P25 audio distortion

[EAFrizzle]

Heard a strange audio problem on my local P25 simulcast system. On both SDS 100 & 200, one radio had a problem that the other users were commenting about. It wasn't simulcast distortion or a blurb of encryption. The lady's voice could be heard speaking, and a second voice echoing those words, except sounding like the Borg collective.

Is this something that happens occasionally, or is it just a toasted radio?

On a P25 system, it takes time to encode and decode a digital signal which results in a delay. If someone else with a radio is standing close to the person transmitting, you will hear an echo from the other radio. This is different from analog radios where the transmit/receive delay is negligible. An analog radio nearby will result in feedback.

one of the many reasons I could never be a dispatcher is because with my sensor of humor when I would hear one of the echoes I would key up with"go...go...go.. ahead...ahead...ahead"

While I am currently working on my INTD PTB…I could never do it full time. Too many differences in audio levels of those that talk into their radios versus those who talk within the vicinity of their radios.
