SHORTWAVE: What's out there nowadays?

Way back I occasionally tuned my receiver outside the ham bands and scanned
the shortwave broadcast bands. They were a perpetual cacophony of AM
stations
transmitting propaganda, lots of it seeming to come from Asia,
radioteletype, strange continuous signals that sounded like motorised
woodsaws (common opinion was that they were jammers, I never got an
official explanation), a small amount of sideband transmission, and in
latter years the 'woodpeckers' or OTH radars. What's the situation nowadays
relative to then? How has the usage of and demand for HF changed? What's the
future for it look like? Any officionados out there care to comment?

You might be better off asking this on:
aus.radio.amateur.misc

well what would you expect different ?

Shortwave jammers and pirates

The 20-metre amateur band is now home to megawatt shortwave jamming
transmissions, or their parasitic signals, and an increasing number of Asian
pirates.
On any night 5 by 9 plus jammers can be heard on several 14MHz band
channels. Also to be heard are unidentified CB-like telephony transmissions
in Asian languages. They are easy to pick being mostly on Lower Sideband in
the CW segment of 20 metres. If you care about the future of our exclusive
HF bands, do something about it.

Send your logged observations to the VK3 Intruder Watch coordinator, Jimmy
Hall VK3TZE, intruders@wiavic.org.au.

Also on the website or available from Jimmy VK3TZE on request is a list of
common intruders being regularly heard in IARU Region III.

A latvian talks about there existing a radio tower which was functioning as
a jammer.
Since he lives/lived there, we might trust he got the truth on the matter.
