Hi folks
All the EVs I’ve converted over the years until 2011 , Electro Metro, Cushman,
Cheese Wedge, Geo Tracker, Porsche 914, Karmann Ghia, I was able to pick up all
radio stations including AM but mostly listen to NPR on low band FM. I used to

Interestingly enough, the noise is coming in on the FM band.
I like Jay’s idea of a separate 12v battery and a 2p2t switch - just need
to find a place for the other battery.
Thanks for all your suggestions,

Well the only solution then is to encase the AM radio in Cavorite. Or listen to

There is zero hope for an AM radio to function correctly in a home built
EV.
You are inside a metal box next to a 100 kW unshielded broadband AM
radio transmitter.
Many of the early OEM EV's simply didn't have an AM radio at all, for
just this issue.

Separate small (motorcycle sized) 12v battery behind a 2p2t switch to
separate both positive & negative lines powering the radio only. Turn
switch on to charge battery from DC2DC, turn off when you want to listen
to the radio. [If the interference really is only coming along the
power
Try connecting the radio to a separate battery isolated from the vehicle

Forget about it. THink of the converter as a 10 kW Pulse RDIO TRANSMITTER.
Unless car is designed from ground up to eliminate EMI, it just is impossible.

Oh by the way,
I too have a lightly used Geo Metro Tracker 1996 in Glen Burnie Md
that is going on the market soon. 4 wheel drive, etc.
Still gas though...

AM radio will pick up EMI via the antenna. A portable AM radio won't
work in a homebuilt EV. No hope.
A small portable AM radio is a very useful sensor for crude EMI leak
detection. Tune to a vacant portion on the dial and move the radio
around the device to find were EMI is leaking out.
Could you power the radio from its own battery? Charge it separately with
its own charger.

Radio, particularly AM, is a lost cause on home conversions. The EMI and
RFI is just to difficult for the home converter to deal with. Takes
serious and time consuming work on shielding and filtering of the EV
components and wiring to get it down to a level where you can listen to
an ordinary
I forgot to add - I would like to avoid getting a new dc-dc converter if
possible.

Hello Everyone,
I have a Geo Metro that I converted electric and the radio has never been
able to pick up more than one station because of all the noise the dc-dc
converter outputs. I have been able to verify that the noise is being
picked up through the 12 volt input of the radio and not through
15 matches
