Hi, anyone try to use ATGM336H GPS module which is cheaper than ublox? I'm curious how to do the poweron? and what code need to change to use it with ICT FW? I hope anyone tried to do that Jan

70-72 mA transmit and 27-30 mA standby

I am in the process of ordering parts and boards.? Was curious, how much current does this tracker use while transmitting?? and while not transmitting? Thanks... -- Chuck / KG5CA StratoCasters

list is full all time :) propose make own list :) W dniu 01-02-2021 o?16:09, Kev via groups.io pisze: -- SQ9GOL Peter Greetings from Poland website: www.sq9gol.xyz '73

Konstantin, there is a group called Picoballoon /g/picoballoon which is much more active than this HAB Balloon group. You may find an answer to your question there more quickly than

thanks for the info, I hope I can figure it out

Hello Konstantin, good morning to you! Welcome in this beautiful hobby. I don't know exactly what channels are already occupied by others. I can tell you I use channel Q6 (telemetry message callsign

Hi, I sugest you use the wspr to hab script avalible from the original author https://github.com/sm3ulc/hab-wspr or the fork from https://github.com/reganhimself/hab-wspr let this run for at least 24h

Hi everyone. I have assembled several ICT trackers with standard firmware (using timing3). Did some tests using a 50 ohm resistor instead of an antenna - works great. Tell me how to find out which

You are welcome, Mr Chuck. I suggested the 0.6 thickness because it is a fair compromise between a thickness that gives lightness to the PCB but at the same time the necessary structural strength to

Roberto, Thanks for the referral.? Much appreciated. -- Chuck / KG5CA StratoCasters

Thanks...will check it out. -- Chuck / KG5CA StratoCasters

Hello gentleman Chuck. I use 0.6mm thickness and very cheap and high quality manufacturer jlcpcb.com. I wish you all the best. Roberto IZ7VHF Il giorno sab 23 gen 2021 alle ore 20:45 Chuck KG5CA

Question for those of you building ultra-small trackers for pico balloons: What thickness of FR4 boards are you using, and where do you get them manufactured? Many shops will build 0.0625" thick, but

Hi, nothing new out there really, ther was an improvement of the fw made a couple of month ago, I posted an updated fw here in November: /g/HABalloon/message/123 /Mikael

Dave, Can you please point to the repository for the information (schematic, board layout, firmware) on the ICT tracker?? I found a previous post in which Eduard attached a zip file with also this

Hi, For telemetry view download and run SM0ULC python script, where you will see what channels in use at the moment as the program scrapes wspr database for "hab channels"

Hi, I didn't figure out why such wide signal but on 10.1mhz is decode 400km away that is good. On 14MHz I'm still trying. How do you know for which transmitter is the telemetry, only with

Hi, no I have not seen that on my builds and I have been running them for countless amount of hours. Im guessing you will insert the switch at some point, if you try to run the board without it it
