This video goes into way more detail than the earlier Digital Modes video. Yes, it’s 45 minutes long, so set aside some time to really absorb the information in this video introduction. After you view the video, study of the ARRL General Class License Manual should be a breeze.
The link referred to in the video takes you to a video I made earlier that shows a complete PSK-31 QSO using Ham Radio Deluxe / DM-780. When you have finished watching these videos, you can return to the main video list by clicking here.
Unfortunately I can’t edit videos once they’re up.
Dave.
Thank you for all the information about digital modes.
I did have a bit of problems finding it in my general class manual until I found that my Manual was the Eighth Edition good until June 30, 2019.
You may make notes at the start prior to the video for everyone to check there Manual for the section you are talking about prior to watching the video.
There are two forms of packet communications: linked and unlinked. A linked conversation is just between two stations. The unlinked, often called unproto (for “without protocol”) is a message sent out without a specific destination address. The unproto method has to be used when transmitting to more than one station at a time, say, for example, during a net operation. To call CQ, you use the unproto method, and simply put “CQ” in the unproto message. Normally packet receiving while not linked to another station will provide a readout of all the unproto messages being sent, so it will pop up with the CQ. It’s actually simpler than it sounds, but some perusal of the user’s manual that came with your TNC or software will provide more information. 73, Dave
So how does one call CQ with Packet? Is that even possible without an addressee? Perhaps everyone listens for the address “CQ.”
Yeah, I understand PSK now. ty
