I can see the 7025 carrier, (spot on 7025) quite weak in Alberta. I can
also just detect the 120 hz sidebands, using the perseus and 0.48 rbw...
No stepped carrier seen in the vicinity.

The stepped carrier does not fade due to ionospheric modulation at the same
rate or period as the constant carrier. Are the two sourced from similar
locations? This implies not.

120 Hz, I can forgive due to a badly filtered power supply. However, the
stepped frequency, always upward, seems to always be there, but it's
presence is not fixed between time slots.

Hi Dave,
I just looked at that signal using an SDR receiver set to an RBW of 9.2
Hz and I don’t see much but possibly 120 Hz sidebands but they are at
least 50 dB down from the main carrier.

Does anyone else hear the discrete upward stepping to the additional
constant carrier?

There is more than one carrier. One stays put, the other steps
upward,
reinitializes, then begins again. Time: 1358 local, 2058 UT. There
is a
fair amount of weak non-amateur activity on 7.025 MHz.
Receiver: Icom 7300 Antenna: 450-foot long doublet fed with
balanced line, home
brew
bifilar common
mode choke, home bres
L-network.
I'm in the county with a relatively quiet RF environment.

Just noticed around 3pm EST a strong (S9) constant carrier on

that appears to be skywave. A very crude quick check with
portable
flag
indicates it’s heading is approximately 130 degrees from my QTH
near
Indianapolis.
Just FYI in case it continues for any length of time.
