WebbThe unit lost lock at +6V supply, by which time the RF output power was effectively zero. The DC to RF efficiency of the FMX is not good, considering the Broadcast Warehouse 1W LCD PLL Transmitter puts out over 5 times the output power (800mW nominal at +13.8V supply) for twice the supply current. The small current drain of this unit makes battery … WebbTo tune in a strong AM station, first put the receiver in synchronous-AM mode with the PLL turned off. The beat between the AM carrier and the HFO will be audible in the speaker, and visible in the LEDs turning on and off alternately. Tune the HFO in 1 Hz steps until the beat is slowest, then turn on the loop.
