"Yes that is correct.  You need an level shifter / inverter to get TTL serial.  Some people have used a RS232 to USB converter with success.  The three pieces of data you mentioned are native to the taranis but beyond that it is just a transparent…"

"you could try putting some Ferrite beads on the communication leads as close as possible to the ends.  It could be that RF that strong is coupling into the com lines and causing the problem.  If you can shield the boards it might also help if this…"

"There is a really awesome highly directive yagi antenna for 900MHZ you can build at home with simple tools for about 5 bucks included in this group of antenna designs.  You can mark the elements and wood boom so you can take them in and out for…"

"Something important to keep in mind.  Typically when people who aren't RF design people (and even some that are) think about improving a radio link, the first thing they consider is upping the power.  Boosting the power requires more battery, better…"

"Here is a handy tool for figuring out your link budget:

Also you can easily make your own antennas like the V antenna in Richard Kennedy's second post.
It isn't hard to make really good high…"

"Depends on your application.  If it is simplex then one should do but for duplex you have the same link budget from both ends so you better have two!"

"Has anybody tried the MP SiK V 2.5 firmware?  I have V2.4 running now  but am curious to try the latest version.  I don't have the tools to build it.  Can anybody here upload an .ihx file?
I would really appreciate it.
