I'm not too familiar with a Built-in Scrambler & ANI code. Can you tell me exactly how this works and can I turn it off? Or could I transmit/recieve with a radio without this feature.
Specifically, I'm looking at the PX-777 Plus
Thanks again
while i don't know these radios, i have never seen a vhf/uhf radio where u could not turn the scrambler and ani functions off. actually i have never seen a uhf/vhf radio come with these functions active from the factory. you must activate both features with programming software.
the 'built in' scramblers are usually of the very cheap inversion type. the microphone audio and a tone (the inversion tone) from a 'tone generator' inside the radio is inserted into a audio mixer. this 'mixed' audio then modulates the rf output. on the receiving end, everything works in reverse.
the ani (automatic number identification) is basically a small burst of tones at the beginning or ending of a transmission that relates to an assigned identification # for each radio. these radios probably use the generic dtmf or 5-tone ani formats.
Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
