Re: VARA on computers with multiple network cards
If you¡¯re running a firewall (other than the native Windows Firewall), have you tried to temporarily disable it, see if that might be causing the issue? ?Some 3rd party firewalls try to restrict loopback traffic.
Also, can you give some specific examples of the virtual NICs you¡¯re having to disable? ?Some applications don¡¯t properly remove/disable their virtual NIC when not in use. ?That too could contribute to the problem. Last question, have you manually disabled IPv6 on some of the NICs? ?Having a mix of disabled/enabled IPv6 stacks can also lead to issuing processing loopback traffic. |

Re: VARA VU-meter
Take some screen shots and share.
On HF SSB I usually try for a VU meter around 12 O¡¯clock (-20dB) on a 1 kHz filter. If you use a wide filter (3 kHz) you will obviously get more overall noise. When receiving a VARA signal, the ¡°noise¡± seems less but of course it isn¡¯t, so the VU meter won¡¯t change a lot. Yes, the proof is in the S/N value, not the VU meter value. I think there is a wide range of RECEIVE audio that still works. I¡¯ve been told ¡°don¡¯t starve the sound card, but don¡¯t saturate it either¡±. The Goldilocks value is probably around 12 to 2 O¡¯clock on the VU meter. Try narrow filter if possible for VARA HF 500 Hz mode - see if the copy is better. But send some screen shots if possible de k3eui barry |

Re: VARA on computers with multiple network cards
I have a single NIC on my NUC (tehe) and netstat tells me that VARA is listening on 0.0.0.0 - not the 192.168.1.80 shown at the top of the dialog. You should be able to connect to it at any address present regardless of NIC. What does "netstat -ta" inform you?

Re: Need Help - US call sign - unable to send messages when traveling to Europe
¿ªÔÆÌåÓýHere is an excerpt from the Winlink Terms and Conditions on 3rd party traffic restrictions.?? Using ¡°Emergency¡± in the subject line in a non-emergency to circumvent US 3rd party restrictions law is a great way to get kicked off the system¡ ? Tom N5TW ? Third-Party Traffic For example: if a message originates from a non-amateur as an internet email in the U.K. and is delivered to a U.S. amateur over the radio from a gateway station in the US, no third-party rule is broken even though the U.K. does not allow third-party traffic over amateur channels. This is because third-party traffic is permitted between two US stations. Likewise, a message originating from a U.S. amateur and passed by radio to a U.S. gateway is okay even if it is addressed to the Internet address of a non-amateur in the U.K. Again, third-party traffic is permitted between the two US stations. The Winlink System servers automatically enforce US FCC rules regarding third-party traffic when at least one station in a circuit is licensed in the USA. US rules prohibit third party traffic between stations licensed in the US and a foreign country that does not have a third-party traffic agreement with the United States. A list of those that do is kept at:?. Should a message from or to an internet email address be proposed for transfer between stations where third party traffic is prohibited it will be held at the CMS for delivery by a pathway that will not violate the governing rules, and a service message will be delivered instead describing the situation and how the message may be legally retrieved. If a Winlink user tries to send third-party traffic through stations that do not permit such traffic, the message is refused and a service message will be delivered instead, describing the situation and how the message may be legally sent. These Winlink Terms and Conditions of Use are more conservative than the governing FCC rules in some situations. Users and sysops must make themselves familiar with third-party rules for the country in which they are operating as well as linking with if they are exchanging messages from or to internet addresses or non-amateurs. US gateway sysops should know that ¡ì97.219(c) provides protection for licensees operating as part of a message forwarding system. "...the control operators of forwarding stations that retransmit inadvertently communications that violate the rules in this Part are not accountable for the violative communications. They are, however, responsible for discontinuing such communications once they become aware of their presence." ? ? From: [email protected] <[email protected]> On Behalf Of Bryan Moris

I realize there is some type of law regarding passing digital data in EU if you are an US citizen.That is not the case, amateur radio is allowed under the CEPT arrangements.

Just access the Winlink system directly via the internet using your home call. If it¡¯s any consolation, we have a similar ¡°doesn¡¯t compute¡± issue with the D-Star network using our UK regional callsigns.

Re: Vara HF security encryption
Bundling a product that provides direct support for ham radio use with other components that are illegal to use in the US is a direct invitation for legal action against distributors by the FCC.? An example is what happened to US distributors of Baofeng/Anytone/etc products that could do both ham (ARS) radio and business (LMR) use.? After fines resulting from FCC legal action they were successful in getting the product OEMs to change the products they were selling to comply with federal law.? Individual holders of FCC issued ARS (ham) licenses practicing that also risk loss of their licenses. A modified VarAC product that eliminates ham band support may be okay to bundle with encryption for LMR or marine band use, but would also require compliance with other FCC regs for LMR which includes inability for the end user to change configuration or use frequency channels that are not assigned to the user org for their unique license by the FCC. Something to keep in mind for USA.? Stephen W9SK On June 10, 2023 10:57:42 AM "W8NSI James" <w8nsi@...> wrote:

Re: Vara HF security encryption
To Dave KO4KHB;
We understand your desire to package an encryption ham radio product with your commercial communication packages to government agencies for a profit. Ham radio by its nature is not secure. You can list URLs to download security software with your products or even burn a cd/dvd with them to include when you make a sale. Or you can contact the authors direct for a commercial encryption capable version. Or sell them a dragon P4 pactor modem! -- 73 de w8nsi Jim Yes, I am a VET too.

Re: Vara HF security encryption
I meant VARA moden not VaraC. Why add encryption complication to an amateur radio product when there are already easily publicly available methods of encryption?
