M/F = 100-1364 kc/s: H/F = 2700-14000 kc/s: Spark = 75-750 kc/s. |

POWER SUPPLIES |
|
MA/M = 1.25kW 75 c/s HT. MB/P = 1.25kW 500 c/s HT. |
|
RANGE IN MILES |
|
Maximum aerial power was rated at 150 Watts for M/F (to achieve a range of 175 miles): 50 Watts for H/F (to achieve possibly world wide coverage at times, but nominally 50 miles): Not given for Spark (but 12 miles was achieved). |

WHERE USED/FITTED |
|
Fit was across the board, but in few numbers, being found in Minesweepers, HMS Ganges, Whitehall W/T, Unicorn (RNVR Drill Ship), Australian shore stations and heavy ships (Iron Duke - battleship) for example, cruisers and destroyers, though for the latter two classes, a piecemeal fit.
A low/medium power set, it followed the convention of its day, namely that the set comprised of three transmitters, one Valve set for M/F, one Valve set for H/F and a Spark set, the transmitter 6D. |
