It amazing just as it is!! Been listening to 40M CW while I work on some photos I took. I swear the receiver is as good as my FT-1200. Jack, W8TEE To: [email protected] Sent: Wednesday, December 13,

Jack, really interested when you get the uBitx boards available.

Re: uBITX Case
all sounds good, except I would rather have a froont firing speaker. don't know what the group thinks about that, but remember how good they sounded?

Re: SDR dongle for spectrum analyzer with signal from Bitx40?
Thanks Jack! I am very enthusiastic about the possibility. That would be a capability I could not otherwise afford. And a great learning experience trying to assemble it without letting out the magic

You can make an encoder free running like a pot, just remove the ball. I did it with an encoder that I use to tune my PC with HDSDR. Phil - G7BZD jjpurdum@...> wrote:

Re: SDR dongle for spectrum analyzer with signal from Bitx40?
The really cheap SDR dongles (meant for DVB-T television reception, $10) can get down to 30mhz without a downconverter (as I recall). They only have an 8bit A2D converter, so reception with the uBitx

Re: SDR dongle for spectrum analyzer with signal from Bitx40?
That's the reason for the additional horsepower. I will admit that I'm getting into an area of development that's new to me, but one that I'm very excited about. The goal is a 5" panadapter

Re: SDR dongle for spectrum analyzer with signal from Bitx40?
Jack Any possibility of getting the waterfall display functionality into your next revision of W8TEE TFT? It would make the uBitx a wonderful piece of kit for family outings. -John

It's alive!
It's a mess, but I have my ?BITX working now. I wanted to get it working before I put it in a case which is why there's wires all over the place as I trimmed none yet. That will happen when I move it

Re: uBITX Case
All sorts of ways to do this. If the case is metal, I'd attach the IRF510's directly to the metal case using standard TO220 insulating washers and heat transfer compound. ?The case is the heatsink.

Re: uBITX Case
There have been many posts over the years that talked about making or purchasing suitable cases for various BITX rigs. All involve some amount of measuring and cutting appropriate holes. Simplest case

Re: uBITX Case
The heatsink needs to be insulated from the case. Probably best to leave a little space behind it!

Thanks for the input everyone I spent a couple minutes just sketching up something really quick based on some of the dimensions. This is a really really rough draft/sketch. *Everything will change*

Re: uBITX Case
I guess from the comments that a pre-punched case sounds really good. To solve the problem of the antenna connector, don't punch it, leave it for us to pick which one to use I like BNC but all my

Re: uBITX Case
Jeff, Since both the uBitx and Bitx40 kits come with a BNC, that's what you should specify. Anyone who absolutely has to have a UHF connector can easily and quickly enlarge the RF connector opening
