sri, Stefan, I didnt excercise patience in the receive = mode because I had to manage the TX antenna feeding problem.

now Im transmitting= on 8269,900Hz, so the 8270Hz is free for Markus (?)

PS I have to length= en the RX loop. seems the equipment as it is is deaf.

Hi VLF,

Hi Stefan,

thanks for the invitation. Three statio= ns simultaneusly on air would be cool, just like in the old days on 89= 70. My antenna is up, but today I'd rather make use of your strong carrier = to observe the diurnal variation. Looks like we've already entered the midd= ay minimum. Maybe I should set up another instance to observe the phas= e evolution as well.

There's also some directional variation i= n Todmorden: After 8 UT, your carrier is better at 90° azimuth but lack= ing at 130°.
