i’m looking for someone to help me design and build an am broadcast transmitter.
i have some old HF ham radio stuff as well as discreet components to work with for scrounging parts.
looking for DDS frequency synthesis.
PWM Modulation
Class D output (tube or solid state finals) adjustable from 0-10 Watt pep 0-2.5 Watt RMS.
Balanced 600 ohm audio input.
SO239 RF output
i’d like good filtering and low noise / distortion.
want it to do -99 +125% modulation.
built in modulation monitoring.
looking for resources on pwm coding and dds synthesizers.
like an external 10mhz gps clock input option.
i prefer to build with mostly the parts and components i have on hand.
looking to do something really fantastic to replace this not so fantastic carrier current transmitter i currently have.
