Yannig, What Ellis suggested is what I use with about a 50 ft (15m) run of cat 6 Ethernet cable. Works great! ?In my case I also get the power where I need it with coax bias tees. The guide

Hello all, I've ordered an ATU 100 to install on a boat. The ATU will be right at the bottom of the antenna which is about 5m away to the TRX. Can the OLED work at the end of such a long cable run ? I

Marek When you use the relay test program, you need to verify that the relay that is being tested is actually working. You need to use an ohm meter across the contacts to see if the changeover occurs

Yikes, that's the wrong YEAR! mike KO4BCN

No problem. I'm a happy owner of one of the Barb-A-Watts, its the least I could do.

Thanks Don. I ordered the 8 parts from Digi-Key (price is higher than it was before). Mouser said their delivery was scheduled for 2023 (was 2022 earlier). 73 Kees K5BCQ

Looks like digikey has plenty: https://www.digikey.com/en/products/detail/microchip-technology/PIC16F1938-I-SP/2258599

I loaded Relay Testing software and by pressing TUNE I can hear relay clicking and going through C values to L values and SW/IN SW/OUT. I don't see C or L values though as it is on ATU-100. Is this

Hi All, I purchased some time ago ATU-10 on Aliexpress but haven't used it till now. I have 1.4 firmware which I upgraded from 1.3. Testing tuning using 50ohm dummy load I get following results 80 SWR

Mouser is expecting the DIP package any day. Only a few thousand so you would have to be on top of the order. Colin K6JTH

I'm looking for a total of 8? 28 pin? PIC 16F1938 DIP parts to complete a kit build of Barb-A-Watt meters. The parts shortages have really cut into these. 73 Kees K5BCQ

Many thanks Glenn. Dave, W0DF

Sorry for the troubles. Glenn

Thank you Glenn!

Apologies for that. Seems I sorted the Xcel spreadsheet but didn't include the left column in the sort...... Duh If you use the Link from N7DDC's Github, it should now be corrected.

I am going through the same issue. It looks like the sheet was sorted and was not quite corrected. I am at a standstill on mine because I decided I needed to check the BOM against the schematic and

I'm finally getting around to building up the V1.3 version of the ATU-10 PCB that I bought from Kees.? Can someone explain to me why the BOM sometimes calls for more than the quantity of components

I replaced both the toroids and caps, which made the thing quite a bit more expensive. I wish I had just got the PCB and put all the parts on myself. As an example the UHF connectors you will get from
