KXV3A

[Bob Henderson-2]

Could someone please point me to schematics for the KXV3A or otherwise help
with identification of a component?

KXV3 schematics are bundled with those for the K3 but I have been unable to
find any updated to KXV3A.

My KXV3A has suffered a failure due to high level RF while on receive.  The
burnt out component appears to be D5, located between L1 & L2.  None of
these components are shown in the KXV3 schematic.  I am particularly
interested to learn the part number of D5.

Assistance appreciated.

Many thanks.

GM Bob,
The schematics dated June 2010 have the KXV3A.
D5 is a BAP64-04. Looks like it is being used as a switch controlled by
the 7T voltage,
I can email you the schematics if you wish (7 MB).
Cheers and 73,

Many thanks Fred.  I believed I had the most recent schematics but I was
mistaken.  I have now downloaded an update.  I was guessing it was a 64-05.
It's as well I asked.  Rather a pity though, as Farnell hold the -05
butnot the -04.  I do some more digging to see if I can identify an EU
source.
