Some kit builders have noted poor output on 10m, which has been resolved by very very slight adjustment of the comparator potentiometer.

Note that for these tests, the U3 PA is actually disconnected. To test the frequency stability, a simple 30m band direct conversion receiver is used, powered from a well-regulated linear power supply. Contact Follow us on Twitter.

The Answer is 42!!: AD Signal Generator

In this condition the Ultimate3 will produce power output, but much less than it optimally should. Since it may not be easy for many kit constructors to carry out this adjustment, and there are already enough variables, it seems only polite for QRP Labs to supply the module ready-adjusted.

Upon switch on of a new AD module of course, there is some warm-up drift of the MHz crystal reference oscillator, which shows as drift of the ARGO line. Only registered users can write reviews.

Effectively therefore, the kit is simply transmitting a continuous carrier at 10, The adjustment is quite sensitive, the tiniest movement of the potentiometer affects the output waveform, and for the majority of the potentiometer’s travel, there is no waveform output at all.
