I have an Omni V with the N4PY V.9 upgrade. As far as I know this radio works ok. Cosmetically it is at least a 9. It has 1.8 500 and 250 filters in the 6.3 mhz, none in the 9mhz slot. I also have a Corsair II and have been doing A/B comparison. I find that I like the Corsair II as good or better than the Omni V. Is anyone interested in a trade, the Omni V for a Centurian Amp? 73 de Paul K9OT
