ACC2

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?

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 custom KXPA100 interface cable, the ACC2 keyline signal is routed to the amp, and the GPIO signal is broken out to its own connector for your use.

That menu item refers to the GPIB half of the ACC2 jack - since it has
multiple selections, the default should be OFF.
I believe the KEYOUT part of the ACC2 jack is always active - although I
have not checked it myself.
Note that PTT is an input to the KX3 and is *not* the same as KEYOUT
which is an output.

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.

Re: ACC2

I need to clarify some of my misconceptions about ACC2 and offer some unfortunate experience with the special cable package offered with the KXPA100 when integrating to the KX3.

First off the GPIO function has nothing to do with interface to the amp. Perhaps that is why there is no reference to GPIO in the amp manual.

About a month ago I bought a KXPA100 and the special KX3 interface cable kit.

After it was hooked up to the KX3, I could not turn on the amp with a PA = ON.

The problem was a bad cable. Cable badness was verified with the discovery of an unsoldered wire in the little black box that hides all the interconnects.

A new cable set was requested, arrived promptly, and solved the problem.

A week later the amp refused to work properly. If I set the KX3 to tune and advanced the power past 10 watts both amp and KX3 turned themselves off. Obviously a power supply problem?

I tried a different power supply that was tested and known to be good but I still had the problem. Turn the power past 10 watts and the radios turned themselves off.

That is when it occured to me that maybe setting ACC2 = ON might be needed. Of course that was wrong. By the way you should change that from ACC2 = ON/OFF to GPIO = ON/OFF. Evidently the ACC2 keying line is alwas on.

This morning I replaced the short modular cable connecting the amp to the black connection hub on the special cable. Everything is working as it should now.

I really like the KX3 and the pricey KXPA100. I can't say the same for the cable set.

You might consider testing these special cable sets before shipping them.

Re: ACC2

Frank,

I'm sorry to hear that the cables had to be replaced. This is very unusual. We have them custom made and they're supposed to be 100% tested. I'll get this feedback to our manufacturing supervisor.

Wayne,

Thanks. Your radio products are too good in quality and performance to get undeserved black eyes from faulty cable sets.

Could very well have been a one-off.
