Good morning,
 
As some of you know, i have been working in a new VARA HF since months ago. The objective was improve all the lines of the code and, specially, increase the sensitivity with low S/N, getting good performance with bad and good conditions.
 
The result is the new VARA HF v3.0.2 and can be downloaded in the official VARA site without extra cost for VARA licenses:  https://rosmodem.wordpress.com/
 
Sysops have been notified by the WDT and will try replace VARA v2.2.1 by the v3.0.2 on July 27th (or even before) . 
 
The default retries in this new VARA is 10 (instead of 5) as now the connection protocol is faster. Set the number of retries that best fits with your usual Gateways. The time between retries is 3.2 seconds, so 10 retries are 32 seconds cycle. And DWELL time (for Gateway sysops) is 4 seconds.
 
special thanks to Martin HB9AUR for the countless hour spent testing VARA prototypes
