A while ago, the #SolderSmoke podcast issued a challenge to build a direct conversion receiver.
The ham shack resource manager (KA1PQK) at #MakeItLabs organized a group project. Together, we each built our own copy of each module.
I decided to go further than mounting it on a simple board ...

#Soldersmoke Direct Conversion Receiver challenge. Last night we assembled the boards and tested them out. Tuning is fussy, but it worked! Not for some woodworking and other "packaging" details!

Last night's build in the #SolderSmoke Challenge was the last module - the audio amplifier. Now to connect them all together in the cigar box I found to house the completed project.

: "only the band shall pass"

Looks good but could be better. Going to replace the caps with silver mica once to see if it improves.

Part 3 of the #soldersmoke #directconversion #receiver #challenge
: "mix it all up"

Looking at the output of the mixer. With my #rigol signal generator and with the PTO signal.

Looking at the output of the PTO.

The PTO is build, working and has a nice tuning range.

40 meter (7 MHz) band pass filter

Last night's build was the band filter for the #SolderSmoke Direct Conversion Receiver Challenge. Three out of four boards complete!

This week's part of the #SolderSmoke Direct Conversion Receiver project was the mixer board. I don't know how my soldering skills could have gotten even worse! :-) As bad as it looks, it is "mixin."

Several of us at #MakeItLabs have begun constructing the #SolderSmoke challenge direct conversion receiver. Last night we built the oscillator. Please forgive my poor soldering skills. :-)
