of Tuscon watched WB4APR's APRS talk as their February club meeting
program, and sent this comment:
It was absolutely outstanding!!! Well
received by.all! Due directly to this presentation, we have at
least 15 more APRS stations on the air. Sometimes, technology which has
been out for quite a few years is taken for granted and it can
stagnate. With all the new Techs out there now, this is new stuff
many have not been exposed to.
We will be using many more of your videos in the future.

"Through the Looking Glass"
Phil Harman VK6APH
you on an entertaining, detailed trip through the design of the Mercury
SDR receiver. With the A/D converter preceeded only by a bandpass
filter, Mercury does everything in software, at a price hams can
afford. It is the leading edge in ham radio technology.
The preview for this DVD is the last 90 seconds of the preview video (above). Focused like a laser? Go to 6:55 in and
play (right after the D-RATS segment).
If you are using Mercury and wonder why and how this receiver is so
good, you should (or you must) buy this video! It's a very professional
video, and it is very much more pleasant to hear Phil than to read any
technical paper about DDC, decimation, etc.
Great job, Phil, TAPR and ARVN (Amateur Radio Video News)!
