Recently, my repeater at 42690 began developing an audio ' hum ' . An Asterisk restart does not stop it. A reboot is required. It is NOT power supply related. I tried substitute supplies for the Pi and Repeater. The message log shows not related errors. It is software related somehow. [ short audio file attached ] Len WB2HKK
Look for a bad ground .. I had one found that the grounding system had a corrosive connection. On 9/19/2018 7:49 AM, lengriff@optimum.net wrote:

Also make sure that rpt.conf is set up properly. Make sure your not transmitting PL tone mixed on your audio. That happened to a friend of mine On Wed, Sep 19, 2018, 7:50 AM lengriff@optimum.net <lengriff@optimum.net> wrote:

Going out on a limb here a bit... If it does not look like a normal 'ground' type of audio hum... If your exciter on your tx'r is synthesized, it may be a digital ground issue of sorts if the clock from it is making noise on your audio lines. something to look for. let us know what you find if anything ...mike/kb8jnm On 9/19/2018 10:49 AM, lengriff@optimum.net wrote:

I have not seen anything to do with PL in rpt.conf. Can you please point me in the right direction.

PL or CTCSS settings are in the xxxusb.conf file. Make sure there is no value listed there On Wed, Sep 19, 2018, 8:19 PM David <david@kg5rdf.com> wrote:
