Re: [RCSE] How long will 72Mhz remain open?
From: Doug McLaren [EMAIL PROTECTED] However, the local Fry's sells toy helicopters on 72 MHz. It may be that in a few years 72 MHz is unflyable with any `expensive/breakable' plane due to the toy R/C planes/helicopters that have popped up everywhere. It seems quite likely to me that the R/C usage of 72 MHz band may be *increasing* rather than decreasing -- for every one of `us' there's a bunch of kids with R/C toys. They're mostly on 27 or 49 MHz for now, but this could certain change, especially once they decide that they need more than six channels ... Hi Doug et al, So do these type of rc toys not have channel designations indicated on them? I mean if you see 1 at a field and go up to the flier and ask what channel they are on, will we be able to determine to see if there is conflict?

[RCSE] Clinical trials for cataract and glaucoma topical drug.
FYI: Clinical trials for cataract and glaucoma topical drug. Popular Science April 2008 issue page 40 has an article under Med Tech with a sub title of A new drop washes away cataracts in aging eyes. It may be very appropriate to pilots that have been exposed to direct sunlight for many years. Very interesting. You can also read about the drug and the company that is developing the topical medication at: http://www.chakshu.com/ They also mention glaucoma, dry AMD, diabetic retinopathy and uveitis. The company is currently in clinical trials for cataract and glaucoma. This is a link to a Reuter's article that points to the above web site. http://www.reuters.com/article/pressRelease/idUS101183+11-Feb-2008+PRN200802 11 The PopSci article states that the man that developed the treatment used his legally blind dad as a guinea pig. After 3 months of daily drops his father's vision had improved to 20/80. John RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] How long will 72Mhz remain open?
Bill, I wouldn't expect any dire consequences for the 72 MHZ band. I could see in the near future where 2.4 will become the choice, and expectation for contest flying. However, I can tell you that the folks at Horizon will continue to support their 72mhz range of equipment, and they have no plans to discontinue 72 Mhz gear at this time. I just ordered a 790 RX this morning because I am finishing an all carbon F3B model that I don't want to mess around poking holes in the Nose for. I looked at the flyer for the New JR 12 channel and it will be offered on 72 Mhz. My own thoughts will be that most of the companies will maintain 72 Mhz gear as long as it is a viable business option. My inclination would be to keep selling product as long as people want it. So I guess, We will decide how long 72 Mhz holds on. Best Regards Larry So now that 2.4 Ghz is emerging in force; how long will we continue to have FCC approved access to the 72MHz band?

[RCSE] Welcome to the IHLGF 2008
HLG Enthusiasts Worldwide: The Torrey Pines Gulls and HORIZON HOBBY and JR Radios, our 2008 Co-Hosts, are please to announce that the 15th IHLGF will be held June 7-8, 2008 in Poway, CA (30 miles northeast of downtown San Diego). This great event will have a few new wrinkles. This year we will be using the newly adopted international FAI F3K Rules and tasks. We have made a few exceptions to the rules but they are mainly Poway field specific. As I went through the F3K Rules (which include the tasks), I was surprised at how close they are to those that we have used for years. I guess that original input we made to the F3K process years ago, plus the influence of the international pilots that have participated in the IHLGF over the years, actually had some influence on the final product. The other wrinkle is that we are opening up entry for the IHLGF 2008 immediately. You don't need to wait till April 1st as in the past. Click on the IHLGF 2008 website and get all the information on the event and register while you are at it. Here is the link: http://www.torreypinesgulls.org/2008IHLGF.htm There is some anticipation that there will be a F3K World Championships held in 2009. Confirmation of this will not be known until after the FAI meetings in March. Should this come to pass, the IHLGF will be at the top of the list as one of the qualifier contests for the selection of the USA F3K Team. We had actually decided to change over to the F3K Rules before we knew of a F3K World Championship simply because it just made sense to do so; especially since they are so close to what we have been flying for years. This way, we are all on the same page. By the way, we already have commitments from four pilots from Argentina and four from New Zealand. We look forward to seeing you the first full weekend in June. If I can be of any assistance, please feel free to contact me. Ron Ron Scharck, Co-Chairman IHLGF 2008 Committee 6005 Hidden Valley Rd., Ste. 200 Carlsbad, CA 92011 619-913-4949 [EMAIL PROTECTED]
[RCSE] Clinical trials for cataract and glaucoma topical drug. Hope its real!
Thanks John, This is an appropriate posting for the RCSE, most of us are going to have problems with catarachs due to us looking up at the sky so often. I had one lens replaced after a cataract developed over an 80 day period from none to completely fogged vision...I was lucky because I qualified for the replacement, but most have to live with vision loss that virtually ends the possibility of our hobby. For those of you who have timed for guys who say I can see my model yet you can see it perfectly...I was the same till it happened to me. As it developed I began losing the model for terrifying moments...which led to nightmares and me bolting upright out of a sleep yelling I can't see my plane!...got to the point where the girls would say, Oh your that guy who fly's model sailplanes...versus being governor of NY :-). In any case, this would be better for us than us having radios that didn't need any frequency control...(ouch that one made my gigglehurtz. Good to know that maybe something is possible that doesn't involve a health insurance company deciding our soaring ability future. Thanks John. Gordy In a message dated 3/10/2008 12:09:50 P.M.

Re: [RCSE] How long will 72Mhz remain open?
Since there are so many of us and the FCC has no way of controlling us its unlikely that the band will be closed for many years. I don't know why anyone would want the band anyway since we're only the secondary users, we have to share it with pagers, assisted listening devices and maybe other things I don't know of. (Assisted listening is moving to 430MHz and paging is historic, though.) If we owned the 72MHz band we could move spread spectrum techniques to it but I think we're restricted to our current low bandwidth channels -- operation is not just a matter of frequency but how you use its because adding any kind of data to a carrier occupies spectrum (and the more you add the more space you take up). One interesting prospect is that we'll eventually have a much larger spectrum space opened for generalized mobile applications. This has come about because cramming everyone in this tiny slice of unusable spectrum called the ISM band -- the 2.4GHz band -- has spurred the development of low cost radio technology of a sophistication that was available to only the deepest pockets just a decade ago. The same technology can be used anywhere in the radio spectrum and its one of the arguments Google is using in their quest for slices of spectrum that will be opened up as a result of analog TV shutting down next year. (TV won't disappear from the airwaves, it will go digital but digital transmissions allow a lot more stations to be crammed into a given slice of bandwidth and it also allows the power of the transmitters to be cut to a fraction of what is needed for conventional analog transmissions.) Since we can now share bandwidth with other services without thinking about it we could justly claim to be just another mobile service, just another remote telemetry and control application. This may not come to fruition since the way spectrum is sold off tends to be a resource which is then used as a cash-cow for its owner (which should be us since its our spectrum, the FCC shouldn't have the right to sell off our property like that) but it won't be because of the lack of technology. Martin Usher BTW -- Don't fall into the trap of assuming 2.4GHz is limitless. It just feels that way. RCSE-List facilities provided by Model Airplane News.
