PTC116 Reporter |
. |
One of the early VHF radios used by the Police was the PTC116 "Reporter", made by the Pye company in Cambridge, UK. The PTC116 was a single channel AM radio producing 2.5 watts of power in the 60-100 MHz range. Introduced to the New Zealand Police in 1952-53, the Reporter replaced the earlier Pye boot mounted radios which had been installed in 1948 Chevrolet Fleetmaster patrol cars in 1949. At this time police radio communications consisted of a simplex system operating at a frequency of 77.5 MHz, (very close to the present police VHF frequencies) |

Base transmitters at Mt Eden (Auckland), Cashmere Hills (Christchurch) and the 2ZB building on Mt Victoria (Wellington) were connected to the central police stations by land line. These high sites provided communication within the city areas between cars and base, however car to car communications were marginal over anything other than very short distances due to the low power of the car radios. These radios remained in service until the early 1960's when the police moved to the 40MHz band.
