Hi MF Not an option. PA mosfet left this cruel world last night :( Untill replacement will be running 500mW to antenna WSPR and Opera every 12 minutes 73 de Luis EA5DOM
Hi MF Seems like conditions were good last night I'm running QRP 105mW to antenna this days. Normally spotted up to 1500Km and sometimes up to 1800Km (SV8CS and DG3LV). But last night I got a spot fr

Hi MF PA is fixed now and current protection added. Running nominal 5A@12V at the moment Getting WSPR spots from DL in daylight The mosfet was intact ! That explained why it was not showing short cir
Hi Stefan, MF Not really :-) I use a couple of relais to bypass the PA and make QRP tests. Thrystor cuts this relais to bypass mode So PA and power supply keep on but without driving. After power off

Hi LF My progress to get access to LF: Added a coil on top of the 300mm pipe. With this in series can reach resonance at 270KHz https://dl.dropboxusercontent.com/u/7162072/Fotos%20varias/MF/IMG_20160
Hi Dave, Stefan, LF ! :-) Well, the big coil (double layer) is wound in the right sense, as CCW. Just as the other coils But unfortunately it is wound top to bottom, and the coils in the pipe are wou
Hi Stefan Unfortunately, even with bucket facing sky ..... rain will not be a problem here ! Hardly 95 litres per square meter collected since january 1st. And only thanks to rain during last week I
Hi Stefan Yet another convincing argument: As isolated coil, it can be covered with a bigger buck to get a step into VLF ;-) 73 de Luis EA5DOM De: [email protected] [mailto:owner-rsg

Hi LF Thank you Stefan Unfortunately there is no other Tx activity on LF from EA. And have no info about this being done before Yes, I'm in IM98WN. But need to fix many things before getting more pow
Ooops !! VLF This is getting too fast, isn't it ? ;-) Living in a 26th floor, my main enemy and at the same time my best friend is the elevator :-))) The motor variators using three plase 380V are ve

Hi LF Thank you all ! This band is amazing :-) Great dynamic reports Markus. You are now my ODX at 1500 Km ! mW TX power? Well, I know it is HARD TO BELIEVE, but that's it. Absolutely. U3 (old, not S
Hi Stephan Thank you very much for sharing you expertise on Yougurt manufacturing techniques ;-) The pictures help a lot to get a clear idea of the coil. From earlier descriptions read here I had a d

Hi Markus, LF This morning I have interrumped transmissions to measure power and the inductance of coils That causes the GPS recalibration process to work harder. First corrections are too low and tw
