Future of 72Mhz
 

Hello all,
I've had some interesting reading about the future of the 72 Mhz band once the FCC opens it up. Some say the crystal recievers and radios will fade away, other say the band will be so over used by 'others' that it will be unsafe and we're forced to 2.4 gig.
My only objection is the financial crisis, job loss and job insecurity making it tough for everyone to just 'bounce' up to the 2.4

RE: Future of 72Mhz
 

Maybe the government will bail us 72mhz guys out and buy us all new radios:D:D:D

Blessings,

Jay

RE: Future of 72Mhz
 

when does the fcc plan to open the band up?

RE: Future of 72Mhz
 

Airtronics is already working on it. $229 for a very capable radio with TWO recievers!

RE: Future of 72Mhz
 

I don't know exactly when FCC will open it up or 'if' they'll open our section. I did try to call the AMA today........ right...... automatic menu with no real person. I was on hold for over 15 minutes, then got the "everyone is too busy" message. Hmmmmm, never too busy to take my membership $$

RE: Future of 72Mhz
 

Where did you find this information? I'd like to read about it.
Thank's :(

RE: Future of 72Mhz
 

I just did a search on google for the futer of R/C 72 mhz and hit a lot of threads to forums like this. A couple of guys at my club had heard the rumor going around.
I'm not trying to put a scare out, but if that's even a possibility, I wrote my local AMA VP (no response yet) and suggested that the AMA have a strong lobby against dismanning the 72 ban.
A lot of the threads related to the 1991(i think) change to the narrow ban and booting the borad band radios. THAT was a good move, it saved a lot of hassles.

I think 72 is here to stay. Now that the radar jamming gaggets are takeing there toll on 2.4 systems.

RE: Future of 72Mhz
 

I think it is only logical that 72 will not be available to us. One of the AMA's most important benefits to us Rc'ers is that they lobby to keep our frequencies free. That is not really necessary now with 2.4 and to be honest other than having the cash, there is almost no reason to stick with 72mhz. I have not bought new radio equipment yet because I cannot afford it. As soon as I can though I will outfit all of my larger planes with 2.4.
To me one of the major benefits is not having to secure your frequency at large fly-ins where you have to wait for your frequency. That my not be as much of an issue with the move to 2.4 but I also do not want a $3,000 that took a couple of years to build get shot down by someone not paying attention with their transmitter.

RE: Future of 72Mhz
 

Our district AMA V. Pres. just replied to me and the AMA is hearing the same rumors, but have not been notified yet about any changes or mandates. He feels it's safe for a while. What's the issue with radar jamming, is it affecting the 2.4 gig R/C band?

RE: Future of 72Mhz
 

I hope they don't get rid of the 72mhz... I like them better than the 2.4, but that's just me.

RE: Future of 72Mhz
 

I want to stay on 72; I have no reason to change right now. What was bad was how people jumped to 2.4 so fast that the FCC might think no one is on 72 and give it away. I like 72 better and wont need a new TX for years.

RE: Future of 72Mhz
 

That's why I'm bringing it up. Make sure to email your local AMA V.P. and ask about lobbying against dismanning it 'if' it should arise. The economy sucks bad enough, a lot of our memebrs are on limited work, lay off or retired.

RE: Future of 72Mhz
 

So far other then not needing to get a pin or impound your radio I can't see why I would ever want to go over to 2.4, I have seen too many problems with it that I haven't seen with the old 72. Good thing about 2.4 is I haven't run into another pilot on my Ch. in quite a while. I can't see myself having to spend seven hundred bucks on another radio.

RE: Future of 72Mhz
 

That's interesting Gray Beard. What kind of issues have you seen? another person (above) mentioned something about radar jamming? I had one mfg. tell me that they were uncertain about the 2.4 after the TV stations all went to digital, but that's been postponed until June now. I don't know what his concern was though.

RE: Future of 72Mhz
 

If you notice very few 72 mhz radio's are being offered by the radio mfg's and
almost all the new radio's comming out are on 2.4 ghz. I think in 3 to 4 years
72 will largely be a thing of the past and at some point im sure we will loose
the band.

RE: Future of 72Mhz
 

Hi masonman
Please let me know what you mean by "Now that the radar jamming gaggets are takeing there toll on 2.4 systems". I have never heard of this and all of my equipment is 2.4.

RE: Future of 72Mhz
 

I was not aware that that the 72 Mhz band had been abandoned by TV broadcasting.
The change was in the modulation method, from analog to digital, not the frequencies
in use. Then again, I hav'nt been paying that much attention to the issue.

RE: Future of 72Mhz
 

The FCC DID open the 72 MHz band several years ago. Its used now for commercial mobile use. There are 4 of thier freqs between each of our channels. I believe its also use to transmit digital data on power lines.

RE: Future of 72Mhz
 

Would that have been around the time they changed us to 10Khz bandwidth from 20Khz
1991 I think?

RE: Future of 72Mhz
 

Yep, the Land Moblie Radio Service. Their channels are close to ours.

To get one with a lot of range it is $$$$$$$$$$$ but they do exist. They may or may not be legAl to use in the US.
But, laws do not stop people from doing illegal things; they only punish those who get caught.

RE: Future of 72Mhz
 

The 72 mhz is still in high demand, and is still selling well. It doesn't make sense to me to quit making something that is a proven and time tested thing. But also to me, getting rid of DVD's and having everything Blue-Ray doesn't make sense to me either. [&:] Oh well.

I'm on this notion of an old Navy saying... " Believe half of what you see, and nothing of what you hear." Until it is written in stone and right in front of me, then I will not believe in this rumor. :eek:

RE: Future of 72Mhz
 

I fly 72 mhz both am and fm never had a problem and have no need to go 2.4,just like I do not have an hd tv and have no need for blu-ray

RE: Future of 72Mhz
 

2.4GHz jamming devices and any others like it are most definitely illegal to use in the US. The typical fine starts at $10,000 and goes up from there, and I personally know that users of the devices are caught and indeed fined the $10,000+. Regardless, I really see it as a moot issue and not justification for not moving to 2.4GHz. I believe it is only a matter of time before we lose the 72MHz band.
