(The level transmitted is two times lower (-6 dB) than the peak level of 4 simultaneous tones. This may help transmitters with deviation limiters to make the phone ring.) Add command line option "-P 50" to send each tone for 50 milliseconds. Try something between 20-100 milliseconds, if the phone still doesn't ring. Be sure to check: Does your transmitter has enough frequency deviation (15 KHz is suggested)? Do you really send the correct number of your phone, check the frequencies of your phone and use "-D 0" option to see what 4 frequencies the base station actually transmits. diff --git a/docs/index.html b/docs/index.html index 33178ed..ae452a9 100644 --- a/docs/index.html +++ b/docs/index.html @@ -24,7 +24,15 @@ AMPS (Advanced Mobile Phone Service) ; my radio setup
