This year, I’ve had a couple of readers very kindly offer to loan me their FX-4C transceivers to take to the field and review.
Those offers have been very temping because I’ve only heard positive comments from owners of this wee feature-packed SDR transceiver designed by Yu (BG2FX).
Earlier this year, I learned that Yu was retiring the FX-4C and would be introducing two new radios, so I decided to hold off on an FX-4C review for this reason.
My buddy, Don, informed me that the new radios were now available for pre-order, so I checked out the option on Yu’s website, and placed an order.
Details (features and specs) are still a little sparse because BG2FX is still finalizing the design and lining up production, but here’s a snapshot of the two models based on Yu’s preliminary info:
I was very pleased to read that my buddy John (AE5X) has one of these on order.
The FX-4CR can push 15-20 watts on most bands according to John, which is most impressive for a one pound radio that fits in the palm of your hand! It covers 80 – 6 meters, sports a color screen with a 48 kHz wide waterfall display, an internal sound card for digital modes, built-in speaker and microphone, 9 – 18 VDC input range, and even sports Bluetooth!
That’s an impressive array of features for $550 US (on pre-order).
I pre-ordered the FX-4L and am told by Yu that it should ship by end of October or early November 2022. I wouldn’t be surprised if that’s an optimistic projection.
The FX-4L is essentially a more basic QRP version of the FX-4CR; it’s maximum output power is around 5 watts.
It’s very similar to the FX-4CR in many respects: it has the same display from what I can tell, covers 80 – 6 meters, has a wide voltage range 9 – 18 VDC, sports an internal sound card, and is super compact and lightweight.
The FX-4L doesn’t appear to have Bluetooth. Lu doesn’t mention a built-in speaker or microphone, but there’s an obvious speaker grill and even a small hole that might be a microphone. I’ll try to confirm this. Yu does note that there’s room in the chassis for the user to add a battery or ATU.
I’ve been more interested in the FX-4L because, as you likely know, it’s very rare for me top operate over 5 watts of power.
That said, I certainly see the appeal of a 15W+ radio like the FX-4CR.
(Many thanks to Yu for sharing all of the FX-4L photos above.)
I’m really looking forward to checking out the FX-4L and also reading AE5X’s assessment of the FX-4CR.
I’m curious if anyone else has pre-ordered one of these radios. Also, if you’re an FX-4C owner, I’d love to hear your comments!
