Re: VARA FM settings for Icom ID-5100 #VARA

 

. On the IC-7100 for example, the internal sound card is limited to about 3kHz B/W, not near good enough for Vara FM Wide. I have tested this and it fails miserably,
A month ago, a user was claiming to have good luck receiving 9600 with
the internal interface of the IC-7100. While skeptical, I'm
encouraged to hear that report and look forward to testing it myself
RSN.

Perhaps VARA_FM could have a split mode functionality where it
received at 9600+/high-bandwidth but transmitted at a lower and
narrower speed.

however, using an external device like a DRA, and setting the external rate to "9600", it then performs fine on Vara FM Wide.
For HF digital, the internal card is fine, and it also works OK for Vara FM Narrow mode.

The ID-5100 is a V/UHF dual band FM/D-Star transceiver. It does not have an internal sound card. I'm not even convinced it has much, if any, CAT support. So really not sure why you would need this support from Vara FM.

Also, as to your comment about the internal sound card for other wide B/W modes, this is also not true. On the IC-7100 for example, the internal sound card is limited to about 3kHz B/W, not near good enough for Vara FM Wide. I have tested this and it fails miserably, however, using an external device like a DRA, and setting the external rate to "9600", it then performs fine on Vara FM Wide.

For HF digital, the internal card is fine, and it also works OK for Vara FM Narrow mode.

I assume  its the  same as the  IC7100  with  CAT 
if so , the  tx/rx audio is  also via the  USB cat port ?

The usb audio  is preferable to  external  sound card 
in any  case , especially  in the  wide  b/w modes

What sound card interface are you using that you need CAT PTT for the 5100? Just curious...

Not Just  17 meter , all the  bands have been  over run
as the  propagation returns , without a structured multiple 
access ,  its going to jam itself , which will  most probably
cause the  users to  move along the  dial  ..and so on

33 mins  later  -)

Will be added  to the next  version  of  VARA-4  FM, to  be  released in  7  days  


Work  around  , using the  existing CAT  listing   

Select IC-7100, for example, and enter  8C in the Icom  CV-I  Address

Two Autex WAV files and a small presentation #autex

Patrick Lindecker
 

Hello Al,

 

Hello a link about two Autex WAV files and a small presentation (below).

In this ZIP file, you have two AUTEX artificial records, supposed made from someone monitoring the meetings (SWL). Records  (made with 2 PCs) are not of very good quality, but sufficient to understand how it works:

·         One file (Autex2.WAV) in AUTEX 2 for a meeting between 2 Hams,

·         The other file (Autex4.WAV) in AUTEX 4 for a meeting between 4 Hams maximum, but here there are only 2 Hams participating to the meeting:

o   F6CTE as “Master” (let’s say the “Master of ceremonies”)  and

o   1ZZ9ABC/M supposed from Mars ☺, as “Guest”).

So 2 more Hams could enter in the meeting.

You can read these files directly, if you have a Multipsk user key. Otherwise, you can read these files with a standard Windows application and apply the generated sound to your sound card input, through a cable connecting the sound card output with the input.

 

Note the slow secondary channel which displays information about Hams (call sign + name, QTH or other).

 

Note that while monitoring, you could have to stand repetitions, for example in Autex2.WAV, where “Louise prefers a s” and “agent on the best way to go” are repetitions, this because AUTEX is an “ARQ” mode (i.e. with acknowledgment requests of transmitted messages).

 

Remember that the “Master” in Autex 4, 7 or 13:

·         must be a powerful station: the more participants, the more the HF power must be elevated,

·         must make run Multipsk in Autex on a fast PC.

For details, consult the manual (“Help” button)

Dans ce fichier ZIP, vous avez 2 enregistrements artificiels en AUTEX, supposés faits par une personne écoutant les réunions (SWL). Les enregistrements (faits avec 2 PC) ne sont pas de très bonne qualité, mais ils sont suffisants pour comprendre comment cela fonctionne:

·         un fichier (Autex2.WAV) en AUTEX 2 pour une réunion entre 2 OM,

·         l’autre fichier (Autex4.WAV) en AUTEX 4 pour une réunion entre 4 OM maximum, mais ici avec seulement 2 OM participant à la réunion:

o    F6CTE comme “Maître” (disons le “Maître de cérémonie”) et

o   1ZZ9ABC/M supposé de Mars ☺, en tant qu’”Invité”.

Donc 2 OM supplémentaires peuvent entrer dans la réunion.

Vous pouvez lire ces fichiers directement, si vous avez une clé utilisateur Multipsk. Sinon vous pouvez lire ces fichiers avec une application Windows standard et appliquez le son produit à l’entrée de votre carte son, à travers un câble connectant l’entrée et la sortie de la carte son.

 

Notez le canal secondaire lent qui affiche des informations à propos des OM (indicatif + nom,  QTH ou autre).

 

Notez qu’en écoute, vous pouvez avoir à supporter des répétitions, par exemple avec le fichier Autex2.WAV, où “Louise prefers a s” et “agent on the best way to go” sont des répétitions, ceci car l’AUTEX est un mode de type “ARQ” (c’est à dire avec des demandes d’acquittement des messages envoyés).

 

Rappelez-vous que le  “Maître” en Autex 4, 7 ou 13:

·         doit être une station puissante: plus il y a de participants et plus la puissance HF doit être élevée,

·         doit faire fonctionner Multipsk en Autex sur un PC rapide.

Pour les détails, consulter l’aide (bouton “Aide”).

What does the mode AUTEX sound like ? I haven't been able to find a sample sound of it on the Internet.

Oliver,

Have you gotten the ID- 5100 to work with VARA FM? I have tried everything but can't get it to work.

I am having trouble setting up VARA FM with my Icom Id-5100. The 5100 is not listed in the radio drop down box. Is there another option?

Andy,

Just saw your post. I have been calling CQ for 10 minutes (11/10/20) and have not seen a trace.

Have you had any success with your 10m activity?

Andy,

What results are you seeing with this daily 10m Activity Half-hour?

If it is promising, I will post it on the  PODXS 070 groups.io Reflector.

Thanks, 73,

VARA FM settings for Icom ID-5100

Tammy Waggoner
 

I have been trying to configure VARA FM to work with my Icim ID-5100 but the radio isn't listed in the drop down box. Can anyone help?


17M frequencies

Larry Mundinger
 

18100 KHz was once the place for modes like PSK but it was taken over by
FT8.  Since sunspots are coming back should we pick another frequency
and try to get some activity going? Would 18104 KHz work?

Contestia 16/250 now available with RSID in fldigi and MULTIPSK

Gerry Lawlor
 

Hi Folks
Having spent some time recently using Contestia 16/250 on 40m with others it's apparent that it's a good mode for marginal conditions and at an acceptable speed.  Comparison with other modes has been unfavourable during our tests around 2100Z between Europe and the near US.  Jim AJ8S has been using this mode successfully over a longer period on the path from Ohio to VK6 on 40m.  
Up until  now there was no ready method of setting this mode up other than by using the Config Modem menu in fldigi.  Also, no RSID was available for it.  However that has now changed.   Patrick F6CTE has incorporated Contestia 16/250 into the latest version of MULTIPSK and assigned an RSID to it.  Dave W1HKJ has now incorporated it into the latest version of fldigi -version 4.1.16.01. 
It would be nice to see others using this mode and availing of the superior S/N performance, which at -15 dB is 3 dB superior to e.g. Olivia 4-250 at -12 dB for the same ~20 WPM.   Generally, we play around 7068 kHz CF USB  at approximately 21Z.   Power levels of 200-300W to wire antennas have worked well.   A bandwidth of 300 Hz is very effective on RX. Of course,  there is no reason not to use the other conventional frequencies for digi modes now that an RSID has been assigned. 
Hoping to see some activity in this "new" mode.

VARA HF v4.0.6  PTT for RA Board interface

From Vara user group 

Addition added to the VARA modem  , supporting the  RA  interface board
notes, this board is  not  supported by winlink , hence the  direct address
option , 

[on air modem remains  unchanged]

That is interesting. I've wondered why the ISM targeted radios hadn't been used by us. There may even be some 9600 bps packet version that would work on 2m. Don't have the hardware skills to attempt a project so never looked that closely the radios. The NPR might also find us on the 33 cm band. Think I've seen ISMs in that band.
