[PCR-1000] A new Pcr 1000 Control Program

Tue, 2 Jul 2002 01:58:49 -0500

Scott,

Well, I was assured that the bleed over was caused by the discone and
pre-amp combination by an old radio person who knows his stuff.  Friend of
mine that doesn't have internet access.  If I remove the pre-amp, I lose the
bleed-over.  With the filter in, all is well again, provided I tune it to
the right frequency.  I don't think the phenomena is caused by the radio
itself, it's the antenna more than anything.  In the regular ham world,
antennas specific to a band are usually used for this reason.  They transmit
better and right on frequency.

Does that make any sense? hehehe

Harry
