| Change ARRL email forwarding address? | KG6POV | 5 days, 14 hours ago |
| http://www.arrl.org/member-support This page has detailed information on testing the email forwarding. It suggests waiting six hours for the forwarding to update. To Test Your @arrl.net Alias *Please allow approximately 6 hours for the e-mail forwarding service to activate after you have selected or modified the information* Please send a test e-mail from an account other than the address in the "E-mail" field in your profile. Test messages cannot be sent to yourself. For Example, your e-mail address is jsmith@comcast.net and your arrl.net alias is xxxxx@arrl.net. If you send a message from jsmith@comcast.net to your xxxxx@arrl.net alias the message will not forward back into your jsmith@comcast.net inbox. Send a test message from an alternate account to get a reliable test and avoid a bounced message. Note: You cannot have your e-mail set to forward to your xxxx@arrl.net alias. This action causes a mail routing loop and mail will fail to be delivered. Also, a bounced message usually does not get generated in this situation. For Example, your e-mail address is jsmith@comcast.net and your arrl.net alias is xxxxx@arrl.net. You cannot have jsmith@comcast.net forwarding to your xxxxx@arrl.net alias. Note: A common bounce message that is received through the arrl.net forwarding is the "User unknown" bounce. This may mean that you are not opted-in for the forwarding service or you are not a current active member of ARRL. Please make sure you are opted-in to use the arrl.net forwarding service and you are a current active member of ARRL. Example of a bounce message: c-pb-mx-quonix.pobox.com rejected your message to the following e-mail addresses: w6dmg@arrl.net (w6dmg@arrl.net) c-pb-mx-quonix.pobox.com gave this error: : Recipient address rejected: User unknown Note: Average spam messages per @arrl.net alias per day are between 5 - 10 messages. ARRL does not filter @arrl.net aliases on a per user basis. If you find that you are receiving excess of 10 messages per day, please e-mail itstaff@arrl.org. Please remember that not all spam going into your e-mail inbox is from the arrl.net forwarding service. Examination of the header information is needed to find if the message came through the arrl.net forwarding service. Note: If you find that mail is slow to be delivered or seems to be completely down please visit https://twitter.com/pobox to find out what may be happening with our third party arrl.net provider. Why doesn’t my arrl.net address work when I try to test it? Note: If a message is sent from the same address that is receiving the message (ie your arrl.net destination address), it is very likely that the message will be silently deleted. This happens to prevent spam from being sent with forged mail headers or to prevent the possibility of the message looping. This filtering is being done by the sending and/or receiving ISPs and NOT by ARRL, therefore ARRL has no control over what occurs with these messages. Note: Over time ARRL has seen an increasing number of ISP’s implementing these checks, and the responding to the situation in different ways. Some silently drop messages, others might generate a rejection or bounce message. Some have even taken the steps of banning future messages from the same email address or even email server. For further assistance with your @arrl.net forwarding service, Contact Us. |

| Space-limited inverted V advice needed | KA6CHX | 1 week, 2 days ago |
| I would suggest getting it as high as possible. If you have supports 50 feet apart, you can run support ropes roughly 14' long to get the antenna ends about 20' in the air. I'd suggest starting out with about 34' on each side, which is a little more than the usual 66 feet for a flat top dipole. The SWR bandwidth narrows, but this may be better than the alternatives.

| Most likely FT8, which is typically transmitted using USB and a suppressed carrier frequency of 3573 kHz. It can be decoded with WSJT. Zak W1VT ARRL Senior Lab Engineer |
