No problem overhere. Migh be your plug is not activating the disable
contact in the socket. What happens if you plug in your headphones into the
front socket? Does that disable the internal speaker correctly?

Hurray for LOW TECH! I 'wiggled the wires' and everything is working again. I
pushed on the chain of AUX cables connections to make sure they were all
seated in their sockets, and low and behold the amp is back to working
normally. I still don't understand how the INHIB IN setting works, but

Hi all
Switched on my KX3 this morning, the LEDs. lit up and stayed on but nothing
else. Had to removed the batteries to clear the LEDs. Tried the external PSU
with and without the batteries installed with same result. Anyone any ideas?

And another warning: Nearby (like next door) lightning will be picked up by
ANY long wires which end up acting as antennas.
I did computer repair in Florida. I had a time share/multitasking system in a
law office that had thousands of dollars in damage after the building next door
got hit.
This sounds like good advice. However, every connector socket on my K3
is populated, ditto the computer, ditto the KPA500, ditto the KAT500.
Pulling all wires when there is a potential storm threat is totally
impractical. Even if I did, I'm sure some of the connectors would
simply not last.
Yes. When I plug the phones into the front socket (with an adapter) everything
works correctly. The headset I'm using is a heil pro-set elite.

The question is how long are they? - Ethernet cables are typically 6-20 feet
long. A jumper between the rig and amplifier, much shorter.
Length determines how well it acts as an antenna. The cables I worked with
were perhaps 20-50 feet long, and made good antennas. Some of the ethernet

Obviously the answer is NO they don't disconnect and they don't even turn

The alternative to disconnecting everything is to design your ham

I found John, K9UWA's reply very interesting. Seems a how-to manual

As a side issue - one of the stations down in tampa ended up off the air for a
week. A lightning strike melted their heliax and antenna system was destroyed.
The antenna was on the top of a bank building (about 70 stories up.)-- using

If you include a lightning protection system in your home and radio station
construction, be sure to perform regular follow-up inspections of the
