Signal gets in here, but no audio :-(
(or lets say: a little bit of rumbling noise; problems with audio feed?)

More later.

Angry HCJB reception

South America in my World Traveller! But too weak signal for constant reception.



More later (of course)

Edit: A strong AM station has "joined" HCJB now.

78% audio since 0800 UTC.

It might be the first low-German program on DRM!

@DRMDAB: You are probably right with the first transmission in low german

Here's my log from this (first) morning. Not that bad with much QRM from 9865kHz.

Note: The first zwo peaks (04.10 UTC and 04.25 UTC) are not from hcjb!I tried to get DW after some minutes of quiteness at 9870 to assure that my web-controlled receiver works properly. It seems like Dream did not recognized that.
The HCJB Signal rises arround 4.30UTC (about 1 hour after sunrise?!).

Some of the dropouts (most in the last half hour) are caused by (about all 10 minutes recurring and through all am-bands) local noise which is arround at the whole neighbourhood. If i only knew what causes that?!?

To add to my first entry, here is the log from Switzerland. Unfortunately, there were three TX breaks at 0615, 0619 and around 0626 UTC, otherwise the last 28 minutes were perfect. I added Pifo in the log list, my distance to the TX should be OK.

PS: Even Morphy enjoyed receiving DX signals from overseas...

News from Ecuador

I wrote to Iris Rauscher (German service) about the reception conditions this morning. She just answered my message and said it might be possible to go up 5 kHz.

But I think you know more, Doug?

They have got a very nice QSL card (train) for DRM reports: drm @ hcjb.org.ec
Or to the German service: german @ hcjb.org.ec

Have a nice evening

Thumbs up

Looks even better in the last 30 minutes than on 9870 khz. But why use Mode C with only 9kbps? Audio sounds terrible. I think that at least Mode B with 14.5 kbps and SBR
should work fine. But it is really amazing how good an intercontinental connection with only 4KW works if the frequency is clear.
