We just had thunderstorm this afternoon. When I've got home, my RB range reduces to less than 20nm where I normally get around 200nm.
Hope it is from wet coax not circuit damage.
In the mean time, apologize for limited range around Bangkok.

Doesn't sound good Kenny.

Good luck, Kenny
Hope it does dry out OK.

Kenny,
Suppose it's a bit late now to tell you but ALWAYS pull out the antenna connection if thunderstorms are forecast to be in the area.

Lightning arresters are available, but I'm not sure just how effective they are in protecting RBs, they seem to work OK for GC Receivers though.
-
About arresters: They work quite well for secondary lightning discharges or strong electrostatic charges, that are build up shortly before lightning strikes*. During this effects of thunderstorms you can sometimes already smell the ozon, but you don't get the full hit. If you catch a full hit (primary lightning discharge) they are useless as all equipment between lightning entry poitn and ground/erth gets fried. I've some experience with satellite equipment and terestrial TV and lightning causing electronic toast.
* The flash-channel starts building up, but the channel building up from your antenna isn't the one that does ignite through.
Kenny, I hope that it is just a drowned Coax connection.

Just an update.
Swap RB with DVB-T dongle and run RTL1090, the Msgs/Sec jumps from around 15 to 150 and see a whole lots aircraft.

Ingo, thanks for the extra info.

Hi,
I will be offline for sometime until it is come back from repair. During this time I'll using DVB-T dongle and RTL1090. For sure, I'll miss the RB interface.

Hi Kenny,
Thanks for the update, missing your input, I hope it is a quick turn round. Are you able to input into the network with the dongle?

Kenny, see PM

Contact support and they gave the link for client download. Asked to give them the Sharing ID once installed to activate the account. ID & email sent several days. Still quiet.
Kenny

I will get on to them Kenny.
Alan

They emailed asking me to fill the form in Add Coverage section of RB24 so did I. That was 5 days ago.. My feeder account still not activated.
In the mean time my RB has arrived Waters & Stanton. Let see how soon I get the repaired RB back.

Hi Kenny,
Thanks for the update, have emailed them again
Alan

Hi,
I just received my radar-box back from Waters & Stanton after it went very deaf.
I am now only getting about half what I was receiving before.
I wonder if its the Saw filter that's the problem something is definitely limiting my signal as I could see SE for 200nm before
Not happy!!

I would get back on to Waters and Stanton, they should have checked it was working OK before they dispatched it to you.
Alan

Hi Alan,
On the invoice it said Checked and working OK .
At this moment I can not see any aircraft over the North Sea as before i could read SAS for a long time before timing out and I used to see right down from Leeds to almost the Dutch coast.
Although it 's a little better than when I sent it in it took them 3 weeks to do and had to ring twice about the progress mmm.
And of course all of this is costing money.
Rant over
Thanks Alan

Until now haven't heard from both AirNav or Waters and Stanton since I sent the box on May 14. AirNav support hasn't reply my mail either. Should I worry?
BTW My share client account still hasn't been activated. I wouldn't worry about this.
Kenny

Hi Kenny,
I keep waiting to see the returns from Bangkok. I have emailed support and am waiting on a reply.
I would suggest you contact Waters and Stanton by email to find out mailto: [email protected]
Alan

Finally, I've got the box back from post office.
Kenny
-
Lovely to see Bangkok back on the air Kenny.
Alan

Welcome back Kenny!

Hi Kenny,
Ditto, just in time for the monsoons? Just a thought, did W&S list the fault or replaced components? I've just noticed that the clock time in here is GMT -1, what's that, Central European time? I'd've expected UTC Z - GMT time to be used for an application like this.
I ought to take the AOR AR8000 off my profile, it was lifted when I was in Weybridge and London in June/July - anyone got one they'd like to sell me?

Hi CoastGuardJon,
The repair log they told me was:
"Replaced F1 and added a resistor modification to help reduce chance of damage to SAW filter. Tested ok."

Kanok

Hi Kanok,
"Replaced F1 and added a resistor modification to help reduce chance of damage to SAW filter. Tested ok."
Not quite the classic repair - "SAW filter replaced" - good to have you back with us! How are you finding the sensitivity now, any reduction in range, although of course, that could be due to weather conditions or A/C not flying as high etc..
-
Hi CostGuardJon,
The RB still building a new polar plot. But from what I see it is quite similar to the one before repair. I may have to compare the screen capture after it has enough plot.
Kenny.
-
Hi CoastGuardJon,
The reception after repair is quite similar to the one before..
Kenny
-
Kenny, you could do with a d/b update to receive the BKP aircraft which is showing on your logs as unknown.
Alan
-
Hi Alan,
Did the full update when I reinstall the RB.. Don't know why it miss that..
Do the full update again, this time it is OK..
Thanks,
Kenny

Hi Kenny,
A new Navdata is produced each day to include any added, deleted and amended records from when the last one was produced. The BKP will have been added to the Navdata since the last one you downloaded.
