[Kenwood] Kenwood D700 noise on ALL units?

[Al - NW2M]

Greetings,

I came across a strange noise on my new Kenwood D700.  I have confirmed
this noise on several D700s and suspect your rig may experience it
too.   The problem is a strong 5,000 Hz tone being transmitted on VFO
B.  My new (Dayton 2002) D700 has this problem along with other D700s
over a year old.

Here is the setup:

VFO-A - Blank, not used.
VFO-B - 146.520 for VHF or 446.000 on UHF.  Makes no difference.
Another radio tuned to listen to your transmitted signal.

The first key-up on VFO-B is OK.  The second, and every key-up
thereafter, will have a loud 5K ring to it.  It decays over a 1/2 second
period, but is still present on the transmitted signal.  A 5K tone is
very noticeable!

The problem is seen when ONLY using VFO-B.  Since most D700 users have
both VFOs populated, the problem is never seen/heard.

I have seen this on every D700 I have tested.  Their owners were very
surprised!  Just a nit on a great rig.

PS:  Dayton had them for $535.  Anyone find them cheaper???
