[Elecraft] discussing dislikes and likes

Hi

There seems to be two marking methods used by capacitor manufacturers. One
is to simply put the value in pf like 47. The other method is like resistors
where the first two digits are the value and the third is the number of
zeros. So 470 is 47 and no 0's. A 470 pf
capacitor would have 471 on the capacitor or 47 and 1 zero. Unfortunately
there is not a standardization between the two methods. At least they have
dropped the nano farad marking that was popular a few years ago.

I keep a small 7 power magnifier on the bench at all times for reading
component values. I like the Hastings triplet type of magnifier because it
has no distortion at the outer edges of the viewing field as most other
simple magnifying glasses. Some people like the large magnifying lamps but
it does not work for me. Others use the OptiVisor stereo magnifier and like
them. You will find some form of magnifier is just about mandatory for
building kits.

if you don't like the looks of a mod don't do it but if you really won't to
complain about something try capacitors and their markings spent 4 hours
sorting caps and trying to match them to the list on page 49 the 47 pF cap
gave me the most problems as it is labeled 470 not 47 go figure and to top
it all off those markings on the chips are so hard to read if you don't have
a loop or magnifying glass forget it better off using a cap meter to measure
the caps but you have to have a good battery in the meter (arg went dead 2
hours into the sorting last night) well lets get the cap manufactures to do
a better job and get them all on the same page as to markings arg

okay now that I got that off my back I go back and melt some more solder.

p.s. I did find the elecraft cap chart this morning that helped me finish
the id thanks elecraft
