Interference on portable tranceivers
« on: 13 August 2010, 16:41:27 »
Interference is caused on 2 different tranceivers, when engine is running and when not.
Particularly bad on 144.5 mhz which is unuseable
Anyone any advice please?

Not noticed it myself but will check. I take it it's from something in the car? Does the key have to be in the accessory position, or the run position?

I have no issues with noise on the 2 meter band in my Omega, but as it's a 95 I don't have that much electronics in it.

However, I do get a small range of noise when my stereo is on (Alpine head unit).

Does it happen all the time, or in certain situations? If it's there all the time I would think alarm system, info display (of any kind) or immobilizer transponder (although I think it's on 433'ish MHz).

Anyway, I reckon you're a ham then?  ;D

Hehe, yeah :)
Better set up some kind of OOF sked then? 80m is fine to UK usually.

Ahh, not a bad idea, actually. And a reminder to sort out my antenna system. ::)

Can't remember if it's the antenna or house wiring that's resonant on 80m at the moment. ;D

I'm an M1.

The rig hasn't been on for a while, so much else to do.

Think that makes me an older git then, G8P**, although not used it for a long while, guess that's what happens when you choose a career in Radio and Telecoms for the last 25 years.  ;)

G7xxx

144.5 iirc is prone to processor harmonic noise, particularly bad with old, old slow ones - so that may indeed suggest some damn chip that runs a display, gps, mobile phone unit, alarm unit, ecu etc -

To search you could try taking the antenna off the handy, seeing if it can still hear the noise and using it to try to pinpoint the source around the car?
