[1000mp] Inrad CW Mod Install

Wed, 14 Apr 2004 19:23:15 -0000

Hi Art.

  Just read your comments re the AMRAD keyclick mod. I was planning to
do the
W8JI mod for my FT1000MP, which has bad keyclicks, and wonder if the
AMRAD mod
is available over here in the UK, and how it compares to the W8JI.
Wonder if you
know of any such comparisons?

Hi Dan,

I am glad to hear you did the mod.  I did too and I do hear the
difference.
You say you couldn't hear your rig's key clicks.  Out of the box they
all
do.  What is deceptive is that the FT-1000MP's signal sounds great on
frequency.  You have to tune off frequency to hear how badly they
click.  If
you want to hear an example of this listen to the big gun multi-multi
contest stations in the next CW contest.  I believe the many of these
stations use unmodified FT-1000MPs.  These rigs are used for contests
only.
(A whole other subject is that multi-multis have incentive not to
clean up
their signals.) Anyway tune across their signal and note how far up
and down
the band you can detect it, easily 5 to 10 Khz.  I'm not being
critical of
contesters.  I just offer this as a way of hearing how badly
FT-1000MPs
click.  Another way to do this is find a station that is clicking far
from
his TX frequency.  Look up his call on QRZ and see if he has web link
or
photo of his shack posted.  I've done this several times and found
shack
photos that included FT-100MP.  BTW I am aware that most rigs click
out of
the box.  I'm just saying that unmodified FT-1000MPs click quite
badly.

Just a FYI to the group. I installed the Inrad CW mod in my 8 year old
FT-1000MP yesterday. It took about two hours to install and reassemble
the
radio. The topology of my  PCBs seemed a little smaller than the
boards
illustrated in the service manual and the instructions that came with
the
mod. I insulated the leads of the caps and resistor with tape and
insulation
stripped from a small wire. To be honest, I never could detect any
clicks on
another receiver, nor did I ever receive any reports of clicks. I did
look
at the output siognal on a monitor scope before I did the mod, the
raising
waveform looked good but the falling part of the waveform was straight
down.
I haven't looked at the waveform after I did the mod. After assembling
the
radio, I made a few CW contacts with good reports. I asked for reports
of
clicks from the stations I worked and all said the signal was clean. I
am
sure someone with a scope or spectrum analyzer could give me a better
idea
of what the signal looks like. Installing the mod was much easier with
a
copy of the service manual. I got mine at w7fg.com. If I can answer
any
questions for anyone thinking of doing this mod please contact me.
