Well, I received my 78SE in the mail a few days back and have been happily testing it ever since. Had a very nice K-band encounter tonight on a pizza run.
My settings are normally:
All bands on
Auto-QUiet and Auto-dim on
I approached a K-band Your Speed trailer from behind, and the Pro-78SE alerted steadily (albeit on X-band, since they're on the same sweep) for probably three tenths of a mile prior to the sign being in sight (around a slight curve.)
On the way home, I took the same route, only I put the 78SE in CITY2 mode. The route home took me down a LOOOONG hill, and the trailer was about halfway up the other side of that hill. So like driving down into a valley and back out, with the trailer halfway up on the back out route.
And this is an area through which I've driven frequently and get NO falses.
I was pleasantly surprised to get the first K-band hit, at a strength of 4-bars, almost a mile (.91 miles) from the trailer. DOesn't seem that long, but if you look at the chart below, you can see it's actually around three separate curves AND slightly uphill from the trailer. I lost the signal for a few seconds, but I'm pretty sure it was due to me being below the trailer on the hill, and out of the beam. I was right back in it pretty quick, and ramp-up was excellent, as it has been on all three of my WHistlers (Pro-73, Pro-78, and this one).
So far, my overall impression of the RD and its changes from the regular 78:
1. Auto-Quiet is improved. It's actually QUIET when it does that, not just less noisy. NIce change.
2. The voice alerts remain very good.
3. I still don't like X and K being on the same sweep -- makes for some signal confusion, but that seems to be remedied by switching to CITY2. That allows K to be reported as K, but I have yet to see an X reported as K in CITY 2.
4. The RSID feature is really neat. By displaying the frequency only when it's within a certain window of a known police radar freq, it allows you to put some quick analysis into your reaction. The generic Ka alerts I've gotten come from either other RDs, or from other non-police radars (like the perimeter defense system at a local military base.) I still slow down for the generic alerts, but I don't react as severely.
5. Filtering. For Laser -- OUTSTANDING. I have yet to receive a laser false. Not from Toyotas. Not from Lexuses (Lexi?). Not from the airport wind shear detector. My buddy runs a 9500i, and while his ranges are better than mine, the laser filtering is bleh. He can't go around the local runway without getting a headache from the wind shear detector. And I know I can always block out a laser false if I should get one, something his 9500i cannot do. (If there's a software fix for his 9500i to fix that, let me know so I can tell him...) For radar falses...it's a mixed bag. I was a little spoiled by my old Pro-78, since Mike had tweaked the filtering for me and a Ka false was so rare, I can't remember the last one I had. On this one, I get a few more Ka falses (maybe 1 a day), but X and K falses seem (so far) greatly reduced, even around known door openers.
6. Range. So far, I have yet to encounter a confirmed cop with this. Of course, when I had NO RD for a few weeks, cops were EVERYWHERE. WIth the SE, I had one 35.5 hit, which ramped up a little then went away. Pretty sure that was a LEO in a local neighborhood. But K-band range seems at least on-par with my old 78, and possibly a little better. I had one encounter with a Your Speed sign that was a little discouraging, but then I talked to other users and their range against it was down too. Seems like some tree overgrowth is affecting the signal or something stupid like that. The second encounter (pictured above) was very encouraging, and the best around-the-curve detect I've had with any of my Whistlers.
I'd really like to run into some no-kidding LEO Ka, sometime soon, but apparently my commute times don't coincide with their patrols. The 9500i user, who comes to work 90 minutes after me, runs at least two traps on the same road, both Ka. Ugh.
Maybe I need to go in late one day...
