Hi all,

A weak signal in a noisy environment with a chaotic IR gave the attached result.


EDIT: A new thread has been opened for this test, please move the post there.
Thanks.

A bit chaotic Impulse Response on 3995 kHz this morning, but a very good result anyway. According to the schedule above, the entire transmission came from Sines. However, there was a break at 06 UTC and after the break the SNR seemed a little bit lower that during the first hour.

New Label: "BBC & DW Test"

BBC & DW Test on a new (?) frequency - 9610 kHz. Nearly perfect decoding on a clear channel. The log is 50 minutes long.

Hi all.

Perfect clear cannel and very strong signal stringth up to 74dbuV but little instabile propagation . CDA was 99.36% ok. MODE A is very good to my location if Ionospheric layers is ok.

Log is 108min.

BBC & DW Test on 9545 kHz. Perfect reception for 60 minutes here. My National RF-B60 does not provide such a high SNR as the FRG-7700 does, but it works fine anyway.

The second log is taken with the FRG-7700. The log is 70 minutes long and perfect.

Prpoagtion very up and down from Wofferton and so start CRI on 9540 10db over DRM not so fan , listen to dropout.
Log 68min CDA 92% for CRI .

Just two clipboards here from DWT. Woofferton is good but Sines more stable as always. As seen in Sixtens log, reception of 9545kHz had some detoriation here too, about 12UTC, but Sines has remained 100% stable.

It will be interesting to see the results of the DW/BBC cooperation.

Anyway, it seems that Journaline is going to be lost.

Interesting to see the new label this morning, similar results as usual as transmission parameters were basically the same as before.

Sorry, just a short log for the new 9545 kHz with bad results.

Not too bad just using the DWT/whip antenna, no problems using mode A.

Some problems after the switching at 0600 (not sure if the second hour was from Sines as scheduled?)
