Hi Jens , I guess the shipment is on hold awaiting rework right ? keep us posted :)

That is correct.
I expect to get the PCB's for the modification tomorrow (Thursday). The plan is to do the SMT mounting as soon as the PCB's arrive here and hopefully we can have a small number of units modified and tested tomorrow as well. If all goes well, we should be able to resume shipment on Friday to those who have already paid.

Once we have some units ready, we will also take a picture of the modification. I expect that we will send a picture and a description of the modification to those who have already received their RTX6001. From that, it should be possible for each individual to estimate whether that is something that can be handled as diy or whether the unit needs to go back to RTX.

Modifications are ongoing at the moment. Shipment will resume by Monday next week.

For those who have already received their RTX6001, I have made a description of the modifications needed to improve the distortion at high input levels.

Please take a look at it and report back if this is something you feel that you are able to do yourself. If so, we will send two mounted PCB's for each Analyzer.
I assume most people on this forum will be able to do the modification, avoiding shipping the unit back and forth. Using a solder iron with a fine tip will be an advantage.

JensH, it seems very easy and simple the modification.
I dοn't think, it can make it difficult for DIY members.

Hello Jens, i do think as well that most of the participants here should be very capable to do so. My only question would be if warranty would be affected by this mod performed by users.

Cwtim01, it is better to modifiy the one channel and compare it to other unmodified channel.

Actually it would be better to do a sweep of each channel before and after modification, that way you can do it all at one time, and you are not comparing channel A to channel B, but can directly observe the improvement on each channel. It should be clear that the test must be performed with the same software and settings both times.

It's also perfectly valid to just check it after completing the modifications to verify that the modification was performed correctly.

For those of us in North America I would probably recommend Kynar or teflon 30awg wire wrap wire for the modification, unless the retrofit already includes the wire.
