Hi again Geri

 

I remember the SM stns using normal SSB on a beacon QRG 505 +/-. a couple of years ago but not compressed.

 

I was thinking that there must be a method or algorithm that has a look up table of "diphones" and is able to utilise the repetitive sounds, spaces and diphones of the language in use (hard luck German has over 2500 Spanish has 800). Thus a real time narrow band communication channel carrying only pointing data would result. The outcome will probably be a cross between Donald Duck and Stephen Hawking in a channel of a few Hz? Any mileage (sorry Kilometreage) in the idea?

Just thought to make the sound like the sender there could be a real time slowed down session of key words to build the diphone library prior to the contact so the following QSO would sound nearly normal. This library would build over time so the system training would only need one session for a particular stn then on future QSOs a call sign entry would only be needed...... better stop now I am scaring myself. Maybe get it all on one PIC...... not?

Markus and I once had a successful "Slow SSB" QSO on 137 kHz years ago in our German 800 Hz bandwidth limitation. We slowed down normal voice four times, transmitted it over SSB and expanded it again by reversing the process ... using the full 7 kHz would make a fine AM signal, indeed ... perhaps even a low deviation FM signal would do?

Be creative, by 73

Roger, yes, a couple of us are thinking about some QRP AM across town (subject to non QRM to other locals), and why not?

Some sort of agreed band plan would be helpful ASAP as well.

My two NoVs were dated 20th. December, but it does say 'Date of Issue', which isn't the same as 'Date of Commencement', 'With Effect From' or whatever. It was clear from the Ofcom site where the link was that the NoV comes into effect on 1st. January.
