Audio Distortion

[PrepperAES]

Hello all, I own an XTS5000 and I’m casually getting some audio garbling if I move it around a lot (running etc), is this related to tuning or is reception a main issue since I am around 15 Kilometres away from the Repeater (P25 Conventional). Its not that big of a problem but any input would be helpful.

Hello all, I own an XTS5000 and I’m casually getting some audio garbling if I move it around a lot (running etc), is this related to tuning or is reception a main issue since I am around 15 Kilometres away from the Repeater (P25 Conventional).

A little known problem of P25 (It affects analog as well but you would not notice), is if there is metal nearby making contact with other metal objects of the radio itself. Hanging a ring of keys on the antenna will distort both reception and transmission. Likewise wearing a suit of armor or big gold chain would be a bad thing. Another problem could be flexing of the radio and/or antenna themselves if there are loose bits in the radio like battery plate or shields.

Yep, those interconnect pins will also corrode over time and cause static/popping on analog and digital garble on P25. Sometimes cleaning the contacts on the RF board and VOCON will clear it up, but it may come back. These are, after all, two decade old radios and bound to start exhibiting age related problems.

Yeah I have a relatively dirty radio with a keychain on it if that makes any sense, your both literally spot on, thanks so much, i usually don’t use my radio but I will also clean the contacts.

Hello Everyone, ive moved everything possibly metal or that could interfere with the rx away from the radio or gotten rid of it but i am still having the same issue, any input?

It could just be reception at 15 km (9 mi), especially if there's stuff in the way, like terrain or buildings. Do you have another radio to compare it against? What frequency band?

Yeah im guessing reception, I’m using it indoors most of the time and my radio is 19 years or so old.

When's the last time it had an alignment?

 

[AM909]

Age doesn't matter too much in the specs, FWIW. On UHF(R2), 5% BER spec for APX-NEXT is 0.178 µV while the XTS5000 is 0.200 µV, about 1 dB worse – generally insignificant compared to other variables, like the angle you hold the radio, the weather, what the signal is bouncing off of at any given moment, etc. Now if it hasn't seen a service bench in years, ...

My radio hasn’t had an alignment for im guessing around 3-5 years,it is a uhf 380-470MHz model.
