Just looking for help or thoughts what to look for on this transmitter circuit inside my RC boat. To explain, I have inside my boat a modified fish finder system in that I have the transducer fitted in the hull connected to a transmitter which than sends the data via 868mhz to handheld unit I have on shore. This display gives me the depth, temp, etc. I guess the same principle as drones that send video feeds but instead this is the classic display you would see on fish finder hard wired but it’s wireless
The signal keeps dropping out at around 80 yards and I have no clue what has been causing it. The normal max range is 500+. I have had the multi meter connected and it’s consistently 12.06 volts being sent into this circuit via the dc -dc power regulator (This is the requirement for the transducer to run. Seriously doing my head in now as I have virtually covered everything, and it still doesn’t want work. I have checked everything including antenna cable, changing antennas as well.
I have gathered that the fault does not exist in the hand-held unit I have on shore as it works perfectly with another boat that a friend has. It appears the transmitter in my boat is the issue
Any thoughts what I should looking for on this circuit would be greatly appreciated! Also, my wife is hoping I fix this because she is sick of hearing about this!
