Re: FT8
I tweaked my ubitx so I have an 'all in one' rig for FT8 and other digi modes, including CAT control (FT-817 emulation). Added an un-powered 4 port USB hub inside the rig and used a cheap USB sound

Re: FT8
The W on the Pi is very delicate.? I routinely knocked it out with playing with WSPR at 100mW using the TAPR shield.? Separating the shield from the Pi from 10cm jumpers fixed the problem with both

DIGITAL FREQUENCY READOUT
MAYBE I AM MISSING SOMETHING, BUT ARE ALL uBITX V4.3 RADIOS HAVE A ONE KHZ LOW READOUT. FOR EXAMPLE, IF I HAVE A STATION ON 7.150 SELECTED, IT READS OUT 7.149 FOR CLEAR RECEPTION. IS THIS NORMAL?

Re: Tool advice: contemporary oscilloscopes and Spectrum Analyzers
That's a very good deal for somebody, and a very kind offer. 20mhz of BW is good enough to debug stuff at 40 and 80 meters, and maybe a little higher too if you know what to expect. Suitable scope

Re: FT8
Hmm. Sounds like some future uBitx v5 may prove interesting. The QSX looks promising too, but not very hackable. Jerry
