[Elecraft] [K3S] WSJT-X MSK144

[Bob McGraw K4TAX]

As a long time MS advocate,  "more power.....more antenna".     I run 
500 watts to a 4 element HyGain Yagi at 55 ft.

You can reduce "F Tol to 100 Hz" to reduce the burden on the CPU, and 
use Deep Decode.  The software will configure the radio correctly.  It 
may set the radio to split if and as needed.

Be sure to use Data A mode with the K3S and set the audio levels to 
attain 4 bars indicated on the ALC meter with the 5th bar flashing.  
Unless "others" have a K3 or K3S, .......ignore what they say about 
setting the audio for no ALC.   Elecraft radios do not work nor handle 
audio the same way as "others".

As to other hams, there is provision in the software to work other 
frequencies in the split mode.   This is the small box "TX CQ xxx"  
Again, the software handles things correctly.     This should alleviate 
any concerns with regard to QRM.    As to transmitting,   TX even / 
1st,  I'm not aware of any specific convention.  I've done it both ways 
with equally good results. Again the software will set the correct 
sequence when answering a CQ.

The frequency table in WSJT has 2 different frequencies for MS being  
50.260 and 50.360.    Either have been very productive for me in the 
past 3 days with more than 50 contacts.   I intend to push into the 
first of the week for both daylight showers and evening showers.   This 
morning there is LOTS of activity.

Good luck, this is a great shower to get ones feet wet in the MS domain.
