Probably the same case we used:

It's all metal except for the "edging" which is plastic.

Seem to remember I had a similar issue with the S meter. I think  it was the firmare I chose  - I’d mistakenly used the firmware with the “_S” in the filename.

You can use any CC/CV charger set to the appropriate voltage and current settings.
I use a lot of the cheap dc-dc buck modules.
https://www.amazon.com/NOYITO-Adjustable-Regulator-Supply-Module/dp/B07G446KHJ/ref=mp_s_a_1_3?keywords=cc%2Fcv&qid=1555507232&s=gateway&sr=8-3

For the Turnigy pack, set the voltage to a hair under 12.6 and the current to 0.5A and connect to a DC source of 13.8V and it should charge just fine.  You can connect it directly to the discharge port.

As for balancing, I just plug one of these into the mini balance/charging plug every few charges.  It will drain the highest capacity cell slowly to balance the pack.  It doesn't need to be done every charge, but should be done periodically to maintain cell balance.

https://www.amazon.com/Turnigy-Battery-Display-Balancer-2S-6S/dp/B00USQXS1O/ref=mp_s_a_1_31?keywords=battery+balancer&qid=1555507626&s=gateway&sr=8-31

These will work with most any lipo battery pack, homebuilt or otherwise, as long as you have the right wire connections.

I also have a pack like the one KN6KB linked to, and it works great and is easier to use, but isn't really the best for building into a radio because of the power switch and unnecessary bulk, and you can't really cut out the power cable and replace with your own (like Power poles) unless you want to do a bit of surgery.

It works great as an external pack though!

For the Turning pack, I forgot to mention: you could always buy a ready-made balance charger if you want as well, but the buck converter and external balancer is more versatile for me.  It works great with solar panels, you can plug it into any wall wart of high enough voltage, or you could charge from your car battery on the go.

I have one of those cases, the panels are all steel.  Really the whole case comes across as kind of "cheezy".   The cases  I am considering for my uBITX are a Cheval SA from Thailand or possibly the Circuit Specialist Instrument case.



The Cheval case is of better design and quality but you have cost and delays associated with shipping from Bangkok.  Also at the moment, they are closed for a National Holiday week.

The cases from https://amateurradiokits.in/ are pretty neat and are pre-punched and come with all the associated goodies.  The selections available vary from day to day,  so far they haven't had the "one" I liked best available.  I think these are an excellent bargain considering the goodies bag they came with.

 I have been looking at Drok's sight this morning.. love reading the reviews 😶  found this Drok buck boost that looks like I can set to 12.x volts out and either plug in a 13.5v PS in the shack or a lipo or whatever battery.. on or off solar panel and it will give me 12.x volts all day..   I am no ex-spurt so if any of you see something I am missing I welcome the wisdom..  for a start I am thinking or one and then if it pans out that sending more power to the finals is a good thing I would consider a second one..   my (up purpased) case has room, I am planning seperate fast acting fuses for the raduino (1.5a) and main board (2a or 3a)... still sorting through the polarity protection options but I have power pole connectors for the power connection on the case..

The firmware with the "S" is the right version to use with the intention of wiring to A7 for a meter, no?  That's kind of the point of the designation that way.

Re: Audio hiss with random popping #ubitx-help #ubitx

Daniel Conklin
 

OK, so I finally had time to open it up and have a look. Sorry for the delay. It turns out that the hissy, click audio was from the wires going from the AGC board to the volume pot. I have them connected using header pins. They had pulled loose and were almost falling off. When I pushed them back on firmly the problem went away  The mic click/pop is still there but reduced, so I think it's back to near normal.

Raj,

In what way is the FY6800 a bit flakey to operate?
I'm very curious, as am on the verge of buying one.

Lots of the FY6800 reviews mention it is better than the previous product
(I assume the FY6600) in that BNC ground is not driven with a DC offset from power plug ground.
Some complain that it is not yet ideal, that BNC ground should be independent of power plug ground.
Also a complaint or two that the internal switching power supply is a bit noisy on the FY6800.
Any comments?

Webpage for the FY6800 says 1mv resolution, not 0.1mv.
Do the FY6800 knobs really allow 0.1mv resolution in setting the pk-pk amplitude?

Webpage for the FY6600 also claims 1mv resolution:
  "Small signal is particularly good,FY6600 can outputs1mVPP small signal, amplitude resolution is 1mV, and can be 1mVpp, 10mVpp, 100mVpp, 1Vpp and other different step value, the maximum range is 1mVpp~20Vpp electrodeless stepless regulation."
With a 12 bit DAC and 20v pk-pk max, DAC step size is 20v/(2**12) = 20v/4096 = 4.88mv,
so must have some sort of VGA after the DAC if it can generate an accurate sine wave that is 1mv pk-pk.

Would be interesting to pop one open, see what frequency the reference oscillator is operating at.
Should be possible to modify it to switch between the internal reference and an external
GPS disciplined reference coming in through an SMA connector on the back.
Though for most of us, the claimed 1ppm stability as originally built is good enough.

Jerry, KE7ER

Re: Case

Another thing to consider with the blue cases from eBay etc., the panels ARE steel, but the major problem is they are mounted in a plastic frame.  There is no continuity between the front and back panels with each other and with the rest of the case.  I have used 2 of these cases and to eliminate or at least reduce ground loops in the circuitry, I had to use heavy braid from each panel via a solder lug under the corner standoff(s) of the mounted uBITX board.  If you don't do this, no telling what will or will not work on the radio due to missing grounds if something isn't quite connected right and you might have weird results when tuning, keying, talking with the microphone, etc.

This isn't something you can ignore unless you are extremely lucky.
