Re: New MGM Modes on Beacons

Andy G4JNT

JT4 is still in the latest (a couple of days ago) 2.4.0 RC3 version.   It had better remain, as it's in quite widespread use on microwave beacons, being one of teh few modes capable of coping with really widespread scattering such as that from rainscatter on 10 and 24GHz

When I asked Joe about it a while back, he assured me that JT4 and JT65 would be kept for this purpose.   Beacon modulations can't be changed on the whim.
