[600MRG] Capacitors

[Brian, WA1ZMS]

I have used Vishay 715P caps for my LPFs. No issues based on a small sample of filters up to 200w carrier and 500w PEP.

When I get back into town next week, I'd be glad to measure the Q of a couple of them on the HP test-set.  Let me know.

C values in the range of 0.0047 to 0.1 uF are required for most of these filters. All of the capacitors I have on hand in this value range seem to be extremely low Q, very high ESR.
