"Not in use" - usually used on Reserve frequency as a sign that the frequency is not used today and is going to be shut down after enough time has passed playing the message

"Jam" - when we have jamming issues usually 5Mhz AM is replaced by 10Mhz AM reserve, while 5Mhz and other transmitters are dealing with the jamming issues. The sounds below are the ones used aswell

When station "Altyn" has those difficulties different audio is played.

History

When "Altyn" didnt even had a name "Mukhash" was searching for a frequency. First thing he saw was 5 Mhz because it was not used at all.

However this would bring issues later.

When he launched 5 Mhz he also searched for a second main frequency, this is when 10 Mhz came to his mind.

And then 10 Mhz also became a main frequency. But then people noticed that the transmitters were constantly overheating. And so he decided that it was time to shut down 10 Mhz temporarily

The overheating issue was being worked on, while "Mukhash" had already decided to start the FM (WFM) broadcast on 101 Mhz.

Then "AAA" came to jam 5 Mhz and the neighbouring station 5.1 Mhz.

Once they found "AAA" ip he became unusually quiet

There were other jammers aswell

Later he fixed the overheating issue with 5 Mhz but forgot about 10 Mhz, once he remembered he decided to make it reserve

After some time he managed to make the 5Mhz even higher quality and even stronger.

But then appereantly other user was taking 2.5 Mhz, 5 Mhz, 10 Mhz for WWV relay, and he served a notice that once we go off for a break he will take over the frequency, however this lead to a massive jamming drama

Then we solved the issue temporarily with Altyn going into LSB programm

The guy abandoned the frequency again and Altyn was set back to AM

Then Mukhash figured out how to do DVB-S2 television and now the AM / FM frequencies are sometimes defunct in favor of DVB-S2 TV

The history is still going!!!
