That is a soft silver solder, then? A hard silver solder (which is what is
meant by the generic term 'silver solder' generally) would have to be
reasonably red at around 620 deg C for it to melt. Soldering that takes a bit
more than your old 'American Beauty' iron!!! (Shades of a 1948 W6ISQ article,
where his 'American Beauty' iron was described as getting 'so hot that solder
applied to the tip instantly vaporizes'!)
>The Low-Q suppressors we purvey have a Q of c. 1.5 at 100MHz.<
What is the effecive parallel impedance of them at 100MHz? That's what will
determine VHF gain.
