Hi Wolf,

Yes i tried to buy one from WIMA so i sent them a request. It was a 14V=20
/ 420 F / 900A type (SCMCA3B420MC00MV00 at=20
http://www.wima.com/DE/supercap_mc_block.htm). I intended to switch it=20
in parallel to my old battery in my car since i was nerved to replace it=20
each few years. Also i just wanted to play with it. But the price, even=20
including a discount of 30% for the university was very close to 1000 EUR=
!
But its quite a fascinating technic and i hope they will become cheeper=20
in the next few years. That is the perfect energy storage! Leight=20
weight, low volume, low internal resistance, lifetime 500,000=20
charge/discharges. Also interesting for the HF friends to drive a PA=20
when beeing /p or /m for calling the own callsign in a pile up, taking 5=20
kA current consumption :-)

73, Stefan

Hi Stefan,<br>
  <br>
Yes, 3000 Faraday sounds reasonable. But the price may not.<br>
Guess this is the type of capacitor used in 'batteries' to start large
Diesel engines in trains (no kidding).<br>

Hello Markus and group,<br>
      <br>
I will certainly look out for the signal. Only have to modify the
soundcard's input coupling capacitor a tiny bit, guess I must connect a
second capacitor in parallel. But sure there is something suitable in
the junk-box. <br>
