Independent tests prove lack of frequency hopping with XPS

[jonkoppisch]

I got what you meant Woj!!!! Dusty is wound up as they almost got him too!!!!

Aw, you don't like my video?

[XJet]

I just got banned from RCG because I was rude enough to point out that someone with a 900MHz FPV system discovered they'd get more range by turning on the video transmitter before turning on XPS.

I simply pointed out that if XPS was frequency agile as JD claimed then surely it would hop to the clear part of the band even if it was turned on *after* the video transmitter.

In effect, they were getting twice the range with the video powered up first (XPS second) so JD's claims that the hopping is there to extend the range seems to fail in this scenario. If XPS hopped as a method of extending range then surely, when the XPS was powered up first and the video second, it would eventually hop to a clearer part of the band as the signal strength got lower (noise floor rose).

It seems that pointing out the facts is now verboten at RCG.

I doubt I'll even bother going back to RCG, their moderation system appears to allow a few rogue individuals with agendas to ride roughshod over those who they don't agree with, even when you don't break the rules and simply challenge the claims of a manufacturer.

Money talks I guess.

I'm sure that it will be all smooth sailing over at rcg now that the 'rouge' element has been removed

Time to make another hopping video... Now where did I put that sledge hammer again????

It was pretty good, but dude, jonkoppish had a frog in his. It's tough to compete with that.

[jonkoppisch]

That wasn't a frog... That was a patented intelligent frequency hopping system

Just wait until you see my spherical antenna...

I work in pro audio, and hate to burst your bubble, but the dominant pro wireless systems currently out there are in the 700 to 900 MHz range, single LOCKED frequency, with no hopping. They are single antenna on the TX and dual on the RX, for diversity, as well as the ability to handle variable polarization . . . . and most are simply switched diversity, which is not "true diversity" as you state, where both antenna inputs are constantly in use . . .

My apologies, I took that the wrong way. I'm totally chilled. Thought the video was absolutely hilarious. The perfect video at the perfect time. I guess you and I agree!

Well that shows how little I know about that stuff. I just have a pile of guitars and amps and an old Nady wireless for my guitar with two antennas that has worked perfectly for years, something I can't say about XPS!

kill this thread already!!!

But then again, your guitar can't fly . . . .

I know you hurt that little frogy! I bet you tied him up ,cut him real slow and held a match under his foot while he squealed and hollered ,with an evil grin on you face.

Why? I say just the opposite. We all need to continue the dialog and make folks aware of the XPS short comings.

[JEFFRO503]

I think that this should stay alive....for now!

I also think that KIWI and XJET should start up a new "NO HOLDS BARRED , NO BIASED what so ever comparison between all the systems that are available.


IF JD wants to save any face what so ever , he needs to jump in on this comparison and PROVE his systems worth , and explain to Kiwi and XJET exactly how they should induce a hop , or at least show them a way to not get the system to go into fail safe when another system , or anything in 2.4 is turned on.

Honestly.....you guys that support XPS , this is your chance to help out. get JD to come forward and get in this brawl and let ALL OF US as modeler's and pilots come together and find out.....


WHAT IS THE MOST ROBUST SYSTEM OUT THERE???

I know i'm really curious to see how all these systems stack up against each other....aren't you?


And If you think a certain system "should" be tested in a certain way , ( that is REAL WORLD..and will help you out at the field)...Then for the love of Pete.....PLEASE TELL THEM!!

After these tests are done , there will be NO DOUBT in which what systems are are at the head of the pack.

JD....if you read this , please will you join in and show what your system can do?

FG members are mostly a savvy bunch, do WE need more awareness? A quick glance at the main Radio forums at both RCU and RCGroups, both with MUCH greater traffic than FG, and much greater "newbie" factor (folks who might buy an XPS unit) show no current "XPS Awareness" threads. Seems like if somebody was truely interested in getting the word out, those would be the places where maximum exposure could be realized, no?
