Travelogue:<\/u> Cuba DSB and AM. Jose CO6EC and the Islander. We need more info, especially on the solid state Jaguey rig. <\/p>\n

Bill\u2019s bench: <\/u><\/p>\n

Will the High School DC receivers get finished? Future uncertain. But the project was technically interesting. Great working with Dean KK4DAS. Battling AM breakthrough from Radio Marti. We joked that Dean has been listening to Radio Marti so much that even though he doesn\u2019t speak Spanish, he has noticed an increased urge to liberate Havana. <\/p>\n

Audio amps: Harder than we thought. Lots of variation in Hfe of 2n3904s. Oscillations.
Not using feedback amps nor LM386s, nor push-pull. Simplicity is a design goal. <\/p>\n

Fixing the tuning (bandspread) problem on the VFO was fun. <\/p>\n

Antennas? A quarter wave with ground or counterpoise works well. We tried it. <\/b>(59) An Antenna for the TJ 40 Direct Conversion Receiver – YouTube<\/a>

Back to work on the uBITX. I chickened out on replacing the predriver with a BFR-106, but then \u2013 Just in time Todd K7TFC and his Mostly DIYRF came out with BFR106 boards! TRGHS. I will do the mods on two uBITX transceivers. I even bought a solder-sucking iron for the second job.<\/p>\n

Winterfest Hamfest. Big success. Thanks VWS. HERRING AID FIVE! Simpson 260! QF-1, Another Radio Shack DMM, Eamon Skelton\u2019s Homebrew Cookbook, Knobs, SWR meter.

Technical Note: Skype problems. Pete’s Skype kept dropping out. Bad in the last podcast (#244)<\/a>. Three minute gap. I was ready to scrap the whole podcast when Dean KK4DAS offered to help. And he is obviously well qualified: https:\/\/potomacofficersclub.com\/speakers\/dean-souleles\/<\/a> Dean went to work with AI. And he was able to fill the audio and the video gaps. Can you spot the three minutes of AI? Send me an e-mail with the time segment of the AI\/Deep Fake portion of SolderSmoke 244.<\/a> The first one with the correct answer will win a prize. <\/b><\/div>\n
