OTOH, Mr. Rauch did turn out to be 'absolutely correct'. One can build a
silver conductor VHF parasitic suppressor for a 3-500Z that has a lower
VHF-Rp than a resistance-wire VHF suppressor. For instance, a 200nH Ls
and a 200 ohm Rs. The resultant Rp is only 60 ohms at 100MHz. This is
clearly better than the 101 ohms for the nichrome-60 resistance-wire
suppressor {Wes, N7WS} -- and it is way better than Mr. Rauch's
suppressor for the AL80B, which Wes measured at 166 ohms. . . However,
the trade-off with the clearly-superior admittedly-lovely
highly-conductive silver strap Ls, is that Rs is going to dissipate 43w
at 29MHz -- which is hardly good news for your typical 3W-rated MOF
resistor. - - Thus, the advantage of a resistance wire Ls is that it
reduces VHF-Rp - without increasing the dissipation burden on Rs. {Mr.
F. E. Handy wrote about resistance-wire VHF suppressors on page 72 of the
1926 *...Handbook*.}
The laugher is that Mr. Rauch probably realized this in in December,
1996. The rope began to unravel on 28 November, 1996 when Mr. Rauch
proposed that We add 5 ohms of ESR to Ls and perform some calculations.
However, he quickly cancelled his post, and he has stonewalled the
subject ever since. . . Ironically, when Wes measured a typical
nichrome resistance-wire Ls, the 200MHz ESR turned out be 4.99 ohms!
- So, where does one buy a a sub10nH 200 ohm resistor that can dissipate
45w? Not at Radio Shack (tm). Cesivid, Inc. [716 286 7610] can make
such resistors. Their rep told me that a minimum order would be 1000
pieces at roughly $11 each.

In a debate, if you aren't sure who won, it's a pretty sure bet that the
guy who fired off the most piss is the one who lost.
