Neil made a very interesting observation a few messages ago about looking instead at the efficiency of the part15 AM transmitters. Modulation over 100% like the old Pan Axis AM 100 offered, and a more efficient use of the 100 mW we have to work with really seem like effective goals.
I had an AM 100 and it was really LOUD. When the Hamilton Rangemaster was first available Keith sent out some info to the effect that the benefit of his XMTR was in it’s better efficiency, more effective use of the 100 mW available.
Keith’s approach is likely proprietary, but I was wondering what some general approaches might be to improved modulation and better transmitter efficiency.
Experimental broadcasting for a better tomorrow!
