I dug through all my notes and etc and kept wondering why 9-1 was not
To Google I went. A fellow in Germany how to get into the hidden menu on
of the 1000. His info pertains more to the 200 watt model but he does
give some details
I was missing. Here is his URL www.dg8fbv.de/*ft1000*.htm.
It pertains to the filter board I mentioned in my first message (which I
haven't installed) and
he corrects several settings with different values to get better
performance. His page did
not display quite right on my screen but I see what he is talking about.
I have two Field 100w manuals and neither mention 9-1 at all. So am
glad to learn this
Have a full tech manual for the 200 watt model when I find where it is
hidden. Hi. It
may shed some more light.
Also discovered via Google that there are a large number of videos on
to our rigs. Some are in other languages. But will delve into them
later tonight or tomorrow.
May attempt to replicate your setting on my xcvr. I need to replace the
battery since I have
had it about six years or so...RS has them.
I have file cabinets full of shop manuals and correspondence with most
of the major ham
manufacturers during the years I was running sales and service. I made
it a practice to
buy a manual for each item of new equipment that came out. A person
can't have too much
service data although some of my good friends argue the point since so
much of my house
is filled with them. I sold and serviced high end audio equipment as
well. Never met a
book I did not want.
