Sorry,too many QSO modes as it is and most operating,(not saying you guys) are using WAY too much power and not following the band plans.
Each new QSO mode to me looks more like a bunch of seagulls swooping in to snatch up the french fries in the Mc Donalds parking lot and when they are all gone,they move to somewhere else to destroy.WSPR,especially 30m is being killed with JT65 users daily...right directly on top of the WSPR segment along with RTTY to boot.Then the occasional JT9 where some for whatever reason think 100w is a good idea.All you get is a splattering mess free for all almost "contest" like.
How many contacts does one need in an hour and how important is it? Not that important where you come and destroy it for the QRP folks.
This particular forum(I think) is about QRP,not QSO modes...or am I wrong here?
The original suggestion to this topic is using FT8 mode on the U3S QRP Labs kit.
Now if a QRP 100mw signal on a piece of magnet wire dipole is QRM? But negligent QSO mode operators running nutty power levels,towers,beams transmitting anywhere they want are the victims ? Something is wrong with the thinking here.
I been running 20mw JT9 beacon for over a year now occasionally getting stomped over by JT65/PSK31/Winlink/RTTY and the crazy part is I still copy them WITHOUT my antenna connected in my basement...the definition of QRM.
