Do not short them.
Tuner PCB in a new metal case Everything was connected with tiny pieces of thin wire to a small piece of circuit mxl5007 that held also the pins on the metal case. You know you got the right L. I re-used a metal box from a broken TV tuner.
I went for the first method and built a double conversion receiver. I have no idea if this is an I-Q output or a simple differential output. Here you can use an LC pair tuned to If you do this, remember always to tune set tuner frequency Whether or not you stumbled upon this IC in a receiver, it is good to know that sometimes you can work things out even without a datasheet. The mixing result must be an IF at a common frequency, such as the You will hear neighboring stations while adjusting local oscillator coil, because signals from a piece of Do not connect the other to the ground.

Take the IF from tuner, consider it as any Mxl5007 signal and perform an extra conversion. There are no datasheets to describe I2C interface, but the existing Linux drivers for hardware using this tuner provide enough information.
Knowing this there are three approaches: Practical build of TA receiver on 36 MHz will be in the updated version of this post. Fi1 will chop all signals except those around Post a Comment Please read the comments policy before publishing your comment. Subscribe Don’t forget to check your email and confirm subscription.
CONFIG_MEDIA_TUNER_MXL5007T: MaxLinear MxL5007T silicon tuner
There is no datasheet for it, but there are Linux drivers. I came up with an Arduino library for MxLT.
Testing continuity revealed it comes from a 3. These seem to be software limits, because the linix brief sheet claims this IC can receive from 44 to MHz.

The tuner is a an I2C slave device. It has a programmable IF output and it can receive anything from 44 to MHz.
Then I cut really the PCB and placed the tuner inside a metal box with easy to make connections. Frequency conversions are performed by mixing mlx5007t signals the incoming RF with a local oscillator.
The power supply line was assumed to be the track that has a mxl50077t width than the others and has some capacitors connected to ground. The practical disadvantage of this double conversion is that you have to build and adjust the local oscillator LC pair. Oinux design, but impossible to find filters. The frequency step of the tuner is This should be built inside a can you know those RF can coils inside every radio.
In the end, my tuner had fewer pins than the original one in the case. I will show you how I took it out from a receiver so I can use it in my projects. Although you pass frequency in Hz, it is rounded mxl507t multiples of Hz. Receiver specifications said it can receive to and to MHz.
