I went through all the bands to document it against my 80M EFHW prior to attempting to repair it. 1850 - 3.71:1 3550 - 1.22:1 5405 - 1.75:1 7050 - 1.93:1 10110 - 1.95:1 14.050 - 2.82:1 18080 -

I'm also having tune problems with my ATU-10. I found a few workmanship issues, the main ones being excess solder on several of the shunt capacitors and tiny balls of solder lodged between a few of

I experienced something similar during the construction of an SDR tcvr. Soldering small relays can be critical. In the case of the BPF circuit, I found that one of the relays in the 40M band was not

Hi all. I Have purchased a ATU-1000 kit. Does anyone know or have a good source where i can find instructions how to adjust/calibrate the swr bridge with the 2 potentiometers? 73 Bj?rn de

Dear Glenn, The longest keypress brings it into a power-down mode, the unit does not react on anything but the next longest keypress. No RF-power will wake it up from there. It is only the 30-minutes

Hi Tony, yes you are correct, a short press resets the relays to 'bypass' mode (reset mode more accurately) ......AND..... if, like me you fit a power on/off switch to the ATU-10 which is wired across

Dear Glenn, That is a mistake to say that the switched-off ATU-10 (with the f/w v1.4) resets its' relays. I'm looking at the v1.4 sources ( https://github.com/Paguo-76M2/N7DDC_ATU-10-w-AD8361 )

Please calm down. :) Oh yes so sorry, no spank me Daddy :) Not everyone building/buying ATU-10 have ICOMs. Exactly its true,?in this case why talk about icom then? A cable would be mandatory if

Dear Patrick, Please calm down. :) Not everyone building/buying ATU-10 have ICOMs. A cable would be mandatory if ATU-10 were compatible with ANY brand of transceivers out there. Regards, Tony

Dear Gyula, Sure I'll report my experience with this ATU and my modification of it. So far I'm still in the process of obtaining the proper capacitors' values, - have got only several of the

NO!? Its like you say you cant use Heil Headset because its not ICOM! The software reconize the 705! Its made for it! Read all the the documentation about ATU-10! 73 Patrick > >

Does the communication failure occur on a specific band? You can't rule out RFI, even at QRP levels. As the ATU-10 isn't an Icom-exclusive accessory, it doesn't make sense to include the cable with

Hello Tony, would you be interested in how qrp ATU works in practice? What is the power you can still tune in to? If you have the opportunity, please do so and report it. If you have more than one

Barry A long press on the function button RESETS all relays to the default state, which is essentially bypass. See my Schematic link on N7DDC's Github. It shows all relays in reset position.

Barry,I'm no expert on these (only recently received mine) but I thought they could only be bought from Chinese companies, so the interface cable would be down to the suppliers, none of which are

I suspect you might be able to copy the set-up file for the? 1829 and then modify it to cope with the double memory size. Most programmers, and I'm hoping the TL866 also, use a set-up file for each

Thank you for your answer. However, the hardware of the ATU-100 is normal. Because it works fine with the original firmware (N7DDC version). 2022年6月5日(日) 11:23 David Fainitski

Hello, As I don't have a PicKit3, I tried my MiniPro TL866-II Plus universal programmer on the ATU-100, using ICSP access. Reading the Flash and Eeprom seems to work perfectly, but as the current
