Independent tests prove lack of frequency hopping with XPS

[Kiwi]

OK gents,

I have about a week of playing with the systems under my belt and I'm about ready to put in print the tests and what I have found.

What I will do is start a new thread for each brand and do the videos, graphs etc in them. But system by system as it gets a way too meesy mixing this stuff up in the one pot. Plus I suppose if anyone wants to go back later and see what was said they dont have to wade through 600 posts to find it.

I think I will close the actual data threads after each post. But I will post a link to a discussion thread about the results. Again to keep the chatter out of the data.

Another reason to do it this way is I have been informed of yet another system due out very soon that just might be superior to everything we have available so far. I cant comment on who or what it is but as soon as we get the green light we will have it on FG. Guys I hate keeping secrets but this one has me sworn to saying nothing until the legals are done. However it looks to be a whoop ar$e system. Dont PM me and ask. You guys will know when I know.

So look for the new threads for info. I wont post here much in future unless its just general chatter.

Any guess how long it might be before it's out? (I know that you're not responsible for release dates, just a guess is all) I have the 14ch fasst system on backorder. I'd hate to buy it then find a much more reliable system, but if it's not going to be out for awhile...

Ask me no questions and I will tell no lies.

Be assured when I know you guys will all know. I have no dates, nothing, just information thats somethings in the wind. Not rumors, real facts.

[jonkoppisch]

Keep us informed kiwi!!!

Thanks

Please post links to those other threads when they exist.

You are my hero, Kiwi!!!

I believe that the reason for not doing this (aside from the Polk's thing) is that
a) 72 Mhz does not have enough bandwidth for a signal layer to control frequency agility
and
b) as XJet said, there were more chipsets / knowledge available to implement spread-spectrum on 2.4 Ghz.

Is it going to be produced by our favorite "Extreme" R/C product dealer?

Kraft single stick on 2.4...... lol


Kiwi, I can't wait to see it, whatever it may be. I'm in the market for a higher end 2.4 system right now. I hope that new system might fit the bill so that I have another option to consider.

Ok, I got another excuse not to 'hop' to 2.4GHz yet. Although I do hope this one is not just like the other which claimed to be superior than rest but up to now, still needs to be proven.

LOL.

I am just recalling my days as an RTO. We used FH in our ASIP radios. Program comsec in the radios you want to talk to and nothing will interfere. Radios not on comsec even on FH cant even talk. Probably not allowed to talk about all that but it worked well on those FM radios.

Just thinking about it I wonder why there has been nothing similar for RC? Heck with your own unique ID on a frequency hopping scheme I doubt you would EVER be shot down.

Well the other option is to use a dual link, one link on 2.4 and one link on FM. Sounds impossible??? Its already on the market

The benefit would be that you can now go to the field and have double the amount of comments about why your link will fail !!!!!! LOL

Seriously though, this does look interesting, am consideirng it for my setup. These guys also had a dual band transmitter module, that would allow you to transmit on 72 and 50 (for example) at the same time.
