Re: On the Air! Finally!

Hi Dave:

Attached is an article I did for QRP Quarterly on using the mic parts that come with the BITX40 to make a mic. My cost was under $1.

I like your mic. ?How did you mount it in the pvc tube and did you add any packaging or padding material inside or any spit screen in front of mic cartridge? I was thinking of using a smaller diameter pvc tube but your larger size looks good and more functional to hold in your hand.

Good afternoon all.

I've finally got a Bitx40 on the air! Another local ham had acquired a Raduino version and decided he had too many projects to get it going so he sold it to me for just under cost. I swapped it out with the original version Bitx40 in the case that I'd already made and hooked it up as directed. It appears to be working exactly as designed. Phew! It's been a long time getting something on the air! Attached are a couple of photos of the completed unit. The only thing I'm not keen on is the travel of the pot before it switches to 100 kHz steps. Has anyone had any success with mods that folks have done to give more travel? I tried a 1meg pot but it didn't seem to make much difference. Aside from that, I'm thrilled to have it on the air.

I'll keep working on the original non-radiuno version, but at least it's not keeping me from getting contacts. I made a couple yesterday immediately after finishing the build.?

All the best!
