thanks for the logging and reception reports
but im just running well under a watt of power doing continuous testing.
low level modulation affords this ability to operate at very low levels of power without compromising the modulation level and allows real world testing at low power levels.
ive purchased new audio manipulating software in an effort to tweak and utilize as much amplitude modulation as possible with minimal distortion, maximum dynamic headroom, phase cancellation elimination and minimal compression but as anyone who is into this hobby as much as i am knows, its quite difficult to adjust and calibrate very good sound for AM with a bandwidth of 5Khz, tailoring this for weak reception but not overdoing it for strong reception, there is always a trade-off when dealing with AM broadcasting, when trying to squeeze as much flat response sound as possible into 5hz to 5Khz.
the testing is comprised of a remote SDR that is located 5 miles away from the transmission site, receiving the test transmission at a steady S3-4 simulating poor reception conditions with occasional noise and interference allowing me to calibrate and adjust the modulation as necessary.
as the saying goes, the better you can improve your modulation, sound and efficiency for AM, the better listeners will hear you during points of poor reception.
as i continue to test, the tektronix scope will record any thresholds crossed that i can correct later.
im quite the stickler for this
