[Elecraft] K3 construction problem

Since Garry suggested I ask the reflector I am posting the following 
that we have been trying to figure out on my K3 kit. Any help would be 
appreciated

I have visually checked all of the pins and/or reinserted them

EVERYTHING has been done with an ESD wrist strap attached to the radio 
and on an ESD surface. I dont see anything broken or missing

No increase with the preamp. No increase in noise when the antenna is 
connected.

No increase in the noise

Re: [Elecraft] Desoldering tools

2005-09-29 Thread Dennis Wieck



to imply that they may make knock-offs of Hakko products as their 
soldering

stations appear virtually identical to those from Hakko (the 936-x models
specifically).

While the case appears to be identical to that of the Hakko, so do the
desoldering tips, the 'power supply' is something new. It appears to be a
'wall-wart' type of supply, but may be nothing more than a transformer
which allows the 120VAC unit to be used on 230V as well... Uhh... scratch
the last... you may have your choice of voltage ranges, but not both...

The specs seem to indicate that it is switchable between the two 
voltages.

Additionally, the AOYUE seems to offer a number of additional tips can
accessories which would have been extra cost items from Hakko.

For the price, about $100 less that the Hakko price, it MIGHT be a good
buy. But caveat emptor...


These look like the stations and desoldering equipment sold by Circuit 
Specialists under their brand name.
