The FX-4CR is the updated version of the FX-4C by BG2FX that I previously reviewed in this video:
• #355: Radio Review: FX...
The "CR" version includes a wider waterfall spectrum, built-in Bluetooth, up to 20W output and more. See the product webpage for more info:
bg2fx.com/fx-4cr-transceiver
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

@tav9755 Год назад

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

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.

Thanks for the video!!

@caulktel Год назад

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.

@w2aew Год назад

Yes, all current/new shipments will have the new hardware. It was just the first 40 or 50 that were shipped a few months ago that were affected.

@Mr_Meowingtons Год назад

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

@vourkosdude Год назад

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!

@j204ever5 Год назад

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

@JeffCowan Год назад

Fewer spurious emissions

@petrok1rp254 Год назад

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

@w2aew Год назад

Yu sent me new firmware this evening that addresses the loss of sidetone.

@JeffCowan Год назад

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

@w2aew Год назад

Several weeks ago

@FreejackVesa Год назад

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.

@w2aew Год назад

This is a compact/portable transceiver (transmitter+receiver) designed for use with Amateur Radio, commonly known has Ham Radio. It supports the most common HF radio bands and modes used by licensed ham radio enthusiasts.

@FreejackVesa Год назад

@@w2aew neat. Thanks! Great channel by the way. I have learned a lot from you even though I don't really work in the RF realm

@w2aew Год назад

@@FreejackVesa Thank you - there's a lot more here than just RF ;-)

@petrok1rp254 Год назад

How about CW mode operation please?

@w2aew Год назад

Earlier versions of firmware had some issues with CW timing and sidetone generation, but very recent changes to firmware seem to address these quite well.
