Speak Freely looks like a very good VoIP program for HSMM. IRLP uses a Voice-Over-IP (VoIP) streaming software called Speak Freely. VoIP is the technology that allows you to send your voice over the Internet. Speak Freely is Open Source under the GNU General Public License. There are two versions of this program Release 7.2 for Windows with Crypto. This is the version that you could have encrypted or private conversations. As Hams, we would need to use the Non-Cryptographic version which has all encryption capability removed. In initial testing this program works very good. It is easy to use and will act just like a push-to-talk radio. This will make it very familiar to Hams.
