    Default Bel 985 Tech Display??

    Does any know if this unit displays the exact frequency of the band received? Specifically, if two different frequencies are received, will the unit alternate back and forth between the two and give you an indication of how many signals are present?

    I know you asked about the 985, but it made me curious about the others. So I just tried this with the RX-65 and X50. Both of those will only display the frequency of the strongest signal, and will not alternate between the frequencies of different sources.

    My question still remains. If I come upon a known freq (false), and then there is another stronger signal (Leo ), will I get a different display and hence a warning? "Leo" and "false" are not the same frequencies but are the same band.

    Jim pretty muched answered this.

    But I will just reitterate, and I have a 985, in my experience just as Jim said the stronger signal will dominate, that does not mean becasue you right next to the stupid auto door false that you will not know about the LEO.

    Obviously if the LEO is shooting Ka, Ka will always over ride K unless the LEO is shooting instant on, so the false will alternate inbetween.

    Now I just thought about X and K (for those that still have X threat) now that is a interesting question (I never thought about I do not worry about X band), K over rides X but if your next to a K false and a LEO is shooting X, will you know???

    What I was going to say, is that in my experience all my "falses" have been relatively weak, so that any real threatening radar which will be naturally stronger will be given priority!

    NOW here is the real world example you have been waiting for...

    I have a known K band false at a intersection, south from the intersection there is a mobile speed sign setup (shooting north bound traffic) about 1 mile down the road. I am approaching the intersection traveling east bound and preparing a right hand turn to go south bound. This is what happens. I initially get the weak "false" at the intersection waiting to turn south, but then I get it alternating between the speed sign radar that is also weak becasue it is not pointing at me. Obviously as soon as I turn, although the mobile speed sign radar is still weak it very soon dominates over the "false"... and the nthe "false" is out of view it completely goes away.



    You do see alternating frequencies but only when they are equal strengths, in my experiences a LEO will always dominate over a auto door opener "false".

    NOW if there are two LEO's shooting radar in the same area so that they are equal strength (both same band), then you will get alternating frequencies.

    The RD is designed to always show the most threatinging source. Again in my experience the only way a false will dominate a LEO is if the LEO is far away and not a threat.

    Just what I was hoping, RX65 tech display performance from a Bel Vector 985! Oh, did I mention AccuSweep and quick response. This feels like my favorite detector for less than $100.

    Just to be clear, the rx65 has a mutithreat display, so you can see mutiple threats even if one is weaker then the other, this could be helpfull, but our units will more than sufice and do the job.

    I went cruising to test my newly repaired 985. I did find two cops, both with radars transmitting on Ka band. I knew from the V1 bogey counter they were both running their radars. Only one frequency was displayed on the 985 Tech mode display. So this confirms what the others have said.

    The 985 Ka sensitivity appears to be good maybe even slightly better than before the repair. It is on a par with V1 (1.7). The only thing that worries me is that, on one of my runs at the radars, the 985 was not reporting a signal, it dropped out and then started reporting again later. I only had the 985 on during that run. When I ran the V1 only against the radar, the Ka report did not drop out. I wonder if this is something to be concerned about?

    The cops were outside of their patrol cars the entire time. I saw one of him lock his car door. So it is unlikely they turned both of their radars off during this time. They were busy talking to the driver that was pulled over.

    Could two radar signals (if they were out of phase) cancel each other out. V1 was designed to track multiple signals so maybe it would be less prone to drop out.

    I would have to say probably not, the odds of such an occurance happening where they cancel each other out would be very miniscule (since they are running [slightly]different freqeuncy's in the first place)... I guess we shall await Jim and his reply to the subject.

    I figured that could be a longshot. Further testing will be required to see if the signal dropout is a common occurrence. If it is, I will have to send it back. Someone else I know sent their BEL 970 back five times before it was finally repaired successfully. My past dealings with BEL customer service have been good, but that was before the merger.
