ok but i see no way on that schematic how to get the dc out from the coax to power the atu,am i missing something apart from my marbles? lol.73 m3vuv.

Hello Paul, No, this is VERY FAR from what you need. It is made for receiving purposes and it cannot handle any transmit power. You will need something that can handle the power, a bit like the

Hi all i want to place my atu-100 at the feedpoint of my doublet,i am looking at a bias "T" to power it,would this do the job?

I got this one,only issue was the pic was locked,not a big issue tho,cant beat it for the price!

Hello Paul, No, RC7 and RC6 are already used in capacitor switching. This would require David to redo lots of code, but if he does, I can do another version with RS485 on a PCB. In general my idea is

One option, and what I would do now that I have built one, is order all the parts for 10 and sell 9 kits. It spreads out the shipping cost and 9 other people get a chance to build. Taping SMDs onto a

Hi?Russell, Thanks a lot for your opinion! Seems you were more lucky than me. I once had problems and only got?automatic, but misleading replies. Anyways, I just wrote a message to Up Tech Store,

Can we make sure the UART is pinned out so there can be the option of having a remote control using RS485?

Hello! My name is Bill, LZ1SWE. I have reworked the control board using PIC16F1938 and MIC2981/82 as drivers, dispensing of the myriad of transistors to drive the relays. This simplified the PCB and

My opinion only, but if you want to buy from newdiytech, I would use their Aliexpress store, which is uptech. I have found that the buyer protection on Aliexpress is pretty good, as long as you are

I'm looking for an ATU-10 kit (preferably) or build. Since I didn't find a kit, I was looking where to buy an already built ATU-10. I read some recommendations for newdiytech.com that is also an

No problem! Happy anniversary to Copernicus. We discussed he work in a Physics class. 73 Mike N2MS

I was having trouble with my ATU tuning on 15 M and above. It would attempt to tune, but the display would reset and the tuner would repeatably attempt to re-tune. Tuning on the lower bands was quick

I have now? completed the QRP mod.? Thanks again for all your help. Having just gone through this I have a couple of suggestions that may be useful? for those new to this as I was. For hardware I

Thank you for the help. Was? nervous about reflashing the PIC since the the current settings are blocked (all 00). Good to go from here. 73

Hi. You have to configure first sells for oled using. The tuner uses LCD 2x16 by default. Read the manual above for more info.

hi Francis, a good help may be the manual to the ATU100 (I append) for 10W you should use 5 turns on the bridge, 7 turns for 50W. Any case you should verify the settings of the eeprom-cells following

I am working on doing the QRP mod for the ATU100 kit I have built.? Like others I have encountered the problem where the PIC was locked when programmed so it will require a re-flash using the hex
