Is that digital sounding chirping on the new 5MHz freqs the primaryuser?
 

Sometimes I hear a piccalo-rtty-ish digital signal on one or more of our new
5Mhz frequencies. Is that the primary user of these freqs trying to use
their
allocations and hams clogging the channel? Or is it from outside the USA?
The signal strength is weak, so maybe it is from region 1 or 3.

It isn't weak in the Midwest, in fact I've already wondered if hams are causing
interference to it since you can hear a few QSO's right along with it. May be
we'll hear about all that interference we're causing, maybe not. We probably
aren't interfering with the transfer of their data communications, but they
might not like hams talking over their digital transmissions.



Now that the novelity of the new band is wearing off, I think hams are
starting to avoid the
channels with the digital signals. As secondary users, we are supposed
to avoid interfering
with them, and accept any interference from them to us.
