Fun kit to build and very professional looking when completed.
However, having just completed the construction, I was surprised to discover several issues.
First, and most importantly, the receiver opens with the no 75 message and defaults to the frequency. Unfortunately, it only tunes 3.839 to 3.840 (the default frequency) and no other frequencies. I cannot select any other frequency.
Second, depressing the tune button does not dim the display (not a big concern) but it does allow me to bring up the 1.901 or 1.902 setting.
Third, the LED does dim with a strong signal present as from a signal generator.
Fourth, I do have audio from the speaker and headphone jack.
My question is what may be the cause of limited frequency selection?
In advance, thanks!
