[DSP-10] Audio filters question

Sat, 15 Mar 2003 05:52:28 -0800

Hello Bole!

You need to edit the UHFA.CFG file.  The line that says "hardware 1" must be
changed to "hardware 0".

And the audio input to the EZ-Kit is on the middle contact of the connector
rather than the tip, so you *must* use a stereo plug.

Finally, you must select "tranverter 15" which is selection "o" (letter O,
not the numeral 0).

I went through these steps last night, and used it with my Elecraft K2 :-)

Also note that if when you run UHFA on the PC it says it can't download some
filter coefficients, that really means it isn't talking to the EZ-Kit and
you need to restart the whole procedure.  At least this is what it appeared
to mean in my case.

Good Luck!

73,

Lyle KK7P
