[VHFcontesting] FT4 Mode

[Mark Spencer]

It is interesting to me that the new JT modes seem to be emphasizing speed.   From my perspective I view the digital modes as a means of completing qso's that can't be done with traditional analog modes and am happy to trade off speed for better weak signal performance.   Or I like really fast modes that can exploit brief propagation modes such as meteor scatter outside of a major meteor shower.

That being said the activity levels where I live are low enough that if I manage to work more than 10 stations while activating a rare grid in VE7 land I consider the trip to be a great success (:   So my perspective may be a bit unusual (:

I'll be curious to see how this new mode works out in practice.  I appreciate the efforts of the developers and early adopters / testers.

  In the mean time I am expecting to use JT9 on 50 MHz this season.
