Re: Carriers everywhere

Wow, Joe, When I tested I was only looking at 1 to 30Mhz for the spurs
and harmonics.
Will have to look at maybe a 1 to 500Mhz span.

Thanks for sharing

I¡¯ve been noticing that as I tune around on the ubitx I hear my uhf/vhf Radio¡¯s breaking squelch. Today I took a look and see the carrier.

At 3.555.4 I see a carrier at 145.640.

Without the antenna connected to the uBitx and checking from antennas on the roof. My SDR shows a signal of 4 S units. And the uhf/vhf radio was practically full bars. The signal is full quieting.

If I unplug the raduino from the radio and power from usb the carrier drops significantly, but still there. That¡¯s some strong clock signal there. Anyway to filter it from above 30mhz?
