It's interesting to compare the ORION's numbers against the venerable OMNI
VI. In a QEX article (9-10/02) T. Raczek included a table showing the
drop-off in performance between measurements at 20 kHz and 5 kHz spacings
for a bunch of transceivers. The OMNI fell off 9 dB in BDR and 14 dB in IMD
DR--one of the better results. The ORION, for all practical purposes,
doesn't fall off at all, according to the new ARRL data.
John, I've always been puzzled why the Omni VI was not better
in the measurement comparisons. It has basically the same front-end
as Orion's Main RX (ham band only and narrow roofing filters at a 9 MHz
first IF). Seems like it should do better than is does.
