CAT5 or CAT6 wiring also works better. The best you can -typically-
do with wireless is:
<http://wireless.navas.us/wiki/Wi-Fi#Performance_and_Speed>
802.11b 6 Mbit/sec
802.11g 25 Mbits/sec
802.11a 25 Mbits/sec
802.11a/g turbo 55 Mbits/sec
802.11n 150 Mbits/sec (the best I've seen)

However, with gigabit ethernet and CAT5/6 cable, you can easily do
about 900 Mbits/sec. That's a big plus when moving huge video files
or streaming uncompressed HD video.

It didn't have a 19 KHz filter in the output?

Yes, it did. However, I still could hear a tone, which only appeared
on stereo stations. My guess(tm) is that either:
1. I goofed in the assembly or wiring.
2. The filter was mistuned by me (highly likely as I recall tuning by
ear and breaking a few hex ferrite slugs).
3. The design had problems.
4. All the above.

Very few hobbyist had 'Ultrasonic Spectrum Analyzers' or 'Frequency
Selective Voltmeters' to properly align the trap. I've owned both, and
they are very handy tools. :)

Or:

5: It was a Heathkit. Not all of their designs were great.
