Have been working on the Prado this weekend and one thing I’ve not looked at for awhile is the antenna for the hf radio. I’ve cleaned all the earth points but was wondering if anyone has opened up a 910 ? Are there any serviceable parts?

I reckon the earthing is very important to get right so if thats ok and its working ok there is no need to go any deeper.

I recently installed my Barrett 2050 and 910 into our new car and rang them to see if it needed servicing or any firmware updates or the like and he said not to worry about anything unless it stopped working or started to perform badly.

Unless of course you are a tech or something and are fully comfortable with that kind of thing.

No way I would be opening it up anyway.

Have you used it recently?

The last time was July last year on the David Carnegie track . On closer inspection I’ve found some corrosion in a connection on the aerial lead so have cut that out and hard wired it , will check tonight if the skeds are still going. Decided not to open it up! Thanks.

Barrett have a R and R service if the transmitter or antenna are playing up.
Nothing serviceable inside, the earlier cases didn't have a breathing valve so can suffer from condensation inside in various circumstances.

Barrett have great after sales support ,if you contact them they will give you the contact details of a technician that will assist you.

I have a barrett 950 with a 2019 auto tune.

Are you a member of one of the networks ? Members there would also assist.

Let “sleeping dogs” lay ! There is a full length printed circuit board inside with hoards of ‘gizmos’ on it, plus multiple electrical relays that employ different antenna wire lengths (for the range of frequencies available). Mine is a blue model...the break apart point has an O ring for water sealing. I did need mine repaired once...as mentioned above, Barrett can point to your nearest approved repairer, should the need arise.

I have repaired quite a few things that people thought it may "be interesting to see inside".

Lyncol.
Although different concept of working but if you have seen a telecom/ Telstra street terminal it it might seem similar. ie, lots of wires. Apart from "seeing" you may not learn anything if you don't already know what is inside an autotune aerial.

Allan. B and RMD, thanks for your replies, my father told me when I was about 10 that anyone can pull something apart but only a few can put it back together again and make it work(he was a 1913 model !) I’ve always remembered that in my profession and so far has served me well. ...................................... It would still be good to have a look inside.

Lyncol, it may not be looking into the real thing but here is a video of a 910 internals.
Hope it helps your curiosity.
Cheers

Then unit is micro processor controlled, lots of relays inside that can cause issues.

I pulled my unit down when it went faulty ie wouldn't tune, started off doing it very occasionally and gradually got worse.

If you can hear it try and tune then also check RF cable, if you can't here it try and tune check control cable and RF cable. Barrett tech said relays or bad earthing most likely, earthing was good on my unit so most likely a relay.

I pondered replacing them ( replace the lot if one is faulty) but as the case had some cracking decided for reliability to replace the unit with a new one. That was the next problem, new units are very big, to tall for me to be able to get car into the garage so asked Barrett if they could make me up a new old unit which they did. Once installed no more issues.

I have the Barrett 2019 Autotune with a Barrett 2050, last year I noticed hairline cracks in the housing and decided to disassemble the antenna and inspect. As suspected the cracks caused water to suck in to the housing due to expansion and contraction especially after some heavy rain.
On disassembly a good deal of water came out and I was shocked that the antenna had still been working perfectly.

For everyone who really wants to know what is inside I have added some photos.
