Thanks Graham, I have downloaded and it installed without issues. Seems my registration from previous versions has been accepted. I'm not actually sure how to use since almost all my previous use was with RMS Express. I am not sure if there is again a stand alone use, will poke around some more.

I think you may find , the new 'Chat' application , quite novel, in that it gives access to the modem at all speeds , but , I for one cannot type that fast ! , running the 'chat app , calls the vara modem ,
Chat provides the Rig control , via CAT or Com-ptt and the modem , the audio interface and tune button , now a single 1500 Hz test tone .The new modem has improved low signal performance , this with the arq function , makes for low power error free qso's , at power levels much reduced from the days of amtor
Though not intended , the unlicensed [free for all] modem runs to 175 baud level 3 , min being 40 baud , ample for qso , but notably , for the qrp users , the modem remains MFSK as is the ACK frame , being phase continuous , allows it to be passed via non linear systems , ie , class E/D power stages , which will be of interest to the low power / battery emergency situations ,
Entering a valid key , enables the faster levels, which are ofdm and require linear handling.
Might be of wider interest to list possible watering holes for 'vara chat' ? first over the pond might be a start !
