WSJT-X Software
K1JT, Joe’s WSJT software made EME possible for average terrestrial stations. The new WSJT-X added additional features like Doppler-Compensation and new modes like QRA64 (used manly on 6 and 3cm EME). You may download it for free at: http://physics.princeton.edu/pulsar/K1JT/. We have used it with great results from 50 MHz to 10 GHz EME. On Joe’s home-page you also find all needed information how to operate WSJT and EME.

This e-mail-reflector is a great please to share information about EME and of course to ask for help, announce activity and arrange skeds: http://www.nlsa.com/nets/moon-net-help.html

This are chat-rooms where EME operators meet to share online-information about their activity. It is a great place to get the feel for the activity on EME. You easily find almost any time a sked-partner for a test or you see where to listen for signals!
You find the loggers at:
for 50 MHz at: http://www.on4kst.info/chat/login.php?band=5
for 144 MHz at: https://www.chris.org/cgi-bin/jt65emeA
for 432, 1296, 23xx, 3400, 5760 and 10xxx MHz at:

Please NEVER post data of ANY ongoing QSO on the logger. It is okay to exchange details of the test after a QSO is finished or after a sked failed. It is very important that you help to make sure there are NO QSO’s made thanks to information obtained via the logger and not off the moon! Many thanks!

Interested to try?
Last but not least, we would like to remind you, that we would love to work you off the moon! Please let us know when you are ready to try or when you need a signal of the moon to test your equipment. If there is anything we can do to help you become QRV, let us know, we’re happy to assist you!

Just contact me at dan@hb9q.ch
I hope to read soon from you or even better to work you on random off the moon!


Minimum requirement to work HB9Q on EME

With the introduction of WSJT (many thanks Joe, K1JT!!!) a new world was open-up for many VHF, UHF and SHF weak signal operators. It is now possible to work VHF and UHF EME on a regular base using just 1 yagi (even a small one) and 100 W (or even less!!!). With such equipment it is not only possible to work the few very big guns, NO, it definitely is possible to work several if not many stations. And on the microwave bands it is enough to have an avarage Tropo station to work the big guns and even the bigger mid-size stations.

To work HB9Q you only need on

  • 144 MHz: 1 yagi and 50 W 
  • 432 MHz: 1 yagi and 25 W 
  • 1296 MHz: 1 yagi and 10 W or a 1.5m dish and 5 W
  • 23xx MHz: 1 yagi and 20 W or a 1.5m dish and 10 W
  • 3400 MHz: 1.5m dish and 20 W
  • 5760 MHz: 1.5m dish and 10 W
  • 10xxx MHz: 0.6m dish and 10 W

It would be great if YOU would join the EME-family, adding yet an other exciting station to be worked!
