AC/DC pwr. sup. for KX1?

Good Day All,

New to KX1. I'd greatly appreciate any recommendations for a wall wart
for this rig. Tnx.

John,

Be careful of wall warts. If you know it is a regulated one, then all
is well, but most are unregulated and the voltage will soar with no load
and drop to its rated voltage at full rated load. I have measured many
"12 volt" wall warts at 17 volts. The KX1 is rated for 15 volts maximum.

73,

Thanks so much for these replies and addressing my question in such a
helpful way. Most things electric are still a deep mystery to me, so
I'm moving slowly and cautiously.

Hi John,
go and visit the review of MFJ-4103 at eham.net and you will discover
that such a power supply generates a lot of noise into RX...
Hope this help.

regulator).
That did the trick for my kx1, but choice a power supply that can
deliver around 17 V so to have the right amount of voltage dissipated
into 7812.

I have not experienced this with my MFJ-4103, but I suspect that there is a fair amount of unit-to-unit variation in many MFJ products.

My MFJ-4103 has also been noise free. Use it with K1, KX1 and Flex-1500
