You can create a FREE Yahoo account and then join all the Yahoo groups that you like.
There are many that may help you greatly with SW monitoring.
I think you just go to groups.yahoo.com and there should be a link somewhere to create the free account.
Once you do that, then you can start joining the groups of which there are thousands.
Read the R75 wiki here at RR and I believe it will have direct links to the R75 yahoo group so you do not need to search for it.
Many of the Yahoo groups do require you to be approved first but that usually occurs quickly on most of them. Some may ask why you wish to become a member so just answer honestly and you should be approved.
Some of the groups offer instant approval as well.
Once you join and read the messages in a few groups, you will quickly learn which ones are good and which ones are bad. The bad ones will be filled with spam type messages and usually nothing recent related to the groups original intentions. When I join a bad one, I'll still look back through the oldest messages and files sections before I give up on that group as many did start out good but went to hell due too poor or no moderation.
Some groups are VERY active.
I like to set my personal settings so that the groups never email me with new messages as I like to just visit the actual group page when I'm ready to read the new posts. I sometimes go weeks before I have the time to visit all the groups I am a member. I think I belong to about 300 groups.
Yahoo groups is a valuable resource in my opinion.
I still come here several times a day but whenever I buy a new radio model, I always check and see of there is a Yahoo group specific to the radio model.
There are also groups specific to what you like too monitor.
Many people are into utility monitoring with a HF radio like the R75 so there are groups dedictated to utility monitoring. You mentioned military monitoring, I'm sure there are groups specific to that as well!
I bet Ridge will offer his advice if he knows of some yahoo groups that may interest or help you out.
Once you figure out and join one group, the rest are all alike so it will become very easy too join more groups in the future.
