Unless your Becker is about 25+ years old, there is something wrong with
it. For decades, Beckers have worked to 10 volts.

From the installation manual:

'Supply voltage range 12.4 V to 15.1 V '

It will receive below 12V but will not transmit properly.

So it IS a 20+ year old design.

You will need to upgrades it to a 8.33KHz model before 2018 anyway.

Pity you missed Becker's trade-in offer.

Give them a call anyway, they may be friendly and make you at least some
offer.

Good luck!

Nonsense. I'll get another 2 years at least out of it. Then new 8.33 radios
will be under $1000

Some already are. I see that the Dittel KRT2 is already cheaper than when
I bought mine two years back.
