Looking for 1kpcs of MK484

Googled "system on chip radio"

Ladda at kitsrus.com might have some.

Best regards, Spehro Pefhany

You'd have to ask the manufacturer but I doubt they still make them:

I don't know this store but it's in stock, you'd have to ask how many they have:

Slim pickens. There are much larger chips like the TEA5711 one but even that's hard to find. The Sony CXA1600 is probably gone as well. I believe there just isn't any serious market for this stuff.

Thanks I have been thinking about the SiLabs parts. These require a micro to drive to drive them.

The SiLab's parts are about 2.96 USD + Micro where as the MK484is less than a dollar (I think)

Where as the MK484 requires only s tuned circuit to select the frequency.

I'm trying work out a way to use a MK484 on a set frequency with minimal drift across operating temp.

Great! I used to work for DSE (dick smith electronics) and still have some contacts in the company. I'll give them ago.

Long term though I want 1kpcs

A ferrite rod antenna typically has a low enough Q factor to not need retuning with temperature changes of the ordinary kind.

The chip only works across the AM band, plus a bit each end, you know.

Sounds to me like you are doing something quite daft with it.

Thanks for your comments on the drift of the ant coil that is incrraging.

I've been checking out data on 0805 npo 1% cap's they seem quite stable also.

One mans daft idea is another mans brilliant idea.

Just design a simple TRF receiver with a couple of transistors.
