Hello John,
I must admit...that particular check, I skipped.? Bad practice, but I did.? Maybe someone one else on the group here can help you. ?
One warning...don't do what I did at the end of the build...I forgot to put the thermal pad in between the end plate and Q4...I'm sure I did no favors to the rig as the relays went crazy?and I got a bit of a zap from the power plug when I was plugging it in and pulling it out. ?

Good morning Kurt. My name is John and my call is K2JHU.? Congratulations on your 1st contact. I am in the process of building my D4D DBS. I have completed up to stage 4, the RX audio amplifier. However this test did not go as expected.?
When I touch pin 1 of the NE602 I don't hear anything. It might?be the impedance of the earphones I used are way off but not sure. Just wondering what you found at this stage.

Hi there...
Had my first FT8 contact tonight using my just completed D4D DSB.? This was also the first two way contact using the magloop prototype you see in the pic.? Thanks for the kit!
