altitude of Kaboul in Afghanistan question.

Tanks for the Info !

I'll concentrate on 80 meters on nights and on 40 meters during the
day. The gps gives me 1793 meters above sea level. It's more quiet
in reference to noise compared to Quebec-city with all our nice
hydro-electric heavy power lines ... hi

Take care

I hope you made it ok to Kabul and back home in one piece. NVIS should work better than vhf in the hills, and like you concluded your altitude even if in an aircraft is so much less than the height of the E or F1,2 layers it makes no difference. But I would expect that the dry rocky ground conditions would require a different antenna strategy to obtain vertical radiation from the ground compared to radiation reflections from more conductive grassy soils of North America. What type antenna did you use?

What kind of modulation were you using? If data, what mode and how fast of a data rate were you able to use? NVIS should be much more stable than a DX ionospheric wave and support a wider bandwidth.

Yes everything went well Paul.(':)') We went from Kabul to Bagram several times to validate the HF bridge in the summer 2004.

Simply put, we were using basic voice in upper side-band.
(Have to be careful here ... the intelligence guys are watching over my keyboard ! hi hi )

Went there from 23 January 2004 to 8 July 2004
Had lots of fun. Met a great guy from the Signal US forces. We were together for one week.

Moved to a new base from Quebec to near Montreal in 2006.
Still having great learning going on for the ionosphere since the last 26 years, from age 11 in 1981.

May go back to Afghanistan ... depends on Wife ... hi hi
