I am no authority on different types of scatter but have observed from
my qth the following.
First the N0LL beacon is very reliable. I can tune to it's frequency
after failed WSJT attempts and hear the qrp tones hammering in. The
distance is about 730 miles. During most any day, it will cause single
tone decoding using wsjt thousands of time in a 24 hour period. Even
with it's many meteor pings and burns, it is not a good indicator of
conditions even running much more power than the beacon.
W5SNX is a distance of 814 miles from my qth. We are able to copy Dick
well most times even using JT44. It is not uncommon to have long
burns, several seconds in length on both N0LL and W5SNX.
Guess I need to do some more research on the different types of
scatter. I know to look for "BackScatter" during TE openings and have
experienced that often on six meters. Backscatter almost always has
some distortion and is limited to ranges around 400 -600 miles. I have
seen some posts that indicate they are working "Backscatter" because
the ping was received off the back of their beam.
Has anybody else experienced with any type of repetition scatter at
similar distances, that is very frequent bursts with large widths /
with often time long burns of several seconds.
I would be interested in doing more testing with stations at distances
around 700 - 900 miles. With the beacon it is simple to collect data.
Does anyone have any data relating to the differences between
troposcatter and D-layer scatter?
The attached file was this mornings typical burn from W5SNX while
working JT44. The burn appeared to be long enough to pick-up 5SNX
Tnx for the bandwidth...
