Author Topic: I can see other traffic but my the Vector chart shows no broadcasts -STILL BROKE  (Read 2723 times)

FlyingPastor

When I am flying my SkyDemon, hooked to PAW Classic, shows me lots of other traffic. However, when I look at the vector chart and select PilotAware, it is apparent my unit stopped transmitting before the last licence change (and I did a software update then). I can see my ADSB just fine (trig transponder), but I can't see any Pilotaware transmissions.

Hex code is 407F92

And yes, I've checked the licence date is 2025 :) Although I assume if it wasn't it wouldn't be showing me traffic in any event.

PAW isn't receiving data via a mobile phone as I had my hotspot turned off. So the only reception is through the PilotAware aerial.

In settings, check the setting for transmitting PAW has not become some silly speed.

In settings, check what your ICAO code is, it sometimes gets reset on software updates.

If the setting is not correct, write down the wrong setting before correcting it.

Check the incorrect ICAO code in Vector and see if it matches your flights.

Next time you fly, check for the corrected ICAO code.

Thank you, both for the rapid response and its helpfulness. The issue was the Hex ID, so turns out I'm transmitting well. All fixed now :)

Ok, so I made a silly assumption, still need help.

1. The suggested fix appeared correct, the Hex-ID was wrong and when I checked the incorrect Hex-ID I could see my previous flights.
2. I changed to the correct Hex-ID (407F92) and assumed all would be well ...

but it turns out that despite having 407F92 as the Hex-ID and 0kts as the aircraft transmit speed, my PAW still doesn't broadcast on PilotAware (but I can see all my ADSB transmissions). On SkyDemon I can see traffic, and on the PAW radar screen I can see traffic.

What am I missing (its a classic PAW and must be 7 years old or so)

Double check the number has remained correctly entered and the licence is current?

FlyingPastor

I have done ...

I see the diagram here

You have selected "all" transmission types, I have a transponder. If you just chose PAW as the transmission type it looks very different :(

I agree it looks very different.
Can you describe your setup

1. What type of antenna are you using ?
2. Where is the unit located (if antenna attached to unit)
3. Where are the antenna located (if antenna are remote)
4. What type of aircraft construction, metal, wood ... ?

thx

1. What type of antenna are you using ? - PAW External aerials
2. Where is the unit located (if antenna attached to unit)
3. Where are the antenna located (if antenna are remote) - antennas are below the aircraft with sticky sheet metal backplane
4. What type of aircraft construction, metal, wood ... ? - fibreglass

It was working exactly as set up until the latest software update as you'll see from the initial posts. That update changed the HexID but I didn't notice as SkyDemon still showed all traffic. It was only when I replaced a damaged aerial and I checked the vector chart that I realised it hadn't been transmitting for a while. I can still receive traffic.

Slightly bemused!

Damaged aerial? Do we think the transmitter side of the radio module could have croaked?

FlyingPastor

Which radio is it? I’ve got a PAW classic, the USB radio was replaced a couple of months ago, the one inside the case (which I assume is on the Pi circuit board) hasn’t been (and I don’t know if it can be)

FlyingPastor

I should add both aerials are new and bought from Pilotaware

There's a radio bridge inside the case, last time I looked or fixed one, it was a separate daughter board. If faulty, and it's a big if, it can be replaced. Be wary of static when replacing, if this doesn't mean anything, leave well alone.

The radio bridge is a transceiver. A damaged aerial can result in reflected power back from a mistermination causing a problem in the output stage of the transmitter. This is a bit techie, I know, but that's just how it is...

The "USB radio" is an SDR and does 1090MHz for ADS-B and mode S

If damage has occurred to a transmitter stage, replacing the aerial doesn't fix that.

The aerial connector on the radio bridge board can also break where it joins the PCB. I’ve repaired a few of those over the years. If you receive PAW transmissions OK then that won’t be the issue. If you only see non PAW traffic on your display, could be a connector issue.
