Tom KD0VBR and myself had a nice CW and then AM QSO on 1900 khz last sunday afternoon with both of us using nearly identical setups.  Communication quality was excellent.  Of course we are only about 15 miles apart.  Headphones required to block out the noise of the dynamotors.

Getting about 2 A of antenna current into a directly fed inverted L about 65 feet total length....about 200 W input ( ~1000 V at 200 ma ) power.
