Michael, would you provide a link to your kits? Thanks, Roy WA0YMH

Here is the STL file for my Bezel.? As most know, 3D printing is hit and miss. My kit includes the Bezel, Metric Flat head screws, sheet metal screws, ABS standoff, and ABS 1/8" spacers for using

Question here, what basically would it take to make these into a 9600baud or better digital transceiver?

Have been reports here of clone chips that inexplicably blow if fed more than 7vdc. Appears to be several clone brands that sell parts made from factory floor sweepings, other projects have been

Tim, I think I now understand the offset you were referring to. That's a good point, and this might be key to Gerald's problem of hearing different audio on USB than LSB. The answer, I think, is to

Nice case. Not sure you would want to open the discussion to a "case" discussion in General so I possibly apologize in advance, but the Brazilians are making some of the nicest cases I've seen. For an

I don`t think you were forceful at all, simply said what you thought. When you read the myriad of posts on the subject of the exploding audio chip it is easy to see a lot of the problem lies with the

very cool Larry, even if the Si4721 can't be used in a HAM band it can still be used as a "Handie Talkie" in the FM broadcast band within the limitations of the Part 15 rules here in the US.? -Justin

Well, I might’ve been a bit too forceful, but I wanted people to understand that creating a product out of thin air, manufacturing and shipping it all over the world is quite an undertaking. If all

Tim, Good, looks like you now agree with my ost 44182 that moving the VFO + BFO is a better solution than?moving clk1 + BFO. As I stated in post 44182, the original uBitx code only moves the BFO when

I agree with Gordon. I have gotten bad components from reputable suppliers such as Mouser and Digikey. It happens. It's annoying. But it's not Farhan's fault. Heck, I have even had component failure

Well I'm used to you criticizing what I write as if you don't understand it. Vince.

Well said Gordon. Vince.

Wow! Testy, aren't we? I know I said basically the same thing as you. I just explained it a little differently! It was not meant to be a criticism of what you wrote! tim ab0wr "Vince Vielhaber"

I faintly disagree.?? Might work, but you are better off moving the VFO and the BFO, not clk1 and the BFO. If moving clk1, you change where the signal we extract is hitting the 45mhz filter.

Did you even read what I wrote? If so, did you comprehend? You repeated the same thing I wrote. Vince.

WA6ISP has them for sale in his catalog list -$4.00 Larry- W8LM

I've built 2 "Handie-Talkie" type devices.Using DOJORI DRA818V VHF Band Voice Transceiver Module V1.21- I have found them on Ebay- in single lot quantities for $11. You program them with a USB to TTL

Jerry, This is a very complicated subject. The BFO, i.e. CLK0 *has* to be at the suppressed carrier frequency in order to properly demodulate the signal. In order to do PBT you would have to shift
