Re: Vara HF security encryption
Hi Roy,
Thanks for info,
Looks like this topic got a bit of interest and we now have encryption option in VARA which is great.
All the best from NZ

Paul;
Have you entered your call sign in the "Winlink Express Setup..." window? A Winlink RMS Gateway station won't respond to a connection request if you haven't set up your call sign in Winlink Express.
Are you selecting the Winlink RMS Gateway station you're trying to connect to from the 'Channel Selection" menu on the Winlink "Vara FM Winlink Session" window?
Using VARA FM, you can do some diagnostics with either the 'Ping' tool that's available?on the menu bar on the VARA FM modem screen, or with the "Auto Tune" tool that's displayed?when you select "Settings -> SoundCard..." on the VARA FM menu bar, and then click the red "Auto-Tune" button on the right side of the "SoundCard" window.
On either the "Ping" or "Auto-Tune" tool, you must enter the call sign of the station you're connecting to (shown on the "Connection" field on the??"Vara FM Winlink Session" window) into the corresponding "Ping to:" or "Calibrate with:" field, and then click the button with the power-plug icon.?
When you run the "Auto-Tune" tool, VARA FM will transmit a sequence of 10 short bursts of digital data, at an increasing audio level for each step. If your transmit audio level is set properly, you'll hear all 10 bursts, at steadily increasing loudness, on your monitoring receiver. When your transmit audio level is set properly, a nearby VARA FM RMS Gateway should send a short digital data?burst, in response to either a "Ping" or an "Auto-Tune", that you'll hear in your receiver.
If you're not hearing the response burst from the Winlink RMS Gateway station, it may be that the station can't "hear" your signal, or the Gateway station is "down" for some reason, or you don't have the call-sign of the Gateway station entered properly in the corresponding "Ping to:" or "Calibrate with:" field.

Great idea, I will drive to the antenna and give it a try. Thanks.
Hi Paul,?
if you're able to hear the baofeng transmit from another radio, it sounds to me like the digirig/winlink system is working. I've found that even with my 50watt radio some packet and vara fm sites just can't "hear" me... So maybe you're having something similar happen to you. Can you try, assuming you are close to the vara site, get closer and test your system?

I have my digirig configured to my laptop which is running Winlink express. The digirig is connected to my Bofang. I am allure able to send code to my bofang and it is keying through ptt, the red light comes on.? I also have my main radio set to the fm frequency and I can hear the tone on it from the bofang. The problem is I am unable to connect to the repeater .?

Re: Vara HF security encryption
Hi Nigel,
The comm. units for govt. have access to a variety of secure comm applications...text, files etc. usually- supplied by the vendor.? Our micom's had built in encryption for text and email for example, and our CAD covers everything on our vhf/uhf systems.? ?Ham apps are not designed to be secure...and can't be (in the U.S.). -
There are obviously different levels of security necessary depending on scenarios.? You can minimize exposure by keeping comms at minimum power, point to point directional antennas, and brief.? A state sponsored adversary will go to greater lengths to identify info.? Media and most criminal enterprises won't have the capability to snoop winlink comms...especially if they're point to point.
We've sent files on request that were internally password protected (MS Word /Excel).? Not strictly legal over ham frequencies in U.S., but ok on LMR frequencies.
Good luck.? I'm sure you'll find appropriate solutons.

Re: VARA HF v4.7.7 has AES 256 encryption option for NON HAM users ONLY
Hmmm. What about BPQ32? Not everyone uses Winlink Express, RMS Relay, RMS Trimode, etc.

The main difference between V-FM and V-HF is that? V-FM? has no AFC ,? being designed to run over FM systems, The modulation system has no affect on the? recovered audio? spectrum , ie its not shifted? +/-? from net or subject to phase or other HF path disturbances, so less over heads = more room for the payload?
Its quite possible to? run V-HF over any link available?

Mark,
Thank you and I knew I was missing something to take advantage of. ?After working as an engineer in the communications industry ie cable I knew Quadautre would get more data down a path. ?But limited bandwidth can limit the data rate. ?

Tim;
VARA HF is designed to take maximum advantage of SSB-modulated signals with an audio bandwidth no greater than 3KHz, and to deal effectively with the highly variable signal "impairments" (fading, electrical noise, QRM, etc.) that occur on HF radio paths. The WIDE configuration of VARA FM is designed to take advantage of a 6KHz audio bandwidth, as allowed (in most regions) on VHF / UHF bands.
While the NARROW configuration of VARA FM operates in a 3KHz audio bandwidth, either VARA FM configuration (WIDE or NARROW) is designed to work optimally over FM radio circuits, with far less challenging impairments than encountered with amplitude-modulated signals on HF bands.?
You'll also find that the SSB modulation systems on 'all-band' (HF /6M / 2M / 70cm), and VHF/UHF 'all-mode' radios, is limited to a 3KHz audio bandwidth... regardless of whether you're operating on VHF / UHF bands.
Consequently, when operating on VHF / UHF bands, VARA FM WIDE or VARA FM NARROW (on FM radio circuits) is always going to offer substantially higher throughput than VARA HF (on SSB radio circuits) .

Has anyone run VARA HF on UHF with a radio that can run sideband. ?I would think you could get more speed with quadature modulation vs FM. ?If no one has done a test I will have to try with my 991A. ?

Re: Vara HF security encryption
Hi,
This is not the case
We are just planning options for supply ecomm with council and police and in planning stage. This is not for any profit and will be done as a under existing AREC group. This is not supplying police or anybody for commercial infrastructure. It¡¯s to provide coms in an emergency when everything else fails only
Still in planning stages currently
Thanks regards Nigel ZL2SEA

A few ways to fix this but an update isn't necessarily one of them. If you're in Linux (which I doubt since you refer to them as 'com ports') there is a way to fix it but in windoze.. the easiest way is to go to Device Manager and reassign an unused port to a lower number.? There are videos on YouTube on how to do this or we can do a quick zoom session and I can share my screen and show you. mwcarpe AT yahoo DOT com if you want to discuss further.

I posted this same basic question in a different io group space, before knowing of this space.
In my set up I have configured many comports, currently I have 4 pcie hardware comports, 2 motherboard supplied and 1 usb supplied, as well as a number of virtual comm and PTT ports up to number 26.? I am new to the VARA FM and have found it does not support comports above number 16.? Is there a way for in a future update to enlarge the accessible numbered comports to be above 16??

Re: Vara HF security encryption
If you intend to send encrypted messages to DoD or Govt entities they all use offline encryption and if you are one of those authorized to communicate with those entities you would also have access to their offline encryption sources.
Just my 2 cents.?
