For these to be a usable tracker we're going to need ground stations. In the Kansas City metro, there's not many APRS digipeaters on 70cm, and the few there are use 1200 baud AFSK, not 9600 baud FSK.
==ST7 Programming==
The ST7 can be programmed using the RLINK-STD programmer. This programmer is available from Digi-Key https://www.digikey.com/en/products/detail/iotize/RLINK-STD/9923059
===FlashBash Programmer===
The FlashBash ST7 programmer claims to be able to program the ST7 on the LMS-6. This has not been evaluated yet. http://www.spen-soft.co.uk/

=====Circuit Power Options=====
The LMS-6 Inteface board offers four power options to power LMS-6. Components for any of the power options can be omitted if they will be unused to reduce the build the build cost.
======Battery Power======
The LMS-6 can be powered using three CR123 lithium batteries connected to the LMS-6 onboard battery holders. Batter power is enabled by jumpering Pin 1 and Pin to of J6 together.
======USB 5V Power======
The LMS-6 can be powered from the J4 Micro USB B connection. This is enabled by jumpering Pin 2 and Pin 3 of J2; Pin 2 and Pin 3 of J6.
USB power is indicated by D2 Green LED
=====USB to UART=====
The LMS-6 interface includes a FT-2232 USB to UART. UART1 is connected to GPS. The default baud rate for the GPS is 38400 bps. UART 2 TX is connected to U3 pin 19 on the LMS-6.
If the connections are wrong, they can swapped using JP1,JP2 and JP4, JP5.

==Reference==
Here are some reference materials. This is an initial population of material, and this section will need significant cleanup - putting links up for now.
