Very very unlikely!    The ISS is by far the strongest and most easily received 

The rubber duck is an absolutely HORRIBLE antenna  - the thing actually has 
NEGATIVE gain relative to even a simple dipole or quarter-wave whip.   It's 
more like a badly-shielded dummy load than an antenna.   You are reducing the 
already marginal transmit power output of the hand-held by at least 60%-70% 
compared to even a simple 19" quarter-wave whip

At the least, you want a full-size 19" whip, or far better, a light-weight 
hand-holdable 3 element Yagi like an Arrow antenna.
