FB Stuart!  Great work.  Pete is sending you info on a Low Pass filter that will clean up that harmonic-rich signal.

Summary:

• Decide if its important to do
• Study the prior work of others

• Don't get discourage, ask questions, finish what you start

There is a lot of tribal knowledge and homebrew wisdom in this link.  I tried to find a picture of OM Dave, but he has kept a low profile on the www.  The best I could come up with is a symbol of the club that he has been associated with.  Thanks Dave!

Brazilian Minimalism: The Curruira Transmitter

Miguel PY2OHH is the Wizard of Sao Paulo. This morning I was looking at his wonderful web site and came across this little rig.  It seems a bit simpler than our beloved Michigan Mighty Mite.  And the folks down in Brazil had several of these on the air and made contacts with them.  FB.  Miguel hints they may turn this rig into a transceiver. 

Here is the Curruira:

The rig is named for this little bird: 

 

 

Gregory Charvat HAS THE KNACK

Gregory Charvat N8ZRY

Yesterday I was talking to Allen W5SQK on 17.  He mentioned that he been working in his shop. You don't hear that too often these days, so naturally I asked what he was working on.  Turns out that OM Allen is building a coffee can radar!   He is enrolled in the MIT Lincoln Lab's Open Courseware Project (which looks very cool).  We had a great QSO, sharing tales of woe about the release of magic smoke from (dis)integrated circuits.  These are the things that pull us together my friends!

 

On the MIT page the name of a faculty member caught my eye: Dr. Gregory Charvat N8ZRY. Greg's rigs have been discussed on this blog at least twice, but it wasn't until today that I became aware of his many other interesting technical activities.

Nightmare Turns Real: "Rig Here is a Raspberry Pi OM, and I'm listening to you with my Dongle..."

As with many other nightmarish things, this one was launched at the world on Halloween. It all seems a bit flaky, but we knew this was coming.  Don't complain to me about the lack of low-pass filters, SSB testing on 7.000 MHz,  or the rather nebulous identity of the creator.... I'm just the messenger here.  And remember that I am a HARDWARE Defined Radio,  Discrete Component,  "Menus are for Restaurants" and (now) "Pi's are for eating" kind of ham. 

Here it is:
