AMB20 poor loop range?

[andrewc]

Hi all

Had problems with our AMB20 system last night; has run reliably for months, but last night the loop had little on no range, as in transponder had to literally be run across the carpet for it to receive, and still this was unreliable.

Tried changing the coax and the loop, tried multiple transponders, checked transponder voltages, now wondering if it's the box?

Anyone with any experience of this specific issue? Open to the fact it might still be loop/coax but ran out of time last night to fix at club.

Any advice appreciated on things to test, if not, any advice on the right people to get this fixed for a reasonable price appreciated.

Thanks, Andrew on behalf on 1066 Racing
