Bandspots for M17
This is a topic that I have recently taken over, but am not yet entirely familiar with. I am therefore forwarding you this information without any guarantee to its accuracy:
The result is that we now suggest the following frequencies for M17:
2m band: 144.875 MHz
70cm band: 433.475 MHz
