Frank,
ACC2 has two outputs: a keyline for the amp (always on), and a general-purpose
programmable output (GPIO). The latter is what's controlled by the ACC2 IO menu
entry. You can use this signal for various functions as described in the ACC2
IO menu entry.
When the amp is used with our cust
I knew there was something I did not understand about that.
That also explains why I had do an ACC2 = ON to make the KX3 work with the
KXPA100.

As an update, the KAT500 is headed back to the mother ship for a check up. All
indications now are that the problem lies internal to the tuner.Thanks to
everyone who provided input. Your help was very much appreciated. 73,

I suggest adding a second resistor, across the headphones' cord, forming a
pad instead of just a series resistor. Approximately 50 ohms shunt will
restore damping effect to the headphones' response. This is good practice.

I have the K3, KPA500 and KAT500 setup per Figure 1 on page 5 of the owner's

When I try to tune with the KPA500 in Operate, I get a fault on the KAT500.

That menu item refers to the GPIB half of the ACC2 jack - since it has

ACC2 = OFF appears to be a factory default. Why?
Other rigs do not disable the amp keying line. Why was it neccessary to do
that in the KX3?

Ok, got it working. I have two KSNY3 boards on main and SUB receivers. The

I noticed today, that the SVGA display shows one S unit lower than the

An example is as follows:

2. SVGA shows plus/minus 100 KHz, as the P3 does.
3. I turn on peak hold.
4. I have a peak of S9 on the P3, but on the SVGA the peak is

Not sure what the first paragraph has to do with filter selection on the K3?
Using the 1st IF output one bypasses all filters and the DSP 2nd IF

That has to be a K1 that you are dealing with, although you did not

When BAT is selected, the MCU samples the voltage produced by the R6 and

to a low state which turns on the LED.

If there is no receive capability at all on the radio it could be quite a
serious fault - either with the radio or the feeder or aerial.
I'd suggest that under these circumstances trying to transmit is a daft
idea. Rigs these days are pretty well protected, but not completely
foolproof.
