For the power meter function, I decided on a maximum reading of about 15 watts. Technically, Ubitx is very well designed. Then when I finally did, it took another hour to tailor the S-Meter sample points in uBITX Memory Manager so that the S-Meter more or less matched what I was seeing on my the Icom IC-7300 via an A verses B comparison. It will tune 11m but to be useful it would need some sort of low level PA. It is a compact, single board design that covers the entire HF range with a few minor trade-offs. So OK the concept of the Bitx and uBitx is to operate QRP and with the new design of the uBitx having 10 watts is an excellent power level for making contacts. So I added a series of direct menu buttons like STEP, VFO A/B, BAND, MENU and one hole (thought I had one button more on stock which I didn't) to the uBitx. Since ordering and beginning the slow-motion assembly of my uBITX - interrupted by Santa and work - I've had a lingering voice in my mind telling me that a 3-30 MHz $110 transceiver can't really make QSO's or even receive well.
