Re: Interesting QST article
I saw "one" LPF in the lower left-hand corner of the schemetic and some data on another page for other LPF's. But the uBITX is a complete rig for ham radio. I suspect that the radio would be a great receiver, though. (I still prefer the V6)... Bob ¡ª KK5R

Hi, It's in the December RadCom (vol 96, no 12). Arrived a day or so ago (UK). It's a good, favourable review. I can try and scan it later if folks are interested. Cheers, Dave.

Re: RSGB review of the ubitx
Nothing about it in the December issue, either. I've had a few submissions to QST and they were not published right away so they may still be finessing current and past issues. Bob ¡ª KK5R

Hi Bob: I just joined the group a few days ago and look forward to working on it. I've ordered a ?SDR kit, but hope to modify it for a TFT display and a Teensy T4 processor. I'm not very adept at EE stuff, but not too bad on the firmware. I'm looking forward to it. Jack, W8TEE
