so how do i find where it says n7ddc etc,all i see is a load of hex code 'ff's etc,do i need special s/w,if so where do i get it from?,73+ thanks m3vuv.

i was more concerened with no hex/fw files listed,not everyone wants to trawl thry github,on here would be better more convenient.imho.

Hi all,i see some vids on yt showing the atu 100-m,it has a graphing display,is there any firmware to make the atu 100 do the same?,thanks in advance m3vuv.

Hi, Bob No, that's too much.

I have read that IC-705 owners use the ATU-10.? Does it tune for the 6 meter band? 73, Bob? W7DIT

Hi David, Excellent, the good old low level editing. 73, Dave

Hi, Dave. There is some much easier way. Just open hex in Pickit3 software, find "N7DDC" sequence in the code, change it, profit. The alphabet of hacking.

Hi Clive, The original firmware for the ATU-100 and its derivatives was developed by N7DDC, hence it is reasonable that this is displayed on the boot up screen. The code is available in github, but

I wanted to do the same but could see no way to do it,its pretty easy with arduino based things but pic?,seems to be a different kettle of fish!.

Is there away to edit the boot up screen so it shows my callsign...?

Ed, thanks for that info! I had big and have now smaller issues on upper frequencies, mainly on 10m and had shielded the cable connections with aluminium tape. I'll give your hint with the cat6 cable

Oh, and don't forget - your output harmonic filter is what it is when loaded on both sides with around 50R resistive. In all other cases it becomes an impedance transformer, which might, under certain

Well, great! The display wires resonated and became antennas, common case. The world of stray currents, the destiny of the RF engineer! :) Actually feedtrough caps should be used one side only, as not

Bilyan, Thank you for the response and suggestions. I was ultimately able to determine that the issues I was having were related to the display, or rather the cabling for the display. I found that

Hello Ed, This ATU is not designed with any EMI foresight. To get it working in an RF intense environment you have to filter and shield the CPU part almost totally, especially if you have an amplifier

Hello, I'm trying to integrate the ATU-100 into a 100W SDR-based transceiver. I'm finding that if I have the ATU too close to the amplifier (anywhere inside the same enclosure) I start to see lots of

Harvey, Where did you get the PCBs of the correct size? I'm having issues with my ATU-100 which I think may be RFI related and I'm interested in this potential fix. Do you have pictures of the

What comes to my mind is: - Higher current/voltage relays. - Larger Inductor cores to deal with the heat - More capacitors and/or higher voltage capacitors - Larger diameter inductor wire - Wider and

Good evening, I am working on an LDMOS amp, I would like to integrate the ATU100 into the amp for an "All in one" kind of system. My first step is to make sure the ATU100 can handle the power... I

Okay. Thanks for the response. 73, Steve kf7o
