>>Hi MF,
>>
>>A few days ago i took some RF litz wire and built a loop that is now 
>>hanging on the wall inside my home, just 1m besides the bed 
>>:-) (no XYL 
>>here spoiling the fun). The loop is beaming to about 150/330 deg.
>>
>>After playing some days on 160m (an unusual high frequency, 
>>witch feels 
>>very strange. And the band is full of unknown callsigns!!) i did now 
>>move down to more or less low frequencies, the 630m band!
>>
>>About 10 nF is needed to series resonate the loop. It has 
>>about 2m x 2m 
>>of size. The antenna current is not stable because the WIMA FKP-1 
>>capacitor becomes warm during the 2 minute WSPR sequence. But the 
>>maximum current in the loop is 14 A. That explains why the

>>tuned so that the upheating capacitor runs into the resonance 
>point in 
>>the middle of the WSPR sequence, then it runs out of the resonance by 
>>upheating further. It can cool down during the following quiet 
>>periods..
>>
>>14A into a 4 square meter loop at 475.7 kHz, how much ERP is 
>that? The 
>>PA consumes about 3.5 A at 13.8V, i.e. about 50 W.

>>The system will run over the weekend, even during daylight. 
>The signal 
>>generator is a Raspi which will have no internet connectivity

>>on, so let's hope the time offset stays inside the accepted range for 
>>this experiment.
>>
>>What will the best distance be? So far the band is closed but i'm
