Hi,
Every few weeks there is someone in the WSPR facebook groups or support
forums looking for help because their callsign appears to be used by
someone else.
This is usually the result of a hash collision and it's pretty
cumbersome to fix, because we have to find and contact the original
transmitter.
I have noticed that many operators use type 2/3 transmissions, even
though they don't need to.
To put this in numbers:
I've analyzed 705547 spots that I received in the past 3 weeks.
58183 of them were type 2/3, from 280 callsigns.
Only 40 of them would have actually been needed to be type 2/3 (Using
composite callsigns or on mobile operation)
That means, 86% were standard and stationary callsigns where type 1
would have been sufficient.
My guess is that the operators either use type 2/3 by accident, or they
don't know that it's unnecessary (the wsprnet server remembers the full
6 character locator, even if type 1 is used).
The option to select type 1 or 2/3 is on the WSPR/FST4W main screen.
Would it perhaps be better to hide that option somewhere in the
pulldown/settings menu instead of the main screen, and add a warning or
check to it?
