New BitX40 kit

Just to add on to the announcements for new transceivers, the BitX has been resurrected as a low cost 40m kit with pre-soldered SMT parts and an arduino controlled DDS! The kit does not come with things like a speaker, power supply, or enclosure, but there’s a lot of potential for experimentation/hacking. Probably my favorite feature is the separate parallel power jack for the PA stage that will boost output from 5-7W to more than 20W. I’m already planning on replacing the LCD screen with an OLED for cold temperature operation and adding a digital filter module from SOTABEAMS.

I missed my chance to pick up a KN-Q7A when the unit reached EOL last summer, so I went ahead and ordered myself a late Christmas present (at $59 USD I couldn’t resist.) Shipping is free internationally from India but takes three weeks.

Video review from VK3YE (non-DDS version): Review: Low cost Bitx40 7 MHz SSB transceiver module - YouTube


ordered one a couple of weeks ago and I added the DDS later too! Cant wait to see it!

I ordered one 10 days ago (not that I need another radio) but it does look like an interesting project and one that I think deserves support.

VK3YE has been busy creating and posting interesting videos related to the BitX40.
