Hi Gerald,

I have nothing against phone based SDR, my point was not to ban GPS from
receivers, but add new category for those who wants to run with mobile
based SDR receivers.

I even built one for myself from RTL based TV dongle ($12 from Internet)
and free SDR software for Android  - it works.

I see potential for this and I agree with you.

What I disagree with - Charles wants to ban GPS from radio receivers(not
mobiles).

73!

Vadim
