Re: TinyTrak4, bank switching

We need more information on your setup? ?? Are you switching banks at JP1 on the TT4 board, or using a switch on J1 pin 4?
?? If J1 pin 4, where are you getting Ground?
GKRELAY is only for KISS mode GRELAYRATE > 0 will cause GPS packets in the stream for TEXT mode
Although this wouldn't explain GPS sentences on BANK 1 in KISS mode, if you are TEXT mode on BANK 0 then the value of GKRELAY isn't important.
Are you changing modes with different banks?
Can you double check the voltage on the uP side of R8 for each state? Match these with the data flow.

That's how the manual states it should work.? For some reason my TT4 behaves just the opposite - open is bank 1, closed is bank 0.
Bank 0 is set with GKRELAY 1, Bank 1 GKRELAY 0.? GPS sentences show when I close/ground JP1
Idea is that I want Bank 0 for APRS and Bank 1 as Kiss TNC for Winlink & Packet
