Dear Roger,

thank you for this excellent summary and motivating words!

Regarding "best DX from a home QTH", we should mention Paul Nicholson'=
s amazing detections of my 5 uW EMRP transmissions in October at 1027=
 km: http://abelian.org/vlf/mv101009/ - something that I had not expec=
ted in my wildest dreams, until it actually happened.

Best 73,
Markus (DF6NM)

Dear All,

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

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

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

And what next on the band?

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

In all this has been a fantastic year. The thrill of seeing Stefan's=
 8.97kHz weak trace on my PC screen in December matched anything I had=
 done in amateur radio.  So, well done to all those who have put so mu=
ch effort into breaking down barriers in our hobby and opening up a fr=
esh place to explore.=20
A very special thank you to Stefan DK7FC.

May I end with links for:

- the sub-9kHz Yahoo Group open to anyone interested
- my sub-9kHz website where I try to make sub-9 news available to a wi=
der audience
