Ok John,
Fine on that, well have a look back in you files , about 9 till midnigh
i saved one file at 21:12 , shows a qsy , hf which resulted in the carriers
dropping out ..
the bham plots also show the strenght changing with frequency, but still
inside the 'normal' qsb time of 60/90 seconds . Stopped the test after
about 1 hour and set the cw beacon running.
Next time , ill see if i can get a signal top/middle and bottom band .. see
if changes the pattern ?
Tnx
G ..

Hi Graham,LF
My mistake! It was IO83LK... That'll teach me for trying to read CW
visually and then remembering it in order to write an email.
Had a short run tonight looking at selective fading , using your band
display ,Ran 3 carriers spaced 100 hz appart , just looking at the
amplitude change at your end .. , some intresting captures , looks
like the frequency has something to do with the path, not so marked
at birmingham .. id noted something a while ago, when running two
data streams , testing with gary, the higher frequency one did not
show on your site, till some time after the lower one .. odd
I will have a look through the captures and see if I can spot the
effects you mention. If you need any pics I can send them down. Each 5
minute capture is stored here.
Wonder if the auroral conditions played any part in the propagation?
Regards,
John
