Frequency coverage: 3.5–29.7 MHz, covering all amateur bands. By retuning the input coils as necessary, the following general coverage bands may also be covered:
Band Total Coverage
3.5 3.4–5.0
7.0 6.5–9.5
14 9.5–16.0
21 16.0–22.0
28 22.0–30.0
Mode: SSB or CW
Service:
SSB – continuous voice modulation
CW – 50% duty cycle (key down not to exceed 30 seconds)
Power input:
CW – 1000 watts
SSB – Nominal PEP input of 1000 watts with speech. Third order distortion products at this level are at least 30 db down.
Drive requirements: 70 watts
Input impedance: 52Ω
Output impedance: 52Ω unbalanced, VSWR not to exceed 2:1 on amateur bands. N-type connector.
Noise level: 40 db down from output signal with 1 kw single-tone input.
Harmonic output: all harmonics down at least 40 db from output signal.
Tubes: (4) 811A
Power:
230 VAC ±10%, 50–400 Hz, 3-wire, single phase, 7.5 amps
115 VAC ±10%, 50–400 Hz, 15 amps
Note: Operation from a line frequency other than 50–60 Hz requires an auxiliary 60 Hz supply for the fan motor.
