Bob Crane Interviews Eric Schwartz of Elecraft About the New KX2 (with Si5351!)

Our ace correspondent Bob Crane W8SX caught up with Eric Schwartz WA6HHQ of Elecraft at the FDIM event n Dayton last month.    Here is Bob's interview with Eric:

Pete and I were very pleased to see that Elecraft made use of our beloved Si5351 chip in their amazing new KX2 rig.   Check it out:

Here's the KX2:

Three cheers for Elecraft!  Three cheers for Bob Crane! 

Excitatation! The Inspiring Knack Story of N3IC

Steve Silverman sent me this link.  This web site has been getting a lot of attention from the solder melting community.  And justifiably so.    Behold (above) the first transmitter built by Robert Glaser,  now N3IC, circa May 1969. The chassis and front panel were made from flimsy printing press sheet metal.  Note the key (as in lock and key) switch that the OM put on the front panel -- he took his responsibilities under FCC regs quite seriously.   My favorite part of this rig's story is that when he got it done, he didn't have the two 6146s for the final.  So he just took a capacitor and used it to connect the driver tube to the output network. Brilliant!  With that arrangement he made his first contact.  No wonder he labeled it "Excitatation!"  It was clearly more exciting than your standard excitation.  

Those TV power transformers look very familiar.  I was using similar devices to build a power supply for an HW-32A a few years after Dr. Glaser built this rig.  It's a wonder we survived.

FB.   Check out his site.  It is a wonderful catalog of all the stuff this very prolific builder has made over the years:

ANOTHER SSB Transceiver made in India

Spectacular Solar Weather

This amazing picture was taken last night at the Bharati Indian Base Station in the Larsemann Hills of Antarctica. The researchers there report that the aurora was so bright that it cast shadows.

Yesterday I was having a nice 40 meter SSB contact with N3TDE.  Rich is 179 miles away, in Pennsylvania.  At 1650 UTC, his signal very suddenly dropped into the noise. 

The purple lines along the bottom of the chart below probably explains both the aurora and the abrupt end of my 40 meter contact.

Re-purposed Computer Power Supply Box Provides a Home for a BITX Transceiver

Jaydip VU3JOJ came up with a really inventive way to box up his new BITX transceiver.  Nicely done. I especially like the way he put the speaker  in the space intended for the fan. Very nice.

This appears to be one of the new BITX 40 meter "modules" described in yesterday's blog post.  FB!  How fortunate the new board fits in the power supply boxes.  That's very lucky.

You know, I had an old computer power supply in my hand  just yesterday.  I almost threw it out.  Obviously that would have been a mistake.

Today was a BITX day.  Using my BITX DIGI-TIA on 40 I had a long QSO with Rich N3TDE.  Rich has a BIT20 built from a Hendricks kit acquired at Dayton.  He takes it with him on the Appalachian Trail.
