[NLRS] 3400 vs 3456 MHz

[Arliss]

Three years ago the ARRL recommended that terrestrial users of 
3456 MHz move to 3400 MHz as time and resources permitted, and I 
know that most EME operation on that band is around 3400 MHz. 
However, I am wondering if there has been any move in this region 
to 3400 MHz. In other words, if I buy a transverter for 9 cm, 
should it be set up for 3400 or 3456 MHz?

Thanks & 73,
