Explanation but not one that makes, sense. At least it is being forwarded to technical staff:
"Hi Dean,
Thanks for sending this message.
We can't say for sure how you are able to pick up the Spanish broadcast on 9780 - our frequency for Western Europe is 9770 for our one-hour broadcast starting at 06.00 local time, so this could be an explanation. You could try to tune in to this frequency at the specified time to see if you can pick-up our English-language programme.
At any rate, we are grateful for this piece of information. We usually relay any technical feedback from our listeners to our technical staff who monitor the frequencies, so let us know if you notice any changes in the future.
All the best,
The English Service, RRI
