G'day,



I want to try FreeDV on VHF SSB. It seems that there may be a VHF SSB
version of the SM1000 in the pipeline or already available. Is either so?
I.f so does the VHF version have a different designator? Where can I get
one in Australia?



Thanks in anticipation of any info relating to this matter.

Hi Gordon,

The only SSB version available is the FreeDV application and the SM-1000.
Though intended for HF, they work on SSB at any frequency. The VHF work
currently in development is for some form of FSK, which will work with the
non-linear amplifiers we generally use in handhelds.

Thanks

Bruce

Right thanks Bruce,



That would seem obvious but some implied info prompted the question --- will definitely give it a bash on VHF --- and HF too for that matter.



73,

Gordon VK3EJ.

Hello Gordon,

The current FreeDV 1600 mode works just fine on VHF SSB - in fact I feel
it sounds better than SSB. You can use a SM1000 or the FreeDV GUI program.

We are also developing some other FreeDV modes especially for VHF/UHF.
More on that later.

Cheers,

David

Thank you David,

Will order an SM1000 in an hour or so after walking the dog --- a morning
must. What it sounds like in relation to SSB is not relevant to my thing
which is whether or not it enables contact with stations at a lower level
---- which is a big maybe but will give it a bash.

Thanks again,

Gordon VK3EJ.
