VOA Radio Marti DRM 7345 kHz

Today's reception report.

Attachment 1: Longest audio period (1H 34m) not interrupted by a DReaM crash.

Attachment 2: End of received transmission(1H 08m).

Weird how the received signal strength (and consequently SNR) suddenly drops at 0027z from S9+10dB down to S6.

Today's reception report.

The (local) afternoon signal strengths were low (presumably the skip was going long) varying from S9 down to S6 and causing DReaM to crash many times during this time period.

Attachment 1: Longest audio period (0H 44m) not interrupted by a DReaM crash.

The signal levels picked up towards the latter part of the transmission before coming to an end.

Please note how the delay (brown line) has increased from afternoon to evening.

Attachment 2: End of received transmission(1H 36m).

Today's reception report.

Attachment 1: Longest audio period (1H 19m) not interrupted by a DReaM software crash.

Attachment 2: The last 44 minutes of transmission.

Interestingly the received signal strength, looking at the S meter, rose from an S9 level to S9+20dB just before dropping out at 0147z.

I also monitored the signal via the KPH KiwiSDR web receiver at Point Reyes, California and noted that the end of transmission was at 0208z.

Today's reception report.

I raised the remains of the wire antenna about 2M above the ground as a temporary improvement.

Attachment 1: Longest audio period (2H 26m) not interrupted by a DReaM crash.

Attachment 2: End of received transmission (1H 10m) at 0150z following the usual sudden drop of the signal - the transmission closed at approximately 0202z (I was monitoring a KiwiSDR web receiver at another location).

Today's reception report.

Using a sloping long wire as the antenna.

Attachment 1: Longest audio period (2H 11m) not interrupted by a DReaM crash.

The signal faded in and out later in the evening as the propagation changed.

This afternoon's reception report.

A short report due to thunderstorms and having to disconnect the antenna.

Happy Easter!
