I have implemented such a trial scheme to look at DCF39, CFH, 136KHz, the TA slot and SXV. The intention is that my web pages should be updated around 0700utc each morning. There is also a bonus, since Laurie G3AQC puts a very good signal into this location there is a slot at 135915 to 135927Hz which is automatically plotted, so if you want to try out your transmitter feel free, the period between points plotted is 90s so any transmission must exceed this several times to be useful.
