Project Minima has come to the end.
The
distance to IW2KGW is 1569 km, report 44, antenna 3 el Beam.
The
distance to SP6PYP is 789 km, report 57, antenna sky-loop 82m.
Modification
not menschen earlier.
CW
modulation take the signal from collector T17 and R43 connect 2,2uF and serial
180kohm to mic in.
This was
adjusted after R33 220ohm changed to trim pot 500 ohm, to adjust
modulation from mic.
100nF put
in LP-Filter close to T+ pin (input regulator).
100nF put
in LP-Filter close to +12V pin (input regulator).
I have no
run QSO on 80m, 40m and 20m. I rely like the little fantastic Rig. It has built
in CW memory for short CQ. Also QRSS Message not practiced yet. I think I have
not found all feature yet.
It is close
to unrealistic what is possible with this small rig. Width 18cm Depth
20cm Height 8cm Weight 1150 gram.
No I
stopped soldering, no more measurement and go for practice with this QRP
MINIMA.
If its
unclear wat I have done you are welcome to email (Calsign@gmail.com) if you won’t more detail. Or put
in a comment down hear.
SW is very
close to Eldon Brown work really nice, Eldons Code TANKS a Lot.
I add a Rx-preamp +14dB its perfect when its weak signals.
Hope to her
you on the band.

Leif, gongrats on the nice blog! Please, tell me which schematic you are referring to? For example which are T17 and R43?
