Added Audix Performance R41/R42 and R61/R62 series to excel. |

@tapakj, I've just released version V1.6.1 which contains the new frequency ranges. Have fun. :-) |
|
Hi, love this software. It's a great way to connect to the rf explorer with just the features we need as audio people. My one suggestion would be to be able to set a more detailed rbw (ie more scann points). Please find info on the Australian RF situation attached. |
@petejonessound, thanks for your contribution. I'll add the data asap. Unfortunately the number of scan points is limited by the hardware to 112 point for the handheld devices and to 224 points on the RackPro. Thus I can only show what the hardware is willing to give me. ;-) |

Hi Bernd
I think you can now change the number of points. In the RF Explorer for
windows software you can go to the "device" menu and there is an option to
"define sweep points" which allows you to select up to 2048. In Touchstone
you can also set the RBW directly, although I think it does this by
performing multiple smaller sweeps.
I admit I have no concept of how difficult this might be to implement as I
have basically no coding skills.
Thanks again, really cool that you put the time into this project.

Hi Pete, Thanks for that hint I was not aware of that feature. But I checked and according to the release notes for version software v2.3.2101, it looks like this mode is only available for specific devices (WSUB1G PLUS and ProAudio spectrum analyzers). In my case that option in the menu is there, but grayed out. I have the WSUB3G, but not the PLUS version. Indeed it would be an interesting idea to scan with a very small span e.g. 10 times and thus get 112 * 10 sweep points. The only problem is that at least on my device one single sweep takes a (short) time (depending on the span size). Thus multiplying that time by 10 would surely not show a graph moving in real time anymore. By the way, do you also have a list of forbidden frequency ranges for Australia? Im asking because that is the basis for my tool. If there is no such data available for a specific country, currently it is currently not possible to switch to that country, even though TV-channel data is available. I will probably change that in future, but for now I need such data. In worst case I could take over the data from another country (does US data fit somehow?) or I can simply enter an invisible dummy range. |

Hi Bernd
Ah Ok, I have a WSUB1G+, I didn't know some of them didn't do that. The way
I usually use the RF Explorer is to do multiple continuous scans over a
period, and use the peak hold trace, so a slower rate isn't a problem.
The frequencies I gave you are the ones allowed In Australia, so all other
frequencies are forbidden. The broadcast TV channels are different in each
state capital city, those are the ones marked in orange, but they are not
forbidden as such. These are only really valid for the centre of those
cities, and regional towns and outer suburbs may have a different TV
situation, but the overall bands allowed are the same. There is a lot more
spectrum available here than the US and Europe.
This is the official government page which describes the situation if that
helps : https://www.acma.gov.au/wireless-microphones.
Yes we are still able to have some events, but only with small audiences in
person. We are still doing a lot of webcasts and online events though.

Hi Pete,
nice to hear that you my tool. I used it a lot myself, for my the events
where I was playing as a DJ ... before Corona. ;-) I heard that Australia
is handling the crisis quite well. So you are probably allowed to have
parties again.

Hi Pete, that's an interesting way how you are doing the scans indeed. I'll think of how I can implement such a specific mode. Could be quite useful. I was wondering already why in US most audio engineers are dealing with TV-channels. So it looks like its the same in Australia. As I understand such frequencies are allowed to be used if not occupied by TV in that region. No way, here in Germany. :-) Here everything that's not allowed is forbidden. ;-) I still have an older Sennheiser system which uses frequencies which meanwhile have been dedicated to LTE. So there is just about 1-2 MHz which I can use at the border of the systems frequency range without interfering with LTE. Officially that's an LTE guard range and should/must not be used for wireless mics anymore. But to be honest ... on weddings you need the mic for 5min for the father of the bride. ;-) So I'm scanning with RF-Explorer if there is an LTE carrier in range. If not, I don't bother. If yes, they have to take a cable mic. ;-) |

Hi Bernd
Yes so in Germany the spectrum will still be shared around the TV channels,
however I guess it's similar to the UK (where i am originally from), where
there is only a very small band of frequencies for free use and then there
are licences for other parts of the UHF spectrum which hire companies pay
for, as well as site-specific licences for events which you can purchase
from the regulator.
In the US I think there is free use around the TV channels, but NOT the LTE
bands. They have sold off a lot of spectrum to LTE in the last few years
and it is a struggle there now. Also certain people can get a special
licence if they coordinate upwards of like 50 (?) channels frequently,
which allows them to make other users fit into their coordination.
In Australia we are lucky enough to have plenty of spectrum (at the moment
- we are normally about 10 years behind UK and Europe) and very little
regulation, apart from we must not interfere with TV signals. With a 10mW
transmitter this is extremely unlikely anyway.
If you are interested this is a good video on how to coordinate multiple
frequencies.

I use the same process but I also use the RF explorer to scan for a longer
time then import the scan to Wireless Workbench, and also to scan any bands
where the gear I'm using can't scan. I also tend to monitor the situation
using the RF Explorer to make sure nothing else pops up. On Monday I was
able to see that a rehearsal had started in a nearby venue between our
setup and the show, so I changed a couple of our frequencies to avoid any
problems.
Hope that helps

Hi! I am a new radio enthusiast and sound engineer, I really need the preset frequency of AUDIX wireless microphone, I hope you can update it! Thanks again. |

Hi, Croatian regulation site related to RF spectrum from which I extracted TXT file: https://www.hakom.hr/en/radio-frequency-spectrum-database/242 more detailed database (has some mic ranges "search for 'microphones' " inside but I think that mobile/radio/TV are main nonoverlaping events): http://tablice.hakom.hr:8080/vis?lang=en br, |

Hi @moreben2023 I'm very happy to hear that my little tool is useful for you. Your contribution is very welcome. I'll create a new release with the data for Croatia asap. Regards, |

Hi berkon, |
|
Hi there, Thanks for your work on an incredible app! The UK TV channel grid doesn't seem to display, so I'm wondering if you have included the data for it? Information can be found here Thanks again |
|
Thanks a lot @split-face, your welcome! I'll add the UK TV channel grid in the next release. |
|
Hi there, I thought I would help out with the frequency planning in Belgium. The overall frequency plan can be found here (available in German if needed): Since the tool is designed around wireless microphones, the most important information can be found in this PDF: Green channels are free to use. |
|
Thanks a lot @leo-benjamin! |
|
hi @berkon, I do have the current assigned slots for mobile phone in Austria Thanks for your software! |

Hi @OE1MWW, the .pak files which you found are language files of the "Electron" framework on which my app is based on. Thus they do not contain the frequency data. The frequency data is compressed inside the app.asar file which contains the application. But unpacking does not help because afterwards the app won't run anymore. But just let me know what's missing and I can add the Austrian data and create another release. Its not a big deal. That way we have it in the official release as well. Apart from that I don't think that there is any difference compared to the regulation here in Germany. At least the usual microphone bands around 700, 800 MHz do contain the LTE Spektrum and those frequency bands are mostly the same worldwide. But as said, I will take a look at the link you sent and check if there is any difference and add it. If there is anything else missing, just let me know. |

Hi @berkon, I have sent you an email but didn't receive an answer, here is my question: For the moment I don't have time for supporting such project on GitHub. The current description of the APP is on the link: https://drive.google.com/drive/folders/1E63doe5HiAtov1AftVnC1UDjJjsgb0Y9?usp=sharing https://groups.io/g/tinysa/message/19481 Are you interested in supporting such a new project? br, |

Hi @moreben2023, thanks for your update. Unfortunately I'm currently very busy too and don't have the capacity to host your application. Sorry. Regards, |
This issue will be kept open forever. It is thought for all of you who can/want to contribute all sort of frequency related information. You don't need any programming skills at all. Just let me know what YOU know about specific regulations in your country or yet unknown vendors. In regards to the Wireless Microphone Analyzer this especially means:
Forbidden frequency ranges for certain countries
Frequency ranges which vendors use in their products (and are missing in the tool)
Recommended channel presets of vendors
