VARA on FM?

 

Is there a way to use VARA on FM, hopefully on surplus land-mobile vhf FM transceivers, to achieve better than 2400baud?? Or maybe better noisy-link performance than Bell 202 or whatever the MFJ-2400 modem is???

Second link down! :)
 

Thanks!?? Does this require a MSWindows machine??? Or can it run on some embedded platform??? I suspect it could run on an Intel NUC.? But is it supported on Raspberry PI?

Can a single computer support simultaneous transactions on 2 or more transceivers?

What kind of bytes per second could one expect using Winlink over FM with VARA FM??? What software must the fixed-station computer be running?? Does this work with G8BPQ's RMS server??

Thanks again.

It looks like the VARA FM will work at 9600 but only on designed-for-9600 radios??? The reason I bring this up is that one of the things I think VARA does well is compensate for what happens between the VARA modems.? I would expect it to do better than many of the old-school FM packet modems on a not-made-for-9600 radio.?

I wonder if anybody has ever tried this.???

Windows...
I have 2 instances of VARA Hf
2 Instances of ARDOP
2 Instances of WINMOR on a Windows 7 Laptop controlling two HF rigs via 2 Signalinks.

All controlled by my Linbpq PC thru the Ethernet link..

I think the only way to use a Pi running say PiLINBPQ would be with a networked windows PC running VARA FM.. But You may ask the Author???

I have not tried VARA-FM yet... I may give it a shot...

Oh Yes it works with G8BPQ and its RMS system.

Windows¡­ ?ONLY¡­

No RPi¡­

I have a dell Laptop 3 GHz CPU 500 GB SSD

8GB ram

Runs two instances of VARA for HF, 2 Instances of WINMOR and 2 Instances of ARDOP.. With only 10-20% CPU ¡­

I run mine under BPQ.. (Specifically LinBPQ linked remotely to the WINDOWS PC.. ) I have one instance of VARA FM¡­ on same laptop¡­

I use a Icom 706 for one instance of each and a 746 for 1 instance of each on a 746
