Vintage Tech: FX 4C SDR QRP Radio

The tiny China-made QRP rig has some great reviews. Here is my unit running FT8 and some phone contacts on 20 Meters. I was on a ZS6 flat top Dipole about 40 feet up. During a G2/3 storm.

Would be interesting what makes integrating a tuner such a difficult task. Some transceivers have it, but such goodies as IC-705 and this one do not. Of course it would add to the size, but it would be worth it.

Was curious about this radio since you mentioned it on the repeater. Looks interesting! Oh and QRP is <5w :)

Would be great if you could do a video on how to set this rig up on FLDIGI. I was playing around with mine today. Managed to get it working with WSJTX and JS8Call. I'm still working on FLDIGI. I think you're meant to use C-Media PTT for rig control. I was able to get it to key up transmit to call CQ but couldn't see any incoming signal on the waterfall.

BTW, I find that the SSB audio distorts when I receive some strong stations with the FX-4C. Apart from turning on the attenuator, is that anything you can do about that?

Hello, I saw on google a model that has a stripe drawn near the AF and Tune buttons at the top. What is the difference between them? To be another lot?. I have one like yours bought from AliExpress. I hope it's not fake

Hello, I ordered an FX-4C SDR QRP Transceiver and I cannot operate in 3 650 kHz, in Romania this frequency is used, I can do something so that the Transceiver can transmit there as well. I am waiting for your message, I would like with a software if possible. Looking forward to hearing from you

What program are you running on the Mac?

On your Mac version of WSJT-X you set Radio to None. That means you are not using Cat control? You set the 14.074 frequency Manually?
