Re: Kit-Projects ND6T Ubitx AGC
If I could ask for the same measurements that digger took that would be great.? The solution here is going to be either modding the ubitx to fix the audio issue or adding an amp for the boards that need it.? The attenuation range is based on how much af drive is given to the circuit. If you read nd6t's original articles you can see why the values reported by digger are just not cutting it! I'm personally just fustrated that some of you will have issues with our product. While it is a kit it's meant to just work. So thank you all for the support!

Re: Kit-Projects ND6T Ubitx AGC
i have a ubitx v4 with your AGC board installed. I also live in an amusingly noisy environment and I have relevant testing kit. :-P Let me know what you'd like and I'll go see if I can take some measurements for you. -adrian On Tue, 16 Apr 2019 at 09:26, KE2GKB via Groups.Io <tkeller=[email protected]> wrote:

Re: Homebrew li-ion battery pack into ubitx
¿ªÔÆÌåÓýSorry... I thought this was the same one I
purchased. Mine was: $~24, Prime Shipping, With charger. It claims 3000 mAHr but it is
probably closer to 2400 or so based on some comments. It has a
convenient disconnect switch and has a pretty well regulated 12 V
output.? Charger is rated at 12.6 v Out at 500ma.? (100-240 VAC
input). The battery has built in protection and regulation I
believe. Rick KN6KB

Re: Homebrew li-ion battery pack into ubitx
I followed KEGYC's link into Amazon for the Turnigy lipo 11.1v 2200mah 1.5c battery pack, see this question and answer:

Question: Does it come with a charger? Answer:? ?come alone without charger; No you will need to get a proper lipo balance charger; Does not it come with a charger. So it does not come with a charger. Needs a "balanced charger", they generally cost twice as much as this $22.99 battery pack. The Turnigy webpage on chargers looks like gibberish using this ChromeOS laptop: ??http://www.turnigy.com/chargers/ Any recommendations on a suitable charger for this battery pack?

Re: Kit-Projects ND6T Ubitx AGC
Digger do you have any other uBitxs? I currently do not have a good known noise source (Working on it! but alas the day job has its priority :( ) So it is currently out of my capability to make comparison measurements. I do know that those numbers are on the order of about 3x lower then they should be based on the non scientific measurements I have taken on my unit. -- Tim Keller - KE2GKB |
Re: Homebrew li-ion battery pack into ubitx
Rick:? Web site doesn't say it comes with charger--how does one charge it if it doesn't?? Seems like it might fit my BITX 40.

Re: POP!!

Now I haven't compared them, but they're dip relays and I use them in my CWid boards. MPJA.com has some for $1.29 ea, under a buck each when on sale. I usually keep no less than 10 on hand. There's a PDF data sheet with all the dimensions you can compare things to.

Oh, I did use one of them to replace a flaky relay in a Yaesu 757 and it works fine - it's in the receive part but should be ok for RF. Vince. On 04/16/2019 11:29 AM, Sam Tedesco wrote:

POP!!
Popping finals and now nanos on my beater v3 board. Started with 13.8v in...then goofing with biasing. Why?? I don't know. Curiosity and cause the trimmers didn't seem to be responding. Changed them out.
Anyway, going to replace the 5v reg, finals, nano, and relays. Still suspecting a bad relay, too. Anyone locate cheap relays? I don't care about harmonics... This board is not for the air. Thanks! |

The 60mhz version at $124.29 only does 60mhz on sine wave generation,

everything else is the same as the 30mhz version at $116.29 Makes sense, they can put a low pass filter on the output to extract a clean 60 mhz sine wave, Lots and lots of features, read the Banggood description thoroughly. I'm tempted.? ?? Jerry, KE7ER On Tue, Apr 16, 2019 at 07:36 AM, Jerry Gaffke wrote:

The FY6800 30mhz version does not save you much money. Gets good reviews. Searching for 6800 on Banggood mostly finds a bunch of gas masks. Jerry, KE7ER On Tue, Apr 16, 2019 at 04:19 AM, Raj vu2zap wrote: There is one with model number 6800 which is better and cheaper at Banggood. |
My uBITX is due to arrive by the end of the week and, like you, my head is full of ideas from trolling this group and the rest of uBITX on the net..? repeatedly I hear what Evan is saying.. I have an old aluminum phone system powersupply encosure that I may just have an open front on until I see how it goes..? currently think I will try the cat control from an android app or pc instead of better display..?
