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

[@tav9755]

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

FX-4CR is nice little radio, I love mine. I also have the FX-4C it’s nice as well!!!

[@mnmmnm6718]

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

[@labcat73]

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

[@gerd3136]

Cool nice radio 😊. Thanks for sharing!

[@JimmyShot]

awesome video with the steps. Thank you

[@randytheapplianceguy8838]

Nice work

[@dean5263]

Very well done.

[@piconano]

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.

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

[@w2aew]

It can’t

[@vourkosdude]

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!

[@caulktel]

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]

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.

[@petrok1rp254]

How about CW mode operation please?

[@w2aew]

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.

[@petrok1rp254]

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

[@w2aew]

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

[@j204ever5]

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

[@JeffCowan]

Fewer spurious emissions

[@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.

[@w2aew]

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]

@@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]

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

[@ke4est]

Thanks for the video!!

[@wgxdz]

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

[@w2aew]

Likely anything shipped after September will include the new board. The maker sent the updated board to ALL purchasers of the early radios.

[@JeffCowan]

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

[@w2aew]

Several weeks ago

[@Mr_Meowingtons]

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

[@paullinnell]

Thanks for video!! De NØPL
