Re: LF: Power experiment / Mini Whip / 8970 Hz !

["PA1SDB, Peter" <pa1sdb@amsat.org>]

Hello Lubos,

In the short time that I join the groupe here, I did not read about that discussion about powering the Mini Whip.

But now I know :-)  In the garage is is since this afternoon a motor battary already at the charger.

I will try to use such a accu / batery to.

 

Tnx for info !

Hello Peter!

I use a small Pb accumulator 12V/10Ah. There is enough energy for one week of receiving in it.
