What is the possibility of 72MHz radio systems being gradually phased out by 2.4GHz technology? It will be interesting to hear some thoughts on this from various aspects.

I'm waiting for everyone at my club to get a 2.4 GHz radio so I will have the only 72MHz and and not need one 8-). I suppose it is inevitable. Just as rotary dial telephones were phased out for touch tone telephones, so will the 72MHz be some day. Prices will come down and more and more people will get the newer transmitters. The problem I have for the 2.4GHz is the price of the receivers. I am a sport flier and to change out 6 72MHz receivers for the newer ones is pricey at this time.

Long time ago I flew on 27mhz.. now 72.. and soon 2.4. It's difficult to imagine the Mfg's producing old tech for too long. It's just another added expence for them.

My guess, and that's all it is, is that the FCC probably wants the entire 72 MHz band to sell to commercial users. The frequencies between ours have already been sold so with 2.4 GHz available, why not make some additional money? My second guess is that it will be awhile, though.

no its here to stay that is why i am not throwing away my cassette, vcr tapes, my large DVD's and my reel to reel, 8 tracks either

Does anyone know if you could design a spread spectrum 72Mhz system that would work on the channels between what we have now. . . kinda like the HD radio frequencies on the FM music band.

I suspect at some point the 72MHZ radios will no longer be made but I doubt we will
see a significant change untill about 5 or so years.

You forgot to mention your non HD TV set.

As far as I know, there are no 2.4 receivers small enough for some indoor and HLG. Also, 2.4 doesn't work with all carbon fuselages. They'll need to get these types of issues sorted out first. I'm staying with 72 for the time being because I've never had a problem with it and I'd rather spend the money else where for now.

2.4 Ghz technology is probably here to stay. There will be system improvements as experience is gained. Just like regular TV and HDTV, I would not expect 72Mhz to become obsolete any time soon. There are some flying sites where 72Mhz may be more stable than 2.4 Ghz. Just my $0.02 worth. I'm still going to keep my JR frequency select module and R2000 scan select Rx.

Assuming normalcy in accounting systems as volume goes down costs go up. The Distributors will really be the ones who determine the end (yes, ultimately the user)------When? Good question----and one for which there is no answer presently.

Could be a couple of years, could be five, could be ????------BUT the FCC will have to allow for reasonable "use times" for existing equipment. (perhaps that should be the FCC has, in the past, allowed for reasonable "use times")

with everyone going to 2.4 it will give us on 72 a little more time to fly not haveing to wait for a ch to free up, an not take so miny hits

Has there been any real talk on the FCC's part about wanting our 72mhz spectrum? I'm far from an expert and speak from a position having zero facts here, but I don't believe that the change to 2.4ghz is being pushed by the FCC. It's an industry and demand driven innovation. I have heard nothing about the FCC offering a slice of the 2.4ghz spectrum to RCers, nor of them encouraging the development of 2.4ghz gear. Given that the FCC isn't involved, it's not as though they've got a sunset time planned for our 72mhz use.

There are still 27mhz systems out there. Plenty of AM 72mhz systems, too. Change happens slowly, and I believe most 2.4ghz switchers will change because of new capabilities being offered now and in the future, rather than by some as-yet nonexistent government mandate.

Hi;Just my thought on question!Live in Northern Wi on Lake and fly floats there no reason to ever switch over,My old AM wrks fine even!DUring winter live in Az and fly next to a military research facility with many unexplained glitches etc.WIll be changeing those planes to Spread Spectrum[sp] When I return,receivers are cheaper than planes but won't know for a while if it will do any good!!Just my .02

When you see trainers conbo's that have 4 ch radio's that are 2.4 then you will see the end of 72. Just look at the E- Flight CX2 at $189. it has a 2.4 gig 5ch with it. Dennis

My feeling is that as licensed users press the FCC for additional 72 MHz channels they will have a reason to eventually end our use of 72. Money talks and we don't make the government anything, licensed users do. If the RC industry has an alternative to 72 MHz and the FCC can make a case that we have been given plenty of time to switch over, they will do it. It may take some time, several years would probably be the case, but grab the frequencies they will.

Seems like a strange question considering the manufacturers don’t seem to be capable of shipping anything 8 channels and over.
