Throwaway for some obvious reasons, but I work at Sennheiser and I think this is awesome! Personal opinion, and not speaking for the company.

A small disclaimer: operating modified RF devices can, in some jurisdictions and depending on the impact of your modification, put you in contradiction of the law.

From the manual: "Your SKM 3072-U hand-held transmitter can be operated on one of up to 32 different frequencies. These frequencies and their sequence are pre-programmed by the factory and must only be changed by your Sennheiser distributor who has the required specialist equipment."

You may be surprised, but I just checked with some colleagues, we still have the software (SePT.exe) around as well as the service cable. :) I am not sure the last time we performed that service though!

I like Sennheiser because they make at least some stuff still in Europe (vs. many competitors who pretty much live off of made in china copies of classic designs). It's just weird that Sennheiser is very quiet about it, they used to have a "MADE IN GERMANY" on a lot of stuff, directly silk-screened or molded into cases etc. -- this has disappeared. At first I suspected that production for these products was offshored, but it wasn't (still says Made in Germany in the fine-print). Kinda odd.

Complete guess here but I would suspect that means some items are made in Germany and some are made in China or elsewhere (meaning, even the same model may be produced in both locations). If they are printing "MADE IN GERMANY" directly on it then it will be obvious which ones aren't, because they would lack the print. And that would likely degrade the perceived quality of those not made in Germany vs those that are. And Sennheiser doesn't want you to think that some of their items are built with better quality than others.

Of course, people can look at the fine-print and determine where it was made. But that's a lot less obvious than the silk screened badge not being there.

Hi, yes. i know Sennheiser have SePT.exe software. however, this software has been "death" for everyone. I have changed my SKM3072 from 638-670 MHz to 668-674 MHz successfully by myself with a small eeprom tool and ...Excel.

Hi, thats amazing! I was trying if it would be possible to find the software or the cables somewhere hidden on web. But it's looks like there is nothing. This was actually the motivation for the blogpost in case someone want to the same thing, so he can get the informations.

What is the RF output power of these devices?

According to the specification, 30 mW[0]
