Exactly. #zbitx is not a SOTA radio, (except to warm your hands in cold weather as your 18650s drain). CW unuseable as of now: missed dits and dahs, strange echo after a few minutes (delayed RX processing?). Also, much heavier radio. Screen unreadable in a bright outdoors setting. Even with all the problems (birdies, unreadable in the sun, PCB-mounted connectors, less bands, etc.) my #trusdx is open-source and a better radio. No FT8 though (acoustically-coupled FT8CN). -
You wouldn’t think this would work but it does! #truSDX attached to a metal fence with Tomato wire and a Bluetooth adapter with the cheapest BT headphones, a 10Ah PD power supply and a #PackTenna. Makes for a great setup to adjust my antenna and hear feedback in realtime. #amateurradio #hamradio #radio #qrp #sota #pota #anker #hamradiodude #photo #photography #hammie #cwmorse #cw #baseus

Put together a small CW QRP practice kit for a recent trip. The key to this for me has been the #truSDX and this super rad USB-C PD to 12v barrel plug. PD seems to keep the battery on whereas USB-A 3 won’t. Funny enough non-fancy USB has no problem pushing out 5v all day long!

This means that the inevitable stress from external connectors and wires sometimes tears the connectors off the PCB, taking with them part of the PCB tracks.
Other QRP radios (QCX, some Chinese SDX's) have connectors mechanically fixed to their case.
My friend EA5IML and I have, in separate operations, fitted wire bridges between the connectors and components (inductances, an 7805 regulator).
Last night I could not figure out what was
wrong with the antenna connector. :(#trusdx (2/2)

It is the third time my (tr)uSDX undergoes surgery. This time, I could not revive it.
I've enjoyed it for nineteen months.
My (tr)uSDX had a number of known problems: an audio oscillation at high volume (even with headphones), birdies in the middle of ham bands (14286 kHz), no easy way to reach a split mode, etc.
However, it has a *design flaw*. The antenna connector and the power connector (among others) are directly soldered to the PCB but not mechanically supported.

#truSDX case getting printed, also a single lever portable morse paddle. #AmateurRadio #HamRadio

I am a bit curious now. This might be a summer project, building a #trusdx as #shackInABox setup with battery and atu into such a hammond aluminium case.

I did it! I ordered new shit. This time a #truSDX kit #tranceiver! I am still unsure if i want the #qrpguys metal case or if i want to have a shack in a box setup centered around this.
This is a 5 band #SDR tranceiver using an #atmega and some sort of PWRed pa, which makes it one of the most efficient trx i know of. Receiving quality is reasonable.

Don't get me wrong: the #trusdx, with all its known issues (birdies in some frequencies, audio coupling, etc.), is a great radio for its price. But the assembled version has an important design flaw that has got me off-air twice: connectors (the SMA antenna connector and the power connector) are directly soldered to the PCB with no or very little mechanical support from the casing. Strain applied to the connector pulls the PCB tracks, and they break, and repairing means rerouting connections.

I fried my Huntsville tablet. As a replacement I'm figuring out how to get out of Windows with #73Linux + Evolve III #jankapotamus laptop. Pretty much plug & play for #JS8Call with the #TruSDX and

So cute! It's just begging for a cuddle and a saucer of milk! 🥰
