What is new in AMMAX3000?
- Robust output RF stage based on larger FET
- Robust PWM output stage based on larger FET
- Stronger on-board DCDC
- A number of small fixes and improvements
- Improved firmware (several LPF filters can be selected)
- Removed one trimmer for easier setup
- Support for Barix internet streaming with Mp3 playback backup
- CW jumper for CW operation

Technical specs:

- RF Output Power AM: ~10W carrier (24V-50V DC stabilised, use 50V for maximum power), varies with band and frequency
- Peak RF Output Power: ~60W (due to > 125% positivemodulation)
- Output connector: BNC
- Output Impedance: 50 Ohms
- Frequency Range (MW version): 540-1710KHz
- Frequency Range (shortwave version): 160m, 80m, 40m (other SW bands also available, please ask)
- PLL Steps: 1KHz
- Frequency stability: +/- 50Hz
- RF output: Harmonics: -50dB, Spurious: -80dB
- Power Supply: 48V/2.5A DC stabilised
- Wideband design, no tuning required
- Audio performance: compressor, low pass filter, limiter, treble, bass adjustment
- RF output ruggedness: > 2:1 VSWR
- Modulation: AM (CW input on-board. TTL 5V for disable)
- PCB size: 100x125mm
- Audio input: accepts either mono or stereo signal (transmission is mono)
- Audio connectors: 3-pins for GND, L and R signals. With audio input board you also gain XLR, RCA and USB audio input
- DRM support: On-board jumper can disable DSP processing which is great for DRM modulation
- Modulation: AM, >125% positive mod
- PWM circuit is opto isolated and can be used to drive high power external stage
