arrl 2005 handbook p.2.8上这样写着:
awards for vhf and uhf operations may also require the grid locator (or
“grid square”) in which your station is located. current practice is to include
your 6-digit grid square on your qsl card even if you have no plans to
operate vhf and uhf, since some hf competitions and awards require your
grid square designator.
如果觉着有用,
当然可以写上。
我只说没必要。
各人自己看着办吧。
