SAJ, I’ve got 4 rims. Steel split rims with nuts and bolts and reinforcing plates for 3 of them. Other one is missing inside bolts. Three of them are fitted with Trelleburg tyres (one still new) . Still all got tubes in them which must be good as they’ve stayed up for a couple of years. Last one has Kenda tyre in very good condition. All tyre sizes are 13x5 x 6. is that the right size for yours? Someone said you need small wheels? Anyway, give me a call on 0400004011 if interested. cheers, Jenny

Added it to my Home Screen too!

Admin, this is great! First time I’ve seen it. thank you

They came off my SP500.

I’ll check out back tomorrow, pretty sure we’ve still got them

Did you get any rims or still wanted? I may still have a set jenny

Check it out before you give it back to the owner. 🤣🤣🫢

Yes, using the Trig. I’ve got the sidetone set in the middle, perhaps I’ll play around with it a bit and see if it makes a difference. Didn’t think of that

I’m really happy today!! The wiring we did actually works! It was as you said, incorrect wire going to instrument bus bar instead of battery. We changed that around and put in the inline fuse. Went for a fly yesterday and about 80% fixed. We can both hear each other, hear transmissions and others can hear us. There is still a slight problem , when I transmit I can’t hear myself speaking and my passenger also can’t hear the transmission. When he makes a call it’s the same for me, I can’t hear what he’s transmitting. I’ve still got to get the relay put in, too. But basically my radio problem is sorted, I can live with the rest for a while. Just wanted to say thankyou to everyone who gave advice and supported me. RFGuy, I’d still love to drop in to Cowra sometime and meet you. Happy flying everyone😀

So do you think the damage might already be done with the voltages being so high? Is it likely this crowbar effect will continue even once earthing and fuses are fixed?

It’s a SP500, 19-3346. We intend using diagram 1. We can do the fuses and check earthing. There is a guy who is good at avionics who is willing to check our work and put in the relay, but he’s on holidays till Nov. He’s the guy who had the VSWR meter and checked the voltages against his machine. The radio sounds great on the ground, but in the air under power, you just get noise and no radio. Initially when I first flew it home to Benalla, there was SO much static and screeching in my ears that I took the headphones off! Had such a headache when I got home. Found out a cheap USB plug causing a lot of that, and since then we just keep finding other faults.

Funny how this all started by a radio issue that has been stumping us for a month. Along the way we’ve found and fixed quite a few other possible wiring problems. Earth wires not connected, intercom not connected, pilots headphone Jack needed replacing, no earthing on either headphone jacks, pins missing and in incorrect places on radio install, no fuse on radio. These were all on the inside of the firewall (cabin side). They all needed fixing, or would still be possible causes of interference and noise. Hopefully once we fix wiring and earthing issues in front of the firewall I will have a safe and functional aircraft and a radio that works. The help and suggestions and advice that I’ve got from everyone here has been phenomenal! Everyone’s busy , but so many people have spent the time to help me get this radio issue sorted. Can’t thank you all enough! if any of you ever fly to Mansfield, lunch is on me!

You’re a good nan, Glen! THAT makes it much easier!

This is photo taken a few weeks ago, doesn’t show the regulator. Note there is no yellow wire going to the battery. Is the thing on the firewall the main bus? Is that where the isolator should go? The red power wire from the regulator is where I’m guessing the 20 amp fuse should go. Does it matter where along the wire it needs to go? Ie close to battery, or close or regulator? Does it matter?

Ok, so I’ve got the fuses and relay. I could only get 5 amp blade fuse, not 1 amp. Tomorrow Shane and I will do the following: 1 put the yellow wire from the regulator direct to positive on battery 2 ensure the earth wire is connected to engine block or the negative on the battery. We still need to determine where the 20amp fuse needs to go and the isolator. I have some wiring diagrams downloaded that may help. We will get these first two parts done anyway, and ask around the gliding people and see if anyone can help during the week! Hopefully this is where most of the interference has been coming from. Thanks again
