Hi Carl and all others!

Thanks for all the positive comments on our signals and receiving capabilitys
during CQWW.

Regarding TS870, I`ve had the rig for abt one year now, and by now feel
very comfortable with the piece of gear.

The first month I used the 870 I discovered some shortcomings. There were IMD
problems in the receiver, especially on low bands - wich I favour...

I mailed kenwoods technical staff and got some suggestions for
modifications wich
they already had implemented in models with later serial no.

In short, the idea was to reduse gain i 2:nd mixer and compensate that with
increased
gain i MF stages.

After I did that mod the problems with IMD totally disapeared! In our
contest environment (multi/multi, 6 stns in the same floor with rugged
amps) the 870
performed very well. Myself I had no interferences from the other bands and
they
did`nt seem to be that bothered with my spectrum either. No treats, and at
least
moderatly happy faces when we run in to each others for food and coffe
breaks....;)

Ofcourse we, as topband-operators, benefits from beeing on the lowest band
with
no second harmonics from other stations. Nevertheless, my opinion is that
the 870
handled the broadband noisespectrum very well!

Hope to CU all on THE BAND this season!
