#370: FX-4CR Transceiver PCB replacement procedure

The FX-4CR is the updated version of the FX-4C by BG2FX that I previously reviewed in this video:
The "CR" version includes a wider waterfall spectrum, built-in Bluetooth, up to 20W output and more. See the product webpage for more info:
There was a small hardware improvement made on this rig after the initial production run. The designer graciously sent the owners of the early units an upgraded circuit board. This video shows how to replace it.

Interesting. First time I have seen inside one of these. It looks really well engineered

Quality work, Alan. I got the impression that the trx seems to be a quality product. Boards look nicely designed. Thanks for sharing

I learn so many things from you, u r an epitome of engineering.. Thank you

wow professional work. great job 73 from kb2uew

Great Video... That was a lot of work to film and cut. 👏

I would love to see a video on SDR. I find passive radar using 2 or more SDR dongles, very interesting.
You did a video on SDR 8 years ago.

awesome video with the steps. Thank you

Thanks for the video Alan, my FX-4CR has not shipped yet, I assume they will install the new board before it ships but it seems pretty easy to swap out.

Prosím, jaké polovodiře jsou použity na přepínání LPF? Vidím tam 6 pin SMD, ale popis nevidím.

Hi there. I am trying to find something like this that can go to 490 and 518khz in CW to use for Navtex. Is there something you can suggest? Thank you!

[ekendraedrisinghe]

I wonder if the waterfall can be used to change the frequency?

[wgxdz]

When did you buy yours? Any idea after what date of purchase, the radio will be shipped with a newer board?

[JeffCowan]

When did you get yours? I haven't received mine yet and was in the early group.

[FreejackVesa]

Could someone explain what the use of this device is? I realize it's a radio but what other details might be available? RF is not an area that I have a lot of experience with.

[petrokrp]

Do you have some reported problems like Issue 1: Audio artifacts while calling CQ
Issue 2: Loss of sidetone while transmitting …?

[jever]

In Praxis, what are the difference between this and the older PCB?

[Mr_Meowingtons]

tape the new ribbon cables into the inside of the case so you never lose them..
