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

Sorry, my comment was re QST, not RSGB. Bob — KK5R

Make that lower left. Time for some coffee.

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 — KK5R

Bob's LPF is in the lower right corner of the uSDX schematic. Jerry, KE7ER

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. Sent with

Thanks, Bob! I'm really looking forward to it. Jack, W8TEE

Jack, you have very nice images on your qrz.com webpage. Very nice...and impressive. I'm sure you will be adding to this forum considering your background in education and ham radio. I look forward to

November is available online now but the Reviews section in the TOC doesn’t list a uBITX as best I can see on my phone. I’ll look through the mag on a real screen in a bit. Scott ka9p Make

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

The Oct issue arrived about a week ago and there is nothing in it that I see on the ?BITX. My guess is it will be a couple of more weeks before I get the Nov issue. Jack, W8TEE

I just bought one of the VFO/SigGen kits from QRP-Labs and they already have a GPS disciplined option for it if you want to try it out. It is only 1PPS but apparently does the job. I haven't built my

Has anyone seen the latest RSGB's magazine? I believe it has a review of the ubitx.

That is indeed an interesting concept. I wonder if it would pass an FCC certification, though. A lowpass filter is needed, no doubt, and I don't see one. Nor AGC, etc., etc. But it is indeed

If you're interested in a truly amazing use of an Arduino in an SDR check out the uSDX transceiver /g/ucx -- 73 Bob? KD8CGH

I have for sale a few kits from my radio desk that just don't get used. *50w QRP-Labs Amp 40m* : Built and tested by me with added 24v fan. I will also include a hand PTT that plug's into the amp and

If you are using Firefox with add on noscript then give full permission to gropus.io and repeat and save your setting. No script messes up some things on my desktop. Raj

Worth trying, but the NEO-7M is very cheap and does not give a clean square wave. Any corrections in edge count to better agree with the satellite will disturb that square wave. In the discussion I

The December issue of QST has an interesting article about using an Arduino in a simple transmitter (Page 30). It is hardly as sophisticated as the use of the technology here but it may be of interest
