Cathy,
You must have the ribbon cable connected. With that connection and the
power turned on the base K2 (no power to the KPA100), you should have
continuity between the center of the KPA100 SO-239 jack and the center
conductor of the KPA100 board RF IN coax.
Yes, the KPA100 Low Pass Filter
I have largely completed building my KPA100, and reached the point in testing
where the speaker works if connected to the base K2 with the signal coming in
through the BNC antenna port.
However, I have been unable to hear anything when the antenna is connected to
the KPA100's SO239 antenna
Cathy,
Could the difference between the headphone output and the external
speaker jack be attributed to the fact that the headphone jack has both
channels (stereo) active while the external speaker is monaural? In
other words, the external speaker jack will only activate the left side
of
I touched up the solder contacts along the path that Don outlined, plugged in
the ribbon cable and RF cable, powered on, and voila! had DC continuity. I can
now hear RF signals from the antennas fed through the SO239. Thank you!
The only issue now is that audio level is noticeably lower when
Cathy,
There should not be that much of a difference. The speaker should fill
a normal room with the AF gain at about 10 o'clock.
Check the polarity of the speaker wires. If you interchanged the two
speaker leads, the speaker audio will be shorted out.
Pull the speaker housing out of the P5
Possible, but the audio level of the KPA100 speaker was also so low that I had
to turn the audio up to full and put my ear next to the speaker to hear
anything. I think there's still an issue here, but I'll play with it more and
see what develops.
