Dear Roger,
 
thank you for this excellent summary= and motivating=20 words!

Regarding "best DX from a home QTH", we should mention= Paul=20 Nicholson's amazing detections of my 5 uW EMRP transmissions in Octobe= r at 1027=20 km: http://abelian.org/vlf/mv101009/ -=20 something that I had not expected in my wildest dreams, until it actua= lly=20 happened.

Dear All,

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

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

- at least 6 stations active on TX capable of producing= a=20 far-field DX signal
- probably around 20-30 stations able to receiv= e such far=20 field transmissions
- around 10(?) grabbers monitoring the band eit= her full=20 or part time.
- best DX from a home QTH 699km
- best DX from a= /P location=20 2873km
- others experimenting with earth mode propagation over loca= l=20 distances
- lots being learnt about antennas, receivers and propaga= tion (and=20 pipes and wet fenland!).
- DX far-field transmission also successfu= lly=20 received on 6.47kHz and 5.17kHz.

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

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