I'm blind so I have to ask... split core as in two halves split down the middle, and you just pass the cable through the hole?

One of the cores I mentioned isavailable from Mouser. https://www.mouser.com/ProductDetail/28B1020-100 ( https://www.mouser.com/ProductDetail/28B1020-100 ) The split core is available from Digikey

One of the wall warts I tested is an Inland (Bought at Microcenter).? It has a small core on it near the Pi.? It has the same problem.? The core is too small and in the wrong place for this

I use a CanaKit 5Vdc? 2.5A Wall Wart power supply with my Shari and I have not noticed any hum! But it does have a ferrite filter core as part of the power supply cable near the end that plugs into

Thanks for this! I need to buy some ferrite filters like you describe below. What's the best source for a bunch of them cheap?? Amazon? eBay? One of the online ham radio retailers? Thanks again for

Ferrites are our friends! -- The views I present are that of my own and NOT of any organisation I may belong to. 73 de Simon, VK3XEM.

I have performed additional testing to better understand the buzz phenomena. I fabricated a current probe that measures the current on the power supply cable and cabled it to an HP8901 modulation

I used a raspberry pi 3 for my uhf repeater and vhf simplex node. I use a 12v automotive USB power outlet to power the pi 3. Once I get my SHARI-U. I'll test it out. Thanks, David

My node from G7RPG has the hum, but that is usually eliminated if I listen carefully while moving it a few inches this way or that on the desk.

I find this assessment a real ear-opener. I've always been able to detect who has a Shari node and who has something else, because almost to a fault, those stations using a Shari have the buzz. I

Thank you for the in-depth and very fast answer. Much appreciated ! I'll try some of the above and report back once I find a good home for the SHARI, away from all the internet router and everything

If I understood the question right, yes I've experienced that as well on my units.I found that putting a ferrite on the USB power cable and Ethernet cable seems to resolve the issue.

Hi Quentin, I have just completed an investigation into this issue as I experience it here also.? I am writing a report which I will share with the groups in a few days. Basically the problem is

Hi all, I got my SHARI in the mail last week, and it's up and running as of this morning. I really like the build quality and the clear, detailed instructions. When I connect to my local repeater's

Thanks. That is what I was looking for. Ordered a couple of short USB extension cables. Now if I just had the SHARI...

Thanks. I have tried to find a power bank that will run and charge at the same time, but have been unsuccessful. I have a drawer full to prove it! Do you have the brand or a link for one like you

The settings are on pages 12 and 13 of the SHARI Allstar Node Setup Procedure in the Files section of this group.? There is also a document on "Setting the RX Level in HamVOIP Allstar in the Files

I have a new Shari 3U set up and running. It's quite impressive and was very easy to set up. The next step here is configuring better audio settings. I have the recommended settings for the Allstar

Battery will run a day half continuous. No special treatment done to conserve battery. I also like this battery as yuou can charge it while powered up . So I can charge during day while working . I

Very cool.? How long does a battery pack last.? Did you do any special configuration of the Pi to reduce its power requirements?
