Mailing lists

It is strongly recommended that everyone using GNU Radio and/or the USRP subscribe to the discuss-gnuradio mailing list. It is the proper place to ask if you have any questions or problems. For specific questions that require a single answer and no discussion, Stack Overflow is also OK for asking questions (tag your question 'gnuradio').


Due to recent problems with bad actors on the mailing list, all new subscriptions are under moderation. Subscription requests will be handled as soon as possible and generally well within a day. Thanks for understanding.

Guidelines for posting
