Re: digital modes on 2m 70cm

Thanks Tony . I have done quite a bit of MS on 6 but nothing on 2M . I’ll try FT8

The most popular VHF modes are FT8 for terrestrial propagation and MSK144 for meteor scatter. You can get an idea what the activity is like by checking out PSK Reporter with the 2 meter filter on.

If you're used to 6 meters, you'll find that Sporadic-E and other long distance propagation modes typically happen less frequently on 2 meters and a lot less on 432 so it pays to get email alerts to let you know when the openings occur.

If you're looking for daily propagation on 2m and 70cm, aircraft scatter is the most consistent mode out to a few hundred miles. It's easily recognizable by the Doppler shifted signals which FT8 usually handles well.

I've attached a PSK Reporter screenshot that shows the distances you might see on 2 meter A/C scatter. The other screenshot will give you an idea what the A/C Doppler is like on 2 meters.

There are several amateur satellites that you can try as well.
