Of course it should be 23h 28min 0 sec. The transmission of the 4th was unintentionally interrupted, as explained in one of my previous mails. I'll do some minor optimisations on the coil now and will be back again soon. There is more than one request BTW. So i will run a carrier on 5170.001250 Hz then. 73, Stefan Am 06.01.2017 10:48, schrieb Markus Vester: > Hi Stefan, Paul, > > so that makes a fine record of 5.17 kHz successes between the two of > you!
