Anyone creating an Arduino controlled AF/RF signal generator with selectable (and hopefully calibrated) output levels??
There are many Arduino based VFO designs that fit the bill for the base for such a project. If you add a little bit of level control and some modulation choices, then these Arduino VFO's can become a basic piece of test and alignment for the homebrewer or income-limited amateur.
I had to borrow an HP sig-gen to align my HF radio's s-meter for instance, as it needed a signal source of 50uV/-73dBm and 0.8uV/-107dBM. Would have been nicer to build my own! Maybe a display to show the freq, modulation type, uV and dBm.
