TOPIC: Internal ATU Setup

Internal ATU Setup 23 Jul 2022 23:12 #1

Hi all,
I've acquired an older MB1 (I5 setup) to use in addition to my existing SDRpro2. As my MB1 has had several previous owners I decided to totally rebuild the Software. A fresh clean copy of Win 10 Enterprise was installed along with the latest vesion of SDR2 for the MB1. Everything works fine EXCEPT the internal ATU....which just cannot find a match, even when connected directly to a 50 ohm dummy load... So my question is ...... are there any undocumented setups for the internal ATU... the ATU firmware shows as version 6 which my machine reports as the latest version.. Also it was previously suggested to me by another HAM that the internal ATU is infact an LDG unit ? Can anyone confirm this...
I'm hoping I'm not going to have to start repairing the ATU next , so hopefully it's just going to be a configuration error on my part..

Regards Paul

Hello, Paul.
What is the s/n of your MB1?
Please record a video of tuner operation and send it to our email.

We have our own tuner models inside MB1 and external one for SS2DX, we've never used LDG tuners.
