Thanks Richard - saves me failing to find a solution. PS LORA is on the back burner - literally as we have no heating and the next network problem involves radiators and pipes…

I’m wary of modern chargers, I’ve used Samsung phones for years and have a variety of 5v and higher voltage chargers. Supposedly the newer, high voltage (‘fast’ and ‘super fast’) chargers are smart and can increase the voltage, and hence watts, as required by the device being charged. I usually try to use ‘dumb’ chargers for anything other than a phone as I once accidentally plugged my MP3 player into my Samsung fast charger and it got fried 
The Samsung 5v and Samsung Fast charger bricks look the same, apart from embossed lettering which can be hard to see. The Samsung Super Fast charger uses USB-C so it’s easy to identify.
Just be cautious if using a ‘smart’ charger is my advice.

Were having some real trouble getting M1CVL-1 to receive any packets, we have tested all the connections and they are good, the frequencies are right, its transmitting as we have listened on a hand held… but we are missing something, somewhere!
Is there any chance someone could post the basic settings needed to get it theoretically working right?? stuff like the Baud rate, and receiver settings ETC… Thanks!

I’m NOT an expert(!) but I have done some screen shots from my igate which is working - well at least it works with my tracker!
I should say feedback (Not the horrible RF PA destroying type) is welcome!

Thanks for that, i have forwarded them too him, and see what he says!

It is, but seems to be struggling for reception range, he had it on his colinear and his location is a local high spot… something fishy going on… ive suggested a new ipex patch lead, see what happens! In other news, my board should arrive today so i can get mine done!
Thanks

It may worth setting up the syslog or using a public syslog like the one that I posted earlier in this thread. Packets can get filtered out by APRS if they are received by multiple stations. The syslog shows all activity and so very useful for diagnosing igate problems.

When you put the Board into “flash mode” by pressing the menu botton and clicking the reset button, should the display say something?? mine just goes blankl! im sure my tracker displayed something like “FLASH MODE” on the screen…
Thanks!

its not a recording issue, the screen hasnt displayed any received stations either… ive drove past it 4 times today, first time at just after 0500 i had the tracker connected to the dual bander on the roof of my car, and it picked me up! the other 3 passes were in a vehicle with the tracker in the windscreen, and it failed to pick me up… infact nothing picked me up… he’s trying another board out this evening I think… see if its a faulty board!
Thanks

I posted a request on Github and Ricardo’s answer was very quick:
He will try to implement the feature in one of the upcoming releases …

EDIT now on a Jpole antenna, hung under my bedroom window! see how it performs… if its all good, ill mount the Jpole higher and a bit more permanantly!

Hi James,
Thanks for this info, very useful. I have just placed my order, as I would also like to set up an iGate here at home.
My total price was just under £38 delivered:

Ordered mine today as well. Delivery in just two weeks which suggests it might be coming by air I think.

Shows quite a bit of activity relayed via G3CWI-13 or M0XZS-2, and more than a few bits of garbled (CRC-ERROR) data as well as direct GPS positions. Only a fraction will show up on APRS dot fi.

Ok, im using the logging thingy at https://lora-aprs.live/ It quite often shows a “CRC ERROR” what is that? Is it just missing date due to bad transmission/reception? or is it something else??
Thanks!
Alan

A CRC error suggests it received a signal but part of it was missing or garbled. If it’s receiving some signals correctly then I don’t think there is a problem. There are bound to be weak signals from transmitters at the limit of their range. Some are heard and decoded, some are not.
LORA has the ability to change mode or spread factor (SF) and send data at a lower rate to improve range but I don’t know if this, known as adaptive data rate, happens with these trackers and gates as it needs two way transmission I think. They may just be set to SF12 which has the longest range.
