible for improper operation.
