Dear All,

Less than a year ago someone called= 8-9kHz=20 "The Dreamers Band" assuming that results would be impossible, but= here we are=20 now with several stations able to do scientific observations of long= distance=20 propagation changes on the band! This is a band on which amateurs ar= e yet=20 again able to demonstrate real science in action and where the true= amateur=20 radio spirit is alive and well.

If I may summarise the 8-9kHz= band=20 status today:

- at least 6 stations active on TX= capable of=20 producing a far-field DX signal
- probably around 20-30 stations= able to=20 receive such far field transmissions
- around 10(?) grabbers moni= toring the=20 band either full or part time.
- best DX from a home QTH 699km- best DX=20 from a /P location 2873km
- others experimenting with earth mode= =20 propagation over local distances
- lots being learnt about antenn= as,=20 receivers and propagation (and pipes and wet fenland!).
- DX far-= field=20 transmission also successfully received on 6.47kHz and 5.17kHz.
And=20 what next on the band?

- some real 2-way QSOs (one was mad= e last year=20 in Germany over about 20km)?
- more home station far-field TX=20 operation?
- whistler mode guided DX into the southern hemisphere= ?
-=20 transatlantic reception?
- new coding techniques to allow QSO mod= e contacts=20 in shorter time periods?
