Update on my transmitter. It looked OK but wouldn't boot up properly. So when I got it back from Sean I sent it off to the Multiplex service agent David Leigh in Adelaide. He had a look and unfortunately the main board has some corrosion on it and he couldn't repair it. Darn. The memories are stored on the board so all my hours (days?? ) of programming are lost too. Double darn.
He was able to supply a replacement transmitter for a fairly good price, so I've accepted that and it should turn up later this week.
I relayed to him the story of the mobile phone interference and he said that a mobile can put out 6 watts of power. He said that Multiplex has tested the SX in a field interference test at Stuttgart and it exceeds the industry standard for all bands of interference, but the effect of a close-by mobile phone would exceed the industry standard. So he was not at all suprised that it had become locked out, and agreed that holding it next to the Tx when it was on a call could certainly have damaged it.
The new software version installed in the new one has a "recover" function which apparently helps to avoid a known problem where interference can affect programming.

I got my new transmitter. Quick test - interestingly, when I did a mobile phone test, calling from one mobile to another, about a foot from the Tx, it blocked it entirely again. So it's not a fault with the previous Tx. It does it with the new one too. Weird that there's a history of NOT getting interference - maybe they've changed something with the GSM network. I dunno. I don't really understand.

Andrew,
The frequencies are as follows for Aussie GSM. 900 MHz primarily for old GSM, with some 1800 MHz for infill. A phone with 1800 MHz but no 900 MHz may not even be able to register.
It doesn't make sense. I think there is some problem with the design of your equipment.

A buddy-cord klutz story from today:
While training my son on my Duck, I brought it in for a semi-forced landing, then passed my Tx to my son while I went to retrieve the Duck. Both our transmitters were still connected by the buddy cord.
I got back with the Duck, got the Tx back from my son, and launched it, gave it the usual down elev at launch to avoid it going backwards. It dived a bit more than usual, but I pulled back, it recovered a bit unsteadily, then seemed to go left, then settled into a steady pattern, then my son yelled, "We've got the wrong transmitters!"
So HE had the master and I had the slave, and HE'd been controlling the launch recovery! We clumsily swapped Tx's, with the cord getting in the way, then settled into the normal pattern, thinking how lucky we'd been that it all worked out. I was impressed how he'd flown the launch - he didn't actually know that he had control at that point, but was going through the motions of how he'd seen me fly the launch stage.
Apart from that, today we had one tree recovery, left the car unlocked, and dropped a Hitec crystal inside my JR Tx. And a broken battery hatch on a Tx. That's enough klutzing for one day.

I have to add to my list. Can't keep up with the number of klutzy things I do.
1) last weekend flying with Mark and Knoxie at SC, the Ozprey was really on song. Since I now I have a NextG phone which doesn't conflict with my MPX SX radio, I had it in my pocket when I got a call, so flipped it out. "Hello??" says VAnders as I try to click it onto speaker phone. Darn, why won't it go onto speakerphone?? Push the button again - hey where's the Osprey - Aaargh, pull full up but it plunges in for a swim about 10 metres into the waves. It finally caught a wave into the shore, feeling a coupla hundred grams heavier, and with the LMA bleeping in a sick drowning manner.
It's been rinsed and left in the sun for a few days, but is still in the shed and I haven't tried it out again yet!
2) DSing the Nemesis at Dayboro yesterday, it was very thrilling and I kept pushing it hard for a long time. Nobody else there to take turns, so I kept hammering at it. Along the way I increased the elevator rates quite a bit and it was snapping tight paperclip turns. Finally decided that the brain was well and truly fading so it was time to head home. I'd done a few really soft landings already, but I didn't mentally click that the changed rates would upset the elevator compensation for landing with flaps. So I did the usual approach and when I pulled flaps it pitched down. "lucky to get out of that turbulence" I thought. Next approach same thing happened but I landed - too fast and too steep, and into the weeds at the far end of the runway. But unfortunately the weeds were more like small trees now so I have a big repair job (again!).

I think I'm beginning to see some sort of pattern involving Thevon, mobile phones, and crashes. Has anybody else noticed a pattern? I'm thinking, just as a precaution, that anyone who flies with a mobile phone in their pocket should make sure there's no Andrew around, because when the set is complete bad things happen.

That's terribly, Ding.
(Is Andrew's phone number available online? Not yet? Wait till the word gets out.)

You won't have to worry - I'm running out of planes so fast it won't be an issue!

That would make a good mock TV commercial.
"Are you sick of your glider? are you getting sick of repairing every little scratch to the wings and fuse? Is your girlfriend/wife/ (boyfriend if your into that) complaining that you spend too much time with your planes? Call dial-a-crash 1800 666 crash we'll will put a little satan in your hands! Conditions apply : thevon may be busy at time of calling so please leave a message."

This isn't a klutz story more like a needless act of random stupidity. when i was about 14 i was given a large balsa pylon flyer and wanted to make it fly, so i threw it a couple of times but decided that that was boring so after crashing it in the bushes etc. I decided to make it look like a real crash so i found some petrol and filled the fuel tank up with it and poured petrol all over the engine cowling and cockpit lit it and threw it looked cool to me at the time but if I saw me doing it now I would give myself a good ass kicking! I still can't understand why I did it I guess I was just a 8==D
