SSB or CW
SSB - continuous voice modulation.
CW - Nominal PEP input of 100 watts speech. Third order distortion products at this level are at least e0 db down from signal.
70 watts
230 volts a-c ± 10%, 3-wire, single phase, at 7.5 amperes max, or 115 volts a-c ± 10% at 15 amperes max, 50-400 cps. Operation from a line frequency other than 50-60 cps requires an auxiliary 60 cps supply for fan motor.
52 ohms.
52 ohms unbalanced with vswr not to exceed 2 to 1 on the amateur bands.
40 db down from output signal with 1-kw single-tone input.
All harmonics at least 40 db down from output signal.
Type 811A triodes (4)
Model 351E-4 mounting plate (Collins part number 522-1482-003). This plate can be used when installing the 30L-1 in an airplane, boat, or similar location requiring a rigid mount. A luggage-type carrying case is also available.
