Several QRO stations using extremely excessive power were heard on the previous pass of AO-7 causing it to flip to mode A. God bless AMSAT-UK for launching UKube-1 which allowed me to still give out the ultra-rare grid line DO92/93 to many stations as CG6NJH. 

If you're running more than 5W, you're probably doing it wrong, 73
