Re: [Elecraft] PRE/ATT intermittent fault

2010-01-07 Thread DaveVK

After how many years?  I finally fixed the intermittent sensitivity issue I
had with my K2.  The problem was not a latching relay but a cap on the
bottom of the main board.  The legs of this cap protrude under the NB
option.  I noticed that one of the legs had not been soldered through the
hole properly.  

I was too busy and hurried to fix that I did not note the part number... but
anyway... this may help somebody else in the future.

Kind regards all...

 Occasionally I find the PRE/ATT fails to work.  Sometimes the PREamp

 I should have a replacement relay coming with my KPA upgrade - but I ask 
 could it be something else?
 
 This is only a problem on rare occasions, but when it happens it is 
 annoying.
 
 PS I've retouched the solder to rule out a dodgy connection to the relay.

[Elecraft] PRE/ATT intermittent fault

2007-03-21 Thread David Walker

Hi folks,

Occasionally I find the PRE/ATT fails to work.  Sometimes the PREamp 
works, sometimes it doesn't.  Sometimes the ATTinuator is louder than 
normal mode.


I should have a replacement relay coming with my KPA upgrade - but I ask 
could it be something else?
