I called CQ on CW down in the Extra segment of 15 meters and PP5AX in Brazil came back unexpectedly. The band was totally dead and I was making antenna measurements interrupted with the occasional CQ for grins. I thought, maybe calling CQ up on 21.430 MHz might have the same results, so I have been calling CQ AM throughout the day. Would be great fun if I saw something on the panadapter pop up thru the noise floor. I'll keep trying ... perhaps in between the BBQ and baseball games we could connect.

Trans-equatorial propagation on 15 and 10 meters is very common during late summer and fall.
DX Maps shown below is always a good indication of band activity.
The screen capture shown below was taken at roughly 7:40 PM EDT today 9/5/21

Nothing heard ... it does give me the opportunity to try out different microphones and widen out to 16 kHz.

Wouldn't surprise me though, if a non-AM'er came back and said I was too wide!

Dead band and all ...

Maybe you're listening at the wrong time or maybe your antenna fell down  Grin
Screen shot below shows lots of activity around 2:30 PM EDT today.

Yes, I see lots of activity on FT8 but I am philosophically opposed to operating that mode.

CW and AM ... Deadsville

Hexbeam still hexing ....

I also checked DX Summit and it showed lots of CW activity and some SSB activity on 15 meters. I excluded the Digital modes.
http://www.dxsummit.fi/#/?include=21MHz&exclude_modes=DIGI
Since this is a rolling list, it gets updated in real time

But no AM listings. I guess AM is dead! Haven't made an AM contact on 15 or 10 meters in several years but haven't pushed my activity there either.

15-meters is on!

The band finally opened up and AM is alive and well on 21.430 Mhz.

Had an hour long conversation with Guy, WD5ACP and then K6LPM breaking in.

I saw the W1AW code bulletin signal far larger than usual and the FT8 morass peaking S9+10 and rightly figured someone might see the strange signal at the end of band and come investigating. That is exactly what happened. I always seem to be someones 'first AM' contact!

17-meters was also open with Japanese stations pounding in. However, I think I would get run out of Dodge if I showed up slinging AM about.

Too early to tell how the band will be today .. hopeful.
