Post date: Feb 2, 2019 4:08:48 AM

Charles NK8O shares with us a kit that is available via eBay:

From the seller:

Nothing new about this technology, it consists of two 600 ohm line transformers for audio input and output from your pc to your transceiver, and an opto-coupled push to talk circuit that works off of an RS-232 port on your computer.

Shipping is a tad expensive to Australia, $35.05

Same board with some more detail is here:
