Group Description

Welcome to the Spectrum Lab users group.

Spectrum Lab is a program for signal analysis. Initially it was just an 'audio spectrum analyser', focused on weak signal processing, but it grew a lot since then. Details about DL4YHF's Spectrum Lab are here:


This group started 2010-07 due to problems with the older 'Spectrum Lab' user's group, which still exists here, but new members couldn't seem to join it:


Please ask questions here, do *NOT* send private messages even if you think the question is too specific to be asked here. The SL author will stop answering SL-related questions in personal mails, since this consumes a lot of spare time
- time better spent for other things, like improving the software or the manual.

Like the older Spectrum Lab group, this group is moderated, not censored. It is moderated to prevent widespread spam. But, please keep off topic traffic to a minimum.

You will not be able to join without authentication. Most likely, you will be asked for your ham radio callsign. The purpose is to keep spammers out.

Good luck ! - Wolf, DL4YHF .
