Old Koreelah

Can you make that a red spandex outfit Old Koreelah so we can spot you straight away ????...............

Obviously a gal enjoy her job...............will we have some like her at Temora ????.....................

Just another thought, I removed thr PPT from the stick on my Gazelle to the panel next to the throtle.Gazelle owners will know what I meen lifting ones leg over the stick ment some times knocking that little red button off.

Once removed all good as ones hand is most times on or near the throtle.

Inside the original big ugly PTT switch I found two tiny microswitches mounted side by side. I think I can embed them in the top of the stick and have a floating brass plate to cover the pair of plastic contacts simultaneously. Then, after passing the wire through the stick I can re-solder the original wires back together again.

The only problem remaining is the interference noise when transmitting. A mate has some Ferrite Voltage Spike Protectors/Noise Suppressors in a hinged plastic case, (as suggested here) so I can do some testing with them.

Thanks everyone for the detailed replies and I'll report on results later.

The Yaesu needs to be slightly longer... I filed away a small metal step at the base of the plug to allow the plug to reach further into the socket.

This could solve the problem of my having go hold the plug in as I press the transmit switch.

The original switch would have been switching two circuits, (PTT and mic audio). You will have to duplicate that. The single circuit switch may not do the job. If it was a normal panel mount radio, I could guide you through it but I'm not familiar with the Vertex hand held radio so I can't help you there. Maybe Vertex have something in their accessory list you could use. John.

Food for thought.

You can get clip on ones http://www.jaycar.com.au/productView.asp?ID=LF1294&keywords=ferrite&form=KEYWORDthey are a lot bigger generally but you can put a wrap in the line and run the wire through twice.

Beyond the noise is the head set working... can you hear and talk with it?

 

Photos might help us resolve the issue

Have you any ideas what exactly would have caused the noise?

Two pix: original PTT, and the current setup, with new PTT at top of pic.

Is there not a wiring diagram for the plane? Either with the plane or on the manufacturers website?

The problem is how to replace a 4-terminal switch with a tiny 2- terminal PTT switch. Neither the Vertex radio or the after-market PTT has a wiring diagram which can help.

After doing my best with the info I could obtain, it appears I may have damaged the radio. (The noise sounds like feedback, but only happens when the headset is connected. Fitting a different headset does not remove the noise, no does adjusting the volume or removing the headset from proximity to the radio.

Thanks for the suggestion and links, Tex. Is it possible to install ferrite rings without having to cut off and reattach plugs?

Sorry to bug you again, people, but I really need a hand with my radio...

You may remember I recently asked for advice re wiring up a PTT switch on the stick.

After reading all the advice offered, and testing the cut-off original PTT switch, I tested my plan by carefully touching together the two pairs of wires that the original switch connected. The radio worked OK so I joined one pair of wires and soldered the other through the switch.

I now get a loud tone whenever the PTT switch was pressed. This happens even when the PTT circuit is removed from the radio and only the headset is connected via the 3.5mm plug.

Just to complicate the issue, the tone does not occur when the radio is operated without the headset.

What have I damaged and how can I fix it?

Regards,

Lyle

Ok...im arriving Wednesday and leaving Sunday. We need to catch up!

No matter how much time you have in aviation have there are occasions when you have to put every thing you have into the situation that presents itself to you. You never reach a state where you can sit back and relax. Never.. There is always something that will challenge you. Totally and completely Nev

In response to OME's landing issues, the landing phase, and particularly late final, is my favourite part. Does this mean I don't actually like flying and want to get back on the ground, or is skimming the ground the big thrill?

I am still in the training phase and landings cause relatively more adrenaline to flow for me as well.What about the take off roll? How much adrenaline would have flowed in the pilot's veins during this take off? You'll need to watch full screen to fully appreciate this take off:

 

Thanks for the thoughtful replies, comrades. In the short term I'll go with Moz's stick position as a stall warning. In the medium term I'll perhaps get help to design an electronic system, but the long-term fix is to redesign the wing to improve slow-speed performance so that the stall is less likely to sneak up on me.

I hope to increase wing area and incorporate the leading edge profile of the later D18, which is reported to handle better at slow speed. Adding slotted flaps should make a huge difference, and bring stall speed back to respectable territory.

Hi RalphA while back I was hunting up how to build an AOA indicator, not sure I'd actually build one, curiosity as much as anything. Couldn't find anything on the net at the time. Came up with a few ideas of my own, vane with optical sensors, 2 ports above and below the LE with some sort of electronic pressure sensor(s) to give the differential etc.

 

Do you have any specifics or references on how to build/calibrate ?

 

Ta Mark

I like the simple pressure-tube type, but I have a specific reason for needing an electronic version. An audible tone (like sailplane drivers hear from their variometers) would be even better.

Lyle

Thanks for answering a question many of us were too afraid to ask...

...I could definitely see myself getting used to the nice hot days you guys have.

Everyone should try this, for safety's sake.

Some old sayings have lost their meaning through over-use. That was a real close shave.

I actually find big radials more dangerous even when they are not running. anyone ever see a radial flick a blade with no one near it?

Thanks for the prompt and inspirational replies, folks!.

I will pass these on to the gentleman himself.

I know a bloke who would love to learn to fly, but he has an arm missing.

He has made enquiries but was told he'd have to pay for a plane to be modified...

Does anyone know of somewhere with the facilities/equipment to cater for him?

I presume an aircraft without flaps would be a good start.

... awareness of subtle changes that have occurred in regs and ops ; for example,in flight above 5000' requirements and general CTA avoidance and what we can ask for/can't ask for and what boundary tolerances we need to observe...?

Some blokes say we should keep off the airwaves when you go above 5000'. Others say we should report to WLB or BNE centre. If we don't carry a transponder it seems like the right thing to do, so that the controllers know who that unidentified blip is, and where he's going.

If we RAA aircraft cause significant stress to the controllers, there may be pressure for us all to invest in transponders.

Weren't they coming from Townsville?

My information is that they were a degree or so off course and overshot Amberley before encountering the mountains.

If you go Tomo's way.You can see the wreckage of a Avro Lincoln that crash on top of it (Mt Superbus).Its a bit hard to spot though.If the sun is in the right place.You will get a reflection of the wreckage.

Hi All my name is Peter , well where do I start , I have been an aeroplane since .... well birth I guess haha , I am 57 years young and have decieded to start a project I should have started 25 years ago ( got married had kids , life, you know the story ) . I have started to build a single seat all aluminium aeroplane from plans and parts supplied , this aircraft is normally powered with a modified VW engine ,I am giong to use a subaru EA82T engine , I would love to hear from anyone who is building one or simmilar or anyone for that matter ,

Tell us a little more about your project, such as the aircraft type, and where you are.

Lyle

Wasn't sure which section of TAA to put this in, but shift it if you feel necessary, Glenn.Coming up this weekend, Sunday the 19th will be 70 years since the first bombing raid took place - 243 killed.

 

Over the next 18 months there were another 63 raids, with around 40 more added to the toll.

 

Spare a moment's quiet contemplation this Sunday.

Obviously a submarine, it resembles none of the many Japanese midget sub designs I have seen.

I wonder what it was and what became of it?
