[Kenwood] Problems with YG-455C CW-filter in TS-830S

[hans@remeeus.nl]

Thanks to Clif I found out that the YG-455C-1 has a centerfrequency of 455.0
kHz and the YG-455C of 455.7 kHz. That was the problem! The TS-830S needs a
YG-455C filter.

Fortunately I already found a YG-455C and I may return the YG-455C-1.

During this I found out that my TS-830S was not yet modified for
TX-operation on the WARC-bands. I cut the blue wire between the RF- and the
AF-board, because cutting the three diodes seems to me as a 'mission
impossible' without removing several other parts. The blue wire was very
easy to find.

I also found the YK-88S2 filter (to install instead of the standard YK-88S
filter) and I hope to find a CFJ455K12 or -V12 sooner or later.

Very nice rig this TS-830S, especially between all the modern DSP-rigs we
have today. The TS-830S sounds very good and makes improvements and
modifications still possible.
