i have owned an rb since early jan with no probs at all.on switching back on, after a two day break, i have suddenly gone from receiving,depending on the time of day,30,40,50+ adsb only contacts in my flights, to virtually none.my polar diagram is virtually non existent,and i only receive a contact if it is over the house.
i have changed the external aerial back to the original twig no improvement.
tried a different usb cable.
re- installed software.
problem remains .rb sma socket is firm,i can only conclude the fault is inside the rb.
considering the rb has suffered no trauma what so ever ,all the above is worrying.any help/advice would be much appreciated.thx david h.

Ive recently had a similar problem, with exactly the same symptoms i.e only get a signal if the aircraft is over the house.

Hi David,
Sounds like something has happened, contact us via the ways in my signature and we will send you details on how to send it back to us.
-
thx James,and airnav support for your replies.i donot feel it is an aerial issue,more a hardware issue,so i am going thru official channels to resolve the problem hopefully.at least the network is ok so i can continue tracking for the moment.
regards,davidh.

David,
I thought one could not receive network aircraft if the box was not functioning. Do you have lights flashing on the front of your RB? How many messages/sec are being shown at the bottom of the screen?

If the software can see the RadarBox connected it allows the network, otherwise those people in areas where there is little traffic or none at night would be booted of the network and they wouldn't be pleased :)
-
Booted off the Network! Poor choice of words from a commercial operation regarding customers.

Thats why there is smiley face, it obviously doesn't happen.
-
Sorry, don't normally see a smiley from you. I thought it was a typing error. :o) Still, my statement stands.
As for the user's problem - I'm sure we would all like to know what problem the box can develop after just sitting around for a while.
-
I seem to have the very same problem. Any ideas what could be the cause ?

Have you checked to make sure that the centre pin of the antenna plug has not been pushed back into the plug body?
Have you tried a different antenna?

I also have had a similar problem for a long time now. Switched on one day and reception right down. Compared with an sbs-1 running along side. All fine there, so guessed it was a problem with the radarbox. It is nothing to do with antenna or usb connections. The Radarbox is the second one i have had. The first had a problem with the usb connection. Have yet to approach Airnav/dealer about repair or replacement.

I'm surprised you haven't bothered to get a replacement. I'd be onto this straight way, especially with the no-quibble guarantee that AirNav provide - as long as you haven't taken the box apart :-)

The antenna plug looks as it should be. And yes, I have tried another antenna but with the same result.

Well, in that case I would contact Support direct at [email protected]
-
Actually, I bought the unit through a local agent. I have already contacted him and he agreed that he will replace the unit. Still, it's a mystery to me what could be the problem. When also looking at another post there are more people with this strange behaviour of the unit :-(

Doesn't really matter what the problem is, if you are getting a replacement box :-)

thx gentlemen,i feel it is a hardware problem within the decoding area of the rb,i still see the odd aircraft directly overhead,my external aerial was pulling in adsb onlycontacts from the wash, to irish sea,to the channel.will keep you informed.regards,davidh.

David,
I think you are on to something. I too only received some nearby adsb contacts with my own unit. I just connected another hardware unit which I now have on loan from the local agent, and WHOW: 185 airliner contacts up to 200 NM away ! My own unit is on its way to Airnav, I hope they find out what is wrong with it.

I too am now seeing this problem.
I have emailed support ( Today ) and am awaiting a reply but why are there so many getting similar faults all of a sudden?
Anyway, looking forward to getting it fixed now Viking9 has shown me how to use it properly :-)
-
Gentlemen, I believe there to be a fault in the front end of the rb,eg, where it receives the data from the antenna,i am parcelling it up this weekend to send it back for service/ repair. Please see my polar diagrams, the most recent one is rather truncated I think you will agree.
sincerely,davidh.

Hi David, I've found that range and reception is extremely weather dependent - high pressure and clear skies - very good range, misty, cloudy, rainy low pressure - range much diminished. Anyone else find this? I thought mine was going deaf, but then it started going berserk again - could it be routing is drastically altered by weather patterns?
-
Hi CoastGuardJon,
My problem is certainly not weather initiated> I was at an airfield reently with another user in the car next to me. I was seeing 12 aircraft, he was seeing numbers in the hundreds.
We had exactley the same kit.
Thanks
