— The San Francisco case against me. One guy thinks we DESERVE prosecution! Get off of my lawn!
Like the library cop on Seinfeld: https://www.youtube.com/watch?v=D9tP9fI2zbE
But one fellow wrote letter to the mayor asking for leniency. Proposes “Bill Meara Day in SF.” FB! I fell victim myself this year: Mike WU2D got me with WA1HLR on SSB video. https://www.youtube.com/watch?v=NLvCNJ_OnEc
— Oh no! Did our “Mailbag” come from Radio Moscow? Moscow Mailbag? SWLing Post.
— New Book by guy who made Gilbert Cells clear: Communications Electronics: RF Design by Steven Long AC6T UCSB (Amazon!)
— Dean: Fighting a spur in the sBITX. Filters?
— Dean: Expolring Class A, Class AB and the RD06HHF1
— Dean and Bill: OIP3 measurement and setting the bias on an RD06HHF1
— Pete: Discovers for all of us “RF Man” He is the THE MAN!
— MXM news. New docs, and ads from WD5L. All on the blog. 7030 crystals. Why MXM? Chuck Adam’s mods, Joh DL6ID’s questions about VFO. Yes! VFO from RX. Was Bruce Williams an early Swan Designer?
— Weird paradox with 25 MHz filter: Low profile xtals have higher Q, but produce more rounded passbands. Why? I note that Minima’s 20 MHz filter also had curved passband.
— Allison’s wisdom on filters at higher frequencies. The importance of physical layout. Diodes in the dark! It is indeed more difficult up there. But don’t let the perfct be the enemy of the good!
Should Bill build a MC1496 DBM Gilbert Cell Balanced Modulator? Or are two diodes or an SBL-1 good enough?
— VWS goes Meshtatic. What the heck is Meshtatic?
— Did my receiver sound tinny due to rising frequency response of uBITX Rev 4 amp?
— The Woebot. AI therapy for us!
— Bill BLOWS UP a Tiny SA Ultra. Ooops. But quickly got a new one from R&L Electronics. Veru very useful. I knew 25 MHz IF rigs were inferior, but by how much? How much was the carrier suppressed? Which filters worked better? What was the opposite sideband rejection. TinySA permitted measurement and comparison.
— Is Bill the only one to ever build a 10-15 Dual Bander using a 25 MHz crystal filter. Why? Farhan’s Minima has a 20 MHz 6 pole QER crystal filter. And it too had a rounded passband. But it too WORKED.
— Bill quits 15 meter SSB (for the moment) and goes to the 1.22 nanometer band with a Wilson Clound Chamber.
SHAMELESS COMMERCE: Thanks to new Patreon sponsors. I am sending some additional video content to the sponsors.
