Make sure the problem is in the radio. Ground the FSK input while the radio is
transmitting and in MONITOR and see if the FSK tone
changes from 2125 to 2295 Hz or vice versa.

Subject: [RTTY] IC11 for FSK/RTTY on rear 13 pin on TS2000
Hi guys
No diddling on RTTY!!!
The radio will not diddle at all, it happned when I changed today from PCI
soundcard to a USB sound card.
Suddenly I decided to disconnected the 13 pin from my microham box to the
TS2000, and I had the power on from the PSU both to the
TS2000 and to the MK.
I know LA7HJA changed two of this IC before, but its so boring to drive 4-5
hours on way to the repairs shop to fix a static
electricity trouble.
Even I had 2 x 4mm ground wires from radio to PSU, I sure got some arc from the
PC?.
So now I cannot get any diddle on neither of my 2 USB MK boxes L
The unit which making the diddling in FSK is the IC11 .
This is IC11 on the rear of board of the TS2000m, and its connected to the
ACC2 13 pin.

do anyone changed this before or have any idea if it possible to solder a IC
frame for the IC11 on the board?
Anyone have a idea how to measure this or to fix this to NOT happen ?..maybe I
should add som 100nF caps to the unit????
