I run my T-47/ART 13 powered by a DY 17 Dynamotour, and use a 560 Pf Large
Variable Cap hooked to the shunt connector on the antenna out insulator. On
3885, the cap is about 2/3 meshed, and D is at 15, C at 5 and E at 195.
This give little over 100 watts out on a bird watt meter, and little over 2
amps on RF amp meter. The antenna is a 250 foot flattop, up about 25 feet,
fed with ladder line. I use a large home brew balanced tuner, using the
Large 4 inch in Diameter B & W TV 1000 swinging link coils. The tuner is
fed via RG 213 coax from the transmitter. With that cap, the set loads fine
business on 80, 40, and 20 meters. I use a BC 348 from the dynamotour as
the receiver and use it weekly on a local AM net. I have found the RS 38C
mic to produce plenty of audio. For anyone interested, the net as at 12
noon EDT. The area is Greater Cincinnati, Northern Kentucky, and S. E.
Indiana. Check in from Chicago, and other outlying areas are quite common.
