When coupled to the R1155 this produces a cardioid pattern. Two out of the three rectangular, steel cased caps were open circuit, so again I had to gut and re-stuff them. The receivers in particular were a popular favourite with hams and shortwave listeners in the period following the war and are still collected by enthusiasts. On the left are the two Bomber Command types, the T1154B & the later T1154M and on the right the High Speed Launch type, the T1154L. weblink

There was evidence of re-aligned and bends in the top of the screening cans suggest that the valves had been out on more than one occasion. Well done. Although I'm a TV man now, I would quite like an R1155 project........ This may have to be adjusted later when the strength of the homing signal changes.

Although they were used mainly in aircraft, later in the war they were fitted to small boats (N suffix), and also to vehicles (115, 115B, 130, 131). The R1155 and T1154 sets were manufactured by several British radio manufacturers, including EKCO, Marconi, Plessey, and EMI. T1154 Transmitter For Sale Set the loop "athwarthship" (ie to a zero scale reading) and ask the pilot to alter course until the needles intersect on the centre line.

One wiring error was a reversed voltage divider and the other connection of the magic eye to the AF rather than the RF volume control when not on AVC. I have revised the text in a few places, included all the corrections listed below spotted by readers and myself. The VMARS copy of the AP2548A official manual for the T1154 in PDF format.

Electrical restoration involved changing a considerable amount of crumbling, rubber wiring, which apparently is a common problem with these sets.

None of the circuitry had been removed or modified, all the removable shields were still present and the rubber-insulated wiring was still in quite good condition. I identified each end of a wire, removed it, replaced it with cotton covered wire, and marked it off the circuit diagram. This control makes the cardioid pattern sharper. check over here Page 2 - gives general specifications of the R1155.

This is largely just additional measurements of the HT+ to ground and HT- to ground resistance values that change with different positions of the Master Switch AND Band Switch. R1155a Receiver The case and front have been repainted in view of the amount of missing paint and corrosion. Particularly if it was interesting, unusual or challenging.
