Frequency: 10m SSB/FM; 2m FM 438,95 MHz (Relais Kahlenberg) for coordination.
QTH: Wien Donauinsel (JN88EG60CH)
Operator: Gerald OE1GPA/1
and Karl OE1KHU/1.
Device: Yaesu FT 817nd (AKKU 12,5V; Transm. Power 5 Watt)
plus amplifier 10m 100W
Antenna: 10m Dipole, HB9CV
10m Dipole was quickly tuned manually with VSWR meter
10m Dipole principally worked well but only two local QSO
HB9CV has VSWR 3 as at my home QTH
also Karl's 2m HB9CV has bad VSWR
10m Amplifier for FT-817nd worked without problems
20Ah Akku had even at the end still 12,5V
my special bamboo mast is a good idea concerning weight but
has to be redesigned a little ;-)

U P D A T E 1:
Outdoor measurements were repeated with help of OE1DGW.
Near ground the bad results of vertical positioned HB9CV were acknowledged but positioned 3m above ground and more
VSWR was better than 2.
(Equipment used: FT-817nd @5W and Diamond SWR-meter)
U P D A T E 2:
I repeated the indoor measurements of VSWR with my 2m HB9CV with following results
(Equipment used: FT-7800 @10W and Diamond SX600):
Vertically between 3 and 4.5
Also the hint to pay attention how feedline is lead out of the antenna influenced results only marginally
Horizontally I became VSWR between 1.1 and 1.0 depending on frequency !
