For over 30 years (!) this Hellschreiber Net has been taking place every Sunday:

Frequency: around 3579 kHz

Mode: Feld-Hell (of course!)

Time: depending on seasonal propagation conditions:

	Currently: 16:30 local time in Western Europe (15:30 UTC).
	The net may be skipped some weekends in July/August, due to vacation of the primary operators (PAØAOB, PAØKDF, PA3FFZ)

Stations primarily from The Netherlands, some with original Feldfernschreibers; everyone is welcome!

On 6 December 2009, I finally managed to participate in the Net, from my QTH in the south of France. My brief QSO with Bastiaan, PA3FFZ was my "first" Hell QSO on 80 mtrs and covered a respectable distance of 1084 km. I used 80 watt and my ZS6BKW-dipole (reduced to 2x 13 m and installed as "inverted-L").

If you're beyond range on 80 meters, you can listen live via this great web-sdr located at the Technische Universiteit Twente, in The Netherlands. This is what I do myself, and when I'm SWL-ing, you can follow the QSO on my Hell-WebCam.

In the early years, when there were still plenty of sunspots and 80 meters was pretty much "dead" for shorter distances, the net took place on 40 meters. At the current (extended) bottom of the sunspot cycle, it is the reverse.

40 meter band: 7050 kHz, USB
