Hi Fernando,
Yes editing the config files is worth a look, if and when I get the urge :)

All I was thinking was, having a synth TX you could still use older crystal RXs that you might have laying around. That's if you haven't changed over completely yet.

As to stability and frequency accuracy, I would say the synth ones are better.
Crystals vary a lot from one to another.
What they tend to do in production is make a load of crystals and then pick out ones that are within limits for each channel. And sometimes the limits can be rather wide. After all, they have no reason to make the limits narrow as that just means they are throwing away more.
And sometimes the temperature characteristics of crystals is not good either.

As to filtering and interference rejection, naturally the better the frequency accuracy the better matched the TX and RX frequency are going to be, so there will be less tendency to pick up adjacent channels etc.
But generally, what determines the interference rejection is good, preferably double tuned RF stages, good I.F. (Intermediate Frequency) filtering with crystal filters, and double conversion helps a lot giving two opportunities for I.F. filtering, and other techie stuff to do with image response.

Hope that helps :lol:

I like the look of the Corona RXs. Good spec.

Hey Ron,
Leaving the boat in the shed for the season is one thing, but ditching your brown sails icon is too much :( Sailing boats are just gliders on water :P , with variable aerofoils, that sink instead of crashing.
Good luck with the flying, me at the same crack, have a mountain just crying out for a glider. War bird on the way.

Seán :D

Ron:
HiYa Sean,

Wish it was in a shed. It's in a boatyard (costing an arm and a leg) with a big cover over it.
Sorry, her!
And there's jobs like pulling a keel bolt to check it's still in one piece after 48 years :(

Yes perhaps you're right.
The new one is supposed to be a Seaking over the - errr - sea.
But really it's just a shot from X-Plane simulator.

Original icon coming up.

What's the war bird?

The Cockpit SX is, I think, a considerably more powerful tranny than the older MM, and, given its very reasonable price for a Tx, I wouldnt recommend trying to sniff out an old MM.

Ron is right in that many of us have perfectly serviceable crystal recievers lying around, and you wouldn't want to ditch them.  Having a synth Tx just gives you more options, thats all.

I have used my synth SX with the following crystal Rx's with no problem(let's see now :?: ): Hitec electron 6, Jeti something-or -other, various 7 and 9 channel MPX ppm rx's, Schulze Alpha 8's, Futaba 6 and 4ch, Corona's.  The only synth Rx's I've used is the Simprop Scan 7, also works great.  I suspect Corona's are the best news we've had for a long time :D .

Fernando: you can go into your user profile and add in extra stuff such as your name (such as with my profile), without changing your username.  You could also just sign off with your name :roll: !

Ron:
Yes I think it's got to be a Cockpit SX.
Good TX and a very reasonable price.
All I have to do now is find one  :?:
