Hi Steve;
I'm a Zero Retries subscriber... keep up the good work! ?
I apparently overlooked the "Mercury software-defined modem" item.
I checked out the git-hub site, and looked for other references on the 'net. Very interesting, and somewhat promising.
I can see where (with a considerable amount of further development) the Mercury software designed modem might result in a low-cost "VHF/UHF FM radio-modem "appliance" that could compete with VARA FM. However, I believe there needs to be a good deal more "machinery" to make it an effective HF modem.
In either case, though, it's very unlikely that either a 'VHF/UHF FM' version or 'HF' version would be compatible with the corresponding VARA system.
