[RTTY] ts870 fsk + Warning abt unplugging at kenwood ACC2

[Don Hill AA5AU]

I have plugged in and unplugged the FSK input of my three TS-870's on many
occasions with no problems.

This must be a problem with the TS2000.

Hello 

I and my friends have expiered that our Kenwood equipment stopped "diddling"
just a single tone. 
This means at our TS2000 while TX'ing either with RASCAL MKV or Microham's USB
Keyer.
1th RIG :One time this IC on the FSK pin at TS2000 went down, it worked ok with
Rascal but wasnt able to work properly with microham box. After disconnecting
the microham box, the IC went total dead. Nomore diddle out of the TS2000. SO
NEVER try this. NEVER disconnect while Txing...it is mostly your software.
2nd RIG: Worked nice with RASCAL, suddenly no more diddle. Got broken during
contest. This is coz I had disconnected the cable as I know with the computer
switched ON.... 
3rd RiG: works ok coz we have knew abt the problem, and do 100 % procedure, when
we disconnect cables we switch off all parts which can destroy this IC.

So this can maybe be your problem also on the TS 870 ?

The service technician at Permo Electronics said that you cannot replace this IC
with a Mitsubishi equialent, coz this one coz broken after some time. The
orginal TS2000 part works much better, or in worst case u can change the whole
card in back of radio......

So I will never unplugged like I did b4 coz its very boring, I always use my
time to wait :)

The fsk modulator in my 870 has quit working. Menu settings are correct and
interface is working properly. Any help before shipping off would be
appreciated.
thanks
