The AN/GRC-9 in the Dutch M38A1.

The Angrynines were used between 1950 and 1970 by the following Dutch armed forces units;

By the Army for administrative and logistical nets within the brigade at company and battalion levels. Also the infantry division commandos and warning nets
used this type of transmitor.

- During the actions in New Guinea in the 1950s and 1960s.
- By the Dutch forces in Suriname TRIS.
- 1953 as communication set during the flood disaster.

By the Navy and the Marines (where the GRC-9 was used untill 1985)on the dive vessels Nautilus and Hydra as the main communications set, on board of the large ships as communications set for the landing divisions and as emergency set for the ships communications in case of total power outage (called "Zwart Licht" or black light).

- During the actions in New Guinea in the 1950s and 1960s.


The Angrynine can be used as a stationary, portable or as mobile unit. It was used for radio, telephone and telegraphic connections in the 2-12 Mc band. The Angrynine can utilize the following power sources, vehicular generated power, the PE-237 or DY-88/GRC-9, and in ground use the hand generator GN-58 and the battery BA-48.

The Angrynines were also used during combat actions in New Guinea during the 1950s and 1960s.

During a foot patrol, generally, 3 men where needed to move the transmitter and it’s accessories. One man for the transmitter/receiver, a second man for the hand generator and a third man for the case with accessories such as the antenna reel, signal key, rope reel (to stretch the antenna), cables for the connection between hand generator and transmitter/receiver, ear-phones and the instruction manual.

Suffixes behind the model number (i.e. AN/GRC-9A/B), indicate the type of components included in the set. The installation of different components, different models, or different countries of production will change the model's suffix. For example, the hand generator GN-58-A a newer implementation of the hand generator GN-58, and the power units Dy-88/Fr and DY-88/GY have been fabricated respectively in France and in Germany.

The name AN/GRC-9 means, AN (Army/Navy), G (Ground, general use), R (radio), C (Communications) and 9 is the serial number.


The AN/GRC-9 was fielded in the late 1940s and used through the Korean War and later in the 1950s. The AN/GRC-9 replaced the SCR-284, SCR-288 and SCR-694 radios and was in turn replaced by the AN/PRC-62 and AN/PRC-74.
Two radio sets, the AN/GRC-87 for field use and the AN/VRC-34 for vehicular installation , have been adopted to replace radio set AN/GRC-9 which has been declared limited standard. The AN/GRC-87 and AN/VRC-34 basically are adaptations of the AN/GRC-9. Training requirements for these sets are substantially the same as the requirements for radio set AN/GRC-9

The GRC-3030 is the Dutch replacement for the Britsch WS-19 set's, round 1955 designed and build by the company "van Heem". The GRC-3030 was used by the Dutch army during 1958s and 1970s, thee GRC-3030 uses the same frequencies as the GRC-9. Both radio's were used together, the GRC-3030 has the nickname the Dutch Angrynine.
