problem" in all the years of FT-1000/MP/Mk V manufacturing, I doubt
they would admit guilt and publicize when the Mark V mod was made.

I just found this, so the answer is mid-2004 (point 2 below):

Key Clicks and the Mark V Field

Hello from Gary NL7Y in Fairbanks, AK. Here's my tentative thoughts 
regarding the Yaesu key-click issue. I'm on my second Mark-V, the 
first was a used 2001 production 200W version, and the current is a 
Field model. I like both. The first blew up some stuff in in the 
output (tuner/finals/?), and that was apparently a common occurrence 
in some early models. According to Burghardt (Jim via phone), Yaesu 
was aware of the problem, but neglected to address the issue until it 
started to cost them $$$$ in warranty repairs. Contact Burghardt or 
Yaesu for details if you're so inclined. The current 200W models are 
apparently better, and the older ones are repairable. I returned mine 
to the selling dealer (The Ham Station - also an honest dealer) for a 
used equipment warranty refund, via Yaesu repair Service, and 
exchanged it for the Field model.

I have the Inrad click mod ready to install, plus their roofing 
filter in the Field model. So, for the heck of it I just called Yaesu 
Service Support and was told that:

1. Installing the Inrad click mod would not void my warranty if 
properly done. The "Inrad stuff was good";

2. Yaesu addressed the key click issue in mid 2004 as referenced in 
an internal Service bulletin (number not available - I asked) read to 
me by the support technician, and;

3. Owners experiencing problems with their rigs need only return 
their unit to Yaesu for repair or upgrades. I didn't ask if it was a 
warranty item.

I guess this means a "factory" fix is available, and interested Hams 
should contact Yaesu and see what Yaesu can do to help their 
customers. I'll likely not install the Inrad mod unless someone finds 
out something to the contrary. GL. 73 Gary

Addendum: Someone forwarded some very good news from Burghardt Radio. 
I only wish Yaesu would publish the S/N's this is effective for. 
Better late than never! 73, Bill W4ZV

Yes, recently Yaesu did install what is the equivalent of the Inrad 
CW keying mod in their new radios coming off the line. Can't tell you 
serial number change but it has been done on the ones coming off the 
line now. We have been installing it in all of our used ones for 
quite some time. 73 James C Smith (W0MJY) Burghardt Amateur Center
