Softrock Lite II build day 1

Finally made some time to start building the Softrock Lite II SDR
receiver. The original plan was to build it as a pan adapter for my
TS-940S which has an IF out port. Since I no longer have this rig,
and my K3S has a different first IF, I decided to build it for 30m as
a WSPR receiver.

First test of the oscillator stage

Checking on the frequency counter confirms everything is working as
it is supposed to be.

Next up was the divider stage. All went fine, except with some need to
tidy up my soldering of SMD parts. First time I used a hot air rework
station for SMD parts. Not as easy as I thought, but turned out OK.

Again tested all the steps and made sure the voltage readings for example
were correct. It is really important to do this for each stage to make sure no
errors sneak in and then are harder to find later.

The divider provided the expected signal at the test points with the expected
frequency. So on to the next stages ….
