Dear all,
I am about to install my subreceiver and would like to finish before the
weekend but I have no ESD work place. How can I best protect the parts? Or
do I have to wait until I can get the needed ESD equipment?

The P3 frequency display is easily confused by use of RIT. Alan said fixing
it was on the list and I'm just wondering if it's near the top. He posted a
workaround on Nov 10 - using CENTER - but I'm finding I have to use it quite
a lot. It would be much more convenient not to have to :-)

Wear cotton clothing rather than nylon or highly static material; avoid
walking around on static-prone carpets. Wrap a length of bare copper
wire around your wrist and solder a 2 megohm resistor to it. Connect
that to a nearby ground connection. Just ensure that the K3 is always

I used a table away from electrical appliances and covered it with tin

this large piece of foil and worked in this manner. Ideally you would
connect the foil to a ground through a 1 MegOhm resistor. Note I did

Thanks for the note, Joe.
You got me on the oversight of the firmware release note, that's sort of

my desktop icon pointed to Rev D6, not the latest D9, so when I checked the
manual, I found nothing.
Nevertheless,

As the KRX3 manual says (pg 5), avoid voltage differences between yourself
and the components. If you don't have an anti-static mat or wrist strap:

Wes is correct. Please make sure you check:
1. Baud rate on the K3 should be 45 (if that is what your software is
using)
2. If you have the mark freq set to 915 Hz (pitch) on the K3 then your
soundcard software for RTTY must also be 915 Hz.

Many years ago I built a remote antenna switch that allowed feeding up

contained 5 coax connectors,
