Adjustment is done by setting the tuner to a frequency of a radio station and then tuning the coil until you receive it. I came up with an Arduino library for MxLT. Tuner PCB in a new metal case Everything was connected with tiny pieces of thin wire to a small piece of circuit board that held also the pins on the metal case. You will hear neighboring stations while adjusting local oscillator coil, because signals from a piece of First conversion takes place inside the tuner and the second one at the mixer of TA I will show you how I took it out from a receiver so I can use it in my projects.

The mixing result must be an IF at a common frequency, such as the Also Fi2 must be replaced. I assumed those are I2C bus lines. To see if I got the pinout right and test the reception I had to build a demodulator.

IF inversion does not affect the signal unless your detector is not centered on the right IF frequency. But, a closer look at the tuner which mxo5007t basically an area of the PCB enclosed in metallic box revealed only a few tracks coming out of the tuner area. Tuner PCB in a new metal case Everything was connected with tiny pieces of thin wire to a small piece of circuit board that held also the pins on the metal case. Whether or not you mxl50077t upon this IC in a receiver, it is good to know that sometimes you can work things out even without a datasheet.

Two other tracks are pulled up with 4. I went for the first method and built a double conversion receiver. Probably this is the IF output. Simpler design, but impossible to find filters. It has a programmable IF output and it can receive anything from 44 to MHz. After this frequency conversion, the resulting intermediate frequency signal is passed to a demodulator. First conversion takes place inside the tuner and the second one at the mixer of TA In the end, my tuner had fewer pins than the original one in the liux.

I re-used a metal box from a broken TV tuner. Take the IF from tuner and demodulate it at its frequency. The practical disadvantage of this double conversion is that you have to build and adjust the local oscillator LC pair.
Practical build of TA receiver on xml5007t MHz will be in the updated version of this post. Another two tracks come out from MxLT and are capacitor coupled.
These seem to be software limits, because the product brief sheet claims this IC can receive from 44 to MHz. Do not short them. Remember not to connect it to mxl5070t Arduino without level shifter.
I have no idea if this is an I-Q output or a simple differential output. Subscribe Don’t forget to check your email and confirm subscription. If you do this, remember always to tune set tuner frequency This should be mxl5007tt inside a can you know those RF can coils inside every radio.

Then I cut really the PCB and placed the tuner inside a metal box with easy to make connections. Take the IF from tuner, consider it as any RF signal and perform an extra conversion. Therefore local oscillator L. msl5007t
Frequency conversions are performed by mixing two signals the incoming RF with a local oscillator. The tuner is a an I2C slave device.
This IC can set IF center at 9. Do not connect the other to the ground.
