This information might be interesting for those using the TS-2000 with WSJT modes.
These setting are what I use, there could be better set-ups...
if your setting are different, let me know...
I am always willing to try new settings if they are better.
First I use the ACC2 for all my connections from the interface...
The wire termination of the 13 pin din plug is explained on page 95 or the manual. Everything is isolated, no short cuts here...
The only disadvantage I have found using the ACC2 is that the
Processor cannot be used. If you think it is necessary to use the
compressor then you need to bring your signals in via the Mic Connection on the front. (I have been told that the Compressor will
work with WSJT but I see No Need for It.
Solid State Amplifiers For 2 , 6, 432
I run my TS 2000 at the 10 watt drive for the THP HL-350Vdx amplifier and 20 watts drive for the TE Systems 0552G amplifier
for six meters. Unlike my old IC 746 the Kenwood has relay control for each band from the Ext. Connector on the back of the radio.
It is necessary to go to Menu 28A and turn on each Linear Amplifier control from the default OFF to 1.
DSP Filter Setting:
The Low Cut-Off DSP filter is set to 600Hz and the High Cut-Off DSP filter is set to 2400Hz. This setting seems to be the best for allowing the
WSJT Tones to pass but still rejecting noise outside those set points.
I run with the noise blanker on and adjusted to 10.
If the signal to noise ratio is acceptable, I generally leave this Adaptive Filter off however is pings are weak or tropo scattering is weakly heard I
will turn it on and it Always Helps. I leave the setting of NR1 at "Auto". There is no need to adjust the gain after turning on the NR1, the green line
may just slightly drop down but not enough to make any difference. NR1 only used about 2-3 % of the time.
NOTE: What I am telling you is completely different from what
most people say but the DSP NR1 does not have any negative affect
digital signal being decoded using JT44, FSK441 or JT6M modes. (I use the "Auto" setting only)
I use the AT1 on six meters. Two meters bypasses the antenna tuner so it is not an issue. I use the option for In Line AT while receiving . Menu 27
is OFF, and this might seem strange but if left on the receive audio is slightly reduced and reception is not improved any that I can tell.
Menu 20 and 21 ... I leave both off. The Tx Boost High/Low will cause the calibration setting of your tones in WSJT to change!
DSP Tx filter bandwidth for SSB or AM
Menu 22, I have found 2.4KHz to be a good setting for WSJT.
I always check the ALC reading when a qso starts. I have my controls on the Mic Gain set at 50 for 50MHz and 55 for 144MHz.. I allow the ALC
to work with about three bars indicated on the meter. When operating 6 Meters, after checking the ALC reading I switch to the SWR setting and
verify that reading as well.
I always run with the AGC turned off except for very rare conditions where the noise (Static Crashes) are just too high. The AGC OFF works goof for all WSJT Modes.
I found this to be anoying so I keep the Sub Receiver turned off by pushing on the Sub Knob. Now the RIT is always left on and ready for fine tuning after receiving
that first ping. Hi
I use the Onboard Preamps for both six and two meters however like any other radio, it can be improved with a good quality outboard preamp at the antenna or radio.
Note this should be a good quality preamp if used and should be placed between the amplifier and radio.
Your mileage may be different, but these setting have been good for me.
