[CQ-Contest] Filters

[Mario, S56A]

W0UN: And at no time did any capacitors fail the 200 watt test -- or even 
get very warm.

I guess you were lucky!  I made W3NQN filters with a big VU mica caps for 2 
kV and they all failed on 7 MHz and above.
Manufacturer sent us new batch for free but they are not tested yet.  DL2NBU 
specifies VAR power ratings required.

Simple ICE filter configuration should survive most abuses but 21/28 MHz 
isolation is not good enough for SO2R.

Please note that BPF info is available in ON4UN book on low bands.
