[TenTec] Orion vs SDR-1000

[Bill Tippett]

	Orion has some new competition!  See
the ARRL Product Review in October QST.

IMDDR3 at 2 kHz is 99 db versus Orion's ~92 dB at
the same spacing (using the stock 1000 Hz roofing
filter).  BDR is not as good with the SDR-1000 about
10 dB worse than Orion at 2 kHz spacings.

	I still do not understand why IMD improves
with preamp on, but that's what ARRL measured
for both rigs.  Doesn't seem logical to me.

	The transceiver is $1375 assembled and
a RX only version is $899.  You also need a
M-Audio Delta 44 Soundcard which can be found
for <$100 on a well-known auction site...plus PC
of course!
