Is this the cheapest multiband SSB transceiver?

Probably the cheapest multiband HF SSB amateur transceiver you can get is the uBitx, designed by Ashhar Farhan VU2ESE. It's a kit but with the main board assembled. You just need to find a box and solder up the connections to the external power, speaker, antenna, microphone, and key sockets. And make a few other adjustments (which can be a bit tricky). 

It's not perfect. Operating isn't as smooth as say a Yaesu FT817 or 818. But the kit has been refined over time. This portable session is a taste of what it's like on-air. 

A lot has been written online about the uBitx. I've done a few videos myself. I've put together a few of the best resources about it on my website here. 

PS: The uBitx is a QRP-ish transceiver. Want to get the most from it? Minimum QRP is what you need.
