Hi John
Most of the upper run of "dashes" have an interesting "hook" in the last 1/3 of the dash. Almost what my agricultural locals would call a "bill-hook".....quite consisent too unlike sporadic interference.

Markus,


Wonder what the little dash below Stefan's "F" was... possibly local QRM
from some MFSK PLC system? We sometimes seem to find a number of
unexplained scattered dashes on North American QRSS spectrograms.


I watched the entire band for a while this afternoon, and homed in on
the 136.552 kHz frequency range below, after seeing some "dash"
activity. Interesting.

John, W1TAG
