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?
