All of these (Choke, RFC, L) are basically just coils. There is no

Well, I got the linear working OK, at least on digital modes which are 99% of
my QSOs.
I'm switching it on and off via the COM1 port and an opto-isolator. The
opto-isolator switches the base to collector connection (12K resistor in

hi,
i have the following problem with my elecraft K2 s/n 3922:
when i listening to a station in a quietly position of the AF GAIN (position 9
o clock pm), then the audio was a little bit distortet. when the AF GAIN are in
a louder position, may be 10 o clock position, the distortion on the
Typically, the extra bands can be a tolerance band of silver or gold. 10
per cent for silver and 5 per cent for gold. On resistors that have a
fourth color band, that sometimes is a voltage rating, if not a silver or
gold band.

Manfred,
Does this occur with both the headphones and the speaker? If it is only
with the speaker, you may have a speaker with a distorted frame.

Hi all,
I have made progress with making a touch paddle for my K2. I have some

I have never heard of a resistor with a 4th color band for voltage.
Using 4 color bands for the resistance value is quite common -- see
just about any small 1% resistor. Three bands for the significant
digits and one for the power of 10.

AMEN! I can't agree more with Mike! Why get sloppy and why some guys trying
to run their keyers at 40 WPM? Why send your callsign just once
on the initial call? Twice should be a matter of minimums,
how does the sender know his signal is BOOMING in or in the clear?
You just have to ask him
