Evan + Others — your help desk like support enables MANY of us to accomplish what, on our own, we could never do. Evan’s observations ‘bout where to find help on a specific topic/issue are spot on. Se

Searching my log found 4 digital qsos with Steve. And never the same mode twice. Check out the spread of digital modes. He is a madman of FT8 and (!) non-FT8 modes. My kind of operator! Three cheers!!

Hello all! So all works grandly with the hard working long suffering V4 except for 30m on TX. Almost no power. When I look at the schematic, it’s not obvious (well to me!) what relay/filters define th

Tim — I wired the exact same config with a passive usb hub so only one usb connection was required. No audio cables, no dual usb cables, it was grand. Two key points: wire in a simple DPDT front panel

Local winlink fans suggest the vara modem is a better winlink connection glue. Just FYI. Don km4udx

George, the issue may be computer failure to send TX over CAT. You'll likely have to double check USB/CAT configuration. Alternative: use Fldigi to work RTTY. There are lots of great configuration hel

Jamie — what do you use for a screen? Can you see the Fldigi (etc) well enough??

Evan — thank you for your thoughts! I’m busy breaking/fixing the gear I have. I can happily wait. thanks again!! Don km4udx

Evan — if you had to SWAG on most likely appropriate sort-of time frame for AF’s new SDR style Pi centric rig, when would that be? thank you oh seer…! Don km4udx

Alex -- this is hysterical. A few thoughts for your reflection based on my experience with my uBITX, and the multiple uBITXs in our local radio club. 1. The lack of built in high SWR protection circui

Hello all! I was feeding my uBITX audio into a audio spectrum display (yes I was tweaking the BFO). The audio spectrum display shows a good spike at 3.8khz. Same spike on all bands, but lower relative

Evan’s guidance is sound! My V4 build had the RF-driven TX-lock-on bedevilment. Why? My poor antenna, cable, tuner, connector mismanagement. When that was fixed, TX/RX CAT-based switching was crisp an

Ian — I’d be honored to deploy your uBITX goodies for radio exploration and fun. Don km4udx 571-225-6180

Arv was very kind helping this utter NOOB. When I picked the uBITX as my gateway "rig" for amateur radio, I was driven by two principal considerations. First, the multiband, accessible, affordable, ki

Well done! So the input to your 2n2219a is your homebrew? Did you have to lower the output of the 510 at that point? Or is the input to your lovely amp starting someplace else?

My ill informed 2 cents. It doesn’t support MFSK or any multi simultaneous tone mode. but dominoEX and THOR and Field-Helschriber are all variations of single tone schemes? So they could work, maybe?

Feld-Hellschreiber is a lovely if unusual duck working somewhat like CW with a single tone? Would this mode work? And DominoEX is also a single tone, maybe? When I look at THOR it seems also to be a s

JS8Call is a major upgrade to the FT8 type schemes. You can exchange actual content beyond FT8 call/grid/etc. And the msg control functions are amazing. Store and forward, acknowledgments, defined hop

When we do the "Ashar Interface Method (AIM)", we are using a sound card, it's on the motherboard. Many of us use AIM and it works perfectly! When the audio jacks on my tired computer broke (thanks ki
