And not sure why, but I cannot find the original message posted. It had a link to this video?So I'm posting the links to both of my Si5351 uBITX measurement video.? Direct measurement Clocks 0, 1,

I'm on a bad internet connection, no idea what's in the video. I assume the "original" code is appropriate for the uBitx, and not the screed you pointed to in post 24724 A Raduino with Bitx40 code

I like the little wheelchair they use for a logo.

Issue would also be to find a combined (isolated) female panelmount jack for these mikes. If you don't want to modify the wiring. The PTT between the two sleeves wouldn't work as both sleeves are

The reason I did this exercise (in the video) was to find out what the working raduino SI5131 output clocks measured. I have a not so well working raduino, from a BITX40, with original code installed,

This are the TDA2822Ms I received from China ordered on eBay

Cool guys. Yes, glad I wasn't actually going insane. lol jgaffke@...> wrote:

HI Qonita, I haven't seen any other replies so I'll throw in my two cents. If you already have the information you need you may safely ignore this post! :) WSPR is a low-speed protocol which really

What rig are you talking about, the Bitx40 or the uBitx? The Bitx40 has a 5 wire connector soldered into one end of the line of 16 holes at the bottom of the raduino, A cable assembly plugs into that

Wasn't obvious to me from your first post what you had measured that was different than Farhan's explanation. Sounds like you may have found that 33mhz is LSB and 57mhz is USB instead of the other way

According to the documentation the 1st oscillator tunes from 45 to 75 MHz to receive 0 to 30 MHz. Since the oscillator is higher than the received frequency this inverts the sidebands. LSB becomes

According to the instructions and the parts list there is a 5 pin connector that attaches to the back of the Raduino, I have to wiring but there is no place to connect it on the Raduino. Has this been

Ok, checked out the BITX40 explanation, and clearly the uBITX is a completely different giraffe and requires different math. If someone even wanted to try to do that I'd be grateful. I guess I might

Well, you've gave me the Farhhan explanation at his site :??"To invert the sideband between USB and LSB, the second oscillator is switched between 33 MHz and 57 MHz. " But that's clearly not whats

Sounds perfect. Let us know when it's done, and we'll all pile on to criticize your grammar. Many thanks for setting up that website! Jerry

I hate sitting through videos.? The math involved is addition and subtraction,? no need to solve any differential equations. The 12mhz crystal filter has a 3dB passband of around 11.996 to 11.998

Jerry I decided to both amend the original story (http://ubitx.net/2018/03/01/tda2822-problems/) and add a news item about Raj's experiment

And first of all, this uBITX works perfectly. It sounds great. Its very sensitive and has good tone quality. Literature says this :?"To invert the sideband between USB and LSB, the second oscillator

I must be gettin really old. I read it and didn't even think twice about it till Jerry mentioned it. Vince.

Hi Graham, Have a look here: http://ubitx.net/tag/rd16hhf1/ Marco - KG5PRT
