KEY  To CARRIER  delay accommodation

where the  Linera  tx line / is  addressed   from the  secondary
contacts  on the Ae  relay , the  measured  Tx to  on-air carrier  delay 
is  52 mS , ptt  enable > Rf  wondering if this was too  long [ days  of amtor ]
Apparently  the  Vara HF modem can  accommodate  up  to

120 mS   delay 

may/may not affect  stations using  tx/rx sequencing

Somebody should invent something like SOUND HOUND, that listens on a smart phone and display the mode.   SOUND HOUND listens to music and tells you the title.

I use VARA CHAT...just a great program, any chances to have it work on 500, 2300 seems that is a long width...

Re: Winmor to be dropped from Winlink

James Clark
 

Indeed! Thank you Rick for your excellent efforts.

It was Winmor which allowed me to enter the Winlink arena and I was a user and tester from very early beta days.

I have no doubt Rick that had you costed your time developing Winmor it would have amounted to tens of thousands of dollars.

Thank you.

HI GUYS;
P2P is running great here, have made some connects thru Pennsylvania, ILL with strong signals. I have tested it with W0LEN also on 60 meters channel 3, wow what a signal during day light hours on 60 meters, s9 plus.
I belong to a group called winlink p2p, a number of stations on experimenting for propagation, message  handling etc. Contact w0len for info.
ANDY have my receiver set up on 10 to connect, when the band opens, which if lucky , it seems to open daily at some time.

I’ll take a look but at this point looking to test same VARA speeds used on the usual HF bands.

What's the   p97  say about data and  FM on  10  meters  ? 
used to be a  1200 packet  net on 29 something  using FM
many years  back, skip into  EU , vara FM would  fly on 10

Re: VARA P2P

Pat, I set up a P2P piece of mail for you . If others are interested I will be glad to set up P2P test messages for each station that puts VARA mode through its paces .  The challenge is ... I am parked on 10 meters . 10 meters because I would like to see what speeds VARA can reach when 10 is “open”.   A generally quiet band . I am on 28150 center frequency (28138.5 dial ) Hopefully I have picked a frequency that complies with band plan.
