Updated docs - K3-to-Yaesu_Quadra_Inter-wiring

[Tom Hammond-2]

I have just updated some of the information for the documentation of my
K3-to-Quadra Inter-wiring which is on my web site.

Mainly, the updates were to WARN potential users of the info about the
'GOTCHA' with regard to using the appropriate 8-pin DIN plug required
by the Quadra's BAND DATA 1 connector.

The Quadra REQUIRES that you use a 262-degree pin pattern 8-pin DIN plug
at this location, rather than the more commonly available 270-degree pin
pattern plug.

The 262-degree DIN plug is commonly referred to as a 'horseshoe pattern'
plug, but it is NOT always stocked by many electronics houses.

If you attempt to use a 270-degree pattern plug in the 262-degree pattern
socket, you will likely break the socket!!!

Anyone who has downloaded previous versions of these docs, might want to
update to the latest version.  And, as available, I will try to (eventually)
provide a source listing for the connectors required for this interface
cable.  At present, I can find all of the connectors BUT the 262-degree
plug, and I'm still looking for a source for that connector.  Once I find a
source, I will add that info to the docs.

IF YOU KNOW OF A RELIABLE SOURCE FOR THE 2620-DEGREE 8-PIN DIN PLUG, PLEASE
DROP ME A NOTE WITH THE INFO.

Revised docs are available at:

The correct connector - DIN8/262 used to be available from DigiKey.
It was the CUI SD-81.  Here's a comparison of the "standard" DIN8
and the DIN8/262:

   DIN8/270:  http://www.cui.com/pdffiles/SD-80.pdf
   DIN8/262:  http://www.cui.com/pdffiles/SD-81.pdf 

CUI still lists the SD-81 but it is no longer shown in inventory
at DigiKey.  

Universal Radio in Columbus, OH (www.universal-radio.com) still
shows the "Kenwood DIN 8" for $5.99 (not exactly a "good" price)
and other Yaesu dealers should have it in their service department
(if they still have service departments).  The RF Connection also
lists the DIN8/262 for $1.00 but there have been many complaints
about the quality because the insulation appears to melt before
the solder does <G>.
