Hi, The node that I built for a Baofeng UV5R is not the cleanest sounding in the world. There is a slightly perceptible "buzzing" on TX audio. It doesn't get a lot of use and its purpose in life is as part of an emcomm system. The speech itself comes over sifficiently clear so I haven't tried anything yet to cure it. This one uses the DMK URI and is built into a Hammond diecast box. You can see photos of it at http://www.feednet.org.uk/remotebase.htm 73 Bernie GM4WZG -----Original Message----- From: app_rpt-users-bounces@ohnosec.org [mailto:app_rpt-users-bounces@ohnosec.org] On Behalf Of app_rpt-users-request@ohnosec.org Sent: 03 November 2015 17:00 To: app_rpt-users@ohnosec.org Subject: App_rpt-users Digest, Vol 81, Issue 17 Send App_rpt-users mailing list submissions to app_rpt-users@ohnosec.org To subscribe or unsubscribe via the World Wide Web, visit http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users or, via email, send a message with subject or body 'help' to app_rpt-users-request@ohnosec.org You can reach the person managing the list at app_rpt-users-owner@ohnosec.org When replying, please edit your Subject line so it is more specific than "Re: Contents of App_rpt-users digest..."

Message-ID: <CAJNyT09tu=M13ZxTLWPA+mo9LPKOqE39Qmx3yMGvr1FqzVq5LA@mail.gmail.com> Content-Type: text/plain; charset="utf-8" To this day every Baofeng Node with a modified sound fob I have built has had some RF problem or another. The first node had a horrible bus noise whine through the transmit audio. My next nodes have weird issues, where when the transmitter drops, the node double-keys or even triple-keys, and I hear the courtesy beep a few times. Lastly, the sound fob is giving me a lot of RF noise on all UHF frequencies while my node is not transmitting and will break a Carrier Squelch handheld if the HT is within 5 feet or so of the node. How does this node not have any problems?: http://www.kg5ebi.com/uncategorized/the-smallest-all-star-node/ What is the best way to kill this RF issue? Skyler KD0WHB
