[hpsdr] Question about Pennywhistle

[Dan Babcock]

Franck,

1)  Use the small diameter wire in the kit for windings in the center tap transformer (T2).  The large diameter wire is used for the windings in the autotransformer (T2)

2)  Which value did you chose for capacitor C11, 180 pF or 330 pF?

73, Dan N4XWE

Dear friends,
 
Sorry for my english. I’ve bought a
pennywisthle PA, but I’ve some questions:
 
1>     The holes for T2 are very small,
impossible to put wire, is it normal ?
 
2>     The power output from my SDR is
:      32dBm < Power out> 26dBm  
(32dBm on 160m to 26bBm on 10m) what do you think about this delta? Because I
have some difficulty to calibrate PA with power SDR (power 15W to 10W), and
I’ve one problem on 15m, power output is 4W!!!!
 
Many thank’s for support.
73 from Franck F1SSF
