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.

I think I will dial you guys in – here in northwest Louisiana . . . . who knows.  I might hear 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.

Andy , 

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.

I put the winlink in P2P, type a msg, connect with a station , but the message does not go out to the other station.
It works in all other modes pactor, ardop etc and sends messages, so must be doing something wrong but what NO idea.
Any suggestions?

Re: Whats new in VARA 4 ? #VARA #qrp

Trick's  of the  trade 

The low speed  ranges  of the  2.3KHz   wide  mode ,  are  designed  for a  filter
bandwidth  of ~ 1.5 KHz , higher levels requiring the  full  channel  

As  user  data and experiences  are gathered, one aspect  has become clear ,  the 
full  2.4 KHz voice  channel  is not  always  fully  available, hence to  ensure 
maximum efficiency , ie power transfer in the  lower  ranges , the  modem allows 
for constricted  channel  bandwidth,  either by  the  various  user interfaces  or 
filter bandwidth

Thus  ensuring the  bedrock  -20 dB  is achievable ,  independently  of 
equipment  irregularities ,  two  images  make the  point , using the
opera  waterfall  display , with  mouse  pointer/frequency  as measurement 
tool ,

First  ic7100  with  2.5 KHz usable  bandwidth  in data  mode 
using digital filtering . direct USB link to  pc 

The  second , FT897D offering a  much rounded response
with  app  1.5 KHz usable  bandwidth** using  usb 
soundblaster 24 bit  audio  card , fed  from  rig  data 
out 

** Why this is so,  may  be due to  filter  ageing ?

Interesting  comments  from  LA gateway   using the  500  mode 

Link maintaining   traffic   [ qso]   flow  down to   -20 dB s/n  
over quite difficult  high  latitude paths  , oddly , the  latest
simulator  tests , stop at -5 db s/n  ?

-20 .. Thats  a significantly  Low  signal level, well  inside
what  could be  classed as  weak signals  mode , for  comparison
the  op05 opera beacon  30 seconds ,  and  the  'qso mode 15 chrs plain text 
60 second tx time  line.  both  run to -20 dB possible  -23 dB 

As example ,  F5ZAL is a  2 meter  fixed beacon ,   running  10  watts  to  'halo'  type  ae  with  360 deg coverage , op05 / 30 second  mode,  being  spotted at  546 Km,  at levels that  would  support the  Vara  2300  and  500  modem

Easypal Ver07/Oct/2014 issue

Andrew Mummert
 

When we start up EasyPai, there is a light grey flow on the waterfall.

No activity in the wave bar. No IO, No RX.

This is happening even without the radio attached.

Has anyone come across this issue?
