• Notes
• Wireless Set No. 19 Mark I: single band transceiver used for communications between armoured vehicles and later general use; comes with three functional units in one cabinet: A set (shortwave communications), B set (VHF near range communications), on-board intercom. A set: AM (1,5 - 2,5 W), MCW and CW (3 - 5 W), covers 2,5 - 6,25 MHz in only one range, two mechanical presets with quick change arrangement ("Flick").
  B set: VHF (telephony, 0,4 W) in the range 229 - 241 MHz. Pye introduced the W.S. 19 MK I transceiver in 1941, because of the frequency coverage of the A-set appeared to be too narrow, the MK II was introduced in 1942 with a coverage 2,0 to 8 MHz, split in two ranges. Later a special dial knob was introduced for easier tuning, which came with the Wireless Set 19 MK III, but was often mounted on the MK II sets.
  A RF linear amplifier was introduced in 1942 to increase the set's range, it's output power is 10 - 14 W telephony and 25 - 30 W CW, the installation of a Wireless Set No.19 and the Amplifier RF No.2 is referred to as Wireless Set. No.19 HP (High power).
  Wireless Sets No.19 with very similar appearence but slightly different circuitry have been produced in Canada and were shipped to Russia as a part of the Leand Lease Act, these carry english and cyrillic lettering.
