With all the QRM on 6925 lately (the longstanding pescadores on LSB, who are now using USB as well) I wonder if another frequency would have less interference? Also several operators tend to be a little on the low side, closer to 6924. That means that the pescadores even on the LSB appear in the passband.
There's 6930, but since 6933 LSB is commonly used by pescadores, that may not be a good choice.
There's often LINK-11 around 6947/6950.
6903 and 6913 are used by MARS.
6935 seems to be clear most of the time?
What do folks think?
