Second spektrum satellite

[vtrnutter]

Does anyone know if it is possible to add more than one satellite receiver to a 2.4 spektrum system to further improve signal reception?

Thanks

Yeah,

There's a few Spektrum RX's that have this functionaility, However you're talking big bucks.

AR9110 9-Channel DSMX PowerSafe Receiver (SPMAR9110): Spektrum - The Leader in Spread Spectrum Technology

for example.

If the rx has a second or third satellite socket yes it is. Rx's like the 7100 7100R 9100 etc

Ok, I found this. Anyone know anything about it?

Haven't seen that before and it's an interesting idea but one downside is that even though you can have multiple satellites, they will all still be connected to the receiver via a single relatively fragile cable so you don't have as much redundancy as with one of the high end Spektrum receivers that have multiple satellite connections.

Placement of the Rx & sat is more important than having mulitple sats mate.. from what I recall from a previous thread.. the right hand aerial is the main receptor (when wires are pointing down)

Heres the thread with more info mate http://www.rcheliaddict.co.uk/spektr...liability.html

Ps. Just replied to you on Ebay.. dont forget your thrust bearings and feathering shaft sleeve on that head!

it's a bad idea because it will deteriorate the reliability.
Actually losing the RF signal is very very very very very unlikely in a small model (because it doesn't shadow the RF signal, and because you're flying close).

Rubbing through a satellite wire that will then shut down your receiver is quite likely and even more so if you have more satellite wires.

"Loss of signal" is usually the same kind of voodoo explanation as "static", unexplained problems that are given an arbitrary explanation.
I've had the majority of my Spektrum lockouts (of which I've seen a few) with two satellites. A dodgy satellite is one possible cause (it's proven to be dodgy, but I can't prove that it caused the crash).

Oi..!

Static is a problem in some configurations, and can provoke lock-outs, RX re-boots, etc. Or, at least, it appears to be - I had a heli that went from unflyably unreliable to 100% reliable just by applying graphite paste to the tail belt.

It was either static or RX pixies...

i always ensure i have the active (left hand side) wire on the spektrum remote in free air and not by any carbon parts and touch wood this has always worked for me ;0) the ground wire can be over carbon parts and is not a problem (the side the plug is on)

>> Static is a problem
well, "usually", as in the majority of reported issues.
Of course, static can happen. If the heli is spitting ball-lighting, I won't argue. The same with RF interference - let's fly in front of a 850 MHz GSM basestation, and I believe even the toughest satellite will hear nothing but RF pixies exulting on the third harmonic

There's a valid point there.

I had a horrendous problem with a little GAUI some years back, and blitzing tail belt static made it completely go away. I guess this has left me a bit prone to making static my first guess if I get Spektrum LEDs flashing - which might not be as good a guess as it was with the GAUI.

I hate the whole radio voodoo mind-set - I'd much rather approach it analytically. The trouble is that it's hard to gather good data, and reliably pin things down

yea so do I. I design radio chipsets for a living... doesn't help one bit.
I had another "Spektrum lockout" only two weeks ago. Belt-driven, might have been static. Might have been the ESC. Might have been a stray electron from cosmic radiation or a pixie or two
