It will be appreciated if you can help us improve the documents by correcting the errors, adding more demo codes or tutorials. Turn the potentiometer clockwise “right” carefully, until a pulse waveform is seen. Note that the adjustment of the comparator threshold described above is carried out at 10, in the 30m band.

This is more expensive but the modules are evidently of a higher quality.

This is how the ‘scope trace looks when the potentiometer is turned all the way anti-clockwise to its limiting position. Jodule that it is Ok to ignore ringing on the edges, this is not related to the potentiometer setting.

Additional Info SKU Turn the xd9850 clockwise “right” carefully, just a little at a time! You must have JavaScript enabled in your browser to utilize the functionality of this website. The adjustment is almost correct here, but still slightly too clockwise. Contact Follow us on Twitter. This is fine, not a problem.

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. The second dit speed ensures that nothing could possibly change state that could interfere with any measurement. Connect your favorite gear. Write Your Own Review Only registered users can write reviews. The duty can be adjust by a adjustable resistor – which change the adjust voltage level of the comparer.

The important pins are broken out to 0. Some failed to produce any output at all.

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

First name is required! 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.

For more information regarding pin functionality please consult the datasheet linked to above. Turn the potentiometer anti-clockwise “left” carefully, just a little at a time! The result should be a sharp, straight line without morule instabilities or wiggles.

Note that for these tests, the Zd9850 PA is actually disconnected. Call us toll free: All the way clockwise: The audio output of the receiver is fed into a laptop PC via a Logitech USB headset whose headset has been cut off and replaced by sockets, so that the USB audio ADC can be used to feed good quality audio into the laptop.
