Pete and the QRPARCI HOF: We thank you for your support!

Note the strange seasonality of these kinds of events... Always in the Springtime...

April is the cruelest month. Especially the FIRST DAY!


Feel Tech Follow-up -- the DC blocking cap issue.
HBTV? Roku Challenge?
A tube of Desitin? Why?

SDR Misadventures. SDR on a tablet Just like WA7HRG

Pi Day More RaspPi Linux observations TOO HARD

The problem of Si5351 and updated libraries -- old sketches don't work!

My SDR question: If we go with direct sampling, no need for I and Q at front end No image problem, right? But why is there often a digital I and Q in the direct sampling receivers?


BITX MODULE

Getting RF in through the DDS jack.


Electric Radio: Reading from the history of SSB. And from the T.O.M. article

Joe Carr K4IPV : Homebrew Hero from Falls Church Va. Any more info on him?


Pete's newest DifX Pete's new digital scope.

Bill's NE602 RIG, Epiphyte History.

He put AADE crystal filter impedance match circuits in backward That's why he needed RF amp. Duh.

The perils of a crowded box

Building RF amp board (BITX Module design) for the NE602 rig.

NE602s do not put out a lot of power. uW

BITX Module Amp circuits very stable.

Chassis as the heat sink.

Mic amp? We don't need no stinkin' mic amp! But yes, we do. 741 on the way.




Parts on e-bay very expensive! Back to the hamfests. On to Manassas!



Congrats to Tony Fishpool G4WIF, who received the Don Cameron, G4STT, Award for an outstanding contribution to low power amateur radio at the RSGB AGM meeting in Cardiff.
