Strange how an old platform like the FT-817 STILL does not have any real competitors, after all this time. John'KK4ITX Click Here for Zephyrhills Area Amateur Radio ClubMany of life's failures are

Shirley: You're right about the T41-EP. However, a smaller display, half the power output, tri-band, and putting things on one board might get it small enough to be a possibility. I actually like the

Got it working!!! I had to do a factory reset after installing the new firmware chip. Thank you for all the help!!! 73 Ryan NC4RA

Indeed! I look forward to seeing the QSX someday. What is missing is a physically small radio for field use, something to compete with the FT-817, KX2, KX3, and the Xiegu rigs. We have the sBitx and

I have observed rather strong spurs +/- 1 MHz around the carrier on my Rev 3a S/W ver 1.04 T1 3:3 9V QDX with trace cut per V 1.12 of the Asm Manual. These spurs are right about the required –43 dBc

RF cannot effect software. But it can screw up the HARDWARE running it (notice the difference) ;-) Q.E.D.

I noticed the fourth year of the QSX announcement has sneaked quietly past us. A progress report would be nice… The QDX-mini was fun but despite mods for wspr rx bandwidth still single band…and

Thanks! I am fine with being informed!

FWIW, that's a Chinese knock-off of a QRPGuys design. For $30, you can have the original instead of the counterfeit. My intent is to inform, not judge or criticize. 73 de KC6WOG

This would be the equivalent to the MFJ-1820T. I purchased it on EBay for $20. I have the MFJ-1840T, but having trouble with high SWR. Richard N6IJK

Charles, I can see your point now.? Yes, you are right.? The U3S kit has all these parts. But there is a good description of needed parts in the schematics and BOM. And a comment: I do not know the

Which telescopic vertical is it? I have a MFJ1899T but this looks different... Never used indoor however, once I tried at home and got just a lot of QRM...

Coffee money for Hans on the way! https://www.buymeacoffee.com/g0upl -- Sverre LA3ZA http://la3za.blogspot.com

Thanks Hans and Alan! No I didn't do the cut, but I have now. Audio gain at the default 54 dB is now OK, USB suppression is fine (see plot), but receive current is still a bit high at 175 mA, but I

Sverre, Did you do the PCB track cut? 73 Alan G4ZFQ
