Belle journ???eHi all !
I just finished assembling my U-QRSS-Kit for 30m.
It seems to work fine at once except the frequency. I couldn't get it higher than 10 139,840 Mhz with adj C8 at minimum.
I replaced C5 (22pF) by 15pF. The freq has up a bit to 10 140,120 Mhz which is still a bit low (for example WSPR is around 10 140,200 +/- 100).
I replaced C4 (22pF) by 15pF. This didn't change anything for the freq ! By the way I don't understand why ?
However 10 140,120 MHz beeing still too low I wonder what is to be done now :
Must I reduce C5 to a lower value (let's say 10pF) ?
Must I reduce C3 ?
I will greatly appreciate your experience and your opinion.
73's to all of you.
