Met Josh KE8CPD on 40.  BITX 40!
Socketry:  How to keep BNC jacks from spinning loose?
Do you heat shrink?
Feel Tech Sig Gen might not have blocking cap at the output.
Speaking of which, when I spoke of the Ne602, I mostly meant blocking caps, not bypass caps.

Bad weather.  Tailgaters wimped out!
Combined forces with Armand WA1UQO.
Met up with Charles AI4OT.
Acquisitions:  1/4 phono jacks, carbon mic, vero board, disc caps, weather radio,
LARGE collection of Electric Radios from Armand.  Wow.

Bench Report:  Pete working on Direct Conversion Receivers.  
Bill on his 2B and on 20DSB rig, and an M0XPD/Kanga DDS kit, and a 140 watt amp. 

Start simple:  Build an oscillator. Make it oscillate!
Gather tools, simple test gear, and books. 
Try to understand what you build. 
Build a direct conversion receiver.  
Don't fear the toroids! 
Be patient.  This is not Plug and Play. 
Build a DSB transceiver. 
Little tips: 
Protect variable caps. 
Use heat sinks. 
Use reverse polarity protection. 
Don't breathe the solder smoke! Ventilate your bench.
