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

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?

vARIM Messaging Program for VARA HF Modem - version 1.2

Bob NW8L
 

Hello,
 
Introducing version 1.2 of vARIM, a host program for message passing and file transfer using the VARA HF modem. Download links are here:
 
 
on the vARIM Documentation page.
 
Files are also available in the Files area at the arim-ham Groups.io group:
 
 
This is a maintenance release. Changes include:
 
v1.2  12Jul2020
---------------
1. Refresh Top Status Bar when port name is changed with the
   'pname' command.
2. During an ARQ session, update timestamp in Heard List whenever
   data is received from the remote station.
3. Immediately detach from the VARA modem on detecting that it has
   closed the TCP connections (e.g. VARA shut down by operator)
   and reset application state.
 
vARIM is a peer-to-peer messaging and file transfer for HF bands. It will run on Linux, Raspberry Pi, Cygwin/X on Windows and Windows Subsystem for Linux (WSL) on Windows 10. The VARA modem runs only on Windows computers, but vARIM can run in Cygwin/X or WSL on the Windows computer, which is convenient. Alternatively, you can run vARIM on a Linux or RPi computer and attach it to a VARA modem instance running on a Windows computer in the same local area network.
 
For Linux OS, the binary distributions are for Ubuntu 18.04 and derivatives like Linux Mint 19.x only. It's best to compile vARIM from source code to avoid library versioning problems. It's easy, instructions are found in the INSTALL file included in the source distribution (with instructions for Fedora 28 and derivatives, and for Cygwin/X too).
 
vARIM works with VARA HF version 4.0.x which introduces a robust 500Hz ARQ bandwidth option. vARIM allows you to specify which bandwidth to use in the .ini file, or as a choice in the "ARQ Connect" dialog (500 or 2300 Hz).
 
To key the rig, if VOX isn't suitable, vARIM supports hardware PTT using serial port RTS or DTR signals. This works on Linux, RPi, Cygwin/X and WSL using built in serial ports or USB-to-Serial converter cables. PTT setup details are found in the Help page. 
 
I have a station running VARA HF version 4.0.3 on (dial) 7.085 MHz that's available for testing. The station call sign is NW8L and it will be configured for ARQ using the 500Hz bandwidth. It might be QRT from time to time if thunderstorms are in the area (near Albuquerque, NM). At NW8L vARIM is running in WSL on the same Windows 10 laptop that hosts the VARA HF modem. The audio interface is a USB sound card connected to line in and line out jacks on the rig. The rig is keyed using vARIM's hardware PTT (DTS) over a USB-to-Serial converter cable between computer and rig.
 
If anyone using VARA HF has time to test vARIM I would be interested in your results and bug reports. If you install vARIM, try connecting to NW8L on (dial) 7.085MHz and sending me a message!
 
73,
Bob NW8L

if you are using paired virtual ports , try removing the paired ports and then re-create the pair

Many of us in this group enjoyed early experimentation with Rick’s Winmor and reliable use of this mode on Winlink and P2P .  Thanks to Rick for this and for his work with the current ARDOP.

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

Tomasz
 

Hello.

I have a problem with Vara HF V4.03 settings with Winlink Express. With the previous version and my settings, everything works. Now winlink does not control the PTT of the Vara modem. Vara Terminal with the same PTT settings works with Vara HF V 4.03 without any problem. RMS works and controls PTT in other ardop winmor modes etc. What could be the problem?

All the Best, 73

New release of MULTIPSK (4.43.1) #Multipsk

Patrick Lindecker
 

New release of MULTIPSK (4.43.1)

 

Pour les francophones: la version en français de ce message se trouve sur mon site (http://f6cte.free.fr). Il suffit de cliquer sur le lien "Principales modifications (courriel avertissant de la sortie de la nouvelle version)".


Hello to all Ham and SWL,

 

The new release of MultiPSK (4.43.1) is on my Web site (http://f6cte.free.fr/index_anglais.htm).
The mirror site is Earl's, N8KBR: https://www.paazig.net/f6cte/MULTIPSK_setup.exe

The MD5 signature of the downloaded MULTIPSK_setup.exe file to, possibly, check (with WinMD5 for example), that the downloading works without error, is equal to:

d24088f4a08b45e3f55075191d008734

Multipsk associated to Clock are freeware programs but with functions submitted to a licence (by user key).

 

The main improvements of MULTIPSK 4.43.1 are the following:

 

·                     Addition of the Contestia 16-250 sub-mode + its RS ID (number 275).
This sub-mode can be used under a noisy channel (minimum signal to noise ratio of -15 dB) with a reasonable characters transmission speed, of about 20 wpm.

·                     Decoding improvement of ACARS, SYNOP, EGC and VDL2 modes.

·                     Addition of two prediction functions in the "Satellites" window:
- over time "Advance" function, to see the satellites trajectories in the future, up to 4 h,
- minimum distance in km/miles + azimuth and elevation at the shortest distance between the satellite and the user.

 

Other improvements:

 

·                     "Knots" unit added for HFDL, ACARS, VDL2, AERO, ADSB modes.

·                     Integration of the rsp_tcp.exe V.1.1 file for the Multipsk interface with the SDRplay RSPdx receiver. However, the SDRuno version 1.4 program must be installed. For more information, see: https://wiki.radioreference.com/index.php/Connect_the_SDRPlay_RSPs_via_TCP_IP_to_Multipsk

 

Note about translation of Multipsk.exe and Clock .exe:  the 4.43 version of Multipsk has been translated to Spanish by Joachin (EA4ZB), from French.

See: http://f6cte.free.fr/Translation_files.htm.
