KRC2 and TS480

[STEPHEN BUNTING]

Hi everyone,


I have KRC2 band decoder that I used ages ago with my K2 - it still works
in that I can toggle bands when I hold the F1 button. I want to use it with
my remote TS-480 but the radio CAT isn't currently driving KRC2 at all and
I would like some advice on how to get it working, please.


Current set up: I have used the Kenwood jumper positions from the KRC2
manual and have a straight through serial cable from rig to KRC2. I am
using 4800 baud (W7 and W8 in place) and the radio CAT works with my PC.
The KRC2 is certainly in operate mode and I have a 13.8V PSU attached
(stating the obvious!)


Questions: I suspect I need to apply the handshake jumper between W14 and
W17 for the TS-480? Does the position of W7 and W8 matter for 4800 baud?
I'm assuming the manual is correct. Can any 480/KRC2 users comment on
anything else I have missed?

Hi Steve,

I have KRC2 which works without issue with my remote TS-480.

I had conversation with Gary from Elecraft some time ago and his setup
proposal works OK for me.

Jumper settings inside KRC2:
-------------------------------------------
Jumpers IN: 3, 6, 9, 10, and 21-23
Jumpers 14 & 17 bridged with voltage from pin 7 of U2 fed to this jumper
(~2" piece of wire).

Jumpers W7 and W8 depend of data rate, see KRC2 manual page 20

Hope it helps

Steve,

You will have to refer to your TS-4800 documentation to determine the
data rate (setting for W7 and W8 jumpers) and the proper setting for the
handshake jumpers W14 and W17.
I do not have a TS-4800, but the manual should tell you what is needed
and then the KRC2 manual will tell you how to plug it.

And for the list record, I can report that the mods reported to the group
by Robert, S57AW, work a treat. My TS-480 now talks seamlessly with the
KRC2. Thanks again Robert!
