T writes: "This morning V24 transmitted in a time slot I have not seen before, and as far as I know has not been seen or reported before. All other V24<br />
transmissions today were as expected.<br />
From 1630 to 1637:37 on 6730 kHz there was a 5f transmission of V24. The music was a song heard in many other time slots. The carrier for this transmission<br />
came up at 1622 and left the air about 30 seconds after the last audio. Except for the audio start time of 1630 it was a very typical V24 signal.<br />
Prior to this the latest V24 transmission I know of started at 1620. The 1620 time slot is populated about 6 to 8 times a month and I expected it to be active<br />
today on this very frequency.<br />
It is possible, naturally, that this was simply an error and the signal started late but was intended to start at 1620. However, in the few past transmissions<br />
with errors in start time the audio has started as soon as the late carrier came up. The fact that the carrier was up for just under 8 minutes before the audio<br />
started would seem to indicate there was nothing hurried about getting this signal on the air."<br />

Problems with sendings<br />
The XPA transmission on Wednesday 14/04 suffered with some problems on start up throughout its sending. The worst was seen during the 10118kHz 0600z<br />
transmission which resulted in a restart, as can be seen below:<br />
Further problems were seen on the 0620z 19/04 sending where the ID section of the message ‘111 111 111 1’ lasted for 60s instead of the usual 4s<br />
Above we see the repetitive nature of the pulses and overleaf the ID part in the message:
