SolderSmoke Podcast #197: Farhan, Fame, 'Fest, Testgear, SSB History, Dishal Dystopia, QRP CW, MAILBAG

SolderSmoke Podcast #197 is available:

Up in NYC, met Dave W2DAB. got Steve Silverman's HP 8640B Sig Gen.

Farhan's visit to SolderSmoke HQ
Got me a TEK1401A Spectrum analyzer
Farhan at "Geekfest" @W7ZOI   http://w7zoi.net/Farhan-visit.html

BITX40 Modules.  5,000 already.   1,000 a month.
The BITX pronunciation problem. 

QRP Hall of Fame.  I suspected April 1 reprisal!    "I am unworthy" 
Dusting off my Tuna Tin 2, Herring Aid 5 and Farhan's key from India.

The Manassas Hamfest:  OLD crystal gear.   20's and 30's stuff. Leon Lambert RX and Philmore Fixed Crystal Detector. 
 Reminder of how YOUNG the radio art is.
RELATED:  Bell System 1953 Transistor Documentary.  11 year old Pete and his CK722.
Bought some good stuff from Charles AI4OT.

Armand WA1UQO gave me a big collection of Electric Radio.  So much history and HB wisdom in there. Frank Jones and Lafayette Radio.  Jim Lamb and 1930s SSB.  

Is the CK-722 the source of Pete Juliano's affinity for Juliano Blue?
Was Wes Hayward already using Juliano Blue?

"Your rig sounds real good for a homebrew rig!" 
"Well, your rig sounds pretty good for a Yaesu!"

ARRL Arduino Book   by Popiel.    Very nice.  Right level.  Lots of good info.


Pete's Dishal Dystopia --  Is the perfect TRULY the enemy of the good enough?

Bill's  NE602 RIG: 
Replaced OLED.  Blue one seems noisier.  Shielded it with  copper flashing.
Made me yearn for bigger boxes WITH A HOOD!


Special Thanks to our correspondent in the Dayton Xenia Metropolitan area -- Bob Crane W8SX.

Jack Welch, AI4SV 5R8SV -- Our Man in Antanarivo -- Sent me a GREAT BOOK "I, Libertine" by Frederick R. Ewing.   EXCELSIOR!

Bruce KC1FSZ https://www.qrz.com/db/kc1fsz  Building Scratchbuilt BITX.  On the way put the VFO where the BFO should go and had a DC RX.  FB

Greg, VK1VXG   Suggestion for WA8WDQ on Arduino serial plotter

Ben KC9DLM  Mercury PTO.  In a syringe!   No thanks! Maybe add some high voltage and selenium.  And a radium dial!  Yea!

KY3R's metalized cigar boxes!  FB On Blog.

Richard WB2PEF has revived his Doug DeMaw 8P6 rig.  FB.  But bothered by PTT thump.

Update on Dave AA7EE (from Mike KC6SAX)



  1. Thanks for the kind words. I heard Glen Popiel speak at the Hamvention. Really good information. I might have to get his book.
    The OLEDs are really noisy, but like you pointed out, Bill, the band noise on 40 tends to drowned it out. I wonder if it is imparted on transmit? More bench time required!!!


  2. Feathering is something that the audiofools can see on a signal after they have sucked all the oxygen out of the copper.

  3. Hi Pete and Bill. Don't dismiss the 'feathering'. It could be down to intermodulation in the PA after the filter (or in the SDR front-end!). Similarly, the ultimate crystal filter is no good if intermodulation in the PA or receive front-end limits performance.
