Hi LF, This night i'm again running some DFCW-90 on 136.172 kHz. I saw that DCF39 is quite strong in YV, so maybe it is worth a try :-) 73, Stefan

R, FB! OK, try 136.5 kHz CW. I will run a beacon for a while. But there is terrible QRN here, i can hardly imagine that you can hear me. But we will see... I'm starting in a few minutes... 73, Am 15.

R Joe, thanks. Now, what is your setup on VLF? Are you using a 100m wire which you are using for LF/MF as well? What is the effective height and what is the antenna current? How do you couple the TX

R, Iban, thanks for the test. The beauty of LF! On that distance, it obviously works better than on MF although the radiation resistance of the antenna is just about 8% relative to MF... 73, Stefan A
