Hallo,
just a quick note to the list that my new assembled KX1 serial number #585 with 30m module and atu also is alive. I made my first QSO`s two days ago on 40m and 30m. It works great - tnx to elecraft - perfect ! No proplems only the selfmade
( first installed resistor was not the right - sri !)
Here are some values after building:
Results of power-measurement KX1 # 585:
After realignment with 30m-modul
Ub = 14 V:
40m: 40,4 Vss / 500mA ~> 4,08 W 42,2 Vss / 4,45 W
30m: 44,2 Vss / 460mA ~> 4,88 W
20m: 37,8 Vss / 700mA ~> 3,57 W 39,4 Vss / 3,88 W
Ub = 13 V:
40m: 38,2 Vss / 460mA ~> 3,60 W 39,6 Vss / 3,92 W
30m: 41,2 Vss / 440mA ~> 4,24 W
20m: 37,8 Vss / 640mA ~> 3,57 W 38,6 Vss / 3,73 W
Ub = 12 V:
40m: 35,6 Vss / 460mA ~> 3,10 W 36,8 Vss / 3,38 W
30m: 38,2 Vss / 420mA ~> 3,60 W
20m: 35,6 Vss / 580mA ~> 3,10 W 36,8 Vss / 3,38 W
Ub = 11 V:
40m: 32,7 Vss / 420mA ~> 2,60 W 34,6 Vss / 2,99 W
30m: 35,2 Vss / 390mA ~> 3,09 W
20m: 33,2 Vss / 500mA ~> 2,75 W 33,8 Vss / 2,86 W
Ubatt = 9 V:
40m: 25,4 Vss ~> 1,60 W
30m: 25,5 Vss ~> 1,63 W
20m: 26,1 Vss ~> 1,71 W
ZL = 50 Ohm, Oszi TDS 3054
I hope it will be helpfull
have a nice evening - best 72/73
