uBITX professional case

Amateur Radio Kits India, owned by VU3SUA. Is now producing a commercial grade aluminum case in a variety of different colours for the uBITX.


The case comes predrilled, with the cut out of the panel for the frequency display, ready to house the uBITX PCB. This sure makes the uBITX look the part in the shack. Complete with all the missing fittings, speaker, knobs, USB, SO239, mic skt, etc (the full list of parts is on the website).

Shipping starts early March.

A SWR power bridge for uBITX

A damp cold Saturday here at Rugeley, the postman has not long been and dropped off my January issue of QRP Quarterly- Journal of the QRP ARCI.

Something good has just caught my eye, especially if your into the uBITX right now.

This month there is an excellent article for a VSWR bridge for the Arduino, which confusingly KW5GP (Glen Popiel) appears to take all the credits? But it appears the article was written or most of it by KV4QB (DuWayne Schmidlkofer)? A better explaination of the confusion, might be to just nip down to DuWayne's Place  to understand what has actually gone on.


Why is this article good for the uBITX builder or users? Well at the moment there is no SWR/PWR bridge hardware built into the uBITX, although VU2ESE's Arduino code does appear to implement something for a basic S meter.

The article has  a full bridge directional coupler circuit, along with amplified outputs, which are then fed into the Arduino. Along with this, there is the code, that could be easily adapted to work with the uBITX Arduino. Anyway Duwayne, has been good enough to drop off the details along with the code at his Dropbox site here
