[Elecraft] K2 - 20m receive

[David Douglass]

Hi All,

=20

I=92ve have a suspect issue with low RX on 20m.

=20

The level of background noise on 20m is substantially lower than other
bands, and in general the RX level on 20 seems down to other bands.

=20

I=92ve suspected this of being the case for a while but just noticed =
more over
this weekend in the BERU contest.

I can still receive stations, and local VK and ZL still give strong =
signals
(s9 plus), but I have a feeling something is amiss. The receive level on =
20
is comparable with other bands with the pre-amp turned off (and before =
you
ask, I have the pre-amp on).

=20

I have full power out (on K2 and K2/100) on 20 and therefore think that =
I
have the alignment pretty much OK.

=20

Is there any parts in the 20m RX path that I should suspect that are
specific to receive on this band, and not shared with TX or neighboring
bands?

=20

I plan to do a full RX and TX alignment, once I have a good nights =
sleep,
but thought I would check here first !!

=20

Thanks
