I am currently running a DFCW-60 beacon on 476.181 kHz, using the same 10m^2 indoor transmit loop as previously on LF. With 35 Watts of RF input, estimated radiated power is around 2 mW, with lobes p

very interesting for WSPR tests ! few questions: - mono-turn or multi-turn ?? - what are you using for match to TX ??? many thanks and 73 de Mauro IK1WVQ The daytime groundwave signal is visible in t

Hi Mauro, this is a single turn loop, around 3.5 m wide and 3 m high, now consisting of the braid of a piece of RG-216 coax cable. Required capacitance for 475 kHz is 7.1 nF, made from five 33nF FKP

Hello Markus, Thanks. This is helpful for many people trying to improve their RX equipment. A QRPP beacon! Don't we have a nice hobby?!! :-) 73! Stefan PS: Tomorrow ordering parts for a stereo MF RX!

Hi Domenico, no, not me. The strong signal in https://dl.dropboxusercontent.com/sh/qx230q4lxerepeo/AAD7lpktx1thN2B5rIggKW52a/argo0034.jpg is probably IQ2MI from Milano sending QRSS-3. To help save th

Hi Markus, very nice experiment! I did something similar some time ago: http://people.physics.anu.edu.au/~dxt103/472/small_loop/ I would like now to make a larger loop using a 20m thick coaxial cable

Hi Markus, Thanks for your DFCW-30 transmission. I can see you clearly in daytime on my RX in the city! However i can't see you on my RX is the garden! The remote system seems to run stable now, at l

Hi Stefan, good to see the remote station working nicely now. ...yes you do ;-) There is a slight frequency offset in the remote grabber which had put me out of your QRSS-30 band. I now switched to m

Hi Markus, Really? Wonderful! :-) And the stream is still running. I'll watch it some days now to see if all Raspi problems are gone, then the next part-project is the RX. Meanwhilethe sky wave is pr
