Technical Support / Re: 1090 connection count

I swapped SDR on Rosetta. Still no connections. I removed SD card and reformatted the downloaded latest full software to it.
I refitted card and loaded and configured and then it worked fine with multiple connections and targets.

I assume there was a software issue on the card. I have also ordered a new card to load software in case the card has a fault.

I have also completed the connection of RS232 out to ADS-B on the transponder. I have printed a report for approval.

Thanks for your support

The ADS-B out is disabled at the moment until I confirm it works ok and I get a screen shot from the Jodel showing settings are ok as required by LAA.

To answer the question; Yes, that's how I crosschecked.
The orange against 1090 I was aware of. It just concerned me when one unit was going orange when the other was getting 200 or 300 connections.
I checked the USB slots but not the connection to SDR. I'll do that and also swap them as you suggest.
I had expected that GASL would have seen the Jodel through direct PAW connection.
Thanks, I'll call later.

I have attached config file

I also tested again with GASAL showing 1 aircraft and Jodel PAW showing 21
Also exchanged antennas again with GASAL still very poor

I also noted the neither unit picked up the other directly with pilotaware connection.

ADS-B out is working on transponder and showing co-ordinates when enabled.

Peter, thanks for the quick reply and apologies for the abbreviated version of the issue;
The issue is on a Bulldog, G-ASAL, 4015A4. The PAW is fully installed behind the dash with with remote GPS, Neotech audio amplifier and RS232 out for ADS-B. (HOSTID ending A275 in photos)
The antennas are aviation mono-pole externally mounted on the underside of the aircraft. The 1090 reception as per image was low and at times indicated orange, not receiving any packets.
I had made the same conclusion as you about reception so decided to check the antennas. I removed the PAW from another aircraft- Jodel G-CEIS, 405122. HOSTID A048). This unit is secured on the shelf behind the rear seat and easily removed with remote GPS antenna and centre fed radio antennas fitted to the inside of the cockpit with suckers and velcro.
I placed the Jodel PAW on the seat of the Bulldog plugged the supply into the power socket and stuck the antennas on the screen with the GPS on the cowling. it was receiving as much as 180 packets on each cycle of 1090 with up to 12 targets. I swapped the antenna connection over so the Bulldog was using the Jodel centre feed stuck to the window and the Jodel PAW was using the fully installed Bulldog antenna. The results were the same, still many more packets received on the Jodel and very low on the Bulldog.
Regarding the ground station; I understand your comments but this was just an observation comparing with other local aircraft which I seem to pick up more often at the times I know they are flying. I will get a shot of the configuration later today but in the meantime you may have enough info.

Technical Support / Poor 1090 connection count - resolved by reloading software

I suspected the PAW on one of my aircraft was not connecting to much traffic. I also saw that my PAW grid station at home was not picking up the aircraft much. I have compared the performance against another PAW temporary plugged into the aircraft.
I used the full actual kit belonging to the test unit including the stick on antennas.
The test PAW had around 2000 connections a minute on 1090 and showed 10-12 aircraft. The PAW installed in the aircraft had around 150 connection a minute and 2 aircraft.
I have cross checked the antennas by swapping them around. The results were the same.
What else should I check?
