FIRST QSO ON
500KHz USING ROS 30 April
First qso on 500 KHz using ros ,
G0NBD and G4WGT , initially
using 500/16 and then eme ,
reducing tx power , the level that
the eme mode started to fail was in
technical terms ?just silly?
reducing the tx to 3
watts carrier power then via a 20 dB attenuator down to 30
mW to a 35 ft top loaded Ae
that needs round 50/75 watts to
produce 100 mW erp , ie
approx 500 : 1 reduction ??.. reception 30 miles away by a similar Ae , then produced 100 % copy , depending on local noise level ?
Later in
the evening , M0BMU called
G0NBD at 500/8 , a range of 200 miles , then follower at 100% qso over some 30
mins ending round 0010 local time , one final tx at 500/16 was also 100% decode , even in deep QSO , to the point of no audio from the speaker, the
mode remained in lock and kept printing , each station running 100 watts.
Outstanding mode Jose !
