You'll find me every sunday before and after DL0HV-QTC, Hannover.
DL0HV-QTC starts sundays always 10:30 local time on 28.780 mc/s usb.
DL0HV-QTC is transmitted from Lister Turm, Walderseestr. 100, Hannover.

Ten-meters-transmissions can be executed directly from there, or - taken
from VHF or UHF to put them on ten meters
by om Matthias, DL9MWE, Gross-Buchholz, Hannover.
Please watch 28.780 mc/s just before start of QTC to get more information
about ten-meters-transmission.
After DL0HV-QTC I manage circuit control and check callsigns of listeners
on this ten-meters-frequency of hams.
