Carl did a nice job. I lined mine with copper foil to reduce interference. Others may be in a better position to comment on whether it is necessary or not.

I have updated my PDF File as a result of questions in assembling the uBITX in my Case.  After I post my PDF File on the forum: for a couple of days I get request fir the case and questions.  It seems the it falls off the radar until I post again.  I am getting good reviews from those who ordered my case so take a look: you may want one.

They are salvaged from new computer battery packs.

What kind of 18650 batteries are you using?  E-Cig batteries are
designed for an intermittant high current drain while keeping their
voltage up.

The ones I have are max 4 amps.

We used one at our repeater site and it has worked well.

HI Group.
I am about 2 days away from placing the order with the manufacturer for these boards.
I would like to know what people are most interested in:
1: bare through hole PCB
2: bare SMD PCB
3: PCB + all TH parts(kit) self assembly.
4: Complete ready to run assembles tested and FW loaded.

Thanks.

You might consider adding pads for an AD8307, driving a Nano analog pin.
Very cheap on ebay.  Then this is a sweeperino, and a calibrated S-meter.
Creeping featurism at its best.

Re: Raduino Replacemnt, COMING SOON!

HI Art,
No firm prices yet, But I dont plan on making anything out of this, just cover the costs and help out fellow BITX lovers...
Bare PCB I am aiming for $2 +$3 postage international, AUS will only be $1 shipping, all just preliminary costs...
Kit, I'm thinking $25 + postage, will be more as I cant use a flat envelope.... Might take awhile as I will have to source all the parts, Honestly you are better of just getting them locally/ebay...
Fully assembled, will have to look at the time, but maybe $30+ post... Same as above with times...

I am thinking I might order 10 of SMD and maybe 20+ TH, I want to build SMD, and the rest are forsale. and 10 HPF...

Also, makes a dandy tool for debugging RF sections of the rig.

Jerry, I like this idea, hmm, i have 2 days to get is implemented... Ill run it off A7 ,wDont effect anything if you leave it off.and yes be great for S meter...

One of the great things about using RDF16HHF1s is the tabs are at ground potential, so no need to insulate them from the heatsink.
