I've done quite a bit with the Spectras; hacked the software, re-tuned the VCO after modifying, re-capped them, etc. I think they're great radios. Just thought since it's difficult / impossible to get maxtrac filters, and knowing how good the Spectra receivers are, they'd be a nice alternative to go with a Motorola Nuc as a receiver.
Not sure that there is COR present on the 15-pin accessory pin, but seems like when I looked at that before there wasn't. I'm sure that can be found somewhere inside the rig, though. Can you e-mail me off the list with what you have? Thanks, James On Sat, Nov 21, 2009 at 9:35 PM, John Gleichweit <smokeyb...@sbcglobal.net>wrote: > > > I'll second the motion for a write-up.
