  • Bemerkung
  • Wireless Set No. 49 (later designation C40/B40): SW/VHF transceiver for vehicle or ground station use, it came in two parts, both together made up exactly the space of one Wireless Set No.19:
    Wireless Set No.49A (C40): frequency coverage 25 - 38 MHz (130 channels with 100 kHz spacing, three frequency presets), FM (F3), pout 15 Watts, range around 10 miles; intended to be used for general purpose communications.
    Wireless Set No.49B (B40): frequency coverage 38 - 42,15 MHz (10 channels of which four (A-D) common with four channels of Wireless Set No.88A, four (E-H) common with the four channels of Wireless Set No.88B and two channels for inter-AFV communications with other Wireless Set. No.49), FM (F3), pout 0,4 Watt, range around 2 - 4 miles; intended to be used for narrow range inter AFV communications.
    The complete Wireless Set No.49 arrangement consists of the A and separate B set and a power supply, all sealed and tropical proofed with recessed frontplate controls.
    The development for a successor of the popular Wireless Set No.19 started in 1943 with the W.S. No.X39A, it has been suspendid in mid 1944 and abandoned in 1945, when it became clear that FM mode operation in the VHF band will become new standard for narrow and middle range military communications.
    Development of the new Wireless Set No.49 started again in 1946/7 and prototypes became available in 1948 and tests were conducted in 1949 with the sets renamed as B40/C40. Shortly after, the more promising C42/54 and B45/47/48 sets later known as the Larkspur range of sets replaced the B40/C40 arrangement in the mid 1950s.
