Re: Delayed long packets sent
Hi Stephen,
This is on TX packets from my iGate rather than RX packets to my iGate. My KPC-3 saves them up and then send all the TX packets at random intervals. If I quickly power cycle the radio, it resolves it for a few, but comes right back in no time. Thanks again! -Scott KD4YDD ________________________________ From: ui-view@... <ui-view@...> on behalf of 'Stephen H. Smith' wa8lmf@...

Re: Delayed long packets sent
Hi Lynn,
Thanks for the email. The KPC-3 is hooked to a monoband Kenwood TM-231a. Interestingly, the Rcv light is always green. Is that normal? The squelch is tight, I am not in a high RF area aside from my other dabblings in the hobby. It is located at my QTH. At a loss. And Bill, yes it is KD4YDD-1. I will try the reset procedure later. I am so close to throwing in the towel. Thanks everyone! -Scott KD4YDD ________________________________ From: ui-view@... <ui-view@...> on behalf of 'Lynn W. Deffenbaugh (Mr)' ldeffenb@...

Re: Delayed long packets sent
You didn't say which SSID this is affecting.
I assume it's the KD4YDD-1, but that callsign is beaconing only on internet it appears. Assuming the radio squelch is closed, have you tried resetting the TNC? I generally run these TNCs with the backup battery removed. I know that requires a full selection of baud rate and mode etc if there's a power glitch, but my experience is that the Kantronics tend to get hung up after a day or two's operation. (see ) Anyway, good luck! Let us know if you discover the solution. 73 Bill W1WAB |
Re: Delayed long packets sent
Have you changed the battery inside? they are sensible to that if they are no change at least once a year.
mine lost all there data one time, you should equal the ground with the radio (put a cable between the outside of the tnc and the ground of your radio i used to have 2 as nodes,,, finally i turn them off and baught MFJ and converted them as UIdigi Kantronics did not won the lotery with these kpc3 gervais ve2ckn ________________________________ De : ui-view@... <ui-view@...> de la part de 'Lynn W.

File - Posting guidelines
The UI-View Group is very active. Most already do so,
but here are some some guidelines to follow. 1. Civility... this is practiced well by our members! 2. Sign your messages with your name and callsign. 3. Only post messages and responses that are relevant to UI-View. 4. Use plain text for messages sent to the UI-View support list. When you address some 5000 recipients, you cannot know what their email readers do with HTML formatted messages. Some will experience unreadability. 5. IMPORTANT: When replying to a posting (message), kindly delete all unnecessary text including the trailing text. Only leave the poster's name, callsign and the time stamp, and the text from the prior message about which you are commenting, and then trim the rest. When viewing messages in the Yahoo web based interface, the command [Up Thread] at the top of the message can be used, and many email clients can group messages by thread also. Some members have slow connections or pay for bandwidth. Brevity can often also improve the clarity of your message. Do not top post... i.e. do not type your reply above the quoted text. 6. When replying to a post, please decide if your comment should go to the entire group of about 5000 or directly to the author. Please think before replying to the group... replies like "I sure do agree with that" do not add much to the group. Send thoughts like those directly to the poster please. 7. Postings of sale or swapping of items are not wanted. 8. New members are all moderated for a number of postings. If the messages follow the guidelines, they are approved and the member is changed to un-moderated status. This is a partially moderated list, i.e., only the user's first messages are moderated, but all messages are monitored after posting. If an un-moderated posting is found by the moderators to have a problem, then the poster is changed to moderated status and in most cases also contacted directly to resolve whatever has caused the problem. Actions are taken against those that chronically violate the rules. The reason for this form of moderation is to block spammers from the list and it is working well. 9. Do not add disclaimers to your posts that (1) restrict the ability of other members to use the information you post, (2) claim a copyright to your post, or (3) to claim any type of "rights" as a consequence of another member replying to your post either directly to you or to the group. 10. Do not use anti-spam tools like challenge/response; the moderators will not respond, and since messages to you then will bounce, you most probably will be removed as a user of the group. |
File - About Bouncing (Admin message)
This message is sent to all new members, and to all members
every now and then. It has been revised as bounce reports have changed a bit. Any of us could experience no longer receiving email from the UI-View support list. You might want to print this message and review it if you stop receiving messages from the UI-View list. If you stop receiving messages from the UI-View list, suspect that either... 1) this or some other Yahoo group that you are a member of is sending email which some spamblocker system regard as spam or junk mail (quite a lot of these reports since summer 2009). 2) it may be that your email account has filled up with unread messages or that the account on your mail server has ran out of storage space. Read or delete the old messages on your mail server. 3) Some MSN or Hotmail accounts, and others such as arrl.net, qsl.net which are used as a forwarding address from time to time cannot forward to your primary address. When this hapens, the Yahoo group receives an error message with something like "impossible to relay to xxx" and you are then in the "bounced" list. There are increasing numbers of bounces from some service providers about messages which are blocked by them for policy reasons. 4) You or your email provider have set up a challenge-and-response system for those sending e-mail to you. The moderators will not send replies to such challenges. You should select another address for your list membership(s). Sorry, but we cannot investigate every one of these blockings. Please be aware that if you haven't received list messages for some days, and reactivation requests are not reaching you, or not answered by you, your account at the UI-View list may be deleted. It may deleted if several bounces occur in less than a week or two. It will also be deleted if the bounce report says that your address is invalid, discontinued, or unknown. Be aware that the bounce can relate to messages from other lists than the UI-View list if you are a member of other Yahoo groups. If your membership is deleted, you will not be able to log into the Yahoo group. If you try and send email to the group, it will be rejected. However, you can subscribe again with a valid and working email account by sending an empty email to ui-view-subscribe@.... If you are away for some time, you might want to set your account to temporarily receive only special messages or even no email at all, but we recommend that still receive special messages. You can log into the Yahoo group when you return and change it back to daily digest or normal email. Note: A member may send reactivation requests to himself/herself from the Email Preferences section of My Groups. 73 and good luck - your UI-View group moderators |
