We used the unit onboard a pleasure craft, powered through USB connection, displayed by open CP 4.0.0, connected to different VHF antennas: the unit cannot receive signal beyond 2 nmiles in this condition it is useless to us
I'm sorry to hear about your disappointment. I agree that 2 NM is below the expected performance. There are several reasons that could limit range, including the possibility of a defective unit. I will reach out to you by email to discuss further.
Was easy to install and wire up. instructions were helpful. is working and showing targets clearly, have not used extensively as yet. will update after a long sailing voyage. shipping was wierd and long. i live in vancouver canada , went from redmond to seattle to los angeles . ??? then to vancouver.
Great unit. infact more than I expected. Worked when plugged into Linux. Service from Tindie and supplier was great just that US Postal Service received on 6 May and it arrived in Australia at my door 30 May. Something must have gone wrong in scheduling. A great pity.
This ist what I'm searching for a long time to use RasPi as a navigation computer or a AIS station to feed web services with position information. I tried a lot of AIS USB devices - but all of them where unstable. One of the biggest problems: the power consumption. Now it works stable with the standard RasPi power supply. The documentation is work in progress - but this was announced. The support via eMail from wegmatt is great and fast.
The product is good , maybe it could be extended by additional offers like the antenna or some pictures about the different connections. Documentation was mentioned that it is still under development. So will be better in the future, but for a Maker should it not be a hurdle. The Communication with tracking number for the shipping is good out of Tindie - the parcel services could improve !
Shipping ( Packaging and wrapping was good and content is well prepared for customs ) is a bit of a challenge : You could track the goods very well on the US side until it reaches your own country. Then it hangs in customs "forever" without any notice. The next message from US could be wrong ( it is in my case ) and you need to use the tracking number for your local official parcel service ( which is in Germany "Post" !) Good is, the product will not be destroyed as it has all needed signs (CE) etc. You just need a lot of patience: 3 days shipping inside US, 3 weeks customs , 1 day in country shipping - the customs is the big dark hole.
Now I am looking forward to my next sail trip to us the AIS Receiver !
Unfortunately I haven't found a way yet to expedite processing by German customs. Most other European countries manage to process packages within a week.
The only workaround seems to be to use DHL or other courier services, which I can quote when requested. But this typically incurs much higher shipping cost (~ $40-50) plus potentially additional service charges on delivery.
