Re: Kenwood D7 and PSCAT2, ISS ?



Thanks to all who replied with additional checks !
It appeared that nothing was wrong in my set-up.

And therefore I gave it another try this afternoon:
- external antenna (2x10 elements)
- external power supply 12V: 5W HF power
First pass  (40 degrees), with ISS only partially over Europe:
successfull both over ISS as well as PCSAT2 !!
2nd pass (90 degress), with whole Eu in the footprint:
no success at all this time (hardly anyone b.t.w.).

Conclusion (for me): successfull contact with ISS using
QRP stations is in Europe mainly limited by the enormous
amount of enthousiastic stations, all trying to connect ...:-)

The PCSAT2 results & pic's are at: http://www.qsl.net/pa3guo, 
click on "ISS APRS" for the ISS results.
