Thanks David, I listened at 5:30AM this morning to your presentation.
Well done. The ionosphere can give a HF transmitter massive coverage far exceeding the coverage of any VHF/UHF terrestrial repeater. But, this does not help with medium distance two-way communications. OH YES IT DOES, place a REPEATER at the above transmitter site. With "digital voice" two problems for a repeater are solved: 1) Is the signal valid? . . . . . . . . . . Presence of specific sync. 2) Does the signal want to be repeated? . . Embedded data with the voice. I see this as so so important, visionary. --------------------------------------------------- Alan VK2ZIW OpenWebMail 2.53, nothing in the cloud. _______________________________________________ Freetel-codec2 mailing list Freetel-codec2@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freetel-codec2
