I use this on my main AM 80metre Transmitter:-

https://www.s9plus.com/FAT%20MAX.html

Its a nice little kit that sits between the mic and the mic input socket on the transmitter. It helps to limit the bandwidth of the transmission and can be varied between 4Khz and 10Khz. It can keep the trasmission to the recommended 6Khz limit for AM on 60 metres ( 5.317 Mhz ), not that I go on 60 at the moment. It does have some compression built in, which can also be varied.

Cheers

Aub
