Following info from DXNL:
Holger, DL1COP informs that Franz, DL3PS/HB9EHQ passed away suddenly and unexpectedly after suffering a heart attack at the age of 45.
Franz was member of the DARC, USKA, HB9VC and HTC and made several DXpeditions in
the past like LZ/DL3PS (Sofia), TF/DL3PS (Vestmanneyjar Island), TF/DL3PS (Grimsey Isl), ZS6/DL3PS (Vanderbijlpark), 4X/DL3PS (Ashkelon) and D44TXS (Cape Verde) during March of this year.
Several friends of Franz will try to confirm all open QSL requests (especially the latest
ones from the D4 DXpedition) with an appropriate remark.
