(Between 34 ☌ to 35 ☌ up&down max.) These <1.0 Watts output I take as drive-power for a little separate 30 watts homebrew MOSFET-PA or the KXPA100, but use with it not more then 5.18 Watts output ! The results are very good : To aproximately 95% all contacts or answers on a CQ- call in Mode JT9 are successfully !!! Also the mode JT65 is without problems and working stable. The temperature varies between TX / RX sequences with JT65 or JT9 sessions only +/- 1 ° C. In operation, with less 1.0 watt output of the KX3, I have the oscillator temperature observed. Than I decided start to go the way to prepare my KX3 especially for use the Mode JT9 : At first I have done the : KX3 EXTENDED VFO TEMPERATURE COMPENSATION PROCEDURE ! This procedure description You can find HERE ! Never I have used or was thinking about a additional heat-sink ! After I done the procedure of temperature compensation I have NEVER RUN MORE THEN 0,5. With the FT857D I had no problems with mode JT9. So, the FT857D seems to be in a good shape for working in JT9 and stable enough. So I have at first compared operating JT9 with an FT857D with additional built-in TCXO (frequency-stability <0,5ppm). I was wondering why I got most NO answers if I worked in JT9-Mode at first time with the KX3 and only 3 watts output used.
See HERE WSJT-X Mode JT9 Signal-Decode-Example with use KX3. Read on the Website of K1JT (JT9) more precise about The differences between JT65 and JT9 ! The KX3 is also well suited for JT9 because the TX (ESSB) and RX bandwidth can set very good how needed to 4 kHz ! Some critical to the use of Mode JT9 with KX3 is only - the not necessarily sufficient - frequency stability of the KX3 of (+/-) < 1ppm.

To start the program : You must in program properties configure and chosen "Let run under Compatibility-Modus for Windows -7 " and also You must chosen "Let run as ADMINISTRATOR ". My experience is - to solve this problem - You must let running the install-routine (.exe) as ADMINISTRATOR.
