I would first check the swr for the two radios. If the swr is high it could cause the transmitter to go spurious. I would also consider reject cavities to keep one transmitter out of the other one. Relocating the antennas is also an option or reducing tx power. Relocating one antenna over the other so it is in the shadow of the other and vertically separated as much as possible is helpful, but not necessarily a solution. Just a couple of thoughts for you.
Hi All, Im having an issue with my APRS Digi intefering with some other equipment. Im running my APRS Digi, iGate and weather node on a Pi 4 with a NW Digital Draws HAT interfaced with a Kenwood TM-D710A. Every time the Digi fires via RF it desenses the IC-9700 machine to a level its not usable for weak signal stuff. Currently im manually shutting DW down when im using 9700 then starting it up when finished. Id like to automate this process if possible. My immediate though it that i could use a GPIO input to trigger a script which shuts down DW then starts it with a different .conf file that doesnt run the RF digi and only iGates. Optimally Ill be able to provide that GPIO input directly from the 9700 when while powered on. Then when the 9700 is shutdown, the GPIO will go low and a script will then restart DW with the full function .conf.?
?
This sounds like an interesting project (I say project as my Linux skills are still in development :)?
?
My question is: Does anyone have any ideas how i may accomplish something similar a bit easier.?
?
Thanks,
