Picked mine up from NewDIYTech.com Good build quality. Prefer my T1 but the ATU-10 is great for the price and availability. Not to mention it’s feature set.?

You can see some of my testing here:?

Hi, Stig

Hi Stephan,

I strongly recommend KN5L method, if you are still looking for 6m band make primary connections as short as possible.

I tested my repaired ATU-10 with Long Wire antenna in the garden and it worked with SWR below 1.5:1 on all bands from 80 to 10. I am using 9:1 on FT140-43 3x7 turns and 12.5mtr (41feet) wire. The big test will be this Sunday when I plant to use it for SOTA activation on local hill. You never know we might have S2S.

I will post results next week.

Hi Rod.

I have purges the AT-15 variant, but this drains the battery twice as fast in OFF, as when it is ON, so stay away from this model.

Any recommendations for best outlets from which to purchase an ATU-10?
Any to avoid?

If any have had relevant experience with one of these and a FT-818 I'm all ears.?

Thanks.

Well it now has a semi working display,looks like an iffy dupont lead connector,i hate them with a vengance,total crappy idea!.

well i have used an arduino uno with a test sketch,all my oled displays work fine,need to hunt down my programer now,at least i now know the displays are ok,can rf corupt the pic fw on these?.73 m3vuv

i get nothing like that,just a brief spike at turn on and nothing,i have 2 of these both do the same,need to find my pickit3 and read them.one of these is new just the diode caps +vreg+headers fitted,seems dead,bit odd tho,first one was ok untill the cap fried,was still showing data on the display tho when it was disconnected to check over,its very odd.73

Thanks Marek, for your information! The KN5L method looks really interesting, maybe I'll try it with a core I have at hand.

Some days ago, I received the ATU-10 from the Aliexpress Uptech Store. I checked it on the bench and all seems fine (I didn't even had to open it).?

Today I experimented with the ATU-10 on a summit, but to summarize, I wasn't convinced, mainly because of the small tuning range. But also how to quickly mount it on the telescopic pole and other small annoyances that I'm not used to.

I have to think about a different setup.

the order was for 5x smd caps that would fit in a normal envelope,whats a first class stamp about ?1 say 40p for the envelope,so a markup of ?11.50 ish,they can ram it! up there @rss

Hi,i am trying to find out why my atu 100 display dont work,what scope traces should i see on the clk and data lines?,on mine i have brief activity on turn on then nothing.cheers.

I've also dealt with LCSC for components when I ran a group purchase for partially assembled (tr)u-SDX boards, and DL2MAN bases his BOM mostly on LCSC part numbers. I recall the shipping being relatively cheap and they do seem to have a pretty good selection of parts, as long as you exercise due diligence.

Just throwing it out there as a possible alternative...

It's a $60 AUD threshhold here in Australia and I received my most recent order within 4 days of being placed, from the US with the final leg being undertaken by Australia Post. Unbelievable service and in stark contrast with the order I received from Element14 (Farnell) yesterday. That was ordered back on 22 February. When I questioned its non-arrival I was advised on 9 March that the parts were ready to be shipped but even then it took a further 13 days to have them actually arrive and that was only from Sydney.

Hi Paul,
Not sure which firmware you are using, but the EEPROM defaults for the N7DDC software is not set for the OLED display, but if it is a kit, I would expect it should have been updated accordingly prior to shipping.
Generally for the OLED display, EEPROM Addr 0x00 = 78 and Addr 0x01 = 05.
Yes, the display should work with just the reverse voltage protection diode and regulator fitted, that's how I initially tested the kit I received.
Just double check the connections between the ATU and the OLED are correct.

yes it was working ok,i cant find my pikit3 to check yet,i have another kit,i have fitted the vreg diode and caps,that does nothing on the display either,i havent fitted relays or torroids yet but guess it should display something,i have tried 3 oled displays so far all look dead.

I don't know if they normally offer free shipping. What they have is a minimum shipping. Mouser has $7.99 for small orders. When I order small parts this price usually covers the order.
