Re: [RCSE] RF Synthesizer
No, synthesizers are not the same as using a crystal, but that doesn't mean you shouldn't use them. Their spectrum may not be quite as clean as a crystal set, but they're still within spec if they're working properly. Synthesizers are tuned just like a crystal set is. dial-a-crash refers to one person having every 72 MHz R/C channel available to him on his transmitter basically at his finger tips. It's just the same if somebody came out to the field with a bag of crystals, one for every channel, just most people don't do that. And so since you have every channel there available to you, this worries some people that careless, selfish, or absent minded people are going to come up on their frequency when they don't properly obtain the frequency. -Charles On Wed, 22 Dec 2004, Thomas Koszuta wrote: But are the RF Synthesizers really the same as using a specifically tuned module and crystal?

Re: [RCSE] RF Synthesizer
But are the RF Synthesizers really the same as using a specifically tuned module and crystal? Names like dial-a-crash and the like come to mind. Software controlled synthesisers (e.g. Multiplex Evo HFM-S) are in principle safer than Xtals. - the UI is designed to prevent accidental changing of frequency. - since the actual frequency is displayed on the LCD screen there can be no confusion. Modules with rotary switches are another matter. Mike RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] RF Synthesizer
But are the RF Synthesizers really the same as using a specifically tuned module and crystal? Names like dial-a-crash and the like come to mind. The Futaba module shown on the Web site is like the Hitec Spectra module -- you alter the frequency using small rotray switches to set the channel number. These switches are (on the Hitect) placed on the back of the module so they're not accessible once the module's put back into the transmitter. When I first got one of these modules I thought that there would be a front panel control for the channel -- dial a crash -- but Hitec had obviously thought this one through. The only concern that I have is those switches. I'm familiar with this type of switch and they're just not designed for frequent adjustment (they're like crystal sockets, BTW). So anything other than occasional adjustment of the channel is likely to make them unreliable. You also have to look closely at the settings -- the slots tend to widen out with use so its very easy to accidentally set the channel to one adjacent to the one you were going for.

RE: [RCSE] RF Synthesizer
I have the hitec, it came my Fut 8AUsuper that I bought from a guy - it works great, just click in the channel on the back. No - I heard that they aren't allowed at contests. I'd consider selling mine, since I just bought 2 Styli' the 8AU won't get that much use anymore. Also would sell my Fut 6 channel if anyone is looking. (I have 3 8 channel radios now) no need for the 6 anymore. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, December 20, 2004 4:17 PM To: [EMAIL PROTECTED] Subject: [RCSE] RF Synthesizer Is there an RF synthesizer that works with the Futaba 9C transmitter (not the 9ZAP)?

Those saying that you can't do it (because of FCC/AMA rules) trying to drown out those who are actually doing it, and vice versa. Does it work? Apparantly. Is it legal? Many say no. The AMA probably could deny a claim based on it, which is probably the biggest concern. [ Yes, I'm talking US here. ] But that's ok ... check 'dis out : http://www2.towerhobbies.com/cgi-bin/wti0001p?I=LXHKB1P=7 Futaba has been promising a synthesized module for a long time, and teasing us with various hints that it might be available. Lately they've been giving dates, but the dates keep getting pushed back. This has been going on for over a year. But this is the first time that it's shown up on Tower as something you can actually order, and the date listed should be within two weeks, so maybe this time it'll actually be available and isn't just vaporware? I wonder if the Berg receivers will work with it? [Berg says that their receivers don't work with Futaba synthesized transmitter, with both Berg and Futaba blaming each other for the reason.] -- Doug McLaren, [EMAIL PROTECTED] If ignorance is bliss, why aren't there more happy people in the world?
