Henry:

What does your ferrite rod antenna look like?

Got a schematic? Circuit diagram? Picture?

Thanks in advance,
Regards,
JS

Hello John -

Send me a private message and I will mail you a picture. I don't have a schematic. It is all in memory. Basically a NE612 - MK484
combo with a IF LC-coil and a class-E transmitter amp. The baseband is a FSK modem built with a DSP.

You're interested in ferrite antennas?

- Henry
