The ultra-low cost CW HF transceivers you see on eBay such as the Pixie and Frog Sounds kits are great fun and certainly value for money. You couldn’t buy the components for the price.
Local ham Stephen, VK2BLQ, and I have played with these in the past (we had a Feld Hellschreiber contact once), but he’s gone on to enhance a Frog Sounds transceiver by adding a CDV VFO from OzQRP, a Rockmite iambic keyer and a variable CW filter and speaker amplifier.
Here’s how it looks.
As you see it's even "Juliano" blue.
