Those of you that have not picked up, or had a look at the new ARRL =
Handbook 2000, there is some mention now of Nichrome Parasitic =
suppressors. It reads as follows in chapter 13.26.
"Some designers use nichrome or other resistance wire for L2, but there =
is no credible evidence of any fundamental difference in importance as a =
result." It goes on to say that W4ETO, amplifier manufacturer has never =
seen an HF amplifier using modern tubes that could not be made =
completely free of VHF parasitics by using one of the simple parasitic =
suppressor contruction described above" It does not mention what =
"advanced" techniques should be used!
Anyway for those curious have a read.
