Change of transmission frequencies:
I have a radio scanner that transmits at 430 MHz but the transmission is very bad.
The first time I used it the system was working well: could it be that the transmission power has decreased?
I have also noticed that my scanner does not receive the UHF signal in the room where I have put the decoder for SAT TV.
Do you think that a technician could change the transmission frequency?
It is possible to change the transmission frequency by carrying out some changes in the electronics.
But bear in mind that the margin you will have within those frequencies is probably very small (2-3 MHz).
Here at the Televes factory, we do not carry out these type of adjustments.
You need to go to a TV specialist or somewhere that fixes radios and TV sets.
