Note that "low self-discharge" or "precharged" batteries are a must.
You can get higher capacity batteries, but they'll always be dead when
you reach for the rig.

First, and most important, don't leave alkaline cells in your radio for long
periods. They will eventually leak. If you have the KXBC3 installed, I
suggest high quality Low Self Discharge (LSD) NiMh cells such as Eneloops, If
you don't have the KXBC3 installed, non-rechargeable Lithium cells
With todays microelectronics, false powering can occur with little current,
perhaps a milliamp or less, definitely less than that required to drive the LED
of an optoisolator. Voltage levels required are quite low, depending on the
design. As low as 2 volts can do the trick, and at that level th

Although a bit expensive, AA size Non-rechargable lithium batteries will
give longer life.
Rechargeable Ni-MH batteries will also last a longer time. If you do
not have the internal charger, you will have to remove them for
charging, so carry a 2nd set of fully charged batteries.

I have just put my KX-3 into portable service trying to locate noise sources
around my property and neighborhood. I put eight brand new Duracell alkaline
cells into the KX-3 and turned off the backlight. Preamp is set to 20 db gain
and I am using headphones with a homemade 26 inch loop for DF.
I own the K-Line and I’m awaiting my turn for a new KPA1500. I just purchased a
new HAMPLUS AS-603A antenna switch. It handles 6 antennas and 3 rigs. Would

antenna tuner for max power (big brother to the KAT500). With memo
There is a big problem with this, one that was unusual when Yaesu first created
this setup, but very common now. The issue is that of false powering of
receiving devices. In this day of low power micro controllers and other digital
devices, the device can actually be powered through the I/O port
The KPA1500 will just be listening. There will be
no issue with the +6V from the TS-990 true RS232
being heard by the KPA-1500 and PC, however I am
concerned that the -6V from the true RS232 might
get clamped close to 0V by the KPA-1500 input and
so screw up communications between the TS-990 a
Paul,
It is possible that short runs of "RS-232" can operate on TTL levels.
There certainly is no problem at the 5 volt level, that is entirely
within the range of the + level valid RS-232 signals.
The possible problem is with the low level. A proper RS-232 receiver
should ignore levels betw

does not have the second receiver. I'm sure the manual tells how to set it up
but I can not find it. This is a early radio but I sure do li

Well that was interesting.

The point is that the devices don't work together because the third
party manufacturers did not bother to understand the Yaesu design
and take the necessary steps to be compatible. Yaesu's only purpose
was to provide band switching data from the
